Class 2 - Gases: Compressed, Liquefied or Dissolved Under Pressure

Toxic Gas 2.3

Toxic Gas Sign 2.3

Division 2.3: Toxic gases

  • Gases which are known to be so toxic or corrosive to humans as to pose a hazard to health.
  • Gases which are presumed to be toxic or corrosive to humans because they have an LC50 value equal to or less than 5000 ml/m³ (ppm).
100mm x 100mm – 1000/roll
50mm x 50mm – 1000/roll
25mm x 25mm – 3000/roll
20mm x 20mm – 3000/roll
Flammable Gas 2

Class 2 - Flammable Gases 2.1

  • Division 2.1: Flammable Gases.  Gases which at 20 °C and a standard pressure of 101.3 kPa:
    • are ignitable when in a mixture of 13 per cent or less by volume with air; or
    • have a flammable range with air of at least 12 percentage points regardless of the lower flammable limit.
100mm x 100mm – 1000/roll
50mm x 50mm – 1000/roll
25mm x 25mm – 3000/roll
20mm x 20mm – 3000/roll
Non Flam Non Toxic Gas 2

Class 2 - Non-Flammable Gas 2.2

  • Division 2.2: Non-flammable, non-toxic gases
    • Gases which are asphyxiant – gases which dilute or replace the oxygen normally in the atmosphere.
    • Gases which are oxidizing – gases which may, generally by providing oxygen, cause or contribute to the combustion of other material more than air does.
    • Gases which do not come under the other divisions.
      100mm x 100mm – 1000/roll
      50mm x 50mm – 1000/roll
      25mm x 25mm – 3000/roll
      20mm x 20mm – 3000/roll
Oxidizing Gas 2

Class 2 - Oxidising Gas 2.5

  • Division 2.5: Oxidising Gases
    • An oxidising gas is any gas which may, generally by providing oxygen, cause or contribute to the combustion of other material more than air does.
100mm x 100mm – 1000/roll
50mm x 50mm – 1000/roll
25mm x 25mm – 3000/roll
20mmff x 20mm – 3000/roll
Gases Under Pressure

Gases under pressure RED OUTLINE

Gases under pressure – Gases stored under pressure, such as ammonia or liquid nitrogen.

100mm x 100mm – 1000/roll
50mm x 50mm – 1000/roll
25mm x 25mm – 3000/roll
20mmff x 20mm – 3000/roll
