Sean Kells • In November 1994, Sean Kells, 19 • Sean Kells was pouring a highly flammable chemical from one ungrounded drum to another when it exploded and ignited. Sean was not told that what he was doing was dangerous and that he should be taking precautions. Sean was engulfed in flames, he had burns to 90% of his body and died in hospital the next day. It was his third day of a part-time job at Pro-Shield Corp. in Mississauga, and the unidentified liquid was a rubberized protective undercoating.
Types of Hazards at school and at work • Chemical Cleaners, Science chemicals, Paints • Physical Electricity, Heat, Falling, Flame • Biological Flu, restrooms, mold, blood or tissue, e.coli • Ergonomic Posture Habits, Repetitive Tasks, Heavy Lifting, Lighting, Chairs • Radiation Lasers, welding, kilns
Common Workplace Hazards Cuts– Use of knives/grinder, paper cutters, wood working tools Burns – Hot glue guns, soldering irons, studio light bulbs, kitchen heat source, stove/oven Electric shock – Handle plugs with wet hands Shocks from plugs being not plugged in all the way Slips and Falls – Slippery wet floors - clean up spills around sinks, outside in winter Soreness and Back pain – Heavy lifting, bad posture at computer Itching, Swelling, redness of skin – Exposure to chemicals, detergents, cleaning solutions Coughing, wheezing, shortness of breath – Exposure to dust, additives, chemicals in the air
FIRE • Exits • Drills • Fire Extinguishers • Know where they are
Eye Wash Stations • Most technology classrooms have eye wash stations • USE THEM (it’s only water!)
Using Knives and Guillotine • X-acto Blades • Disposal of used blades (not in garbage) • Cut away from your hand • Put equipment away correctly • Guillotine – ASK TEACHER.One person at a time
Zero tolerance for fooling around when using equipment No pushing or horse play around equipment!! Be Good when out of Class 1 No risky stunts or climbing heights to take photos. 2 No Taking photos around running vehicles. 3 No use of cars during class time 4 Must stay on school property during class time
Tell Us • Report anything that looks unsafe • Report any injury or accident to your teacher immediately • Know your emergency procedures and where the equipment is
WHMIS Workplace Hazardous Materials Information System • WHMIS is law • Help stop injuries, illnesses, deaths • Canada-wide legislation • Information system designed to protect Canadian workers from hazardous materials used in the workplace • Worker’s right to know about workplace hazards
What’s NOT Covered by WHMIS • Consumer restricted products (Hazardous Products Act) • Explosives (Explosives Act) • Cosmetics, drugs, food or devices (Food and Drug Act) • Pest control products (pesticides, herbicides, insecticides, etc Pest Control Products Act) • Radioactive materials (Atomic Energy Control Act) • Wood and products made of wood • Tobacco or products made of tobacco
Main parts of WHMIS • Material Classification and Symbols • Labels • Material Safety Data Sheets (MSDS) • Worker Training & Education
Who’s Responsible • Material Supplier • Employer / Teacher • Employee / Student
Supplier Duties • A supplier of a chemical product must compare and test the product's physical, chemical and toxic properties with a detailed set of WHMIS criteria • Classify products • Label products with a WHMIS label • Prepare and provide customers with MSDS's • Update MSDS's at least every three years
Employer / Teacher Duties • Train students in WHMIS • Train students in safe work practices • Ensure products are labeled with supplier or workplace labels • Provide students with ready access to MSDS's
Employee / Student Duties • Participate in training • Follow prescribed safe work practices (classroom rules) • Wear required protective equipment • Report hazardous situations or violations • Conduct yourself safely – no fooling
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
WHMIS Classification System& Symbols 6 Classes of Chemicals • A Compressed Gas • B Flammable & Combustible Materials • C Oxidizing Materials • D Poisonous and Infectious Materials • E Corrosive Materials • F Dangerously Reactive Materials
WHMIS Classes & Symbols A- Compressed Gas • Materials which are normally gaseous kept in a pressurized container • Risks: • could explode due to pressure • could explode if heated or dropped • hazard from both the force of explosion and the release of contents • Eg. Acetylene, Oxygen, Nitrogen, Aerosol spray can
WHMIS Classes & Symbols B- Flammable & Combustible Material • Flammable = burns at room temperature • Combustible = burns if heated above room temperature • Risks: • may ignite spontaneously • Eg. Gasoline, fuel, chlorine, propane, acetylne, turpentine
WHMIS Classes & Symbols C- Oxidizing Material • Gives off oxygen that can help other materials to burn • Risks: • can cause skin or eye burns • increase fire and explosion hazard • may cause combustibles to explode or react violently • Eg. Bleach, ozone, chlorine, & nitrogen dioxide
WHMIS Classes & Symbols D- Poisonous and Infectious Material • Division D1: Poisonous MaterialToxic Immediate and Severe • Materials causing immediate (acute) and serious toxic effect • Ex. cyanide, chlorine, carbon monoxide
WHMIS Classes & Symbols D- Poisonous and Infectious Material • Division D2: Toxic Material Long Term Concealed • Materials causing other toxic effects. Long term (chronic) effects can be eye and skin irritation, cancer, harm to unborn baby, changes to genes • Ex. asbestos, mercury, lead
WHMIS Classes & Symbols D- Poisonous and Infectious Material • Division D3: Biohazardous Infectious • Infectious material • Eg. live bacteria, infectious material in blood, anthrax, TB
WHMIS Classes & Symbols E- Corrosive Material • Materials which react with metals and living tissue • Risks: • Eye and skin irritation on exposure • Severe burns/tissue damage on longer exposure • Lung damage if inhaled • May cause blindness if eyes contacted • Environmental damage from fumes • Eg. Ammonia, acids, bleach & hydrochloric acid
WHMIS Classes & Symbols F- Dangerously Reactive Material • Materials which may have unexpected reactions • Risks: • May be chemically unstable • May explode if exposed to shock or heat • Can burn or explode if mixed with other chemicals or water • Ex. Nitroglycerine, aluminum chloride
WHIMS Mandatory Labels • Provide info needed to handle and use. • Alert you to hazards, inform you of risks 2 types of labels • Supplier Labels • Workplace Labels
Workplace Labels • Used when products are produced on site • When labels are lost or damaged • When product is put in new container
Material Safety Data Sheet (MSDS) • Lists product Information • Made by the supplier • Read them PRIOR to using the product • Everyone using hazardous materials must have easy access to the Material Safety Data • Know where they are
MSDS are a list of: • Product/Material Information • Hazardous Ingredients • Physical Data • Fire and Explosion Data • Reactivity Data • First Aid Measures • Preventative Measures • Storage and Handling • Spill Clean-up and Waste Disposal • Preparation Date
Material Safety Data Sheet (MSDS) WHMIS requires the supplier to include: • Route of entry into the body • What the short and long term effects are if over-exposed
Chemical Hazards • Health • Contact with many chemicals can result in adverse health effects • The nature and magnitude of toxic effects will depend on many factors including the nature of the substance, route of exposure, magnitude of the dose, duration of exposure, and individual susceptibility
Health Effects of Toxic Substances • Toxic = the ability of a substance to produce an unwanted effect • Hazard = source of danger or injury • Risk = Chance that exposure to a hazard will cause harm
Health Effects of Toxic Substances • Routes of Entry into the body • Ingestion • Absorption (skin, eye) • Inhalation
Personal Protective Equipment • PPE • Safety glasses • Apron • Respirator • Gloves • Hard hat • Safety footwear (steel toe boots) • Hearing Protection
WHMIS – Health Effects • ACUTE - direct threat that shows up almost immediately after exposure such as burns from contact with a corrosive chemical • CHRONIC - usually result from repeated exposure that occurs over months or years and includes cancer and some allergic reactions
