Staying Safe while Conducting Hands-On Science
Never change wiring with circuit plugged into power source. Never plug leads into power source unless they are connected to an established circuit. Avoid contacting circuits with wet hands or wet materials. Wet cells should be placed on a piece of non-conducting material. Check circuits for proper grounding with respect to the power source. Do not insert another fuse of larger capacity if an instrument keeps blowing fuses - this is a symptom requiring expert repairs. If a fuse blows, find the cause of the problem before putting in another one.
By the Ohio Fire Code, extension cords must be connected to a power strip equipped with a fuse. Do not use or store highly flammable solvents near electrical equipment. Multi-strip outlets cube taps should not be used in place of permanently installed receptacles. If additional outlets are required have them installed by an electrician. Keep access to electrical panels and disconnect switches clear and unobstructed. Static Electricity and Spark Hazards: Some common potential sources of sparks are: The making and braking of an electrical circuit when the circuit is energized.

Do not sit or lean on a lab table. Be sure to sit in the chairs or stools provided by the lab or remain standing. The weight on the table could cause it to tilt and spill or break lab materials. Know the location of safety equipment. Before the lab begins, be sure to know where the safety equipment is located. You should know the location of the fire extinguisher, eye washing station, and first aid kit. Know what to do after an accident. Rinse your eyes or skin immediately if you come in contact with a toxic chemical. Notify a teacher or other adult if you have an emergency.
If you have a spill, notify your teacher before trying to clean it up. Some chemicals have to be cleaned up following special protocols.
Touching it can result in heavy metal poisoning. Avoid working alone in the lab. It is best practice to have at least two people in a lab during an experiment.

This is especially important if you are dealing with toxic chemicals or fire. Make sure there is someone to help you in case you get injured before starting an experiment with hazardous materials. Avoid running, pushing, goofing off, or playing pranks while in the lab.

Be aware of your surroundings and walk through the lab with care. These kinds of careless behaviors will result in spills and accidents in a lab.
School Lab Safety Tips
Always keep two hands on lab materials. You need a good hold on lab materials while you are carrying them through the room. There is always a chance that someone might accidentally bump you, or that one hand might slip. Try to carry any containers with one hand on the bottom and one on the top or side. Listen to all of the instructions from the teacher before beginning the experiment.
If you are following a book or manual, be sure to read the instructions thoroughly. Do not skip steps. Do not work ahead unless you have been instructed to do so.
Electrical Safety in the Lab | Lab Manager
Handle instruments with care. Take care of the lab equipment during the experiment as well as during clean up. Report any chips or cracks glass equipment as they could cause injury. Ask for guidance before using new equipment. If you are unsure how to handle a piece of lab equipment, ask your teacher or classmate for help. Do not assume that you understand how to use the equipment.
Never taste or smell chemicals. Many materials in a lab are very toxic.
Never eat, drink, or smell any materials during an experiment.
