Cargo room

Cargo rooms are provided on Navy or Marine vessels to store goods or bulk materials. The requirements on installed lighting equipment will differ depending on the type of goods being stored in the cargo room. If a vessel is storing dangerous goods such as munitions, fuel, oil or chemicals, lighting will need to be certified as explosion-proof in these areas. In most cases, one or more hatches will be set for dangerous cargo that require explosion-proof lighting.
Special demands for cargo rooms 
Cargo rooms are areas to store the different kinds of cargo. Often it is a dusty area sometimes exposed to rain with a high risk of mechanical damage to the installed light equipment. Chosen solution has to fit to the kind of vessel and cargo carried. Lights have to be sheltered mechanically by designing the cargo hold himself and to be very solid to withstand shocks and vibration during loading and unloading. As well as achieving a reliable light output, it is also important to provide the correct light intensity for storing and lashing. 

Important factors when working with lighting solutions for cargo rooms: 

- Explosion-proof lighting for hazardousareas. 
- IP class. 
- Mechanical strength/impact resistance. 

Explosion-protection 
When luminaires are installed in cargo holds, where explosible gases may occur , the light fittings must be certified according to the relevant explosion class and hazardous zone required for that area on the ship. 

IP class 
The IP rating of the light fittings is also critical for cargo rooms. The challenge here is not only protecting the light from rain during loading or unloading periods, but also the light fixtures must be designed to withstand intensive cleaning and washdowns using brushes, tools and sometimes high pressure cleaners. 

Mechanical strength/impact resistance 
Using the correct combination of materials in the luminaire is important, to ensure robustness and a long operating life. Materials are particularly important and should be selected to withstand high shocks and vibrations. Especially in cargo rooms, high shock levels may occur during loading and unloading of containers or bulk materials. Therefore, we always recommend the use of LED light fittings. LEDs withstand shock and vibration due to the design of the diodes. No additional vibration suspension is required. As vessels must be able to navigate to all regions of the world, from Arctic to tropical areas, it is important that installed lighting can operate across a wide range of ambient temperatures. In addition, ideally, the light output and light quality should be consistent across all temperatures. The lighting illumination should have an average level of 200 lux.

We always recommend the use of Navy or Marine approved lighting products in cargo rooms.
