How these injuries happen

Flash fires are the primary cause of injury, accounting for 57% of all reported incidents involving flammable gases. These events occur when leaking vapors encounter an ignition source, such as a torch, pilot light, or electrical spark. You are often caught in sudden, intense heat when gas accumulates in confined spaces or escapes during the transfer of fuel between cylinders.

Real cases like yours

Common patterns in these incidents involve the failure to properly manage residual fumes during equipment repair or the accidental release of gas during fuel transfers. You are often injured while performing routine maintenance on tanks or using torches near pressurized lines. If any of these scenarios sound like what happened to you, an attorney can help you review the specifics of your incident to determine if employer negligence played a role.
