Gas Tag

Gas Tag for Flagging Gas Hazards and Compartments

The Gas Tag is a punched hang-tag used aboard ships and in port and terminal facilities to flag valves, pipework, tanks, or compartments where a gas hazard is present, including toxic, flammable, or asphyxiant gases. Confined space and enclosed compartment gas hazards are among the leading causes of serious marine incidents, so clear point-of-use warning before entry or work is essential.

When to Use This Tag

Attach the Gas Tag to valves, manifolds, tank hatches, or compartment access points where gas may be present, has recently been present, or where atmosphere testing is required before entry. It is also used during lockout/tagout (LOTO) and enable/disable procedures for gas-fitted equipment, and to flag compartments undergoing gas-freeing or ventilation prior to hot work or confined space entry.

Design and Materials

Each tag features a hazard warning triangle with an exclamation mark pictogram above a bold “GAS” panel, printed on fire-retardant, photoluminescent laminated card stock a long-duration afterglow. This ensures the warning remains visible during power loss or in poorly lit compartments such as tank spaces, pump rooms, and cargo holds. The card is waterproof and resistant to saltwater exposure, making it suitable for prolonged use in marine and offshore environments. A reinforced punched hole at the top allows the tag to be secured with a cable tie or wire loop.

Installation and Use

Loop a cable tie or wire tie through the punched hole and secure the tag directly to the affected valve, hatch, or compartment access point, ensuring the warning panel faces outward and remains clearly legible. The “Authorised by” and “Date” fields at the base of the tag should be completed by the person applying it, providing a simple accountability record consistent with standard permit-to-work and lockout/tagout documentation practices. Because the tag is a physical hang-tag rather than an adhesive label, it can be quickly attached, removed, or transferred between items as required without leaving residue or damaging equipment surfaces.

Compliance and Standards

The tag’s pictogram and signal word follow internationally recognised hazard communication conventions used across the maritime and industrial safety sectors, aligning with IMO Resolution A.1116(30) guidance on shipboard signage and supporting broader confined space and gas safety obligations such as those set out by Safe Work Australia. Vessel operators should confirm the tag meets any flag-state or class-specific requirements applicable to their enclosed space entry and gas safety management system.
