What this inspection record means

OSHA opens inspections for many reasons — routine scheduling under a national or local emphasis program, an employee complaint or referral, or a follow-up after a reported injury. Opening or conducting an inspection is not itself an allegation or a finding that this employer broke any rule; any findings appear as the citations listed below, and citations can be contested, reduced, or withdrawn.

Section 5(a)(1) of the Occupational Safety and Health Act of 1970: The
employer did not
furnish employment and a place of employment which were free from
recognized hazards
that were causing or likely to cause death or serious physical harm to
employees in that
employees were exposed to the recognized hazard of fire and explosion.
Specifically:
On July 08, 1996 at approximately 8:45 PM at the No. 5 Hydrotreater a 10
inch stainless
steel pipe between heat exchangers X-1103 and X-1100 ruptured releasing
hydrocarbons
causing a fire and explosions. The 10 inch pipe failed as a result of
chloride stress corrosion
cracking and metal fatigue which was caused by the piping not being
properly passivated
during startup activities. Among other methods, one feasible and
acceptable abatement
method to correct this hazard is to passivate all austenitic stainless
steel piping in the No. 5
Hydrotreater using a mixture of soda ash and sodium nitrate. Also, develop
and implement a
program for periodic inspections using the proper testing to detect
chloride stress corrosion
cracking in the No. 5 Hydrotreater and all similar units.
