Chemical Hygiene Plan and Safety Manual - LP3006.6

Section VI: Emergency and Accident Plan

1.0 Outline

In the event of an emergency, the laboratory will have specific handling procedures in place

2.0 Chemical Spills

2.1 General Spills:

2.1.1 If a spill is significant i.e. greater than 100 mL, caution must be exercised and other personnel should be alerted prior to containment.

2.1.2 If a spill includes broken lab ware, proper PPE must be worn to prevent cuts and scrapes. Broken glassware should be disposed of in the glass disposal box.

2.1.3 If a chemical spill occurs that cannot be handled by laboratory personnel, notify all personnel and begin evacuation procedures outlined in section 4.0 below.

2.2 Concentrated Acids and Bases:

2 2 1 In the event of a spill, remain calm and assess the area If the spill is less than 100 mL, don the proper PPE (including acid/base resistant gloves) and clean spill using spillcontainment kit located nearest to spill area

2 2 2 To contain a minor spill:

Make a circle around the spill using the PIG Sock If necessary, more than one PIG Sock can be used

Next, pour the appropriate neutralizing solution on the spill and wait for the color change

Once the solution is neutral, use a PIG Haz-Mat pad to soak up the liquid

Dispose of pad in chemical waste if toxic or appropriate garbage receptacle

2 2 3 For minor base spills:

Use the acidic pink solution. It has a pH of 2.

Once poured on a basic spill, it will turn blue while it’s neutralizing.

Once the solution is completely neutral, the pH will be between 7-9. The solution will be yellow.

Once the solution turns yellow, it’s safe to clean up.

2.2.4 If a spilled acid or base contacts clothes or skin, immediately remove the affected garments and rinse area with sufficient quantities of water.
