Yes, OSHA has rules for the use of flammable liquids in areas that are not designed as a Hazardous Location. OSHA covers Hazardous Locations in 1910.307, but those areas that do not rise to the level of being a Hazardous Location fall under 1910.334(d) which states:… Membership Required You must be a member to access...
This is an excellent photo that shows what happens when a FLAMMABLE LIQUIDS ATMOPSHERIC STORAGE tank does not have proper or adequate emergency venting. As we can see in this photo (Source: AP) the tank is still in tank, but with a large hole (e.g. new vent!). This tank was estimated to have reached the…...

OSHA, as well as NFPA and IFC, permit a “weak roof-to-shell seam” as the means for emergency venting on an OUTSIDE ABOVE GROUND ATMOSPHERIC storage tank for flammable liquids. This method was vey common in the early days, but has since been replaced with engineered fire vents. This video does an excellent job demonstrating how…...
Over the past year or so we have come across several situations where facilities have replaced their flammable liquid storage tanks, which some are used as a “waste tank”. These “waste tanks” fall under EPA’s RCRA rule and apparently these tanks have to be “fully inspected” on a set frequency and when tanks sit directly…...
In the world of process safety, we have Safe Upper and Lower limits on a lot of common process parameters, such as pressures, levels, temperatures, etc. Flows on the other hand are quite often overlooked as a critical process parameter and when your HHC/EHS is a non-conductive flammable liquid both FLOW and LEVEL must be…...

Liquified Petroleum Gas (LPG) cylinders are being filled by decanting equipment. These cylinders can be for commercial use (e.g. forklift trucks) or for domestic use (e.g. cook tops, barbecues, and camping). It is critical that all decanting operations are carried out in a suitable and safe manner. What happened? A fire broke out at a…...
