Workplace Hazardous Materials Information System

WHMIS is a plan that provides information in Canadian workplaces about hazardous materials that could potentially harm people, it works to educate people product labels, material safety data sheets (MSDS) and worker education programs.

1. Compressed Gas- Any type of gas that is under pressured or has been chilled, and put in a cylinder can be considered compressed gas. It is hazardous because if the container is broken, it can be dangerous to anyone close by as it travels at great speed.

2.Oxidizing Material- This type hazard isn't danger by itself, but it can aid other materials to catch fire as it provides oxygen and that is necessary for a fire to occur.

3.Flammable and Combustible Materials- Flammable materials catch fire easily at normal temperatures (below 37.8 degrees C or 100 deg F). Combustible materials usually need to be provided with heat over normal temperature (between 37.8 and 93.3 deg C or 100 and 200 deg F) to catch fire.

4. Poisonous and Infectious Materials(Causing Immediate and Serious Toxic Effects)- These materials can be life threatening as they're poisonous. They can come into affect in a few minutes or in a few hours, leading to loss of conciseness, burns, coma or death.

5. Poisonous and Infectious Materials (Causing Other Toxic Effects)- These materials are also toxic, but they're not quick to react and if so, it's a very temporary reaction. Even though these materials don't have immediate reactions they still can cause: cancer, allergies, reproductive system problems, harm to the baby, change to your genes, chronic effects.

6. Bio hazardous Infectious Material- These materials include toxins that can causes diseases in people or animals. They make also cause serious illness or death. These organisms live in body tissues or fluids, they can be treated as toxic.

7. Corrosive Material- These materials can burn skin on contact, and hurt human tissue like the eyes and lungs. Corrosives can cause permanent scarring, blindness, lung injury, or death. This hazard can also attack metal and weaken it causing it to collapse.

8. Dangerously Reactive Material- These materials are strongly reactive and release toxic gas quickly with water provided. These materials react dangerously in circumstances such as, being dumped or dropped, temperature increasing, or pressure increasing.

The four components of WHMIS are:

  • Hazard and product classification.
  • Labels
  • Material safety data sheets (MSDS)
  • worker education and worksite specific training (this education can still be applied in science and chemistry labs)

What is SDS?

SDS stands for Safety Data Sheet. It is an important component of product stewardship,occupational safety and health, and spill-handling procedures. They are an important resource for workplaces and workers to help you learn more about the procedure(s) used. You can use the information to identify the hazards of the products you use and to protect yourself from those hazards, including safe handling and emergency measures.

The signs you should watch out for


  1. Fire hazard-meaning dont keep it near oil or fuel or also it can burst into flames
  2. Oxidizers is the symbol that has a circle and then a flame behind it. It is a chemical that requires fuel to make it burn
  3. Exploding bomb ( for explosion or reactivity hazards)
  4. Compressed gas can be released deliberately by opening the cylinder valve, or accidentally from a broken or leaking valve or from a safety device. Even at a relatively low pressure, gas can flow rapidly from an open or leaking cylinder, which is what it looks like
  5. `corrosives are substances that can cause an erosion and the symbol has a hand with a liquid burning/dissolving matter
  6. Health hazard-may cause or suspected of causing serious health effects
  7. Exclamation mark-May cause less serious health effects but damage the ozone layer
  8. Skull and cross bones means it can cause death or toxicity with short exposure to small amounts
  9. Environment-If disposed outside (which is illegal) it may cause damage to the aquatic environment
  10. Bio hazardous Infectious Materials- For organisms or toxins that can cause diseases in people or animals

Protocols/what to do if touched

SDS tells users what the hazards of the product are, how to use the product safely, what to expect if the recommendations are not followed, how to recognize symptoms of exposure, and what to do if emergencies occur
  1. Identification; for the product and supplier
  2. Hazards: Physical (fire and reactivity) and health
  3. Prevention: Steps you can take to work safely, reduce or prevent exposure, or in an emergency
  4. Response: appropriate responses in various situations _e.g.., first aid, fire, accidental release)

For most people who work with hazardous products you should always:

  • Read the name of the chemical
  • Know the hazards
  • Understand safe handling and storage instructions
  • Understand what to do in an emergency situation
  • Make sure that the product is being used in the way manufacturer intended; otherwise the advice provided in the SDS and label may not apply, or the protective measured may not be adequate
Everything you need to know should be written in here and be kept where its possible for everyone to use.

How To Dispose Of Product

Below is written everything you need to know on what do to keep yourself safe when handling dangerous chemicals.
