Protective clothing and equipment must be worn. Heavy-duty rubber apron, rubber gloves,
safety splash goggles and/or face shield are required when potential exists for contact with
wastewater or contaminated surfaces. Wastewater and surfaces may be contaminated with
pathogenic microorganisms, bacteria or viruses, which present a risk of serious illness or
death to personnel.
Never mix chemicals or detergent and sanitizing solutions. This may produce highly toxic or
poisonous gas that can cause serious illness or death to personnel.
Proper cleaning of the latrine components is an integral part of maintenance. It can help prevent possible
problems in the future, so make it a habit to clean all latrine components on a daily basis. Clean the
commodes, urinal, floor mat, aisle floor, and sink stand with general-purpose detergent or a chlorine-
cleaning agent periodically. Clean latrine components as described in the separate technical manuals
