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broke any rule; any findings appear as the citations listed below, and citations can be contested, reduced, or withdrawn.

5(a)(1)

Serious Gravity 10 2 instances 20 exposed
Issued
Jul 11, 2008
Abate by
Jul 15, 2008
Penalty
Initial $7,000 · Current $4,200 Reduced
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:
Drilling floor; on or about March 27, 2008, employees engaged in the
drilling of an oil/gas well
with a drilling rig used the break out tong during pipe connections and
tripping out of the well
(removal of the drill pipe string); the wire rope connecting the tong to
draw works was severely
damaged and had an knot for attachment.  This exposed the employees to the
hazard of being
struck by an uncontrolled tong assembly upon failure of the wire rope.
Among other methods,
feasible and acceptable abatement methods to correct this hazard would be
to conduct wire rope
inspections and removal criteria as recommended by American Petroleum
Institute (API)
Recommended Practice (RP) 54, Section 9.6; and remove damaged wire ropes
from service as
mandated by RP 54 Section 9.6.6.  Additionally, RP 54, Section 9.9.5,
assure that fittings to
attach the back up lines have a minimum breaking strength at least equal
to that of the wire rope.
