Safety SAFETY HAZARDS – VITON SEALS

WARNING

O-rings and other seals manufactured of Viton material (fluorine rubber) produce a highly corrosive acid (hydrofluoric) when subjected to temperatures above 315°C (600°F).

This contamination can have extreme consequences on human tissue since it is almost impossible to remove after contact.

The following procedures are recommended when inspecting equipment subjected to high temperatures such as fire:

Wear a suitable hearing protective device such as earmuffs or earplugs to protect against noise.

Prolonged exposure to loud noise can cause impairment or loss of hearing.

• Visually inspect any seals or gaskets which have suffered from heat damage. They will appear black and sticky. If these are found, DO NOT TOUCH! • Determine the material composition of any seals or gaskets. If fluoro-elastomer seals (Viton, Fluorel, or Tecmoflon) have been used, the affected area must be decontaminated before undertaking further work. Natural rubber and nitrile materials are not hazardous.

• When approaching an operating machine on foot, stay well clear of the machine until the operator recognizes your presence. Make sure that all harvesting equipment has been shut down before advancing to the machine.

• Disposable heavy duty gloves (neoprene) must be worn and the affected area decontaminated by washing thoroughly with limewater (Calcium Hydroxide solution).

• Any cloths, residue and gloves must be safely discarded after use.

NOTE: Burning discarded items is not recommended except in an approved incineration process where the dangerous products are treated by alkaline scrubbing.

• Keep a first aid kit in an easily accessible location on the vehicle at all times.

OFF OFF

ON ON 24863A R0

• When servicing or repairing equipment, turn OFF the engine, turn OFF the battery disconnect switch, and lock out the switch in accordance with local regulations.

• Never use your bare hand to check for fluid leaks.

Fluid leaks under pressure may not be visible. When searching for leaks, wear work gloves and use a wrench or piece of wood to move hydraulic hoses.

Do not grab hold of hydraulic hoses. Wear safety goggles for eye protection.

• Before servicing the electrical system, remove the negative (−) battery terminal cable (to the starter motor) from the battery.

• Install a DO NOT START ENGINE sign on the operator cab door and in the engine compartment when making repairs to the machine.

• Pressure can be maintained in a hydraulic system long after the power source and pump have been shut down. To relieve pressure, relieve trapped pressure from the accumulator where applicable and disconnect hoses before performing work on components. For the procedure to relieve pressure, refer to the machine operator's manual.

• Before performing maintenance or repair work on any equipment, consult the manufacturer’s instruction manual and follow recommended procedures.

• Prior to welding on the machine, clean it and have a fire extinguisher at the welding location. Attach the welding machine grounding clamp so current does not pass through bearings, especially the pivot bearing. Also, disconnect the battery positive terminal.

• Do not change any pressure or relief setting unless authorized instruction has been obtained.

1.6

Tigercat Power Clam Grapple

Safety

• Use the proper tool for the job. Repair or replace worn or damaged tools including lifting equipment immediately.

WARNING

• Keep your hands, feet, head, and loose clothing away from power-driven parts. Tie long hair behind your head. Remove rings and other jewellery to prevent electrical shorts and entanglement in moving parts.

• Be aware of machine pinch points that could cause injury. Never place body parts within the range of motion of the machine's working parts.

Hot fluids and machine surfaces can cause serious burns.

• Before servicing the machine, allow the engine cooling system, fuel system, exhaust system, hydraulic system and machine surfaces to cool down.

• Use a thermometer to check surface and system temperatures to ensure it is safe to begin service work.

• Wear proper safety equipment such as safety glasses and gloves during service.

• Do not begin service work until the surface or system temperature has cooled down to below 38°C (100°F).

• If the engine is running inside a building, ensure that sufficient ventilation is available to prevent a build-up of toxic exhaust fumes. Run the engine only when it is necessary for testing or adjustments.

• Work in a ventilated area. If it is necessary to run an engine in an enclosed area, use an exhaust pipe extension to remove toxic exhaust fumes.

If you don't have an exhaust pipe extension, either work outside, or open the shop doors.

• Never service the grapple with the engine running.

• Never access the attachment in the raised position.

1.7

• Dispose of fluids properly: • Do not pour fluids into the ground, streams, ponds, or lakes.

• Before draining fluids, know the proper way to dispose of them.

6. Turn OFF the battery disconnect switch and lock out the switch in accordance with local regulations.

7. Relieve hydraulic pressure in the system. Refer to SECTION 1 of the machine manual for instructions.

Hydraulic and diesel fuel systems on forestry machines operate at very high pressures, often 207 bar (3000 psi) and above. If a loose connection or a defect in a hose occurs, a fine, high velocity stream of fluid will result.

Even for systems pressurized to as little as 7 bar (100 psi), this fluid stream can penetrate human skin as if it were a hypodermic needle.

Initially, an accidental fluid injection beneath the skin may only produce a slight stinging sensation. There is a danger that you will tend to ignore this, thinking that it will get better with time. Most often, it does not! Within a very short time the wound may begin to throb painfully, indicating that tissue damage has already begun.

Similarly fluid injected directly into a blood vessel can spread rapidly through your circulatory system. The human body has little ability to purge injected fluid.

Time becomes critical as tissue damage progresses rapidly. The longer you delay getting professional medical attention, the more damage can occur.

Although fluid injection accidents are rare, the resulting injury has on occasion required the amputation of a finger, a hand or in some cases the entire limb. The longer the delay in getting professional medical aid, the further up the limb the tissue damage can spread. An injury of this type can become very serious or even fatal if not dealt with promptly and properly.

Safety

IN THE EVENT OF A SUSPECTED FLUID INJECTION INJURY

GREASE INJECTION INJURY WHEN USING PNEUMATIC GREASE GUNS

• Report the injury to your supervisor immediately.

Pneumatic grease guns can deliver grease at pressures from 17 – 400 bar (246 – 5801 psi). It takes less than 7 bar (100 psi) to inject a substance through human skin.

• Seek professional medical attention immediately.

The best defence against suffering the effects of fluid injection is to prevent the accident from occurring in the first place.

Get professional medical treatment immediately after any type of injection injury.

SEARCHING FOR POSSIBLE FLUID LEAKS • Do not search for leaks with your bare hands. Wear thick protective gloves.

• Wear safety goggles for eye protection.

• Keep all body parts well away from the area being investigated for leaks.

Provide the physician with information on the type of grease, the pressure setting of the gun, and similar details.

The amount of fluid injected, type of fluid (or material), pressure at which it was injected, and the elapsed time between injection and surgery all influence the chances of successful treatment for this type of serious injury.

Prior to using a high pressure pneumatic grease gun, perform the following: • All operators of high pressure pneumatic grease guns MUST be trained in the hazards of its operations and the treatment for such injuries.

• Use the end of a long piece of wood to move hoses or other obstacles.

• Place the end of a long piece of wood in the suspected path of any fluid stream. Do not use any part of your body.

• Do not operate a high pressure pneumatic grease gun unless you have been trained in the proper operation and are aware of all safety precautions of such a tool.

• Wear protective clothing such as gloves, safety hat, and safety glasses.

• Inspect all parts of the grease gun for wear and tear and replace all worn or damaged parts.

• Recognize the source of the leak and the fluid streaming from it may be very small and not easily visible. You may only be able to see the fluid that accumulates as a result of the fluid stream.

• Install protective shrouds on all grease gun nozzles as safety devices.

• Remove dirt and grease from grease fittings prior to greasing.

WHEN PERFORMING SERVICE WORK • Stop the engine and relieve all diesel fuel or hydraulic pressure before disconnecting any lines or otherwise working on the system.

• Do not grab any hydraulic or diesel fuel connectors or hoses when they are subjected to pressure.

• Verify that hoses are rated for the pressures to which they will be subjected.

• Do not use any hoses that you suspect could be defective.

1.9

• Replace any defective grease fittings on equipment with new fittings immediately.

• When badly positioned fittings are identified, replace them with angled or swivel fittings for easier access.

Safety

LIGHTNING SAFETY AWARENESS WHAT IS A LIGHTNING STRIKE? Lightning is a discharge of the electricity produced by a thunderstorm. As the thunderstorm develops, many small particles of ice within the storm clouds bump together. These collisions create a positive charge at the top of a cloud and a negative charge at the bottom.

As this continues a second positive charge builds up on the ground beneath the cloud, concentrated around high objects such as hills, trees, buildings, equipment and even people.

When the difference between the electrical charge in the cloud and on the ground becomes great enough to overcome the resistance of the insulating air between them, an electrical current flows instantly. This is a lightning strike.

The electrical potential in a lightning strike can be as much as 100 million volts. Lightning strikes can occur over very large distances, even as much as 60 km (37 miles). Lightning travels both in front of and behind a thunderstorm and so strikes happen even when rain has not started or has stopped. Lightning can hit in the same place, many times and often spreads out over 18 m (60 feet) within the soil around the strike point.

Thunder always accompanies lightning. When lightning occurs, the air through which it travels is instantaneously heated to a temperature more than 28,000°C (50,000°F).

The air expands rapidly due to this heating, then quickly contracts as it cools. It is this contracting shock wave that we hear as thunder.

In many areas of the world, lightning strikes are second only to flooding as the greatest cause of storm related deaths and injuries. Although only 10% of lightning strike victims are killed, virtually all from cardiac or respiratory arrest, over 70% of those that survive suffer severe, life-long injury and disability. The symptoms of a lightning strike include memory loss, fatigue, chronic pain, dizziness, sleeping difficulty and the inability to complete several tasks at one time.

Tigercat Power Clam Grapple LIGHTNING SAFETY In spite of the popular myth that being struck by lightning is an unlikely event, the facts show that lightning strikes occur frequently. As a result loggers are at high risk because their work is outdoors and close to known strike points such as tall trees and heavy equipment.

Loggers can increase their chances of avoiding a lightning strike by following a few simple safety practices: • Designate a member of your crew to: • Monitor daily weather forecasts • Observe local weather conditions • Alert all other members of the crew when a possible lightning threat develops • Don’t start or continue any work that cannot be stopped immediately, when a storm moves nearby.

• Anticipate a high-risk situation and take action early by moving to a low-risk location. Do not hesitate. If there is lightning, you are in danger.

• Obey the rule - If you see lightning, Flee. If you hear thunder, Clear. Do not follow the now obsolete guideline to take shelter when the time between seeing lightning and hearing thunder is 30 seconds or less. This does not provide sufficient time to ensure safety.

• Remain in your safe location for 30 minutes after the last sight of lightning or the last sound of thunder.

The safest location during lightning activity is inside a fully enclosed, substantially constructed building, a house, office, school, shopping area, etc. These are the safest because of the electrical wiring and plumbing they contain. Should lightning strike, the electrical current will travel through the wiring or plumbing into the ground.

When such a building is nearby, always seek shelter there first.

Unfortunately loggers do not often work close to buildings and therefore other alternatives need to be considered.

Sheds, weather shelters, hunting blinds, tents and other partially open or small structures are not safe against lightning strikes as they lack the electrically grounded components of larger buildings. They are intended for sun or rain protection only. Do not seek shelter from lightning strikes inside these structures.

1.10

Tigercat Power Clam Grapple

Safety

The second safest location during lightning activity is inside a fully enclosed car, van, truck or bus with a metal roof and metal sides. The electrical energy of a lightning strike to these vehicles is carried to ground by the conducting outer metal surfaces. This is called the skin effect.

IF INSIDE A MOTOR VEHICLE OR FULLY ENCLOSED ROPS EQUIPMENT CAB • Under no circumstances whatsoever step outside of the vehicle or off the equipment to move to another shelter. Very dangerous electrical pathways to ground may go through you.

Do not seek safety from lightning strikes in vehicles with fiberglass or plastic body shells or in convertible top vehicles. None of these are safe, as they do not offer skin effect lightning protection.

• Shut down all operation, turn off the engine, close all doors and raise all windows.

Heavy forestry equipment such as a skidder, loader, feller buncher, forwarder, etc. with a fully enclosed Rollover Protective Structure (ROPS) cab take advantage of the skin effect and are therefore safe in electrical storms.

• Do not touch any metallic objects referenced to the outside of the vehicle. Do not touch any door and window handles, control levers, foot pedals, steering wheels, cab interior walls and any other inside to outside metal objects.

• Sit squarely in the seat with your hands in your lap and your feet flat on the floor mat.

• Do not touch any radio or telephone connected to an outside antenna.

However machines with a rollover canopy only are not safe against lightning strikes as they are open to electrically conductive rainwater and do not benefit from the skin effect. Operators of this equipment must abandon their machines and get to a safer location before lightning strikes.

IF YOU ARE CAUGHT OUTSIDE AND HAVE NOWHERE TO GO • Avoid wide-open areas where you project above the surrounding landscape.

Note the rubber tires on motor vehicles and heavy equipment do not increase safety from lightning strikes.

Lightning has already travelled a great distance through the air to strike the vehicle. In comparison a few inches of rubber in a tire offers absolutely no additional insulation.

WHAT TO DO IF YOU ARE OUTSIDE AND SEE LIGHTNING OR HEAR THUNDER

• Seek shelter in a low place, such as a ditch, ravine, valley, canyon or cave.

• Get away from open water such as ponds or streams.

• Do not take shelter under any isolated tall trees or small groups of trees.

• Seek shelter amongst the dense, thick growth of the shortest trees.

• Avoid entering any small enclosures or shelters.

• Do not seek shelter under any motor vehicle or heavy equipment.

IF YOU CAN, GET INSIDE Run to the nearest building, motor vehicle or fully enclosed ROPS equipment cab immediately. Being anywhere outside is not safe.

• Keep clear of any materials that can conduct electricity such as wire fences and gates, metal pipes, poles, rails and tools.

IF INSIDE A BUILDING • Don’t watch the lightning storm from open windows or doorways. Stay in inner rooms.

• Stay well away from corded telephones, electrical appliances, lighting fixtures, radio microphones, electrical sockets and plumbing pipes and fixtures.

• Stay at least 15 m (50 ft) away from metal objects such as a fuel tank, a vehicle or machinery without a cab, motorcycle, ATV, etc.

• Stay at least 5 m (16 ft) apart from any other members of a group so that lightning won’t travel between you.

• Do not use the telephone except for emergencies.

1.11

Safety WHAT TO DO IF YOU FEEL YOUR SKIN TINGLING, YOUR HAIR STANDS ON END, LIGHT METAL OBJECTS VIBRATE OR YOU HEAR A CRACKLING SOUND

Tigercat Power Clam Grapple

FIRE PREVENTION

• Lightning is probably about to strike. You only have a few seconds to act.

• Put your feet together. Crouch down like in a baseball catcher’s position. Hold your head down.

Cover your ears to protect them against the noise of the thunder.

• Do not lie flat on the ground. By touching as little of the ground as possible, the lightning may not move across the ground to you.

WHAT TO DO IF A CO-WORKER HAS BEEN STRUCK BY LIGHTNING • The victim does not carry any electrical charge.

There is no danger to anyone helping this person.

You can touch him or her immediately.

• Call your local emergency response telephone number immediately.

• If the victim has no pulse, their heart has stopped or they have stopped breathing, call for professional medical help immediately and then begin administering appropriate first aid. Use a portable defibrillator if one is available (as required).

• Be careful about staying in the storm to take care of the victim. You can get hit by lightning too. If you can, move the victim to a building as soon as possible.

• To further increase your awareness about lightning safety, see the following web sites: • National Weather Service Lightning Safety http://www.lightningsafety.noaa.gov • National Lightning Safety Institute http://www.lightningsafety.com

When working in a forest environment, it is impossible to prevent combustible debris from collecting in tight corners of the machine. This debris may cause a fire.

However, when mixed with fuel, oil or grease in a hot or confined place, the danger of fire is greatly increased.

The following fire prevention guidelines are meant to supplement the operator’s fire prevention efforts. In no case are the guidelines to be used as, or assumed to be, replacements for diligent operator efforts at preventing fires.

These guidelines will help to keep your equipment up and running efficiently and keep the risk of fire to a minimum: • Maintain a charged fire extinguisher on the machine at all times and know how to use it.

• Remove debris and blow out dust regularly from the air intake doors, engine radiator and charge air cooler, hydraulic oil cooler, diesel fuel cooler and air conditioning condenser core to prevent overheating of the engine and hydraulics and to maintain efficient operation of the machine. Refer to COOLER PACKAGE, CLEANING in SECTION 3 of the MACHINE OPERATOR'S MANUAL. • Blow off all forest debris and fine organic material accumulated near hot engine exhaust components (turbocharger and exhaust manifold as well as exhaust pipes and muffler) at the completion of each work shift or more frequently when working in logging conditions where large amounts of combustible forest debris are present. Visual inspection is vital after blow-off to ensure thorough cleanliness. Engine exhaust systems provide numerous small pockets where sawdust, small wood chips and other flammable forest debris can gather.

Even small accumulations close to hot exhaust components can ignite and smoulder. If dislodged this smouldering debris can fall into other areas of the machine and thereby spread a fire.

• Clean out all accumulated forest debris (twigs, pine needles, branches, bark, leaves, sawdust, small wood chips) and any other combustible materials from inside the machine belly pans or lower machine structures as well as from areas in proximity to the engine, fuel and hydraulic oil systems no less frequently than at the completion of each work shift.

1.12

Tigercat Power Clam Grapple

Safety

• Inspect the machine regularly for any signs of diesel fuel or hydraulic system leakage. Check for worn or eroded fuel or hydraulic lines before starting up any equipment.

• Clean up any grease, diesel fuel, hydraulic and lubricating oil accumulation and spillage immediately.

• Steam clean the engine, hydraulic pumps, transmission, brake, fuel and hydraulic oil tank compartments and all machine belly pans at least once a month or more frequently when working in logging conditions where large amounts of combustible forest debris are present.

• Use only non-flammable solutions for cleaning the machine and components.

• Inspect the exhaust system daily for any signs of leakage. Check for worn, cracked, broken or damaged pipes or muffler. Also check for missing or damaged bolts or clamps. All exhaust leaks or defective parts must be repaired immediately.

Engine exhaust leaks can cause fires. Do not operate the machine until the exhaust leak is repaired.

• During daily operation of the machine, the occurrence of exhaust leaks are usually accompanied by a change or increase in engine exhaust noise levels. These audible warnings cannot be ignored. When exhaust leaks occur during operation, shut down the machine immediately and do not put it back to work until the necessary repairs have been completed.

• Park the machine at least 15 m (50 ft) away from other equipment at the end of each shift.

• Do not leave the machine parked with the boom or grapple suspended off the ground. If supporting hydraulic hoses burn through during a fire, they will inject pressurized hydraulic oil into the fire causing the boom and grapple to fall rapidly to the ground.

• Turn OFF the battery disconnect switch at shutdown to de-energize all electrical circuits.

• Remain with the machine for at least 45 minutes at the end of operations while the machine cools.

• Remove all keys, lock equipment and fuel fill cap at the end of operations to reduce the risk of vandalism.

• Be cautious when smoking. Do not permit an open flame, a lighted cigarette, etc., to be around any vehicle, especially during fuelling operations, when the fuel system is open to the atmosphere, or when servicing the batteries.

1.13

• AFTER transporting (trucking) a machine from one job site to the next, open all doors and access panels and blow off any debris that may have repositioned itself onto the engine and exhaust parts due to wind turbulence caused by the journey.

• Before starting repair work, such as welding, clean the surrounding area and a have a fire extinguisher close by.

• Store rags and other combustible materials in a safe, fireproof location.

• Do not use the machine on top of or to push piles of burning timber. A machine fire will most probably result.

NOTICE Equipment fires adversely effect your ability to log, may increase your insurance premiums dramatically or prevent you from obtaining insurance coverage at all.

Safety

Tigercat Power Clam Grapple

WHAT TO DO TO PREPARE FOR A MACHINE FIRE

• When portable fire extinguishers are provided for use in the workplace, training must be provided to familiarize workers with the general principles of fire extinguisher use and the hazards involved with fire fighting.

• Prevent the fire from happening in the first place by ensuring all machine systems are frequently inspected and always well maintained.

• All hand held fire extinguishers must be charged and in working order. Fire extinguishers require routine care. Follow the manufacturer’s instructions for inspection and maintenance shown on the label of the fire extinguisher and in the FIRE EXTINGUISHER MANUFACTURER'S DOCUMENTATION. • Any pressurized water systems on the machine (if applicable) must be charged and in working order.

• You must have the proper fire extinguishers on site.

Most fires involving mobile forestry equipment will be Class A or B.

• Training must be provided upon initial employment and at least annually thereafter.

• After you have received the training as outlined above, you must know how to use the fire extinguisher, the pressurized water system (if applicable) and the fire suppression system** on your machine. There is not enough time available to read instructions during a fire emergency.

• All information necessary for you to immediately contact all sources of help (local fire department, etc) in the event of a fire emergency must be recorded and readily available at all times.

Dry chemical extinguishers must be rated ABC and pressurized water extinguishers must be rated A.

WHAT TO DO WHEN A MACHINE FIRE OCCURS

Class A fires involve ordinary combustibles such as wood, cloth, paper, rubber and many plastics, Class B fires occur with flammable liquids such as diesel fuel, oil and grease and Class C fires apply to energized electrical equipment.

If operating the machine when a fire occurs:

• Ensure the nozzle of any hand held extinguisher and pressurized water system available on the machine and at the work site fits within the fire extinguisher access holes in the doors of the machine.

• The fire detection system* must be in working order.

Refer to FIRE SUPPRESSION SYSTEM in SECTION 2 of the MACHINE OPERATOR'S MANUAL. • The fire suppression system** must be charged and in working order. Refer to FIRE SUPPRESSION SYSTEM in SECTION 2 of the MACHINE OPERATOR'S MANUAL. • You must be familiar with the recommended procedures for fire contained in the emergency action plan of your company.

1. Lower all working attachments to the ground.

2. Turn OFF the engine.

3. Activate the fire suppression system**.

4. Radio or call for help. Be certain to report a fire immediately.

5. Exit the machine taking fire extinguisher and pressurized water system hose (if applicable) with you.

6. At all times ensure your own personal safety and the safety of anyone that may be in the area. Approach any fire with extreme caution. All fires can be very dangerous and life threatening.

7. Only if you can safely do so, turn OFF the battery disconnect switch.

8. Before deciding to fight the fire, be certain that: • The fire is small and not rapidly spreading.

• There is always a clear, safe escape route to your back.

• You must follow all national, state/provincial and local regulations dealing with fire fighting in effect in your specific geographic region. Regulations will vary from region to region but most will usually require: • Workers assigned to fire fighting duties must be physically capable of performing them safely and effectively.

• Workers designated to use fire fighting equipment as part of an emergency action plan must receive full and proper training from a qualified instructor.

• You have received training in the use of the available fire extinguishing systems and are confident you can operate them effectively.

• If in any doubt about whether or not to fight the fire – do not. Instead stand well clear of the fire and wait for help to arrive.

9. Be aware, hoses containing engine coolant, diesel fuel or hydraulic hoses could fail during a fire. If this happens, hot coolant, fuel or oil could possibly be ignited by the fire.

10. If possible use a dry chemical fire extinguisher or fire suppression system** first to fight a machine fire.

Then immediately afterwards use the pressurized water hose supplied with the machine (if applicable) or a pressurized water extinguisher (if available).

1.14

Tigercat Power Clam Grapple

Safety

A fire suppressed by dry chemical may re-ignite from the heat retained by any debris or hot machine components in the area. The water will cool the area, reducing the chances of re-ignition.

• Use the Pull-Aim-Squeeze-Sweep (PASS) method. This is the most effective use of a fire extinguisher:

WHAT TO DO AFTER A MACHINE FIRE HAS OCCURRED Before returning the machine to work: 1. Ensure the cause of the fire is determined and all appropriate repairs are completed.

• Pull the pin at the top of the extinguisher that keeps the handle from being pressed. Break the plastic seal as the pin is pulled.

• Aim the nozzle at the base of the fire. Do not aim the nozzle at the flames. In order to put out the fire, you must extinguish the fuel, not the flames. Hose nozzles are often clipped to the extinguisher body. Release the hose before taking aim.

• Squeeze the handle to release the pressurized extinguishing agent. The handle can be released at any time to stop the discharge.

• Sweep from side to side at the base of the fire until the fire is completely out or the fire extinguisher is empty.

2. Ensure the fire detection system* or the fire suppression system** is properly serviced and in working order (if applicable).

3. Replace or recharge all extinguishers used in fighting the fire.

• Notify your equipment dealer and/or Tigercat Industries Inc. by completing an incident report, Tigercat form number 5101. *NOTE: Fire detection systems are offered by Tigercat as an optional installation on some Tigercat product lines. Please disregard any references made to fire detection systems if not installed on your machine. **NOTE: Dry chemical fire suppression systems are offered by Tigercat as an optional installation on some Tigercat product lines. Please disregard any references made to fire suppression systems if not installed on your machine.

DRY CHEMICAL CLEANUP PROCEDURES Both ABC dry chemical fire extinguishers and fire suppression systems discharge a chemical powder to extinguish the fire. The chemical makeup and the small particle size of the powder as well as the force of the discharge all contribute to the fire fighting capability.

These same characteristics also permit the powder to penetrate into and fully cover all components in the vicinity of the discharge.

The following are recommendations for the cleanup and neutralizing of areas exposed to dry chemical powder:

700068

NOTE: When performing this work, wear protective clothing, safety goggles, and a fine-particle dust mask to minimize personal exposure to the dry chemical powder.

Typical Fire Extinguisher Access Hole

• Place the nozzle of the fire extinguisher into the appropriate fire extinguisher access hole and discharge the extinguisher.

1. De‑energize all electrical systems completely prior to any cleanup.

• Only if you can safely do so, open the access panels to the machine in the area of the fire.

• Failing all attempts to access the machine compartment, discharge the extinguisher through the mesh or any available openings on the machine.

• Ensure the machine and all components have cooled down sufficiently after a fire to prevent re-ignition from occurring.

2. In areas of the machine that remained cool and dry during the fire, the dry chemical will stay in powder form. Clean these areas immediately to prevent any settled residual powder from coming into contact with moisture whether through direct contact or humidity in the air: a. Remove the powder residue by blowing off with air, sweeping, dusting, or vacuuming using a HEPA filter capable of trapping the small dry chemical particles.

• Remain with the machine until help arrives.

b. Then wipe all surfaces with a damp cloth.

1.15

Safety

Tigercat Power Clam Grapple

3. In areas exposed to moisture, the dry chemical powder will combine with water to form a mildly acidic paste.

NOTE: All surfaces covered by this dry chemical paste including electrical contacts are vulnerable to corrosive attack.

To neutralize the acidic paste on large surfaces: a. Spray or wash these areas with a mixture of 3 parts hot water to 1 part baking soda. b. Allow this mixture to stand for several minutes before washing the area with a solution of warm water and mild soap. c.

Rinse thoroughly with water.

d. Blow-dry to remove all residual water. e. Clean electrical contacts with an electrical contact cleaner that has no flash or fire point and is non-corrosive and non-conductive such as CRC Contact Cleaner 2000.

4. In areas exposed to heat during the fire, the dry chemical powder will melt, forming a coating that cakes or crusts on all surfaces. To clean these areas: a. Break down the caked dry chemical by spraying or washing these areas with a 50/50 mixture of hot water and isopropyl alcohol. Allow this mixture to stand in place for several minutes. b. The caked dry chemical when exposed to moisture is also mildly acidic. Therefore follow immediately with the neutralizing procedure as described in step 3.

Assembly Torque The four-bolt port is simply a circular opening (flow passage) surrounded by four tapped holes in a certain pattern for acceptance of the flange clamping bolts. The flat surface of the port compresses the O-ring contained in the groove in the flange head when the clamp bolts are torqued. In some instances, the groove is in the port and not in the flange head. The bolts, through the clamp halves, clamp down the flange head onto the flat surface of the port compressing and trapping the O-ring in the groove and leaving no gap for it to extrude under pressure. The hydraulic pressure is thus sealed by the compressed O-ring as long as the bolts are tightened enough to maintain solid metal to metal contact between the flange head at the outside diameter of the O-ring and the top of the port.
