How Is Your Housekeeping?
OSHA standards state “all places of employment, passageways, storerooms and service rooms shall be kept clear and orderly and in sanitary condition.” Common sense says good housekeeping is an attitude and the cornerstone of any good safety program. Safety inspectors check housecleaning practices first. A clean lab is a safer lab.
