Gas Under Pressure Sign – Remove Cylinders in Fire IS0003

Gas Under Pressure Sign – Remove Cylinders in Fire IS0003

This gas under pressure sign carries two linked instructions in one fixture: a blue information panel reading “In case of fire, remove cylinders to a safe area” above a yellow warning panel marked “Gas under pressure” with the standard exclamation warning triangle. Together they tell crew and visiting contractors exactly what a compressed gas store or cylinder rack requires during a fire emergency, rather than relying on a generic hazard symbol alone.

As SKU IS0003 in the Hazard Signs range, it is intended for gas bottle stores, welding bays, galley gas lockers and any compartment where pressurised cylinders are racked or stowed. The combined pictogram-and-instruction format gives firefighting teams and duty crew an immediate action to take, not just a warning to be cautious, which matters most in the first minutes of a fire response when cylinders exposed to heat present a real rupture and projectile risk.

The sign is built on self-adhesive film (see Materials below), giving it a strong glow rating after normal light exposure so the instruction remains legible if lighting fails during an emergency. The waterproof, saltwater-resistant, glossy wipe-clean construction suits engine rooms, deck lockers and other compartments where pressurised gas cylinders are exposed to washdown, condensation and general wear.

Why This Gas Under Pressure Warning Matters

Cylinders under pressure that are exposed to fire heat can rupture violently or vent uncontrolled gas as internal pressure rises, turning a contained fire into a much larger incident within minutes. Marking every gas store with a sign that states the required action clearly means crew do not have to recall a separate procedure under stress — the instruction to remove cylinders to a safe place is printed directly on the hazard itself. This supports faster, safer decision-making during drills and real emergencies alike, and gives supervisors a clear reference point during safety rounds of gas storage areas.

Compliance and Certification

The pictogram and wording follow the ISO 7010 registered safety sign format for compressed gas hazards, combined with a supplementary instruction panel consistent with general IMO shipboard safety signage guidance. Marking pressurised gas storage with a clear gas under pressure sign supports SOLAS general fire safety provisions and is the kind of documented hazard control that flag-state surveyors, classification societies and Port State Control inspectors expect to see wherever gas cylinders are stored aboard.

Installation Recommendations

Fit this sign directly on or immediately beside the cylinder rack or gas locker door, at eye level where it will be seen before the space is entered. Use the pre-drilled fixing holes for a permanent mechanical fixing in machinery spaces and open decks, or the self-adhesive backing on smooth painted surfaces where drilling is not practical. Check it during routine deck and compartment rounds to confirm both panels remain legible and the cylinder store beneath it is correctly racked and secured. Where multiple gas types are stored in the same locker, fit one gas under pressure sign per rack or bank of cylinders rather than a single notice for the whole space, so the instruction is unambiguous regardless of which bank is affected.

• Combined ISO 7010 pictogram and instruction panel for compressed gas hazards
• Waterproof, saltwater-resistant, glossy wipe-clean finish
• Suits gas bottle stores, welding bays and galley gas lockers

Fit this sign at every cylinder rack or gas store so crew know exactly what to do if fire breaks out nearby, and pair it with the vessel’s other compressed-gas and hazard warning signage as part of a consistent fire response plan.
