On Jan. 19, 2016, the Hartford Area Office cited a chemical manufacturer for 15 serious violations of workplace safety standards. Inspectors found that a manufacturer of swimming pool chemicals and acetone preparations used in nail polish were exposed employees to chemical, fire and exit access hazards. The company’s manufacturing processes use large amounts of the flammable chemicals acetone and isopropyl alcohol 99 percent. OSHA standards require a workplace to have a program for safely managing processes involving large amounts of these chemicals. The plant lacked a process safety management program. Deficiencies included:

At the site of an inactive gas well, two workers were flowing the high-pressure gas from the well to determine production potential. They were inside an operator's shack when a pipe ruptured, and the escaping flammable gas exploded in a fireball. Although the two workers were wearing fire-retardant clothing, they suffered burns. The smaller piping downstream from a pressure relief valve (PRV) was one of the factors that caused the piping system to fail.

We continue to see the “check the box” engineering when it comes to “ventilation” requirements for processes that fall under PSM/RMP. I have written about the design basis and the many flaws we come across regarding the actual design, but this one is becoming more and more prevalent. I am thinking “space” is becoming less available so facilities are installing their FRESH AIR INTAKES in the darnedest places.  In this article I home to educate those interested in the most basic need for a FRESH AIR INTAKE and that is…. FRESH AIR.

This week I participated in an on-line discussion regarding a new "telltale indicator" that is being used in refrigeration processes. A really neat device that will indicate when a RV has lifted; however, I questioned it’s design and whether or not it could be considered an “obstruction” in the RV vent line. This device has a “paddle” type device that swings when moved by the pressure flowing through the device. The paddle is hinged on a bar that passes through the vent space.
