The Boat Safety Scheme (BSS) is an organization founded jointly by British Waterways and the United Kingdom Environment Agency to promote boating safety and protection of the marine environment. Examiners certified by the organization to conduct safety checks of boats have found that dome-shaped bullseye decklights have the potential to cause fires.
Bullseye Decklights Have the Potential to Cause Fires Aboard
The shape of bullseye decklights focuses and intensifies the light that enters a boat. Objects that lie within the focal point of the decklight can be heated and scorched by the intense light. Every year BSS examiners find evidence of heat damage from bullseye decklights and there are frequent reports of vessel fires attributed to this source.
In a press release concerning the fire hazard, BSS Program Manage Graham Watts says, “If you have a bullseye decklight fitted, please check any surfaces below it for signs of scorching. Even if there is no sign of damage make sure that anything that can be affected including any loose objects, are kept at least 300 mm away from bullseyes.”
What are Bullseye Decklights?
Boats have been fitted with bullseye decklights for more than a hundred years. These devices are designed to let natural light filter into the spaces found below deck. Light striking the dome of the bullseye is dispersed sideways into the space below. Using a flat piece of glass as a decklight isn’t as useful, since light passing through travels straight down.
Historically the use of decklights was particularly useful in illuminating spaces where hazardous cargoes like coal or gunpowder were stowed and the use of flame-generated light wasn’t safe. An added bonus was that crews could monitor cargo for fire by seeing firelight through the decklights.
Safety Hints for Boat Owners With Bullseye Decklights
During 2010, the BSS has already noted three incidents involving bullseyes. The worse of the lot was a fire that started in area containing towels and a toiletry aerosol, which spread into the cabin of the boat. Boaters are advised to inspect the areas surrounding a decklight for overheating, scorching, or charring. Flammable items should be stored outside of the bullseye’s focal point.
Boaters in the United Kingdom can request a BSS examination that is aimed at reducing the risk of shipboard fire and pollution. Examiners look at onboard fuel, gas and electrical systems, appliances and required safety equipment. Certificates are valid for four years and required by many navigation authorities for licensing, registration or toll renewals. Details concerning the examination can be found in the BSS Essential Guide that may be viewed at the Boat Safety Scheme website.
