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.

Serious Gravity 10 2 instances 35 exposed

Abate by
Jun 25, 1993
Penalty
Initial $4,500 · Current $1,000 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 to employees in that employees were
exposed to asphyxiation from the hazard of oxygen deficiency and toxic
during confined space entry:
(a)  On 3/19/93, two employees performed welding inside of
pipes with diameters of 37 1/2" at rotator #7 and rotator
#9.  The employees were inside of the pipes for the majority
of the nine hour shift.  An exhaust ventilation system was
being used at rotator #9 for the entire shift, and at
rotator #7 for a portion of the shift.  both employees
exposures to welding fume were in excess of mg/m3,
recognized by the employer as the exposure limit for welding
fume as evidenced by the reports generated by CNA for
Thompson Pipe and Steel Company.  One employee was
overexposed to iron oxide and total particulate.  This
process in performed on a daily basis, during each of three
shifts.  The employer had not developed or implemented a
confined space entry program which included:
1.  A confined space entry permit system;
2.  Training methods to alert affected employees to the
hazards associated with entering a confined space, and the
methods that employees could use to minimize these hazards;
3.  Procedures for atmospheric testing for oxygen
deficiency, flammable gas, and toxic air contaminants prior
to entering the confined space;
4.  Use of mechanical ventilation to purge the confined
space of dangerous atmospheric contaminants and to maintain
a supply of fresh air; and
5.  An emergency response rescue program.
A feasible and acceptable method to abate these hazards is
to develop and implement a confined space entry program
consistent with 29 CFR
