WHMIS Hazard Classifications
9

• Compressed Gas
• Any Hazardous Material that is contained under
  pressure including compressed gas, dissolved gas,
  or liquefied gas

10
Compressed Gas Cylinders

• store and transport with safety cap, because
• comply with storage restrictions, because
• DO NOT store fuel gas with oxygen, because
• secure in an upright position, because
• use in a well ventilated area, because
• use the proper type of regulator and know its
  history, because

11

• Flammable and Combustible Material
• Flammable Gases
• Flammable and Combustible Liquids
• Flammable Solids
• Flammable Aerosols
• Reactive Flammable Material

12
Flammable Materials

• Store liquids in Flammable Storage Cabinet
• Explosion-proof fixtures required
• Pour larger quantities in fume hood
• NEVER store with oxidizers
• Keep away from heat, ignition sources, and direct
  sunlight
• Use static lines when transferring

13

• Oxidizing Material
• Any Hazardous Material which causes or
  contributes to the combustion of another material
  by giving oxygen or some other oxidizing
  substance, whether or not it is combustible.
• Eg. Pool spa test strips, ozone, bleach

14
Oxidizers

• Easily oxidize metal powders, organic materials
• Segregate from other materials, such as organic
  solvents
• PPE and/or Explosion barriers may be required

15

• Poisonous Infectious Materials
• (Class 1)
• Material causing immediate and serious toxic
  effects
• Materials which are potentially fatal or may
  cause permanent damage if inhaled, swallowed, or
  absorbed through the skin, or may burn the skin
  or eyes upon contact

16

• Poisonous Infectious Materials
• (Class 2) Toxic Materials
• Material causing other chronic or long term
  effects
• Material which may cause death or permanent
  damage as a result of repeated exposure over an
  extended period of time may be an irritant to
  the skin, eyes, or respiratory system may cause
  cancer, birth defects, or sterility.

17

• Poisonous Infectious Materials
• (Class 3)- Biohazards
• Materials which may cause disease in humans and
  animals, such as viruses, bacteria, and fungi
  may also include cultures and diagnostic
  specimens such as blood, urine, and body tissue.

18

• Corrosive Material
• Material which may corrode aluminum and steel or
  human flesh
• Can be liquid or gases

19

• Dangerously Reactive Material
• Materials which become self-reactive under
  conditions of shock, or increased temperature or
  pressure
• Materials which react vigorously with water to
  produce a very toxic gas

20
General Dry Chemicals

• Relatively innocuous or unreactive
• No special storage requirements

21
Chemical Compatibility

• Never store incompatible materials together
• Vapours will react
• Use a Chemical Compatibility Chart
