GHS Hazard Classification. GHS uses three hazard classes: Health Hazards, Physical Hazards and Environmental Hazards.

A WHMIS GHS program is required in all Alberta workplaces that may have controlled products. Employers must provide workers with information regarding safety and health hazards in their workplaces.

There are only two signal words in GHS: "Danger" or "Warning". They are used to emphasize chemical hazards and indicate the relative level of severity of the hazard. "Danger" indicates more severe hazards. Signal word is one integral part of a GHS label.

GHS Hazard Classification. GHS uses three hazard classes: Health Hazards, Physical Hazards and Environmental Hazards. These aren't required by OSHA. Health hazards present dangers to human health (i.e. breathing or vision) while physical hazards cause damage to the body (like skin corrosion).

WHMIS/GHS/(M)SDS WHMIS has changed to incorporate the Globally Harmonized System of Classification and Labelling of Chemicals (or GHS) for workplace chemicals.

The newly revised HCS outlines eight specific GHS pictograms for use on labels. Each is surrounded by a red border and designed to convey the health and physical hazards of chemicals. A ninth, environmental pictogram may be required by other agencies, but not by OSHA.

So a short course on the SDS sections is in order. There are 16 in all, four of which are not mandatory, per OSHA. This section lists the chemical's recommended uses, the supplier's contact information and emergency phone number, and common names and synonyms for the product.

Acute toxicity includes five GHS categories from which the appropriate elements relevant to transport, consumer, worker and environment protection can be selected. Substances are assigned to one of the five toxicity categories on the basis of LD50 (oral, dermal) or LC50 (inhalation).

It is confronted with the criteria for pesticide classification recommended by the WHO which it suitably completes. Acute toxicity makes it possible to classify pesticides into five classes: class I - highly toxic, class II - toxic, class III - moderately toxic, class IV - slightly toxic, class V - virtually non-toxic.

The HACCP plan is designed to control all reasonably likely food-safety hazards. Such hazards are categorized into three classes: biological, chemical and physical. Biological hazards include harmful bacteria, viruses or parasites (e.g., salmonella, hepatitis A and trichinella).
1033766
There are two broad types of hazards associated with hazardous chemicals, which may present an immediate or long-term injury or illness to people. These are health hazards and physiochemical hazards. Many chemicals have both health and physicochemical hazards.

Try to include at least one product from each of the four categories used by the EPA to classify hazardous waste: ignitable, corrosive, reactive and toxic. Include safe cleaning alternatives such as vinegar, baking soda, salt and lemon juice.
