The Department of Labor’s Occupational Safety and Health Administration has released a list of the 10 most frequently cited safety and health violations for the fiscal year of 2017; compiled from thousands of inspections of workplaces by federal OSHA staff. One remarkable thing about the list is that it rarely changes. Year after year, thousands of the same on-the-job hazards are cited, any one of which could result in a fatality or severe injury.
HFO-1234yf REFRIGERANT IS A FLAMMABLE GAS
Automobiles have been using refrigerant gases in their AC systems for decades. The refrigerant gases have generally been inert gases, such as Freon-12 and R-134. Recently, many auto manufacturers have started to use HFO-1234yf as the refrigerant gas in their AC systems. This gas is expensive, about $80/lb., and the recycling machine costs another $5000. The bigger issue is that it is a flammable gas. Flammable gases pose special hazards and dealers should take steps to address this concern.
