Special Division 1 is a Class I, Zone 0 hazardous location in Article 505 of NFPA 70 (incorporated by reference, see § 110.10-1) that may require special considerations for electrical equipment installed in such locations.
Waterproof means watertight; except that, moisture within or leakage into the enclosure is allowed if it does not interfere with the operation of the equipment enclosed. In the case of a generator or motor enclosure, waterproof means watertight; except that, leakage around the shaft may occur if the leakage is prevented from entering the oil reservoir and the enclosure provides for automatic drainage.
Watertight means enclosed so that equipment meets at least a NEMA 250 Type 4 or 4X or an IEC 60529:2013 IP 56 rating.
Zone 0 is a hazardous location in which an explosive gas or vapor in mixture with air is continuously present or present for long periods.
Zone 1 is a hazardous location in which an explosive gas or vapor in mixture with air is likely to occur in normal operating conditions.
Zone 2 is a hazardous location in which an explosive gas or vapor in mixture with air is not likely to occur in normal operating conditions, or in which such a mixture, if it does occur, will only exist for a short time.
§ 110.20-1   Equivalents.
The Commanding Officer, Marine Safety Center (MSC), may approve any arrangement, fitting, appliance, apparatus, equipment, calculation, information, or test that provides a level of safety equivalent to that established by specific provisions of this subchapter. Requests for approval must be submitted to the Marine Safety Center. If necessary, the Marine Safety Center may require engineering evaluations and tests to demonstrate the equivalence of the substitute.
