Safety Regulations for Science Students
While working in the science laboratory, you will have certain important responsibilities that do not apply to other classrooms. You will be working with materials and apparatus which, if handled carelessly or improperly, have the potential to cause injury or discomfort to someone else as well as yourself.
A science laboratory can be a safe place in which to work if you, the student, are foresighted, alert, and cautious. Violating any of the following regulations will result in you being suspended from class or permanently removed from the class. The following practices will be followed:
· Matches, litmus paper, wooden splints, toothpicks, and so on
· Broken and waste glass
· Rags, paper towels, or other absorbent materials used in the cleanup of flammable solids or liquids
· Hazardous/toxic liquids and solids
32. Students are not permitted in laboratory storage rooms or teachers' workrooms without the approval of the teacher.
33. To cut small diameter glass tubing, use a file or tubing cutter to make a deep scratch. Wrap the tubing in a paper towel before breaking the glass away from you with your thumbs. Fire polish all ends.
34. Hot and cold glass has the same visual appearance. Determine whether an object is hot by bringing the back of your hand close to the object.
35. Match hole sizes and tubing when inserting glass tubing into a stopper. If necessary, expand the hole first by using an appropriate size cork borer. Lubricate the stopper hole and glass tubing with water or glycerin to ease insertion, using towels to protect the hand. Carefully twist (never push) glass tubing into stopper holes.
36. Remove all broken glass from the work area or floor as soon as possible. Never handle broken glass with bare hands; use a counter brush and dustpan.
37. Report broken glassware, including thermometers, to the instructor immediately.
38. Operate electrical equipment only in a dry area and with dry hands.
39. When removing an electrical plug from its socket, pull the plug, not the electrical cord.
40. Treat all animals in the science laboratory humanely; that is, with respect and consideration for their care.
41. Always approach laboratory experiences in a serious and courteous manner.
42. Always clean the laboratory area before leaving.
43. Students and teacher wash hands with soap and water before leaving the laboratory area.
44. When heating volatile or flammable materials, use a water bath; that is, heat the materials in or over heated water, using a hot plate to heat the water. Extinguish all open flames.
45. Exercise caution in using scissors, scalpels, dissecting needles, and other sharp‑edged instruments. Pass them with handles extended when handing them to other persons.
46. Wash all sharp‑edged and pointed instruments separately from other equipment.
47. Use great care when working with ether or other volatile liquids. Windows and doors should be opened for greatest possible ventilation. Be sure that caps or lids of containers used for chemicals are securely closed.
The following actions will result in both immediate removal from class as well as being dropped from the class:
Lifting the plastic cover and /or pushing the “Big Red Button” in the front of the classroom.
Misuse of safety equipment including, but not limited to
Removal of any materials or equipment from the classroom or laboratory
Vandalizing school equipment or furniture.
Endangering or causing harm to others.
Note: Persistent or willful violation of the regulations will result in the loss of laboratory privileges and possible dismissal from the class. Please see the "Student Safety Contract" on the following page.
