WHMIS Workplace Hazardous Materials Information System WHMIS The

WHMIS Workplace Hazardous Materials Information System

WHMIS Ø Ø The WHMIS provides workers and students with complete and accurate information regarding hazardous products. The regulations cover all worksites where chemicals are used. Workers and Students must learn and apply this information, provided on products labels and Material Safety Data Sheets (MSDS). The best time to learn WHMIS regulations is before using a potentially hazardous substance.

WHMIS Ø Ø The Key to the WHMIS system is clear and standardized labeling. The supplier is responsible for providing a label when the product is sold, and the workplace is responsible for ensuring that the labels remain intact or are replaced, if necessary. Smaller containers for student use are also labeled, listing the hazards and indicating where more information can be found.

WHMIS (Workplace Hazardous Materials Information Systems) The 3 components to the WHMIS system are: MSDS 2. Worker Education 3. Labels on all Products 1.

MSDS l Stored in binders in lab areas All known chemicals l 8 sections l § § § § name ingredients physical data fire hazards reactivity data toxicological properties preventive measures first aid measures

WHMIS SYMBOLS

WHMIS LABELS

Compressed Gas Ø It is dangerous and could explode because its contents are under a lot of pressure. Ø If there is too much heat, it can also explode. ØEx. helium, propane Øvideo

Accident with compressed gas

Flammable/Combustible Ø Dangerous when it is in contact with oxygen or heat. Ø Ex. methane gas, acetone, propane, ethanol Ø Video 2

Accident with flammable/combustible

Oxidizing Material Ø Risks of fire due to oxygen. Ø Ex. Chromic Acid

Poisonous Infectious (Immediate & Serious Toxic Effects) Ø These are materials that are very poisonous and immediately dangerous to life and health. Ø ex: cyanide, carbon monoxide

Poisonous Infectious (Other Toxic Effects) ØNo immediate danger, could be temporary but may lead to serious sickness or cause harm. Ø Can cause cancer ØEx. Mercury, lead, asbestos

Biohazardous Infectious Ø These materials are organisms or the toxins they produce that can cause diseases in people or animals. Included in this division are bacteria, viruses, fungi and parasites. As these organisms can live in body tissues and fluids, they should be treated as toxic. Ø Can cause death or extreme sickness Ø Ex: AIDS/HIV virus, Hepatitis B and salmonella.

Corrosive Materials Ø Corrosives can also damage or even destroy metal. They begin to cause damage as soon as they touch the skin, eyes, respiratory tract, digestive tract, or the metal. . Most corrosives are either acids or bases. Ø Ex. hydrochloric acid, sulfuric acid, nitric acid, chromic acid, acetic acid and hydrofluoric acid. Common bases are ammonium hydroxide, potassium hydroxide

Dangerously Reactive These have three properties: it reacts with water to make gas, it react by itself if shook, and it reacts if temp or pressure changes. Ex. Sodium - video

Household Chemical Research Assignment Find a chemical (Windex, Mr. Clean…) at home and find the following information from the labels on the container and/or by researching the internet. 1. 2. 3. 4. 5. Name of the product. Draw the HHPS or WHMIS symbols. Determine the actual chemicals in the product (no more than 5). What are some safety precautions you should take when using this product? What are some first aid measures for when you have been exposed to the product? (handout)
