In your letter, you describe a scenario in which you have a skid of Class 1.4 explosives, packaged, placarded, and strapped to the flatbed of a pick-up truck. You ask whether the truck may be loaded the night before delivery provided the truck and warehouse is locked. You state that the warehouse has an alarm system with code- specific security gates at the entrances. The term "in transit" is not defined in the HMR. However, for purpose of the HMR, as defined in § 171.8, ''transportation" or transport means the movement of property and loading, unloading, or storage incidental to that movement. With respect to the pick-up truck, it may be loaded the night before delivery. Explosives stored temporarily at a location en route to its destination is considered "storage incidental to transportation" or "temporary storage." Although no specific length of time is prescribed in the HMR, as specified in § 177.800( d), all shipments of hazardous materials, including explosives, being transported by motor vehicle (in this case, a pick-up truck) must be transported without unnecessary or undue delay, from and including the time of the start of loading of the hazardous materials until its final unloading at the destination. (Also, for your information, see§ 172.800 for security plans and applicability.) I hope this information. Please contact this office should you have additional questions. Sincerely, T.
