VCS Science Handbook Section 4.4

  • 4.4.0 Laboratory Safety Regulations for Science Students
    • In order to decrease the chances of any accidents occurring, all students, teachers, and visitors to science laboratories are required to follow the safety procedures listed below:
    • 4.4.1 Prepare for laboratory work
      • • Prepare for each laboratory activity by reading all procedures before class. Make note of any deviations announced by the teacher.
      • • Do not bring food or beverages into the laboratory.
      • • Know the location of the emergency, first aid, and fire-fighting equipment. Know the proper fire drill procedure and know where to get help quickly.
      • • Know how to use the safety shower, eye wash, fire blanket, and first aid kit.
      • • Keep your work area clean and tidy. Keep it free of apparel, books, and other clutter.
    • 4.4.2 Follow instructions
      • • Follow all written and verbal instructions carefully.
      • • Only perform laboratory activities where the teacher has given instructions and permission.
      • • Use only materials and equipment authorized by the teacher.
      • • Do not enter laboratory storage space unless directly instructed to do so.
    • 4.4.3 Dress for laboratory work
      • • Wear chemical goggles when working in the laboratory and using chemicals. Safety goggles may be required in other science labs when chemicals are not being used.
      • • Wear lab coats or aprons.
      • • Wear gloves when using chemicals that irritate or can be absorbed through skin.
      • • Roll long sleeves above the wrist. Remove ties, coats, and sweaters. Tie back long hair.
      • • Do not wear long, hanging necklaces, bulky jewelry, and excessive and bulky clothing. Wear closed-toed shoes.
    • 4.4.4 Avoid contact with chemicals
      • • Never taste, smell, or touch chemicals unless specifically instructed to do so.
      • • When noting odors or fumes, use a wafting motion of the hand. Never put a bottle to your nose and breath deeply or “sniff.”
      • • Never allow the open end of a heated test tube to be pointed toward anyone.
    • 4.4.5 Avoid Hazards
      • • Do not bring any substance into contact with a flame or other heat source unless specifically instructed to do so.
      • • Use caution when handling hot glassware.
      • • Always twist, never push glass tubing into stopper holes. Lubricate tubing with glycerin.
      • • Never pour water into acid. Correctly dilute acid by pouring it into water.
      • • Avoid direct viewing of the sun and infrared, ultraviolet, or laser light.
      • • Do not engage in horseplay, running, pushing, shoving, or practical jokes.
    • 4.4.6 Clean up
      • • Consult teacher for proper disposal of chemicals.
      • • Place solid waste in designated receptacles. Do not discard solids in sinks.
      • • Clean and wipe dry all desks, tables, and laboratory work areas at the end of each laboratory activity.
      • • Wash your hands thoroughly with soap and water at the end of each laboratory period.
    • 4.4.7 In case of accident
      • • Report all accidents to the teacher immediately, no matter how minor.
      • • Place broken glass in the labeled sharps box. Never handle broken glass with your bare hands.
      • • Wash all acids and bases from your skin immediately with plenty of running water.
      • • If chemicals get in your eyes, wash them for at least 15 minutes with an eyewash.
