SAFE HANDLING OF CHEMICALS CONCEPTS EXPLORED IN THIS LESSON 1) Hazardous Safety Symbols 2) Hazardous Household Product Symbols 3) WHMIS HAZARDOUS SAFETY SYMBOLS Safety Symbols: have been developed to warn users of the hazards _________ associated with different products. TWO TYPES of Safety Symbols 1) HHPS 2) WHMIS 2015 “Hazardous Household “Workplace Hazardous Product Symbol” Materials Information System” household Found on _________ workplace Found on _________ products – mostly products – mostly _______. cleaners _______. cleaners HAZARDOUS HOUSEHOLD PRODUCT SYMBOLS There are ___ 12 HHPS representing different types and levels of hazard. 4 different types of hazards. FOUR TYPES: There are __ poisonous explosive corrosive flammable 3 levels of hazards, each more harmful THREE LEVELS: There are __ than the previous. more harmful caution warning danger colour yellow orange red # of sides 3 sides 4 sides 8 sides HAZARDOUS HOUSEHOLD PRODUCT SYMBOLS Combining the ____ type and ____ level of hazard creates a HHPS. caution warning danger poison poison poison warning danger caution corrosive explosive flammable HAZARDOUS HOUSEHOLD PRODUCT SYMBOLS Label each safety symbol by LEVEL and TYPE of hazard. danger caution warning danger poisonous explosive poisonous flammable caution warning danger caution corrosive explosive explosive poisonous caution danger warning warning flammable corrosive flammable corrosive WHMIS WHAT DOES WHMIS 2015 STAND FOR? Workplace H azardous M aterials Information S ystem WHAT IS THE PURPOSE OF WHMIS? It is a national system for providing information on the safe handling and use of hazardous materials in the workplace.  WHMIS 2015 WHMIS 2015 has adopted Globally Harmonized System of Classification and Labelling Chemicals (GHS). The intention of using GHS as Canada’s hazard communication system to be more aligned with Canada’s trading partners.  WORKPLACE HAZARDOUS MATERIALS INFORMATION SYSTEMS SYMBOLS There are __ 9WHMIS symbols. Each WHMIS symbol has a ________ for its border, except for diamond one. long term biohazardous corrosive acute toxicity acute toxicity health and infectious materials (harmful) (fatal) hazards flammable oxidizing gases under self-reactive materials materials pressure materials  Gases Under Pressure Hazards Precautions Contents under high Ensure container is pressure and could always secured and kept explode if dropped or away from heat sources heated Examples Oxygen, acetylene, propane and aerosol cans;  Flammable Material Hazards Precautions Materials will continue to Store in designated areas burn after being exposed and avoid heating and to a flame or other ignition ignition sources sources Examples Gasoline, propane, acetylene Propane explosion  Oxidizing Material Hazards Precautions Materials which can Store away from cause other materials to combustibles and in burn; containers that do not rust Can cause skin and eye Wear protective clothing burns (gloves & goggles) Examples Bleach, ozone, oxygen;  Acute Toxicity (fatal) Hazards Precautions Poisons – fatal if ingested Wear protective clothing or inhaled (eye, face, gloves) Small volumes have a Work in a well ventilated toxic effect area Examples Chlorine gas, carbon monoxide, cyanides  Acute Toxicity (harmful) Hazards Precautions Causes skin and eye Wear protective clothing irritation, skin sensitivity, (eye, face, gloves) specific target organ Work in a well ventilated toxicity from single area exposure. Examples isopropyl alcohol isopropyl alcohol, (rubbing alcohol) acetone, potassium iodide  Long Term Health Hazards Hazards Precautions Materials that have Wear protective clothing harmful effects after long (eye, face, gloves) term or repeated Work in a well ventilated exposure (cancer, area infertility, allergies, death) Examples asbestos, arsenic, mercury asbestos  Biohazardous & Infectious Hazards Precautions Infectious agents or a Special training required biological toxin causing a to work in designated serious disease or death areas Examples Botox, HIV, Ebola virus, salmonella, E. coli, TB;  Corrosive Hazards Precautions Materials which react with Wear protective clothing living tissue and metals; (eye, face, gloves) Severe burns/ tissue Work in a well ventilated damage area Examples Acids, bleach;  Self-reactive Materials Hazards Precautions Materials which may have Handle with care avoiding unexpected reactions vibration, shocks and (explode when shaken) sudden changes in temperature Examples TNT, nitroglycerin, sodium metal, nitrogen triiodide; Example of Self-Reactive Materials Click Here! - Reaction of Nitrogen Triiodide  th The 10 GHS Symbol WHMIS 2015 does not Hazardous to the incorporate the GHS Aquatic Environment Environmental Hazard Class.
