Harbour Masters Notice 1-94: Local Requirements For Hazardous Materials


This notice supersedes the Harbour Master Notice 4-89 dated 17 August 1989 on this same subject. It is intended that this notice will provide updated guidance that takes into account current shipping practices as well as state and federal regulations.

Honolulu Harbour is a relatively small port, yet it provides Hawaii's economic lifeline to the outside world. As a result, the state can ill afford any kind of incident involving hazardous materials which could result in the closure of part or all of the port.

The limitations/requirements listed below have been developed and updated throughout the years with the foregoing in mind. Naturally, all federal regulations must be complied with - to the satisfaction of the U.S. Coast Guard and the Harbour Master. Hazard classes for explosives have been revised to reflect coding changes required under Code of Federal Regulations 49-1991.

Shippers and importers of hazardous materials are also reminded of Act 185, Session Laws Hawaii 1989, a new law that, among other things, requires notification of Fire and Police Departments at least 48 hours prior to transporting explosives by motor vehicles.

The requirements contained below are applicable to all shipments, including inter-and-intra island cargo.
