WHMIS and GHS Overview

Study Notes

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.

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.
Biohazardous Infectious Materials: Includes infectious agents or biological toxins that can lead to serious diseases or death; used needles serve as a key example.
