Why this sign: It should be posted wherever flammable gases, liquids, or vapours may be present and where an open flame could trigger a fire or explosion. Typical locations include LPG storage areas, fuel depots, and any workspace handling highly flammable substances. The sign serves as a clear, standardised warning to workers and visitors that ignition sources must not be introduced into the area.

Compliance note: In Ireland, employers must provide appropriate safety signage where hazards cannot be avoided or adequately reduced by other measures, based on the workplace risk assessment, under the Safety, Health and Welfare at Work (General Application) Regulations 2007. This sign is suitable for use as part of a workplace safety-signage system where identified by that risk assessment.
