Fire, explosion and risk assessment
Fire and explosion strategy
(Issue 1) Presents the strategy development carried out by HSE's Energy Division (ED) to address fire and explosion issues on offshore installations. It reviews the current state of knowledge about fire and explosion hazards, their prevention, control and mitigation. It identifies current areas of uncertainty and describes the strategy areas where areas of significant uncertainty require clarification.
Testing regime for offshore TR-HVAC fire tampers and TR pressurisation requirements
(Offshore Information Sheet 1/2006) Guidance for dutyholders on better practice in testing HVAC fire dampers to achieve a reliability and availability approaching 100%. It also provides guidance on the basis for temporary refuge (TR) pressurisation and to advise on the testing requirements to achieve a positive internal pressure for the specified TR endurance time.
Guidance on risk assessment for offshore installations
(Offshore Information Sheet 3/2006) Guidance for asset managers, safety managers and safety engineers in the offshore industry on suitable and sufficient risk assessment, particularly in the context of the Offshore Installations (Safety Case) Regulations 2005
Modelling of pool fires in offshore hazard assessments
(Offshore Information Sheet 9/2008) Guidance on modelling of pool fires hazards on steel decking. Early experimental work has shown that pool fires not contained by a bund are liable to cause severe deck plate buckling and possible weld shear.
Fire and explosion hazards in offshore gas turbines
(Offshore Information Sheet 10/2008) Guidance for dutyholders of offshore installations on identifying fire and explosion hazards in offshore gas turbines. In recent years there has been a marked increase in fires associated with these machines.
Contaminated lagging and self-heating
(Offshore Information Sheet 11/2008) Guidance for dutyholders on oxidative self-heating (OSH) hazards associated with lagging type material contaminated with organic fluids.
Testing of HVAC dampers
(Safety Notice 6/2005) This notice highlights the need for adequate inspection and testing of safety-critical HVAC dampers, at an appropriate frequency, in order to secure confidence in their operation and reliability.
Explosion protected electrical heaters
(Safety Notice 1/2009) In a recent incident on an offshore installation, there was an explosion in an open drains tank containing oily water. The tank contained an electric heater which was Ex certified. However, the sheath on the electric heating element had corroded, exposing the conductor. Although the incident is still being investigated, it is thought that this fault led to ignition of flammable material in the tank. The notice provides guidance on inspecting and maintaining electric heaters.
