Dear Mr. Maham:
This responds to your July 25, 2011 letter requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to the on deck segregation of freight containers carrying incompatible explosives in accordance with § 176.144(a). In particular, you ask if these freight containers must be segregated 20 ft (6m) fore and aft and 8 feet (2.5m) athwartship from each other in accordance with § 176.170(f) or 20 feet (6m) from each other in all directions in accordance with § 176.144(e).
Freight containers carrying incompatible explosives must be segregated in accordance with § 176.170(f) and 176.83(f) or 176.83(l)(3), as appropriate. Section 176.144(e) does not apply to the segregation of incompatible explosives in separate freight containers. Although not specifically stated, § 176.144(e) only applies to the segregation of individual packages, pallets, or magazines containing incompatible explosives when on deck.
I hope this satisfies your inquiry. Please contact us if we can be of further assistance.
