The DSEAR (Dangerous substances and explosive atmospheres regulations 2002) and Statutory instrument 1996 No.192 (The Equipment and Protective Systems Intended for Use in Potentially Explosive Atmospheres Regulations 1996) are applicable to all UK industrial sites with inventories above 50 litres of highly flammable or extremely flammable fluids or above 250 litres of flammable fluids. They are also applicable to companies storing or using explosible dusts or powders.
One of the obligations of DSEAR is to classify places where potentially explosive atmospheres may occur, into zones 0, 1, and 2 for gases and vapours and zones 20, 21 and 22 for combustible dusts. These classifications must then be maintained to take account of changes to plant, materials or operating procedures.
Hazardous area classification can be a complicated and time consuming subject to master, and most industrial sites only need to spend a few days a year on the development or maintenance of area classification. This means that using an external consultant for area classification is very cost effective.
Ex Experience Ltd. can provide the expertise and experience that will produce a Preliminary hazardous area classification at an early project stage, which can then be updated to ‘as built’ when the project approaches completion and enters the commissioning stage. Alternatively we can update an existing area classification using current published guidance or produce a new hazardous area classification for an existing plant. This can be done within a practical pre-arranged time-frame and for a realistic price.
The classification cannot take place without input from your own engineers and operators but Ex Experience Ltd. will co-ordinate the information gathering and the area classification meetings. From this a detailed area classification report will be produced and hazardous area classification drawings will be produced or updated. The classification report and drawings will then be approved and signed off by all of those who took part.
Whatever your hazardous area classification need, we will be happy to evaluate the project and give you an itemised quotation.
It is the path of least resistance for a consultant to describe large hazardous areas, and exercise caution by exaggerating the size and severity of the zones, this means that the consultant is unlikely to be challenged in the event of an incident or HSE intervention, and it might even mean more work for the consultant if they are then selling Ex rated equipment or subsequent hazardous area services to the client. It goes without saying that this approach is not necessarily in the best interests of the client company. Ex Experience Ltd. will not be selling you Ex rated equipment and we take an extremely pragmatic approach to the art of hazardous area classification. Any area classification produced by us, will be based upon published guidance, including appropriate safety factors, but where the guidance from a code of practice is not appropriate to the actual source of hazard being considered, we will use calculations, measurements, team meetings and discussions and lots and lots of pragmatic common sense to ensure that the hazardous areas that we describe are sensible, and appropriate to the source of hazard in question.
