Safety in the Science Lab Video 2 Rules and Behaviours 1. Wear appropriate PPE for the lab 2. No food in the Science lab 3. Know the location of all safety equipment, and fire exits. 4. Follow the teachers instructions. 5. Long hair should be tied back and no open toed shoes. 6. Waft orders at a forearms links away 7. Pour excess material in the designated waste receptacle. 8. Clean the lab bench when you're done with it. Video 1 1.No horse play 2. Know the lab procedure before starting an experiment 3. Never reach over an open flame. 4. Don't mix flammable materials with a fire 5. Don't put items that are on fire in the trash. ( They can set the trash on fire.) 6. When heating a substance in a tube, do not look down the tube or pointed in the direction of anyone. 7. When using a Bunsen burner, make sure that the flame is defined and blue so it can heat the material evenly and properly. Chemicals 8. Never touch or smell unknown substances. Electricity 9. Never use equipment with freight cords or loose or broken wires. 10. Never touch electrical equipment with wet hands or use them near water. 11. Turn off the power switch of electrical equipment before plugging it into an outlet 12. Never pull plugs out of an outlet by its wire. 13. Be familiar with the operating instructions before using electrical equipment Equipment 14. Report all broken and shift glass to the teacher and don't pick it up with bare hands Be Science Ready ​ Do not wear contact lenses Follow instructions ​ Wear eye protection Act responsibly Know the Material, Safety, Data, Sheet The three stages of being in a safe lab are BFA Labelling Hazardous Materials Global Harmonized System GHS Workplace Hazardous Materials Information System WHMIS Levels of Hazard Blue = Health Red = Fire Yellow = Reactivity White = Other 1988 hazards are directly on the label 2015 hazards are on the Safety Data Sheet (uses hazard categories) 1988 4—----------3—-----------2—-----------1 2015 Most to least 1—-----1a—-------1b—------2—------3 Personal Protective Equipment Goggles Gloves Lab Coat Face Shield Fume Hood HHPS Hazardous Household Product Symbols *Different companies use different symbols PH SCALE 1 ←—--------------------------|-------------------------->14 acidic 7 basic Corrosive Sodioum hydroxide Na0H Potassium hydroxide KoH Flammable Alchohol Ethanol Mathanol Propane Butane Poisonous Petroleum distillates WHMIS : Is a federal and provincial legislative response to the Canadian workers rights to know about the safety of the materials that they use in the workplace, their right to participate in training, and their right to refuse unsafe work. WHMIS 1988 was modified to include the Globally Harmonized System (of Classification and Labelling of Chemicals) because of changes of the regulations in the HPA (hazardous products act) This helped with: More consistent hazard info Improved emergency response Trading Safer handling Reduced Supplier Cost WHMIS 1988 were called “controlled products” WHMIS 2015 were called “hazardous products” Hazard Groups WHMIS 2015 split the symbols into hazard groups. Physical hazard classes include flammable liquids, gases under pressure and oxidizing solids Health classes include acute toxicity, skin care, or irritation, and carcinogenicity. Labels on Hazardous Products What you would find on a 2015 WHMIS label P.P.S.S.P.H.S. → Please prevent spills safe practice helps save Each letter stands for: Please prevent spills safe practice helps save P-Product Identifier P-Precautionary Statement S-Supplier Identifier S-Signal Word P-Pictogram H-Hazard Statement S-Supplemental Information The Supplier Label The labels on chemicals from a laboratory supply house which weigh less than 10 KG must disclose a product identifier, a supplier identifier, WHMIS 2015 pictograms, alert words, precautionary statements, hazard statements, etc. The Laboratory Label If chemicals are removed from the original container and transferred to another, the transfer container must identify its contents. Workplace Label If material is transferred within a laboratory, the transfer container must carry a workplace label that includes a chemical identifier, instructions and a reference to the SDS. SDS : Is usually prepared by the product manufacturer or supplier the SDS provides more detailed information than the product label. Unlike its predecessor, the material Safety data sheet or MSDS the SDS does not expire. The supplier must update the SDS when new information and precautions about the material become known. 1.​ HPA - Hazardous Products Act 2.​ GHS - Global Harmonized System 3.​ WHMIS - Workplace Hazardous Materials Information System 4.​ BFA - Be Science Ready, Follow Instructions, Act Responsibly 5.​ SDS - Safety Data Sheet 6.​ MSDS - Material Safety Data Sheet (predecessor to SDS)  7.​ PPE - Personal Protective Equipment 8.​ HHPS - Hazardous Household Product Symbols 9.
