Laboratory Safety

Lab Housekeeping

Housekeeping is an important element to a laboratory safety program. A clean, well-maintained lab improves safety by preventing accidents and can enhance the overall efficiency of the work being performed. The following laboratory housekeeping guidelines should be followed:

• All doorways and hallways must be free of obstructions to allow clear visibility and exit.
  • The laboratory should be uncluttered without excessive storage of materials that could cause or support a fire (e.g., paper, cardboard, flammable liquids, etc.).
  • Fire protection sprinklers must be unobstructed; a minimum of 18 inches of clearance is required below the sprinkler head. If the laboratory does not have fire protection sprinklers, there must be a minimum of 24 inches of clearance below the ceiling.
  • Do not store items that block fire extinguishers, eyewash and safety shower stations or in front of electrical boxes/panels in the lab.
• All work surfaces should be kept as clean as possible. All potentially chemically contaminated work area surfaces (e.g., chemical fume hood deck, countertops) should be cleaned routinely (e.g. daily, weekly)
  • Ensure that all waste (e.g., trash, chemically contaminated debris waste, etc.) is placed in the appropriate containers. Do not overfill waste containers.
  • Chemical containers must be clean, properly labeled and returned to storage upon completion or usage. Avoid storing liquids above eye level.
  • Never pour chemical waste into sink drains or rubbish bins unless instructed to and as permitted by Safety Data Sheets (SDS).
• All equipment should be cleaned and returned to storage after each use.
• Do not store heavy or frequently used items on top shelves. Locate items used daily close to the work area.
