5 General All instructions, written and verbal, about laboratory procedures MUST be followed. Know the location and proper use of safety equipment. Equipment or supplies should NOT be handled without teacher permission. UNAUTHORIZED EXPERIMENTS ARE FORBIDDEN. Act responsibly. Failure to do so will result in your permanent removal from science labs. (c) McGraw Hill Ryerson 2007

6 General Safety equipment, including goggles and lab aprons, must be worn during every lab. Hair and loose clothing must be tied back. Each lab station must be kept clean and tidy at all times. There is absolutely NO FOOD, DRINK, or GUM allowed during labs. (c) McGraw Hill Ryerson 2007

7 Glassware Never use cracked glassware. Use clean glassware.

8 Chemicals Wash any affected areas immediately with water and inform your teacher. If you get anything in your eyes, wash them continuously for 15 minutes. Never smell a substance directly, waft the fumes towards your nose. Hold containers away from face when pouring liquids. Never put any chemical back into its original container. Only put chemicals down the sink or into the garbage with permission.

9 Hot Plates Use heatproof containers only.
Do not allow a container to boil dry. Be careful with a hot plate that looks as though it has cooled down. (c) McGraw Hill Ryerson 2007

10 Open Flames Wear protective gear. Tie back long hair and loose clothing. Handle hot objects carefully (they may look cool). Point the open end of container that is being heated away from yourself and others. Turn off gas valves or hot plates as soon as you are finished using them. Apply cold water to burns.

11 Electrical Equipment Make sure your hands are dry when touching electrical cords, plugs or sockets. Pull the plug, not the cord. Report damaged equipment to your teacher. Place electrical cords where people will not trip over them. (c) McGraw Hill Ryerson 2007
