Description
Flammable gas storage demands immediate visual warning. This sign covers acetylene, hydrogen, methane, propane, and other Class 2.1 gases per AS 4332, protecting personnel at cylinder cages, manifolds, and welding-bay compounds. Mount it where the storage area is visible from outside — regulatory compliance starts at the perimeter. Choose vinyl for indoor durability, polypropylene for wet environments, or Colorbond for permanent outdoor installation. Sizes from 180×250 mm to 225×300 mm suit most cage and manifold setups. Pair with the AS 1216 Class 2.1 hazard diamond for complete hazard communication. Platinum Signs delivers Australia-wide; trade accounts receive bulk discounts and custom hole-drilling at no extra cost.
Final sign type, wording, size, placement and material depend on the site risk, project specification and applicable jurisdiction. Confirm the requirement with the relevant WHS adviser or regulator.

Frequently asked
Does this sign need to be paired with a hazard diamond?
Yes — AS 4332 requires the Class 2.1 diamond (red background, black flame symbol) displayed alongside the no-smoking prohibition to complete hazard communication at the storage point.
Can I use this at a manifold inside a workshop?
Absolutely. Any location where Class 2.1 gases are decanted, stored, or transferred — whether a cage, manifold, or bay — requires this sign visible from the approach.
What's the best material for outdoor cylinder cages?
Colorbond offers superior UV and weather resistance for permanent outdoor installation; polypropylene suits exposed but semi-sheltered cages; vinyl works indoors or under cover.
Do you drill mounting holes?
Yes. Four-corner pre-drilled holes are an optional extra with a base surcharge of $3.00 inc GST per sign for the listed configurations, before any applicable volume discount. Select the option to update the configured total before adding to cart.
What's the lead time for bulk orders?
Automatic volume pricing is 5–9 signs: 8% off, 10–24 signs: 15% off, 25–49 signs: 24% off, 50–99 signs: 32% off, 100+ signs: 40% off. The configurator is the source of truth and updates the unit price as quantity changes.
