A small release can become serious if it reaches the right concentration and meets an ignition source.\u003c\/p\u003e\u003cp\u003eThe weak point is often not the absence of a risk assessment but the quality of the decisions behind it. This IIRSM-approved course gives duty holders a structured framework for identifying dangerous substances, evaluating release and ignition scenarios, selecting suitable controls, and recognising when specialist input is needed. Approximately two hours of fully online training with same-day digital certification.\u003c\/p\u003e\u003ch3\u003eWho is this course for?\u003c\/h3\u003e\u003cp\u003eAnyone with legal or operational responsibility for managing flammable gas and vapour explosion risk under DSEAR, particularly where solvent handling, gas storage, flammable liquid transfer and hazardous area classification create significant compliance responsibilities:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSite managers and operations managers\u003c\/li\u003e\n\u003cli\u003eHealth and safety managers and advisers\u003c\/li\u003e\n\u003cli\u003eCompliance officers and EHS leads\u003c\/li\u003e\n\u003cli\u003eFacilities engineers and maintenance managers\u003c\/li\u003e\n\u003cli\u003eProcess and production managers\u003c\/li\u003e\n\u003cli\u003eDSEAR duty holders and responsible persons\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCourse content\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eModule 1 — Introduction to DSEAR\u003c\/strong\u003e\u003cbr\u003eWhat DSEAR requires and how it fits within the wider UK framework for managing fire and explosion risk from flammable gases and vapour released from flammable liquids.
