Controlling Fire Hazards in Metalworking Facilities: Flammable and Combustible Liquids

Fire ExtinguisherMetalworking facilities face a number of fire hazards, including:

• Wiring and electricity

• Heating

• Flammable and combustible liquids, aerosols and liquid petroleum

By being diligent in preventing employee and customer injuries, as well as property damage, you will help minimize accidents and help to reduce your insurance costs.

You can help control and manage the insurance risks associated with fire hazards by implementing these tips:

Flammable and Combustible Liquids, Aerosols and Liquefied Petroleum (LP)

• Substitute less flammable/volatile products whenever possible

• Isolate large quantities from production areas

• Use non-flammable cleaning medium in parts washers

• Use a free-closing lid with a tight seal on parts washers containing petroleum-based solvents

• When using or storing flammable liquids:

– Limit work area quantities to a one-day supply

– Use only UL-listed or FM-approved safety cans at the point-of-use

– Provide adequate general and local ventilation

– Eliminate ignition sources

– Train employees on proper grounding and bonding procedures

• Keep in mind that aerosols can be more volatile than flammable liquids because of the explosive nature of container ruptures

• Locate bulk storage tanks outside of buildings and enclose with fencing and substantial barriers, such as reinforced concrete or steel posts when storing liquefied petroleum (propane or butane)

• Keep chemical compatibility in mind as part of your effort to inventory and store chemicals
