A: Mix and Flow of Matter, section 1: WHIMIS and fluids Flashcards
What does WHMIS stand for?
Workplace Hazardous Materials Information System
https://whmis.org/
What is the purpose of WHMIS?
To warn people about dangerous materials in the workplace and to help decide how to store the materials safely.
exploding bomb
for explosion or reactivity hazards
Self-reactive substances and mixtures (Types A and B)
Organic peroxides (Types A and B)
flame
for fire hazards
Flammable gases (Category 1A and 1B Flammable gas; Category 1A and 1B Chemically unstable gas; Category 1A Pyrophoric gas) )
Aerosols (Category 1 and 2)
Flammable liquids (Category 1, 2 and 3)
Flammable solids (Category 1 and 2)
Pyrophoric liquids (Category 1)
Pyrophoric solids (Category 1)
Self-heating substances and mixtures (Category 1 and 2)
Substances and mixtures which, in contact with water, emit flammable gases (Category 1, 2 and 3)
Self-reactive substances and mixtures (Types B, C, D, E and F)
Organic peroxides (Types B, C, D, E and F)
Chemicals under pressure (Category 1** and 2**)
What is the danger of flammable and combustible material?
They could easily light on fire
Eg: paint thinners
flame over circle
for oxidizing hazards
Oxidizing gases (Category 1)
Oxidizing liquids (Category 1, 2 and 3)
Oxidizing solids (Category 1, 2 and 3)
What is the danger of oxidizing material?
Oxidizing material could make an existing fire worse
Eg Chlorine
gas cylinder
for gases under pressure
Gases under pressure (Compressed gas, Liquefied gas, Refrigerated liquefied gas, and Dissolved gas)
Chemicals under pressure (Category 1, 2 and 3)
What is the danger of compressed gas?
Compressed gas could explode or it could spin out of control if the canister breaks
Eg: propane
corrosion
for corrosive damage to metals, as well as skin and eyes
Corrosive to metals (Category 1)
Skin corrosion/irritation – Skin corrosion (Category 1, 1A, 1B and 1C)
Serious eye damage/eye irritation – Serious eye damage (Category 1)
What is the danger of corrosive material
Corrosive material could chemically burn you (not flames, but eating away at your skin or eating away at the metal for example)
Eg: Acid
What is the danger of reactive material?
It will react with other things
Eg: phosphorus (match head)
skull and crossbones
can cause death and toxicity with exposure to small amounts in a short period of time
Acute toxicity –
Oral (Category 1, 2 and 3)
Dermal (Category 1, 2 and 3)
Inhalation (Category 1, 2 and 3)
What is the danger of poisonous and infectious materials?
Poisonous and infectious materials could make you sick or kill you depending if the amount is over a certain threshold.
Eg: pesticides
health hazard
may cause or suspected of causing serious health effects
Respiratory or skin sensitization – Respiratory sensitizer (Category 1, 1A and 1B)
Germ cell mutagenicity (Category 1, 1A, 1B and 2)
Carcinogenicity (Category 1, 1A, 1B, and 2)
Reproductive toxicity (Category 1, 1A, 1B and 2)
Specific Target Organ Toxicity – Single exposure (Category 1 and 2)
Specific Target Organ Toxicity – Repeated exposure (Category 1 and 2)
Aspiration hazard (Category 1)
exclamation mark
may cause less serious health effects or damage the ozone layer
Acute toxicity – Oral, Dermal, Inhalation (Category 4)
Skin corrosion/irritation – Skin irritation (Category 2)
Serious eye damage/eye irritation – Eye irritation (Category 2 and 2A)
Respiratory or skin sensitization – Skin sensitizer (Category 1, 1A and 1B)
Specific target organ toxicity – Single exposure (Category 3)
environment
may cause damage to the aquatic environment
biohazardous infectious materials
for organisms or toxins that can cause diseases in people or animals
Biohazardous Infectious Materials (Category 1)
