The Dangerous Substances and Explosive Atmospheres Regulations 2002 apply across multiple railway-sector contexts: traction battery rooms in stations, fuel storage at depots, dielectric fluid in traction substation transformer halls, oxy-acetylene and other compressed-gas cylinders in maintenance facilities, dust-explosion hazards in some maintenance environments, and any standby-power diesel installation.
JWCS delivers DSEAR Risk Assessments scoped per substance rather than the catch-all asset-wide approach that often misses substance-specific control gaps. Hazardous Area Classification (where applicable under BS EN 60079-10 series) is delivered as a drawing-based output with the zone schedule traceable to the source data.
The DSEAR assessment is integrated with the asset’s Fire Risk Assessment under RRO 2005, so the two duties are discharged coherently and the substance-specific control measures land in the unified action plan.
