Dear Mr. Porter:
This responds to your February 27, 2001 letter requesting clarification on certain vessel stowage requirements for portable tanks of gasoline under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Essentially your inquiry relates to the required separation distance when stowing a portable tank of gasoline on deck relative to possible sources of ignition such as electrical equipment and fixtures that are not intrinsically safe or explosion-proof.
Although not explicit, the intent of the regulations with respect to stowage away from sources of ignition (see § 176.305(a)) is simply to apply the distance of 3 meters (10 feet) which is included in the definition for the term "away from" in the segregation provisions set forth in § 176.83( c )(2)(ii). Consequently, stowage of a portable tank of gasoline on deck on board a vessel should ensure at least a 3 meter (10 feet) separation from any sources of ignition.
I hope this answers your inquiry.
Sincerely,
John A. Gale
