Storage of Hazardous Chemicals
(1)Store hazardous chemicals:
(a)Separately, to prevent hazardous reactions. Label storage areas by category to prevent the mixing of incompatible types of chemicals. (Examples of categories include: flammable liquids, acids, bases oxidizers.)
(b)In conformance with manufacturer’s instructions on the label or Safety Data Sheet (SDS) to prevent conditions that could adversely affect container integrity or product stability.
(c)Separate from food and personal items to prevent contamination.
(d)Separate from sources of ignition. In locations where flammable vapors may be present, take precautions to prevent fires by eliminating or controlling sources of ignition.
(2)Ventilate storage areas, as needed to keep air contaminants below 25 percent of the lower explosive limit (LEL).
(3)Provide natural or artificial lighting equal to 20 foot-candles for safe entry into the storage area and to permit identification of chemical containers.
(4)Storage, handling, and removal of hazardous chemical containers must not cause hazards to workers.
(5)The following additional requirements apply where storing Restricted Use Pesticides:
(a)Lock the storage area to prevent access by unauthorized persons.
(b)Provide separate sections within the storage area for each category of pesticide product. (Examples include: insecticides, herbicides, fungicides, fumigants.) Label these areas by general category.
(c)Floors and shelves must be constructed of a chemically-resistant material; or coated, sealed, or provided with secondary containment that prevents the absorption of the hazardous chemicals.
(d)When the storage area contains enough chemical that a leak or spill could cause the material to leave the confines of the building, there must be sufficient containment or other means to contain any leaks or spills within the storage area.
