Class 2.2 Non-Flammable Non-Toxic Gas Sign

Class 2.2 Non-Flammable Non-Toxic Gas Sign

Class 2.2 Non-Flammable Non-Toxic Gas Sign – The dangerous goods diamond signs are used in areas where hazardous substances are being transported or may be stored. The ‘Class 2.2 Non-Flammable Non-Toxic Gas Sign’ shows a representation of a gas cylinder over the words non-flammable non-toxic gas accompanied by a bold number 2. Any examples of ‘Class 2.2 Non-Flammable Non-Toxic Gas Sign’ include oxygen, carbon dioxide, compressed air and helium as a reference.

One must use caution around inert gases to prevent injury. Such gases should not be treated as ‘harmless’ rather than handled with great caution. There are a number of risks and hazards associated with the storage of non-flammable, non-toxic gases including:

1. Such types of gases that spill into a confined space can displace the oxygen in the air causing a threat of asphyxiation.
2. Any damage to the cylinder can rapidly disperse gas, rupture or even explode.
3. The heat from explosions, industrial machinery and even direct sunlight can cause cylinders to violently burst from the build-up of pressures. Hence, Posting the ‘Class 2.2 Non-Flammable Non-Toxic Gas Sign’ at correct places may prevent serious injuries at the workplace.

Classifications:

Properties of hazardous substances have been classified so to determine the best way the risks can be managed. They have been classified into eight key hazard classes:

•  1: Explosives.
•  2: Flammable gases.
•  3: Flammable liquids.
•  4: Flammable solids.
•  5: Oxidising substances.
•  6: Substances toxic to people.
•  8: Corrosive substances.
•  9: Substances toxic to the environment.

FAQ

1. What does a Class 2.2 Non-Flammable Non-Toxic Gas Sign mean?
   It identifies gases that are not flammable and not toxic, but may still pose hazards such as pressure risks or asphyxiation if released. Examples include nitrogen, helium, and carbon dioxide.

2. Where should Class 2.2 Gas Signs be displayed?
   They are required on transport vehicles, cylinder storage areas, and depots handling non-flammable gases, in compliance with NZ and Australian regulations.

3. What size sign should I use?
   Transport placards must be 250 mm minimum. The 120 mm size is useful for cylinder cages or cabinets, while larger sizes (400–800 mm) are ideal for warehouses, depots, and outdoor placement.

Note on 120 mm size: The 120 mm option is not compliant for transport placards, as NZ regulations require a minimum of 250 mm per side for vehicle use. However, it is very useful for small-scale applications such as cylinder cages, storage cabinets, and indoor warning signage where space is limited.

Note on larger sizes (400 mm – 800 mm): While 250 mm is the minimum required size for transport placards, larger signs (400 mm, 600 mm, 800 mm) are recommended for warehouses, depots, bulk storage areas, and outdoor use. The extra size improves long-distance visibility and makes hazards clear to staff, visitors, and emergency responders.

How to choose the right mounting options.

Corflute: short term less than 2 years outdoors

Thin PVC: Medium term, more than 2 years

ACM: Long term 5 years or more

Supplied as a sticker:

long term digital print laminated for long term use. With a life of 5 years or more. We use a Hi Tac vinyl which allows it to be applied most surfaces.

Magnetic mounting option for the Class 2.2 Non-Flammable Non-Toxic Gas Sign

Flexible, vehicle-grade magnetic placards with the Class 2.2 Non-Flammable Non-Toxic Gas Sign printed on premium vinyl, laminated, and mounted to automotive magnetic sheeting. They stick to ferrous steel panels and remove without residue—ideal for vehicles that only carry DG sometimes.

Who they’re for

• Contractors / couriers who transport Dangerous Goods occasionally

• Hire or multi-use vehicles (no permanent signage)

• Sites that swap classes depending on load (quick changeover)

• Size: 250 × 250 mm (meets common road minimums).

• Magnet: vehicle-grade sheet, 0.8–1.0 mm thick (30–40 mil), high-energy.

• Face film: outdoor self-adhesive vinyl + UV laminate (gloss).

• Operating temp: suitable from winter cold to summer heat (typical automotive range).

• Print: high-contrast black/white artwork.

Where they work (and don’t)

• Works on: painted steel panels that are flat, clean, and smooth.

• Doesn’t work on: aluminium, stainless, plastics, composites, heavy body filler; vinyl wraps, ceramic coatings, heavily textured paint.

• If customers have aluminium doors/ute trays, suggest self-adhesive or rigid ACM instead.

Fitment checklist

1. Clean & dry the panel (no wax/polish).

2. Warm, flat magnet—no curl.

3. Apply to flat steel only; press from centre out.

4. Do not bridge panel gaps, ribs or sharp curves.

5. Remove daily to clean/dry both surfaces; store flat.

6. In heavy rain/highway speeds, check edges haven’t lifted.

Care & maintenance

• Remove and wipe after wet weather; store flat (never rolled tight).

• Move position slightly each week to avoid differential fading.

• Avoid use on freshly resprayed paint (allow full cure).

Compliance note

• Magnet is a mounting method. The operator must ensure placards are the correct class, size, and securely affixed for the journey. Some carriers or site rules may require permanent/rigid placards—check your procedure.

NZS/AS 1319:1994 advocates simplicity and clarity in safety signage. To be effective, they should be easy to read and interpret at a glance.

The Standard is about the use of legible text and appropriate, simple symbols.

By simplifying the message, it reduces the risk of misinterpretation, which increases the chances of the sign’s warning or instruction being followed.

Enhancing the signs visibility through placement and colour

Placement and visibility will play a crucial role in the efficiency of safety signs.

The standard states that signs must be positioned near the hazard they are warning about, which ensures that the safety message is relevant. Also it advocates the use of contrasting colours for the background and lettering. This attention to the colour scheme will increase visibility and readability from a reasonable distance, which ensures the message is accessible.
