Lab Safety Guide
Follow All Safety Procedures
- Always wear chemical splash goggles for eye protection when working with chemicals.
- When pouring large quantities of hazardous chemicals, in addition to goggles, wear a face shield large enough to protect your ears and neck as well as your face.
- Always wear gloves when handling chemicals. Select the glove material based on compatibility with the chemicals you may contact.
- Always wear appropriate clothing: chemically resistant lab coats or aprons are recommended.
- Do not wear shorts or miniskirts (anything that would leave your legs bare and unprotected). Do not wear high-heeled shoes, open-toed/heeled shoes, sandals or shoes made of woven materials. Confine long hair and loose clothing.
- Do not work with hazardous chemicals or processes when alone in the laboratory. An instructor must supervise undergraduate students at all times.
- Always use chemicals with adequate ventilation or in a chemical fume hood. Do not allow the release of toxic substances in cold rooms or warm rooms, since these areas have contained, re-circulated air.
- Use chemicals only as directed and for their intended purpose.
- Never use mouth suction to fill a pipette or siphon. Use a pipette bulb or other suitable device.
- Handle needles, syringes and other sharps carefully. Use self-sheathing needles or needless systems whenever possible. Dispose of all sharps in an appropriate sharps container.
- Do not dispose of chemicals down the drain. Most chemicals must be disposed of as hazardous waste.
- Compressed gas cylinders must be secured to prevent them from being knocked over. Cylinders must be capped when the regulator is removed or not in use.
- Inspect the lab weekly for hazardous conditions.
- Shield or wrap pressurized or evacuated equipment (dewars & vacuum flasks).
