Laboratory Housekeeping

As you walk through a well-kept laboratory, you should note a clean and orderly workplace.

General

• Floors should be free of hazards. Never leave carelessly discarded objects, dropped objects, or spilled material on the floor.
• Always keep tables, chemical hoods, floors, aisles, and desks clear of all material not being used.
• There should always be two clear passageways to exits.
• There should always be clear space around safety showers or eyewashes, fire extinguishers, and electrical controls.
• Sink traps and floor drain traps should be filled with water at all times to prevent the escape of sewer gases into the laboratories.
• Any frequently used bench apparatus should be kept well away from any edges and secured whenever possible.
• Clean work areas upon completion of an experiment or at the end of each day.
• Bench tops and bench liners should be free of visible contamination.
• Reduce the risk of slips, trips, and falls by cleaning up liquid or solid spills immediately, keeping doors and drawers closed and passageways clear of obstructions.

Storage

• Sharp or pointed tools should be properly sheathed or stored.
• Clothing should be hung in proper locations and not draped over equipment or benches.
• Less commonly used equipment should be kept in storage.
• Do not store chemical containers on the floor.
• Do not store excess cardboard boxes, equipment boxes, Styrofoam, etc. under lab benches, on shelves, or above shelves/cabinets throughout the lab. This can be a safety as well as a fire hazard.
