Flammable Liquids OSHA 1910.106 Don’t get burned by what you can’t see. Flammable liquids can be found in almost every area of the work place. Invisible vapors released from these volatile liquids are what create fire & explosion hazards. Even in small amounts, these liquids can create an ignitable atmosphere with the right vapor and air mixture. Flammable Liquids Sources of Ignition Gasoline Kerosene Solvents Strippers Alcohol Benzene Open Flames Smoking Static Electricity Cutting & Welding Hot Surfaces Lightning Electrical & Mechanical Sparks Flammable Liquids, Flash Points and Volatility Simply put, liquids are rated as flammable because the vapors they give off can catch fire. Flash point refers to the temperature in which a liquid will form an ignitable mixture in the air. Volatility refers to liquids with a high vapor pressure they evaporate quickly. Transferring/Dispensing When flammable liquids travel through a pipe or through the air, static charges are accumulated. Grounding and bonding is necessary during the transfer of flammable liquids that have a flashpoint below 100º F to prevent a static spark from igniting the flammable vapors. An example of grounding and bonding is illustrated in the photograph below. SAFETY
