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employer broke any rule; any findings appear as the citations listed below, and citations can be contested, reduced, or withdrawn.

Penalty
Initial $6,300 · Current $6,300
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:
Refinery boiler house; on or about April 30, 2007, employee(s) was exposed
to the hazards
resulting from a boiler combustion chamber explosion, which could subject
employee(s) to being
struck by a pressure wave, moving boiler structure, flying debris, and
high heat.  The
employee(s) operated and maintained refinery utility steam boilers.
Boilers #4 and #5 were not
equipped to detect boiler flameouts with an automatic shutoff of fuel to
the boilers; additionally
the induced draft air control system was inoperative.
Among other methods, one feasible and acceptable means to correct this
hazard is the installation
of combustion management system incorporating flame detection coupled with
automated safety
fuel shutoff valves activated by the loss of burner flame; and by assuring
all
boiler systems are
maintained in an operative condition.
