Minor Electrical Hazards To Avoid In Laboratories There are several possible and electrical dangers to prevent when one is in a space of experiment work like the laboratory. Standard laboratory operations require staff members to come in contact with various chemicals, substances, and apparatus that are powered by electricity. And this work design creates inevitable risks. Major hazards include the consequences of resistive heating in instruments. A lot of laboratory personnel have from one time and another cited electrical shock and exposure to vapor that are flammable as avoidable situations. With the reality of coming into contact with different electrical instruments whether under controlled and uncontrolled conditions, risks are going to initially be a lot. Examples of apparatus in a laboratory are power supplies, an oven, a hot plate, lasers, and vacuum pumps, stirrers, fluids and even a laboratory battery backup. Since experiments are regularly conducted in laboratories worldwide, standard work practices have been put in place to minimize the risks of major hazards. However, one should not dismiss the potential dangers of the minor hazards resulting from static electricity and electric arcs. It is known for charges that exist even in short duration to be hazardous to both the electrical instrument and the laboratory personnel. This is because it is typical for charges such as arcs to create currents in a spontaneous manner. Additional minor hazard sparks. Minor electrical hazards can include the following: • Static electricity that is affected by a nearby hazardous substance or chemical Static electricity can be a cause for concern when it’s affected by a hazardous material. Such materials can be a gas that’s flammable which can potentially be dangerous in accumulated amount coming in contact with each other. Be mindful of flammable vapor as well. • Occurrence of sparks If you must know, sometimes electricity jumps across a small gap in a circuit. This is how sparks are created. Electrical equipments such as thermostats and drills are known to create sparks. The danger of this reality is that Flammable materials or shock can be definitely be ignited by sparks. • The possibility of electric arcs When a circuit is shorted or when the flow of a current is interrupted, electric arcs are created. These bands of sparks can also result from a switch being closed. They are capable of causing electric shocks. It is also known to cause material combustion. Preventing the occurrence of electric arcs can be done by regularly ensuring that components of circuits are connected before energizing the circuits. Important: Never attempt to close a switch or circuit breaker in a slow manner.
To easily prevent or minimize minor electrical hazards, simply follow the tips cited below: 1) Regularly inspect the insulation on cords and cables for any proof of deterioration. A conductor must be removed if it is exposed. Have the repair be conducted by a professional only. 2) Splicing of cords is not advisable. Never attempt to splice an equipment or use one in such state. 3) Power cords are supposed to be rated for a specific device with which they are to be used. Any anomaly in this aspect should be a cause for concern. More importantly, ensure that connecting cords and cables are fit for the currentâ€™s magnitude to be found in an activity. This is very useful for power failures, especially for the use of a laboratory battery backup. 4) Plugs that are broken should never be used. A plug needs to be complete with a ground prong. Do not attempt to remove the ground prong from a plug. 5) Extension cords are not advisable in a laboratory setting. Such codes are known to overload the circuit which is definitely a hazard. 6) Electrical shorts can be caused by outlets that are loose, so have a professional conduct the necessary repairs when you spot one. Following a guideline in preventing minor electrical hazards can be simple but the effects in a laboratory setting can be for the long-term.
