SECTION 5.0 EQUIPMENT, MATERIAL AND OBSERVATIONS
5.1 Equipment and Material
5.1.1 The Pipe-Matic 3000XT is a powered catwalk that is used to move tubulars (i.e.
drilling pipe) between the pipe rack area and the drilling floor. The equipment
consists of a catwalk on a sub-frame with two pipe elevators (approximately 4500 lbs.
each), one on either side of the catwalk, on four sets of wheels. The Pipe-Matic
3000XT is manufactured by Canrig Drilling Technology Limited.
5.2 Observations
5.2.1 Officers arrived on site at approximately 5:40 p.m. and a brief meeting was held with
the company representatives to discuss the events of the incident. The incident scene
on drilling pad #101 was secured by the RCMP and was still under the RCMP’s
jurisdiction. A discussion was held with the RCMP officers on site and at 6:20 p.m.
the incident scene was turned over to Occupational Health and Safety.
5.2.2 The scene contained the catwalk with the two pipe elevators removed and laying on
the ground. The North side elevator was on the ground with no equipment attached to
it. The South elevator was attached to a loader with chain; the arms of the loader
were in the down position.

SECTION 6.0 NARRATIVE DESCRIPTION OF THE INCIDENT
6.1 On the morning of October 18, 2012 Nabors Drilling was in the process of rigging
down (dismantling) drilling rig #103. At approximately 9:30 a.m. the Pipe-Matic
3000 XT was removed from the drilling rig and moved to the location where the
incident occurred.
6.2 After lunch the Floor Hand and the Motor Man were assigned the work of rigging
down the Pipe-Matic 3000XT by the Rig Manager. The Motor Man was driving a
loader, with a grappling fork attached, completing other jobs while the Floor Hand
was removing the four bolts from each of the two pipe elevators
6.3 At approximately 1:30 p.m. the Motor Man drove his loader to the pipe elevator on
the North side of the Pipe-Matic 3000 XT and placed the forks at the top of the pipe
elevator to support it for removal.
6.4 The Motor Man noticed that the hydraulic lines were still connected to both pipe
elevators and instructed the Floor Hand to disconnect the hydraulic line on the South
side and that he would disconnect the line on the North side.
6.5 The Motor Man climbed on the inside of the pipe elevator to disconnect the hydraulic
line on the North elevator. The Labourer witnessed the Floor Hand working under the
Pipe-Matic 3000XT. When the Floor Hand came out from under the Pipe-Matic
3000XT, to the East, he hit or struck the pipe elevator with either his gloved hand or
with gloves in his hand and proceeded to walk in front of the pipe elevator in a South
West direction.
6.6 While the Motor Man was getting back into the loader, he heard a loud bang when the
South elevator fell.
6.7 The Labourer yelled at the Floor Hand to get out of there but the Floor Hand was only
able to take one step before being struck by the pipe elevator causing fatal injuries.
6.8 The Motor Man ran around the Pipe-Matic 3000 XT where he saw the Floor Hand
pinned under the South pipe elevator and went to get the Rig Manager
6.9 The pipe elevator was lifted off of the Floor Hand by the Loader Operator with the
use of another loader and chain.
6.10 The Floor Hand was pulled from underneath the pipe elevator and medical assistance
was initiated by the medic and workers on site. The Floor Hand was pronounced
dead on the way to a hospital.

SECTION 7.0 ANALYSIS
7.1 Direct Cause
7.1.1 The cause of the incident is the pipe elevator falling and striking the Floor Hand
causing fatal injuries.
7.2 Contributing Factors
7.2.1 Through the investigation there was no evidence that the Floor Hand had completed
the task of rigging down (dismantling) the Pipe-Matic 3000XT before. As well there
is no evidence that the Floor Hand had received proper training for the task and was
not under the direct supervision of a competent worker.
7.2.2 Most training that is completed by employees is done mostly by job shadowing other
individuals. Once an individual has been deemed competent by an individual it is
reported to the Rig Manager. There is no process in place that the Rig Manager uses
to confirm the competency of individuals. At the time of the incident there were no
documents available to determine when a worker was deemed competent.
7.2.3 The pipe elevators were no longer secured to the catwalk once the eight bolts (four
per side) were removed, leaving the pipe elevators balancing on a ledge on the side of
the catwalk.
