Ship design must take into account factors such as humidity, harmful gases, electrical equipment, etc. and take corresponding safety measures. For higher level explosion-proof places, it is necessary to use some special explosion-proof equipments, such as special explosion-proof fan heater, explosion-proof lamps, explosion-proof doors, explosion-proof electrical control box and so on.

Explosion-proof Grade：

For equipment with explosion-proof class II, explosion-proof equipment such as explosion-proof motors, explosion-proof junction boxes, and blowout preventers must be provided. In addition, explosion-proof lamps, explosion-proof tools are also necessary.

In the explosion-proof class I equipment, it must be equipped with electrical equipment, meters, cables, plugs, electrical connectors, etc. that meet the explosion-proof requirements. At the same time, also need to be equipped with explosion-proof isolation boards, explosion-proof switches, explosion-proof lights, explosion-proof electrical control boxes and other equipment.

Explosion-proof grade zero equipment requirements are relatively high, you need to configure equipment that strictly meets the explosion-proof standards, including gas detectors, explosion-proof distribution boxes, explosion-proof valves and so on. In addition, it is also necessary to cooperate with the fire prevention, explosion-proof building design and fire protection facilities.
