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
       information.)
  • 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
       uncleaned.)
  • 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.

¬°IMPORTANT!
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.
