Hands-on experiences are essential to learning in science class, but safety must be the first concern! The following rules exist for your safety. These rules help to prevent accidents in the lab and allow for more efficient work to occur. Read the entire procedure before you begin. Read chemical labels and MSDS (Material Safety Data Sheets) sheets for chemicals BAKER SAF-T-DATA Guide Listen to all instructions. When in doubt about a procedure, ask me. When first entering the science room, do not touch any equipment, chemicals or other materials until you are instructed to do so. Do only the assigned experiment. NEVER enter the room if unsupervised (you dont see me, dont come in!) Know the location and operation of the following safety equipment: Fire extinguisher Fire blanket Emergency shower Eyewash station Exhaust fan Emergency Safety Kit Gloves Fire extinguishers are distinguished based on the types of fires on which they are effective. These fires are classified by their fuel source and assigned identifying letters as follows: Recommended when handling chemicals and glassware. Know the location of emergency exits and escape routes. To make it easy to exit quickly, do not block walkways with chairs. Protect your clothing and hair from chemicals & sources of heat. Tie back long hair & roll up loose sleeves when working in the lab. Must wear closed-toe shoes on lab days. Report any accident, no matter how minor. Misbehavior CANNOT and WILL NOT be tolerated! Immediately notify your teacher of any unsafe conditions you observe. Work with your group at your station only (that means Group #1 is not across the room with Group #4) Wear safety goggles at ALL times when working on a lab. Do not rub your eyes in lab or touch your face. Food, beverages, chewing gum, cosmetics are NEVER allowed in the lab. Never taste or smell chemicals or touch them with your bare hands. Use a sparker to light a Bunsen burner. Do not use matches. Be sure that all gas valves are turned off and that all hot plates are turned off and unplugged when you leave the lab. Be careful with hot plates, Bunsen burners, & other heat sources. Do not use electrical equipment with frayed or twisted cords or wires. Dont use chipped or cracked glassware. Dont handle broken glass. Report any chemical spills immediately. NEVER take any chemicals out of the lab. Keep your work area clean & tidy. In fairness to others, clean all glassware, lab ware, and equipment at the end of the lab. This includes wiping down your area. Always wash your hands with soap and water before you leave the lab. Looking into the test tube. Always point away TrueFalse Using Glass wear Heating objects Walking in the hallway True False Reaching across equipment (Bunsen burner) Push it under the table Blame the closest person Tell Ms. Gray Wafting Whats wrong? Identify the different safety concerns shown in the picture below. You and your parents must agree to and sign the safety contract in order to participate in lab activities. Failure to comply with safety guidelines may result in your removal from the class and loss of credit for the work that is done in your absence. Remember I must trust you to do the activities, if I can not trust you then you will be given an alternative assignment Practice SAFE Science The answers are Dont eat or drink while in the lab. Dont fool around during a lab. Always wear safety goggles when doing an experiment Always point test tubes and other items away from yourself and others when heating. Keep hair and other flammable objects away from flames. Dont leave a flame unattended.
