All students for all classes are required to sign the following safety contract. This will be done in class.
Secondary Science Safety Contract
1. Written and verbal instructions concerning procedures and/or precautions are given for my protection. I will read and listen carefully, and follow all directions.
2. Experiments done in class are for instruction. They are planned in order to teach an idea. I will perform only authorized experiments.
3. I will handle only those chemicals or equipment for which I have received instructions or training. No control for gas, air, or water is to be turned on except for lab work. Electrical outlets are only to be used for electrical plug-ins— other inserts are dangerous.
4. Tasting, smelling, or mixing unknown substances can be very dangerous. I will not do so unless instructed to do so in a planned, approved experiment, with proper techniques.
5. Chemicals are labeled to identify them. I will always carefully read the label to be sure I am using the correct substance. To avoid contaminating chemicals, I will not return used or unused chemicals to reagent containers. I will dispose of chemicals as my teacher directs and never mix chemicals in the sink drain.
6. Horseplay and practical jokes in the science classroom are dangerous and can be expensive. I will practice safe conduct in the classroom.
7. Fire is dangerous and care must be taken when working with it. I will not reach across a flame or bring a flammable substance near flames. I will confine long hair and loose clothing to prevent it from igniting. Know where the fire extinguisher and fire blanket are located and how and when to use them. All fire must be extinguished, gas off, and materials capped, before departing from the classroom for a fire drill or other school activity. I will not carry any lighted alcohol lamps or splints away from the lab station. No aerosol spray is ever to be used in a science lab by a student unless directed by the teacher. Alcohol burners are to be lit only while in use and must not be refueled when fire is present.
8. Safety equipment (eyewash, shower, first-aid kit) is provided in the science classroom in case of emergency. I know how and when to use this equipment.
9. Hot materials, such as glassware, hot plates, Bunsen burners, and chemicals can cause serious burns. I will be extremely careful when working with these to prevent injury to myself and others. I will be sure that the open end of a test tube points away from everyone while the test tube is being heated or shaken. I will always heat test tubes evenly and use boiling chips to prevent liquid “shooting.”
10. Broken glass is dangerous. I will use a broom and dustpan to immediately pick up all broken glass and place it in the broken glass container.
11. Safety goggles are required by law [Minnesota Statutes, Section 126.20 (Ex1967, C14, S1-6)]. Goggles must be worn covering the eyes during all activities using fire or glassware; mixing, handling or heating chemicals; chipping rock; or whenever danger exists to the eyes. I will wear my safety goggles unless permission to remove them is granted by the teacher. I will also wear other necessary apparel required for specific work, i.e. apron, gloves, shoes, etc.
12. If an incident should occur that results in injury to myself or others in the science classroom or damage to equipment, I will immediately report it to my teacher, no matter how minor the injury or damage may appear. Spilled mercury from broken thermometers or other sources must be avoided. Chemical spills on skin or clothes should be flushed with water immediately. All accidents, cuts, or spilled chemicals, should be reported immediately to the instructor.
13. I will not eat, drink, or chew gum in the science classroom. I will always wash my hands carefully after handling chemicals, specimens, or animals. Water is allowed in the classroom only if in a closable container. NO outside food or liquid is allowed in the lab (including water bottles).
14. I will use proper techniques and be careful with sharp instruments.
15. It is important to know the exits to be used in case of emergencies. Students must not sit in the aisles which might prevent emergency exit from the classroom. Likewise, projects, materials, or equipment must not be stored so as to slow room evacuation. I am familiar with the exits and the appropriate action to take when the emergency signal is heard.
