Past incidents involving hazardous waste found in ordinary trash containers indicate that waste procedures need to be reinforced with lab staffs. Review the protocols for disposal of hazardous chemicals, biological materials, radioactive materials, needles, broken glass, and other hazardous items including gloves and bench papers. Housekeeping is ever-important. Getting rid of old unused chemicals makes more space for other things and creates a safer environment. Clutter on benches, in hoods, and in storage cabinets invites trouble.
Unclean surfaces breed contamination and infection.
Personal hygiene is very important for anyone working in a laboratory. Hand washing is known to be one of the best ways to avoid infection and contamination and is one of the most neglected. Wash hands frequently, especially after removing gloves and before leaving the laboratory. Also have lab coats and clothing cleaned regularly. Wearing contaminated clothing is like wearing a toxic shroud.
