Dear Mr. Barber:

This is in response to your letter dated November 5, 1999, regarding segregation requirements under § 177.848(e)(3) of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180).  Specifically you ask if lab packs containing Division 4.1 and Class 8 liquids may be considered a truckload and therefore loaded above or adjacent to one another when offered by different shippers and transported by a single carrier.

The answer is no.  Section 177.848(e)(3) states that Class 8 liquids may not be loaded above or adjacent to Class 4 or Class 5 materials.  Section 177.848(e)(3) also states that shippers may load truckload shipments of such materials together when it is known that the mixture of contents would not cause a fire or a dangerous evolution of heat or gas.  The term truckload as used in this section means a shipment of hazardous materials loaded into a transport vehicle by a single shipper.  Shipments of hazardous materials offered to a carrier by different shippers and loaded into a transport vehicle are not considered to be a truckload.  Therefore, a carrier that receives Class 4 and Class 8 materials from different shippers must segregate the materials in accordance with § 177.848(c)(3).

I hope this satisfies your request.

Sincerely,

John A. Gale
