Question
(a) A gas scrubber on an oilrig discharged gas periodically such that an accumulation of hydrocarbon gas nearby had occurred. A contractor welder was dispatched to a job immediately adjacent to the area and it being a shift change and personnel unavailable temporarily, the welder decided to commence welding. As a consequence, an incident occurred. Describe briefly: (i) what you imagine was the incident including any hazards existing prior to or during the incident (ii) the consequences of the incident on personnel, equipment or process (iii) emergency procedures put into practice during and immediately after the incident (iv) indications of possible cause(s) of the incident (include any breaches of safety procedures (permits to work, etc.) statutory systems, codes of practice and company safety rules that led to the incident and any other causes or contributing circumstances (v) recommendations/suggestions that would reduce the possibility of a repetition of the incident. (This is based on a real incident.)
Explanation / Answer
1) Since its a Welding operation, The ignition will start as a chain reaction causing hydrocarbons released from various Storage Tanks and leading those too subsequently ignite starting a fire on the platform.
2) > Immediate death of Welding workers, Problem to comply or involve new welding Requirements.
> Equipment loss, depending on the number of stored Hydrocarbons Storage Tanks
3) > Calm down the flames and immediate rescue of the remaining workers. Since its a chain Reaction, their are more chances of Leakage and higher rate of explosion
> Immediate action on the oil rig for the destruction and leakage of harmful hydrocarbon
4) "stop work" event will be involved despite apparent anomalies
5) A welding supervisor with outlined in 30 CFR 250.111 i.e Article on safety precious for various factories. Operators should require all operations and contract on personnel involved in hot work,
various educational meeting to be involved explaining varies contingencies, regulations, policies.
"Black Elk energy" safety needs to be involved
