Health & Safety Orientation and WHMIS Overview for Chemical Engineering January 12, 2006 1

2

Reason for the Session • Persons in authority (Employers, Professors, etc. ) have a duty to inform and train those under their supervision to ensure their wellbeing (Safety & Health Legislation) • This session is the beginning to this training. It will only be on some select aspects of health and safety, for it cannot possibly cover all the specific areas that you are or will be doing in your future. 3

Some Safety Topics • Emergency response information • Occupational Health and Safety Laws • Hazard Identification • Introduction to Toxicology Terminology • Orientation to WHMIS Regulations • Engineering Safety Controls • Exposure Control Plans • Personal Protective Equipment • Emergency Response Plans • Fire Safety - Evacuation Procedures • • • Confined Space Entry Respiratory Safety Lock-out, Tag-out System Electrical Safety Excavations & Trenching Scaffold Safety & Fall Protection Ergonomics Welding Safety Fork Lift Safety Transportation of Dangerous Goods Blood Borne Pathogen Standards (First Aid). 4

Health & Safety Rights Two Significant Health and Safety Events in Canada 12

In 1970 the Saskatchewan Occupational Health & Safety Act and Regulations were developed (updated in 93 & 96) 13

In 1984 WHMIS was introduced. Workplace Hazardous Materials Information System. 14

Occupational Health & Safety Laws Including WHMIS • Canada has legislation to protect employee’s health and safety and the environment • Federal government allocates some of this responsibility to each Province (eg WHMIS) • Provinces have their own legislation that directs the activities of people and organizations (eg safety orientation & training must be provided, SOHC, employees rights) • The regulatory bodies differ (eg WCB or DOL). 15

Employee’s Rights All employees in Saskatchewan have three basic Health and Safety Rights: • The right to know • The right to refuse • The right to participate. 16

Employee's Right to Know • To know about the presence of hazards in the workplace • To have access to information about the hazardous agents in the workplace (WHMIS) • To know what safety controls are available and how to use them; – procedural (SOP, ERP) – engineering (fume hoods etc. ) – PPE. 17

Employee's Right to Refuse Section 23 of OHS Act states: A worker may refuse to perform unusually dangerous work on reasonable grounds The procedure is laid out as follows: 1) Supervisor 2) Local Safety Committee 3) Dept of Health, Safety and Environment 4) Occupational Health Committee 18 5) Department of Labour.

Employee's Right to Participate You have the right to participate in your health and safety program (via election). 19

Health & Safety Responsibilities 20

Responsibilities of the University • employee training (general) • hazard assessment and audits • engineering controls (fume hood maintenance etc. ) • training and supervision are provided • general compliance requirements. 21

Responsibilities of the Supervisor or Principal Investigator u employee training (site specific) u first step in resolving concerns u safety controls provided: SOP, ERP, ECP, PPE u proper supervision u registration or permit in place u meet general compliance requirements. 22

Responsibilities of the Employee u comply with OH&S Act & Regulations u comply with University Codes & Standards u participate in training u apply knowledge & use safety equipment provided. 1/2 23

Responsibilities of the Employee u follow u work u PPE ECP, SOP & ERPs that are in place in a responsible manner is used and maintained appropriately u training u notify 2/2 and supervision are followed their supervisors about unsafe acts and conditions. 24

Statutory Occupational Health Committee One with overall responsibility l Requirement of the Act & Regulations l Minutes are public and go to DOL l Review accidents, policies and procedures l Provides legislative mechanism to address unresolved OH&S concerns. 25

Local Safety Committees There are 24 committees designated as Local Safety Committees. They form an important role in workplace safety. They: l Address local safety issues l Send minutes to the statutory committee for review l Have a representative from DHSE. 26

Any Questions? 27

Properties of Hazardous Materials and Toxicology 28

MSDS Terminology u LD 50 (mg/Kg): Lethal Dose 29

Let’s Look at Some Materials 30

MSDS Terminology u LD 50 (mg/Kg): Lethal Dose u LC 50 (ppm): Lethal Concentration u TLV-TWA : 8 hour day/40 hour week u TLV-STEL: 15 minutes u TLV-C: Never Exceeded u OT: Odour Threshold u UEL (LEL): Upper (Lower) Explosion Limit u Acute: Occurs immediately or after a single dose u Chronic: Due to long term exposure or after a long time. 31

Relative Hazard Potential One can get a relative hazard potential by using the LD 50 or LC 50 (acute) but you have to look at the following as well : u Chronic Toxicity - Long Term Effects u Does it target or accumulate in a system u Physical properties u Identifying how it will be used. 32

Properties that Increase Hazard u Boiling Point Low u Vapour Pressure High u Odour Threshold > TLV u Flash Point Low u Lower Explosion Limit Low u Flammability Range Large u Targets Certain Systems / Toxic u Other Properties Explosive, Carcinogenic etc.

Workplace Hazardous WHMIS = Material Information System 34

Salient Points to Regulations & WHMIS • Inventory Required - OHS Reg 303 • MSDSs must be available to all employees - OHS Reg 327 • All “Controlled Products” must be labeled - OHS Reg 319 • Employees must receive training u General safety orientation - OHS Reg 22 u Site specific safety orientation - OHS Reg 19 u Interpretation of hazard information - OHS Reg 318. 35

Exclusions Under WHMIS • • The Food and Drug Act The Pest Control Products Act Hazardous Wastes Consumer Products, Wood Products, Tobacco & Manufactured Articles • The Explosives Act • The Atomic Energy Control Act. 36

WHMIS 3 Main Points • Training: To do job safely and how WHMIS works • Labeling: Identify the hazards in the workplace • MSDS: Available for hazardous materials, know where they are and what is on them. 37

Hazard Identification System • • Symbols Supplier Labels Workplace Labels MSDS – Material Safety Data Sheet. 38
