5(a)(1)

Serious Gravity 10 1 instance 2 exposed
Issued
Abate by
Penalty
Initial $5000.00 · Current $5000.00
Section 5(a)(1) of the Occupational Safety and Health Act of 1970:  The
employer does not
furnish employment and a place of employment which are free from
recognized hazards that are
causing or likely to cause death or serious physical harm to employees in
that employees are
exposed to the hazard associated with striking the landing area at
excessive speed:
Employees working at the derrick platform are exposed to a hazard due to
the
improper installation of the Geronimo emergency escape device.  This
condition
was last documented on August 31, 2006, on Drilling Rig No. 50 at the
derrick
platform above the rig floor, in that:
a.the wire rope used for the Geronimo emergency escape device is installed
with less than the recommended number of clamps (fist grips) at the
anchor;
b.the installed escape line is less than the recommended length;
c.the safety buggy is mounted outside the platform's guardrails.  There is
no adequate means for the employees to safely mount the device before
leaving the work platform.  An employee trying to mount the device
would be exposed to a fall of approximately 90 feet to the rig floor or 122
feet to the ground.
Among other methods of abatement, one feasible and acceptable abatement
method to
correct this hazard would be installation of a properly rigged and secured
emergency
descent device in accordance with manufacturer's recommendations and the
API
Recommended Practice 54, Third Edition, August 1999, Section #6-10.
