TRANSPORTATION OF CHLOROSILANES IN MC 331 CARGO TANKS

摘要

Ms. Pink sought the LOI regarding the applicability of §178.337-9(a)(1) would apply to the transportation of chlorosilanes. Based upon Momentive's review of the regulation 49 CFR Part 178.337-9(3), for a MC 331 Cargo Tank in the above service, the pressure relief valve for this tank "must be designed, constructed, and marked for a rated pressure not less than the cargo tank design pressure at the temperature expected to be encountered". It is unclear however as to whether 49 CFR Part 178.337-9(a) would apply for a MC331 in this service. This regulation references 49 CFR Part 178.315(ⅰ).
