Basic Lab Safety Rules

If you are student in the Dept. of Biological Sciences you are no stranger to the basic safety rules in the laboratory. Below is what we would consider the minimum rules to observe when you walk into any laboratory on campus:

• You must always wear appropriate eye protection whenever anyone is working with hazardous chemicals or processes in the lab.
• Wear fully enclosed shoes (e.g. sandals and clogs are not appropriate footwear). A lab coat or lab apron must be worn while you are working with hazardous chemicals in the laboratory. Wear gloves that are resistant to permeation by chemicals that can cause serious or irreversible damage upon skin contact. Confine loose hair and clothing.
• It is recommended you report a significant physical or medical condition -- for example, pregnancy or chemical allergy -- to your advisor or P.I. for your protection, although you are not required to share this information.
• If you injure yourself -- for example, if you cut, burn, or spill a harmful chemical on yourself -- tell your P.I. or advisor at once.
• Make sure you understand and follow all directions for each procedure, including the appropriate safety precautions.
• Learn the locations of safety equipment before you begin working -- safety showers, eye wash fountains, fire blankets and substances for neutralizing acid spills. Locations of showers and eye wash fountains are especially important because you may need one suddenly. Use of fire extinguishers is limited to faculty; in case of fire, leave the room.
• If you leave the lab for any reason during an experiment, you must secure your experiment and work area before leaving. Turn off all heat sources.
• Keep your equipment locker and work area neat. Clutter creates accidents.
• Dispose of waste chemicals according to directions stated in your lab procedure or given by your P.I./advisor. Do not return unused chemicals to their original containers.
• Clean up spilled chemicals or broken glass immediately. Dispose of broken glass in designated glass disposal boxes. If you break a thermometer containing mercury, tell your instructor immediately so it can be cleaned up.
• Wash your hands before leaving the lab.
• Do not work alone in any lab. Do not perform unauthorized experiments. These rules also apply to project students.
• Do not eat or drink in the lab. Do not place food or drink containers, including water bottles, on bench top.

How to Prevent Lab Goggles From Fogging

• Use commercial anti-fog sprays and pre-treated wipes.
• Let them acclimate to the temperature of the room for a few minutes before putting them on.
• Adjusting the strap to allow for slight air flow around the edges, without compromising the protective barrier, can significantly reduce condensation.
• A small drop of liquid dish soap can be lightly rubbed onto the inside of the lens. After coating the surface, use a microfiber cloth to gently buff the lens until it appears clear, leaving a barely perceptible residue.
  • This thin film performs the anti-fog action, forcing the water to sheet instead of bead.
