Styrene has been a chemical I just can not seem to get away from. I dealt with it throughout my career in the petro-chem industry and now as a consultant, I have a number of clients who use this flammable liquid in a number of different processes. In 2005 I was consulted about a leaking…...

A client has allowed me to share work I did several years ago when OSHA’s GHS threw a wrench into the flammable liquids world! There was so much confusion between Class and Category of flammable liquids, and during an engineering review, it was discovered that the engineering group had made a conversion error when going…...

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…...

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…...

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…...

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…...

SAFTENG NOTE: Please do NOT misunderstand what is being said here. This study was in NO WAY an endorsement that cell phones are safe for hazardous locations. What is being said, is that cell phones do not cause gasoline fueling fires; which we have debunked that myth here for over a decade. Static electricity generated…...
