Workers were tasked with installing snare wires (a short length of wire used to temporarily secure or "snare" a cable, conductor, or guy wire during installation, maintenance, or repair work). As the utility worker completed their task they proceeded to climb down the pole. As the utility worker stepped down, their right foot kicked out (gaffed out) and they slid down the pole approximately 50 feet to the ground.

The crew was in the process of pushing liner to bottom. After completing the first connection of heavy weight drill pipe, the Floor Hand was moving the ST-80 (iron roughneck) back to its parked position. While maneuvering the ST-80, the extend/retract hydraulic duplex cylinder suddenly failed, causing the unit to fall forward and downward.

Dropped Electrical Phase | Issue 03-2025
While completing annual preventative maintenance on a de-energized vertically mounted overhead isolation switch, an Electrician attempted to close the switch when one phase broke free and fell approximately 14ft. The load side of the switch was connected by cabling, resulting in the broken phase swinging into a nearby switchgear cabinet.

H2S Knockdown | Issue 02-2025
A wireline crew swabbed a sour well with a hydrogen sulphide (H2S) concentration of approximately 10 per cent. During the operation, the crew needed to remove the lubricator assembly to perform routine maintenance. When moving the lubricator back to the wellhead for reconnection, a wireline operator without a supplied-air breathing apparatus lost consciousness and fell down the stairs on the wellhead platform.

Dozer Contacts Light Vehicle | Issue 04-2024
A light vehicle (LV) entered an active work area where a dozer was back blading in a narrow corridor. The LV operator called the dozer operator via radio but received no response, however continued to approach. The dozer reversed, causing major damage to the LV. The LV operator successfully exited the LV and signaled the dozer operator to stop. There were no injuries.

Catastrophic Centrifuge Failure | Issue 03-2024
The workers were processing slurry from a storage tank that was used to store shaker screen runoff. A vac truck was used to direct feed the centrifuge through the centrifuge feed pump. As the second load was finished, the centrifuge operator went to the PLC controls to wind down the machine from its operating speed. At this point, the centrifuge made a loud noise and began to vibrate.
