Apply safe chemical storage and segregation practices for a pool service company's chemical inventory

Steps

1. Classify each stored chemical's hazard category (e.g., cal-hypo and trichlor are oxidizers under NFPA 400; muriatic/other acids are corrosives) using the manufacturer's SDS.
2. Segregate oxidizers from acids, fuels, and organic materials in physically separate storage areas or cabinets, following the SDS and product labeling.
3. Confirm with the local fire marshal/authority having jurisdiction (AHJ) what storage quantity thresholds trigger additional requirements (e.g., sprinklers, ventilation, segregation distances) under the locally adopted fire code referencing NFPA 400, since exact pound thresholds are set and enforced locally rather than by one fixed national number.
4. Check whether any stored chemical and quantity combination could trigger EPA Risk Management Program (RMP, 40 CFR Part 68) applicability — this depends on the specific listed substance and threshold quantity (e.g., gaseous chlorine is RMP-listed), not on pool chemicals broadly.
5. Maintain temperature control and keep storage areas within manufacturer-specified limits (e.g., cal-hypo degrades and becomes more hazardous if stored too hot).
