Before being distributed or used, all imported hazardous materials shall be stored in a way that will protect against the unintentional release of the materials to the environment. Where storage is defined as 10% of the reportable quantity or 55 gallons or greater, protective measures shall include:
(1) Segregation of incompatible materials including segregation of all unregulated incompatible materials stored in the same area;
(2) Protection from exposure to weather through storage in an indoor area, including adequate roofs, walls, and floors to prevent rain from reaching PCB’s;
(3) Location in an area that if flooded would pose no risk to populated areas or the water supply;
(4) Protection from all sources of heat, fire hazards, and adequate ventilation;
(5) Bilingual warning signs, in both English and Samoan, indicating the type of substances stored and their hazards shall be posted outside the storage area;
(6) Adequate security, including fences, barriers or other means of preventing unauthorized access, and adequate lighting to promote discovery of spills at night and to prevent spills caused by vandalism;
(7) Containers used to store materials shall be in good condition, shall be compatible with the items being stored, and shall be closed at all times while in storage. Containers used to store materials shall be handled in a way that does not cause the containers to rupture or leak;
(8) Inspections. All storage areas shall be inspected weekly to detect leaking or deteriorating containers and to ensure that all emergency equipment is functioning. All leaking containers and their contents shall be transferred immediately to properly marked non-leaking containers, and spilled or leaked materials cleaned up immediately using absorbents or other adequate means. Inspections shall be conducted by facility personnel whose training has been documented and verified in compliance with sections 24.0811. Inspections shall be documented and records kept on the premises for at least one year.
(9) Labeling in accordance with requirements of USDOT regulations set forth in 49 CFR part 172, which are hereby incorporated by reference.

(A) All facilities where hazardous substances are accumulated or staged shall be off-limits to unauthorized personnel, and appropriate steps shall be taken to protect the public health and safety;

(i) Eyewash station;
(iii) Emergency communication equipment;
(iv) Fire protection as approved by the fire chief;
(v) Personal protection suits, gloves and boots;

(C) Spill prevention equipment. All facilities that accumulate or stage material characterized as hazardous and having the potential to become hazardous waste if released into the environment shall have appropriate containment and spill-prevention controls for preventing a release. Containment devices shall be capable of holding the content of the largest container or 10 percent of all material accumulated or staged in the area, whichever is greater. Such facilities shall be equipped with weather-protection devices that are sufficient for preventing rain or runoff from entering the facility.
(11) A sign or signs bearing the legend “Danger: Unauthorized Personnel Keep Out” shall be posted at each entrance or active part of a facility and at other locations in numbers sufficient to be seen from any approach. The legend shall be written in English and Samoan and shall be legible from a distance of at least 50 feet.
