Flammable Liquid Warning Sign – ISO 7010 Pictogram HS0071

Flammable Liquid Warning Sign – HS0071

This flammable liquid warning sign is the standard ISO 7010 pictogram for Flammable Liquid, showing a black flame symbol on a yellow warning triangle to alert crew that flammable vapours or liquids are present in the immediate area. It is designed to be understood instantly, without relying on written language, so that anyone on board — from a new deck cadet to a visiting surveyor — recognises the danger and adjusts their behaviour before a spark, open flame, or hot surface can trigger an ignition. As a warning-class pictogram it does not prohibit entry outright; instead it tells personnel to proceed with caution, remove ignition sources, and follow the vessel’s permit-to-work procedures for the space.

Catalogued as SKU HS0071 within our Hazard Signs range, this flammable liquid warning sign is one of the most frequently ordered items in the category because flammable liquids are handled or stored on almost every type of vessel. Typical shipboard locations include fuel bunkering stations, paint lockers, chemical stores, engine room fuel transfer points, tank tops near service tanks, and hazardous cargo holds. Wherever a flammable liquid is loaded, stored, or transferred, this sign should be fitted at the point of entry so the hazard is flagged before anyone steps inside.

Every flammable liquid warning sign we supply is produced on rigid, marine-grade material or as a self-adhesive vinyl, depending on the mounting surface, with a photoluminescent option available for spaces where lighting may fail during an emergency. The substrate is formulated to resist saltwater spray, humidity, and UV exposure, so the pictogram stays legible after years of service in exposed or corrosive shipboard environments without fading, cracking, or delaminating.

Why Flammable Liquid Hazards Matter

Flammable liquids release vapours that can travel along a deck or settle in a confined space, reaching an ignition source well away from the liquid itself. Without clear signage, crew, contractors, and visitors may not realise a compartment holds flammable stock until it is too late to take precautions, and a single unmarked spark source can turn a routine task into a fire. A missing or faded flammable liquid warning sign is one of the more common gaps flagged during safety rounds, because inspectors check that hazard areas match the vessel’s hazard register. Keeping this signage in place supports safe permit-to-work decisions and gives crew a fast visual cue during routine rounds.

Compliance and Certification

HS0071 reproduces the pictogram exactly as registered under ISO 7010, the international standard for graphical safety signs, ensuring the symbol is recognised consistently across international crews and flag states. IMO guidance on shipboard safety signs calls for hazard pictograms wherever a flammable liquid hazard exists, supporting the general safety obligations under SOLAS. Port State Control inspectors and classification society surveyors routinely check that hazard signage matches the vessel’s safety plan during survey, so carrying a correctly specified flammable liquid warning sign helps avoid deficiencies.

Installation Recommendations

Mount this flammable liquid warning sign at eye level on or immediately beside the entrance to any space where flammable liquids are stored, transferred, or used, and repeat it on tank access hatches, bunkering manifolds, and paint locker doors. Clean the substrate thoroughly before fitting a self-adhesive version, and use mechanical fixings on textured or curved bulkheads where adhesive alone may not hold in a marine environment.
