For SI: 1 foot = 304.8 mm, 1 pound = 0.454 kg.
- Where the amount of organic peroxide stored exceeds this amount, the minimum separation shall be 50 feet.
An approved supervised smoke detection system in accordance with Section 907 shall be provided in rooms or areas where Class I, II or III organic peroxides are stored. Activation of the smoke detection system shall sound a local alarm.
Exception: A smoke detection system shall not be required in detached storage buildings equipped throughout with an approved automatic fire-extinguishing system complying with Chapter 9.
Storage arrangements for organic peroxides shall be in accordance with Table 6204.1.7 and shall comply with all of the following:
- Containers and packages in storage areas shall be closed.
- Bulk storage shall not be in piles or bins.
- A minimum 2-foot (610 mm) clear space shall be maintained between storage and uninsulated metal walls.
- Fifty-five-gallon (208 L) drums shall not be stored more than one drum high.
