Physical Hazards

Physical hazard are based on the intrinsic properties of the chemical. There are five main classes of physical hazard namely Explosive, Flammable, Oxidising, Gases under Pressure and Corrosive to metals. These are then sub-divided into different categories depending on the degree of danger and these are assigned specific hazard statements to identity them.

ExplosiveGHS01-explosive

May explode if exposed to fire, heat, shock, friction.

  • Avoid ignition sources (sparks, flames, heat)
  • Keep your distance
  • Wear protective clothing

FlammableGHS-02-flame

Flammable if exposed to ignition sources, sparks, heat. Some substances with this symbol may give off flammable gases in contact with water.

  • Avoid ignition sources (sparks, flames, heat)
  • Keep your distance
  • Wear protective clothing

OxidisingGHS03-oxidising

Can burn even without air, or can intensify fire in combustible materials.

  • Avoid ignition sources (sparks, flames, heat)
  • Keep your distance
  • Wear protective clothing

Gas under Pressure GHS04-bottle

Contains gas under pressure. Gas released may be very cold. Gas container may explode if heated.

  • Do not heat containers
  • Avoid contact with skin and eyes

 Corrosive GHS05-Corrosive

 

May corrode metals.

  • Keep away from metals
