Confined space fatality

Two cylindrical foam sponge pads had been inserted in a riser guide tube to form a plug. Argon gas had been pumped into the 60 cm space between the two sponges as shielding gas for welding on the exterior of the riser guide tube. After completion of the welding, a worker descended into the riser guide tube by rope access to remove the upper sponge. While inside, communication with the worker ceased. A confined space attendant entered the riser guide tube to investigate. Finding his colleague unconscious, he called for rescue and then he too lost consciousness. On being brought to the surface, the first worker received CPR; was taken to hospital; but died of suspected cardio-respiratory failure after 2 hours of descent into the space. The co-worker recovered.

Fatigue and an incident

A worker on a pipe laying barge suffered a blackout without warning and fell. The worker had no previous medical condition and had passed a pre-employment medical the day before the event. He was medivaced for treatment of cuts and bruises and underwent further extensive medical examination. The examination did not find any medical condition that could explain the blackout.
The worker had been working for at least 22 hours, including travelling. After arrival on the facility and induction he went straight into night shift. He suffered the blackout in the first shift. Had he been operating heavy equipment or machinery, the consequence of the blackout could have been far more significant.
A significant contributing factor for the above case is fatigue. The effects of fatigue vary from individual to individual. They can include impaired decision making, delayed response time, inability to concentrate, reduced alertness, and blackout. In the cases above, the site management team failed to manage the risk associated with fatigue. There was a perceived need to carry on with the job.
Key Lessons
Recognise fatigue as a serious safety risk that requires appropriate risk management. Fatigue can cause impaired decision marking, delayed response time, inability to concentrate, and reduced alertness.
Set a clear policy relating to hours of work and communicate it to management and employees. Include travel time as working hours.

Floating roof drain incident

In a hydrocarbon storage tank, the floating roof drain valve was kept open during rainy season. One night, operators smelt hydrocarbon vapours in the dyke area and found hydrocarbon liquid coming out of the open floating roof drain. The connection of the floating roof drain to the roof had failed due to corrosion. Are you checking them for internal corrosion?

Hazardous Energy source kills engineer

An analyser engineer was killed when the engineer removed the cover on an explosion-
proof  enclosure during preventive maintenance. As the engineer loosened the cover, it came out with force and hit him on the head. The force was caused by pressure inside the enclosure from leaking sample gas or instrument air components. It was not equipped with an external indicator to determine the pressure inside the enclosure nor did it have any pressure relief device.
When you hand over equipment for maintenance, make sure all sources of energy are locked out, tagged out and tried.
