Workplace Hazardous Materials Information System

WHMIS Training Outline

Introduction

Labels (Types, Content, Design)

Material Safety Data Sheets     (MSDS)

Responsibilities of workers and supervisors

WHMIS Test

Why is WHMIS important?

•Requirement of the Ontario Occupational Health and Safety Act

•Awareness of risk and hazards in Workplace

•“Due Diligence”

Due Diligence

The law requires that we act with due diligence, which means that we must demonstrate that we took all reasonable care in carrying out our activities, e.g., in laboratories

Worker’s Responsibilities

Responsibilities of workers include:

·using personal protection and safety equipment as required by the employer

·following safe work procedures

·knowing and complying with all regulations

·reporting any injury or illness immediately

·reporting unsafe acts and unsafe conditions

Responsibilities

To fulfill their individual responsibilities, workers (employees, professors, contract personnel) must:

•know what these responsibilities are

•have sufficient authority to carry them out (organizational issue)

•have the required ability and competence (training or certification required)

•

•Note: While not technically “workers”, students and volunteers are considered as “equivalent to”

Worker’s Rights

·right to refuse unsafe work

·right to participate in the workplace health and safety activities through Joint Health and Safety Committee (JHSC) or as a worker health and safety representative

·right to know, or the right to be informed about, actual and potential dangers in the workplace

Supervisor’s Responsibilities

·instructing workers to follow safe work practices

·enforcing health and safety regulations

·correcting unsafe acts and unsafe conditions

·ensuring that only authorized, adequately trained workers operate equipment

·reporting and investigating all accidents/incidents

·inspecting own area and taking remedial action to minimize or eliminate hazards

·ensuring equipment is properly maintained

·promoting safety awareness in workers

Workplace Hazardous Materials Information System

•To provide information on hazardous materials used in the workplace

•To facilitate the process of hazard identification

•To ensure consistency of hazard information in all Canadian workplaces

Key Elements of WHMIS

Labels (Identification): 

•Supplier

What is  a Hazardous Material?

A: Compressed Gases

B: Flammable and Combustible

D1: Immediate effects

D2: Other toxic effects

E: Corrosives

D3: Biohazardous agents

C: Oxidizers

F: Dangerously reactive

Compressed Gas
Definition

Gas at room temperature

Compressed gases

Dissolved gases

Gases liquefied by compression

Refrigerated gases

Flammable and Combustible

1: Flammable Gas

2: Flammable liquids

3: Combustible liquids

4: Flammable solids

5: Flammable aerosols

6: Reactive flammable materials

Flammable and Combustible
Flammable Liquids

Flashpoint

< 37.8 °C

Ethanol

THF

Toluene

Acetone

Methanol

Hexane

Oxidizing Materials Oxidizers

Causes or contributes to the combustion of another material by yielding oxygen or any other oxidizing substance

Nitrates (ammonium nitrate), nitrites

Bromates, chlorates

Perchlorates, permanganates

Nitric acid

Poisonous and Infectious

3 Divisions

•  Materials causing immediate and serious toxic effects (two sub divisions)

•  Materials causing other toxic effects (Two sub divisions)

•  Biohazardous infectious material

LD50 is lethal dose for 50% of test animal population

LC50 is lethal concentration for 50% of test animal population (airborne)

Lethal Dose LD50/LC50

Materials causing Immediate and Serious Toxic Effects

Immediate symptoms, e.g., nausea, headache, vomit

Sub-division A: Very Toxic (low LD50 and LC 50)

Benzene, chlorine, phosphine

Sub-division B: Toxic (higher LD50 and LC50)

Materials Causing Other Toxic Effects

Longer term effects, e.g., carcinogens, mutagens, sensitizers

• Ethidium Bromide (mutagen)

• Halothane (teratogen)

• Acrylamide (neuro toxic)

• Formaldehyde (suspected carcinogen)

•

Biohazardous Infectious Material

Viruses (HIV, flu, Hepatitis)

Bacteria (E.coli, salmonella, strep)

Blood

Animal or human tissue

Tissue culture cells

Corrosive Materials

Substances that corrode steel or destroy human/animal tissue

Acids: Sulphuric acid

Bases: Sodium hydroxide

Gases: Chlorine

Dangerously Reactive Material

Reacts violently with water to produce a poisonous gas, e.g., alkali metal cyanides

Undergoes vigorous polymerization, decomposition, or condensation, e.g., 1,3-butadiene

Becomes self reactive under conditions of shock, friction or increase pressure or temperature, e.g., metal azides, dry picric acid

WHMIS Labels

Two types of WHMIS label:

•Supplier

•Workplace

First line of information

Identifies hazardous material in container

Draws attention to MSDS

Alert to dangers and hazards of product

Supplier Label
Required Elements

Name of product

Name of supplier, e.g., BDH, Fisher

Reference to MSDS

Hazard Symbols

Risk phrases

Precautionary measures

First aid measures

Design Requirements

•Label should be in French and English

•Should have a distinctive hatched border (some labels excepted)

•Must be legible and displayed so can be seen

•Must be sufficiently durable to remain attached under normal lab conditions

Supplier Label

Exceptions to Supplier Label

•Containers < 100 ml

•Supplies from a stores facility

•Laboratory samples, e.g., samples sent away for analysis

•Labels from a laboratory supply house, e.g., BDH, Fisher, Sigma-Aldrich

Workplace Labels

•Used when no supplier label present

•Usually prepared by the lab or faculty

•Science stores prepares workplace labels upon request

•Medicine stores has blank workplace labels and hazard pictograms to be completed by lab personnel

•Home made labels acceptable

Workplace Labels
Examples of use

•Product purchased prior to WHMIS (1988)

•Original supplier label lost, defaced or illegible

•Experimental sample for use in the lab (NOT reaction intermediates)
