Plastic Pumps Installed to Pump Flammable Liquids

With all of these benefits, it was easy for maintenance engineers to consider these pumps for many applications. Some plastic diaphragm pumps were mistakenly installed to transfer flammable liquids in several units of a chemical complex. [Pg.187]

These polytetrafulorothylene (PTFE) pumps along with the associated plastic expansion joints were installed, because the sponsors were blinded by the advantages. No one took the time to question their suitability in handling flammable liquids. The plastic pumps are just not fire-safe. They are frail in a fierce hydrocarbon fire. The presence of a containment material, such as plastic, can jeopardize the built-in mechanical integrity of the surrounding equipment. [Pg.187]

Weak Walts Wanted- But Alternate Attaciments Contributed to the Darhage [Pg.152]

Compressors handling flammable gases have the potential to leak. Ideally such compressors should be installed outdoors so that leaks can disperse. At times, compressors are designed to operate within buildings, such as ones in very cold climates. [Pg.152]

In one repf3rted case, a construction manager reviewed the drawings of a gas compres sor building before construction. He observed that very weak clips were specified to secure the plastic sheets to the structure. He apparently did not understand the concept, becau.se he decided they were too weak and replaced the specified clips with more robust dips. [Pg.152]
