Propane-Powered Floor Buffers Expose Workers to Carbon Monoxide

Workers who use propane-powered floor burnishers to polish floors frequently are exposed to dangerous levels of carbon monoxide, a colorless, odorless, and poisonous gas. Exposure to carbon monoxide can cause nausea, headaches, weakness, and dizziness; extended exposure may result in loss of consciousness or death.

To Avoid the Risk of Worker Exposure to Carbon Monoxide Poisoning:

• A recent study found that propane-powered buffers fitted with emissions controls can reduce maximum worker exposure to carbon monoxide by 91 percent.

• These controls include a self-aspirating catalytic muffler and computerized monitors and alarms which detect and burn incompletely combusted fuel, which contains carbon monoxide, emitted by the engine.

• Be aware that controls must be properly fitted and maintained--blocked air filters, alarm failures, and other mechanical malfunctions with controls may lead to excessive carbon monoxide emissions.

• The single best way to eliminate entirely the risk of carbon monoxide exposure is for employers to use electric-powered floor burnishers.
