Study Notes
WHMIS Overview
- WHMIS (Workplace Hazardous Material Information System) is a national hazard communication system in Canada.
- It provides crucial information on the safe use of hazardous products in workplaces.
- Transitioning to a new initiative, WHMIS is now part of the Global Harmonized System (GHS), aimed at standardizing chemical classification and communication globally.
GHS Symbols and Their Meanings
-
Gas Cylinder: Indicates gases under pressure, such as oxygen tanks.
-
Flammable: Represents materials that can easily catch fire, including propane gas.
-
Oxidizers: Materials that enhance the intensity of fires, exemplified by hydrogen peroxide.
-
Corrosive: Substances that chemically damage or destroy metals, causing severe skin burns and eye irritation; hydrochloric acid is a key example.
-
Explosive: Materials capable of self-reactivity or explosion, with potassium as a noted example.
-
Acute Toxicity: Refers to substances that can cause death or serious toxicity from short exposure to minimal amounts; carbon monoxide is a significant example.
-
Health Hazard: Materials that may cause or are suspected of causing serious health issues; asbestos is a notable example.
-
Irritants, Sensitizers, and Other Hazards: Chemicals that cause less severe health effects or damage to the ozone layer, such as various acids.
