Dispose of used chemicals, matches, and living or preserved specimens only as directed by the teacher Turn of all electrical equipment, water, and gas when it is not in use, especially at the of the lab period Know the location and how to operate all safety equipment in the classroom, including fire extinguisher, fire blankets, sand, safety showers, eyewash fountains, and first-aid kit. Do not use the sink to discard matches, filter paper, or other solid or slightly soluble materials.

4. LABORATORY APPAREL PRECAUTIONS Do not wear loose-fitting sleeves, bulky outerwear, or open-toe shoes Tie back long hair Wear safety goggles when using chemicals, hot liquids, lab burners or hot plates. Wear plastic gloves when working with preserved specimens or with poisonous, corrosive, or irritating chemicals.

ACCIDENT PROCEDURES Report all accidents or injuries and all breakage or spills, no matter how minor, to the teacher If a chemical spills on your skin or clothing, wash it off immediately with plenty of cool water and notify the teacher. If a chemical gets into your eyes or on your face, wash immediately at the eyewash fountain with plenty of water. Wash for at least 15 minutes and notify the teacher. Clean up all spills immediately Use a dustpan and a brush to pick up broken glass.

6. WHMIS Workplace Hazardous Materials Information Systems The 3 components to the WHMIS system are: 1.MSDS 2.Worker Education 3.Labels on all Products

7. MSDS Stored in binders in lab areas All known chemicals 8 sections (name, ingredients, physical data, fire hazards, reactivity data, toxicological properties, preventive measures, first aid measures)

8. WHMIS SYMBOLS

9. WHMIS Labels 1.Compressed Gas ex. Helium, propane 2.Flammable/Combustible ex: methane gas, acetone 3.Oxidizing Material ex: Chromic Acid 4.Poisonous Infectious (Immediate & Serious Toxic Effects) ex: cyanide 5.Poisonous Infectious (Other Toxic Effects) ex: mercury, lead 6.Biohazardous Infectious ex: needles 7.Corrosive Materials ex: degreaser 8.Dangerously Reactive ex: pure sodium

10. HHPS Symbols Hazardous Household Product Symbols HOUSEHOLD! Levels of Severity (Danger, Warning and Caution)

11. Fire Safety P-A-S-S LHHS extinguishers (AB C type) Class A – combustible materials that leave coals or ash such as paper, wood, cloth Class B – flammable liquids such as gas or solvents Class C – live electrical equipment as appliances, electrical lab equipment, photocopiers, computers, etc..

12. Precautions related to Dissections: When working with preserved specimens be in a well- ventilated area Where vinyl gloves at all times To reduce the irritating effects of chemical preservatives, rinse specimen under running water to eliminate excess and dilute what remains Review procedure for cuts and punctures from dissecting tools When cleaning dissecting instruments, hold sharp edges away from you. Always ask the teacher re: proper disposal of specimens.
