Safe Laboratory Practices
To ensure laboratory safety, follow safe laboratory practices, including the following:
- Know about the chemicals and hazards associated with your laboratory.
- Know what to do in different emergency situations.
- Know how to read and interpret MSDS's.
- Wear personal protective equipment, as appropriate.
- Follow safe practices for working with chemicals. (Refer to the Chemical Safety chapter for more
- Ice from a laboratory ice machine should not be used for human consumption.
- Ovens and refrigerators in the laboratory are exclusively for laboratory operations. No food for
consumption is allowed in laboratories.
- Do not wear contact lenses around chemicals, fumes, dust particles, or other hazardous materials.
- Protect unattended operations from utility failures and other potential problems that could lead to
overheating or other hazardous events.
- Avoid working alone in a laboratory.
- Avoid producing aerosols.
- Use extreme care when working with needles, blades, and glass.
- Do not eat, drink, or use tobacco products in the laboratory.
- Do not mouth pipet.
- Clean contaminated equipment and spills immediately. Avoid contaminating equipment with mercury.
Clean mercury spills immediately. (Chronic exposure to mercury can result from a few drops left
- Do not allow children in the laboratory. (It is a violation of state law for a child to be unattended in a
place that presents a risk of harm.)
- Keep laboratory doors closed.
- Decontaminate all affected equipment.
- Avoid using dry ice in enclosed areas. (Dry ice can produce elevated carbon dioxide levels.)
- Dry ice mixed with isopropanol or ethanol may cause frostbite.
- Hallways, corridors, and exit ways must be kept clear. Do not locate (even temporarily) laboratory
equipment or supplies in these areas.
Never underestimate the hazards associated with a laboratory. If you are unsure about what you are doing, get assistance. Do not use unfamiliar chemicals, equipment, or procedures alone.
