Workplace Explosions in Pennsylvania

Employers are responsible for providing workers with working conditions that do not pose a risk of serious harm. Sometimes accidents happen because employers do not uphold that responsibility and other times they happen due to unforeseeable circumstances. It is important that both employers and employees be aware of the common causes of workplace explosions, so they can be avoided whenever possible. Occupational Health & Safety (OHS) lists five major causes of workplace explosions:

Combustible dust: Combustible dust is a byproduct of almost all industries including woodworking, manufacturing and pharmaceuticals. Items that do not pose a fire risk when in whole form may be combustible when in dust form. Combustible dust is present in many work environments and includes metal, wood, coal, carbon, organic and plastic dust.

Hot work: Hot work includes activities such as welding, torch cutting, and soldering. Sparks from this type of work can reach temperatures of 1,000 degrees or more and can travel approximately 35 feet. Hot work is often the catalyst for combustible dust explosions because the sparks can ignite dust in the surrounding area.

Flammable liquids and gasses: Flammable liquids and gases are present in many workplaces and include cleaning solvents, paints and crude oil. When they are not stored in accordance with OSHA requirements, it can lead to an industrial fire or explosion. Employers should store flammable liquids and gasses properly, keep them away from ignition sources and provide employees with the appropriate personal protective equipment (PPE).

Equipment and machinery: Improperly maintained or faulty equipment and machinery can cause industrial fires or explosions. Hot work equipment and furnaces are typically responsible for this type of accident; however, an explosion can also occur when machinery has excess grease or not enough lubrication between moving parts. Employers should keep equipment and machinery clean and properly maintained to reduce fire risk.

Electrical hazards: When wiring is exposed or not up to code or outlets are overloaded, an electrical fire can break out. Electrical fires can also ignite combustible dust or flammable liquids and gasses, leading to compounding, catastrophic consequences. Employers should follow OSHA requirements and train employees on how to prevent electrical fires.
