Flammable Gas 2 Diamond (Roll of 100 Labels) - Safety Signs by Caledonia Signs

A Flammable Gas Class 2 diamond label is a vital safety symbol used to indicate that a container or vehicle holds gases that can ignite easily when mixed with air and exposed to an ignition source. It features a red diamond with a flame icon and the number "2", denoting Class 2 hazardous materials – flammable gases, as per international standards like the UN Globally Harmonised System (GHS) and ADR regulations. The label warns of fire and explosion hazards, guiding safe handling, transport, and emergency response.

These labels are used wherever flammable gases such as propane, butane, acetylene, methane, hydrogen, or LPG are stored or transported. You will typically find them on gas cylinders, pressure tanks, gas supply trucks, industrial pallets, and containers in factories, laboratories, welding shops, fuel distribution centres, and medical facilities. They are also used in commercial kitchens and construction sites where portable gas equipment is employed.

The primary reason for using Flammable Gas 2 labels is to reduce the risk of fire, explosion, or chemical accidents. These labels alert workers, handlers, and first responders to the presence of volatile gases that require strict safety protocols, such as avoiding sparks, static discharge, heat, and using appropriate ventilation. Proper labeling is also legally required under transport regulations such as the ADR (road), IMDG (sea), IATA (air), and OSHA/HSE guidelines for workplace safety.

Flammable Gas 2 diamond labels must be placed clearly and prominently on all sides of cylinders, tanks, or vehicles carrying such gases. Their consistent design ensures that hazards are instantly recognised, even across language barriers, allowing for quick and informed decisions in both routine handling and emergency situations. These labels are a critical part of any hazardous materials management system, helping to protect people, property, and the environment.
