There are three divisions within Class D. Division 1 (D-1): Materials Causing Immediate and Serious Toxic Effects: These are products, substances, and materials that may cause acute lethal effects, immediately or within 24 hours following a single dose exposure to a toxic material. Products that cause such effects have low LC50 and LD50 values.
- Division 1 - Materials Causing Immediate and Serious Toxic Effects.

What are Category 1 and 2 hazards?
Hazards are divided into two categories. Those which score high on the scale (and therefore the greatest risk) are called Category 1 hazards. Those that fall lower down the scale and pose a lesser risk are called Category 2 hazards.
Is Category 3 High risk?
Category 1 is always the greatest level of hazard (that is, it is the most hazardous within that class). If Category 1 is further divided, Category 1A within the same hazard class is a greater hazard than category 1B. Category 2 within the same hazard class is more hazardous than category 3, and so on.
How many hazard groups are there?
These nine pictograms make up the most recognized part of GHS, but there is more. In addition to the pictograms, GHS also breaks up the hazards into different groups that have things in common.

WHMIS classes or classifications
WHMIS (Workplace Hazardous Materials Information System) uses classifications to group chemicals with similar properties or hazards. The Controlled Products Regulations specifies the criteria used to place materials within each classification. There are six (6) classes although several classes have divisions or subdivisions.
Class A – Compressed Gas
Any material that is normally a gas which is placed under pressure or chilled, and contained by a cylinder is considered to be a compressed gas. These materials are dangerous because they are under pressure. If the cylinder is broken, the container can ‘rocket’ or ‘torpedo’ at great speeds and this is a danger to anyone standing too close.
Class B – Flammable and Combustible Material
Flammable means that the material will burn or catch on fire easily at normal temperatures (below 37.8 degrees C or 100 deg F). Combustible materials must usually be heated before they will catch on fire at temperatures above normal (between 37.8 and 93.3 deg C or 100 and 200 deg F).
Class C – Oxidizing Materials
Oxygen is necessary for a fire to occur. Some chemicals can cause other materials to burn by supplying oxygen. Oxidizers do not usually burn themselves but they will either help the fire by providing more oxygen or they may cause materials that normally do not burn to suddenly catch on fire (spontaneous combustion).
Class D – Poisonous and Infectious materials
Class D materials are those which can cause harm to your body. They are divided into three major divisions.
Class E – Corrosive Material
Corrosive is the name given to materials that can cause severe burns to skin and other human tissues such as the eye or lung, and can attack clothes and other materials including metal. Corrosives are grouped in this special class because their effects are permanent (irritants whose effects may be similar but temporary are grouped in Class D-2).
Class F – Dangerously Reactive Materials
A material is considered to be dangerously reactive if it shows three different properties or abilities: first, if it can react very strongly and quickly (called “vigorously”) with water to make a toxic gas; second, if it will react with itself when it gets shocked (bumped or dropped) or if the temperature or pressure increases; and thirdly, if it can vigorously join to itself (polymerization), break down (decomposition) or lose extra water such that it is a more dense material (condensation).

What are hazard categories?
The hazard categories are assigned a number (e.g., 1, 2, etc.) Categorie s may also be called "types". Types are assigned an alphabetical letter (e.g., A, B, etc.). In a few cases, sub-categories are also specified. Subcategories are identified with a number and a letter (e.g., 1A and 1B).
What are the four classes of flammable solids?

What is classified as a division 5?

What is the term for the production of irreversible tissue damage to the skin as a result of chemical reaction between
Corrosives are materials or substances that will corrode steel, destroy aluminum or human tissue at the site of contact. Corrosion is the production of irreversible tissue damage to the skin as a result of chemical reaction between the product and dermal tissue. It differs from irritation, which is the production of reversible
What is the flashpoint of a substance in Division 3?
product, material, or substance is classified into Division 3 if it has a flashpoint of 37.8° C (100° F) or more but less than 93.3° C (200° F).
Can you sell WHMIS without a label?
Partially exempt products, which are labelled under federal legislation other than WHMIS, can be sold without WHMIS labels and MSDSs. However, when these products are used in the workplace, provincial OSH regulations require worker education and training, and workplace labels must be applied if they are not in their original containers.
