Safety In the Science Lab
Rules and Symbols
Millbrook Middle Junior High 1

2. Safety First Safety is my #1 priority in the science lab.
Science is a hands-on laboratory class.
You will be doing many laboratory activities, which require the use of hazardous chemicals and expensive lab equipment.
To ensure a safe science classroom, a list of rules has been developed and provided to you in your student safety contract.
These rules must be followed at all times.
A signed lab safety contract and a passing grade on the safety test is required to participate in labs. 2

3. General Safety Guidelines
Be Responsible at All Times. No horseplay, practical jokes, pranks, etc.
Follow all instructions carefully.
Do not play with lab equipment until instructed to do so.
Verbal & written directions. If you don’t understand ask for help.
Do not do any experiments without teacher approval.
Food, drink, and gum are not allowed in the science classroom.
Stay at you lab station unless directed to move. 3

4. General Safety Guidelines
Keep the science room clean and organized.
Notify the teacher immediately of any accidents or unsafe conditions in the science classroom!
