Flammable Liquids

Flammable Liquids per Control Area

One part of managing flammable liquids is minimizing fuel load in the event there is a fire.  Both state codes and OSHA utilize what is called “maximum allowable quantity per control area“.  This practice is based on the “degree of hazard” or as OSHA calls them today “Hazard Category” of the flammable liquid or gas…...

Why smoking while filling up is NOT a wise choice!

I do not know much about this video, such as where it was shot, was it a set up for demo or real-life.  But the FLIR footage is quite telling as we can see the vapors exiting the fill port.  These days in the USA a lot of stations have a “vapor-recovery” system so I…...

What is an approved self-closing valve?

This week I posted the requirement for transferring a flammable liquid using “gravity”.  This requirement comes from OSHA’s flammable liquid standard… 1910.106(e)(2)(iv)(d) flammable liquids shall be drawn from or transferred into vessels, containers, or portable tanks within a building only through a closed piping system, from safety cans, by means of a device drawing through…...

Transferring flammable liquids without a deadman valve can be deadly indeed!

There is a sound reason why OSHA’s Flammable Liquid Standard has required a deadman valve for over 40 years and it is the same reason why I have written about their use for 20 years… When things go bad and you need to get the heck out of dodge quickly, you can do so AND…...

Technical Tip Tuesday… Nitrogen is NOT heavier than air – its actually slightly lighter!

Technical Tip Tuesday… nitrogen is NOT heavier than air! In fact, pure Nitrogen gas is LIGHTER (~3% lighter) than the Oxygen and Argon (with the Nitrogen) that make up our atmosphere. It is perfectly mixed in the air. Hence the air we are breathing right now (assuming you’re on the surface of the earth) is 78%…...
