Summary
An explosion at the Partridge-Raleigh oilfield in Raleigh, Mississippi. The incident occurred at about 8:30 a.m. on June 5, 2006, when Stringer’s Oilfield Services contract workers were installing pipe from two production tanks to a third. Welding sparks ignited flammable vapor escaping from an open-ended pipe about four feet from the contractors’ welding activity on tank 4. The explosion killed three workers who were standing on top of tanks 3 and 4. A fourth worker was seriously injured.
KEY ISSUES:
• HOT WORK CONTROL
• SAFE WORK PRACTICES AT OIL & GAS PRODUCTION WELLS
ROOT CAUSES:
1. A gas detector was not used to test for flammable vapor.
2. ‘Flashing’ tanks containing hydrocarbons with a lit oxy-acetylene torch to determine the presence of flammable vapor is unsafe and extremely dangerous.
3. The open pipe on the adjacent tank was not capped or otherwise isolated.
4. A makeshift work platform – a ladder placed between the tanks – was used.
5. All tanks were interconnected and some of the tanks contained flammable residue and crude oil.
