Dear Ms. Cannon:
This responds to your request for interpretation, dated December 4, 2000, concerning rejection criteria specified in the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) for hoses on cargo tanks used for the transportation of liquefied compressed gases. Specifically, you ask if a hose that has sustained minor damage to the outer hose covering must be removed from service. You provided samples of two hoses to illustrate your question.
Section 180.416(g)(1) of the HMR establishes rejection criteria for hoses on cargo tanks used to transport liquefied compressed gases. Paragraph (g)(1)(i) requires a hose with damage to the hose cover that exposes the reinforcement to be removed from service. In the sample of the damaged hose you provided, hose reinforcement is accomplished by means of a nylon-type material interwoven in the hose assembly and extending to the outer edge of the rubber outer hose covering. The damage to the sample hose exposed the nylon reinforcement. In this case, the hose would need to be repaired and tested prior to use.
The second sample hose you provided has several layers of protection between the rubber outer hose covering and the nylon reinforcement. This type of hose may continue to be used with minor damage to the outer hose covering, provided the nylon reinforcement layer is not exposed. A hose that has sustained damage sufficient to penetrate the outer layers and expose the nylon reinforcement must be repaired and tested prior to use.
I hope this information is helpful. If you have further questions, please do not hesitate to contact this office.
Sincerely,
Thomas G. Allan
