Fire Demands Special Fire Lights
The tail lights in fire lights, their attaching mechanisms
, and their smoke proof, water proof, and shock proof designs aid the firemen perfectly in their job. The heat and light created by a necessary fire will be beautiful and helpful, while that created by an accidental fire will be ugly and ruinous. In the burning aftermath of an unnecessary fire, visibility is decreased and rescue operations are hindered by darkness, smoke and heat. To combat that heat and smoke, firefighters need special types of fire lights without which their job might remain hopelessly under performed.
All types of fire lights are designed to be shock proof, smoke proof, dust proof, and waterproof. These lights have to be shock proof, because, in the type of decreased visibility atmosphere that firefighters have to operate, the possibility of hitting against hard objects is very high. Impact resistant and chemically resistant nylon polymer, which is rugged and lightweight, is used for the body of many models of fire lights. These will easily withstand even a drop of 30 feet.
Fire lights need to be water proof also because water is the single largest thing that will pour down at the venue of an accidental fire. Different models may be waterproof to different extents and different depths, but most will be waterproof for at least 30 minutes. O-ring seals are used in many fire lights to make them water resistant.
Many fire lights will have a forward facing light as well as one or more taillights. The tail light is very important in fire lights because even as the firefighter moves forward in his rescue operations, it is important that the other firefighters in the group are able to follow him without losing track. These safety taillights will be blue in most cases since blue ensures better visibility in a smoke filled room.
All fire lights will have provision to be strapped to the user's body or to any part of the duty gear so that his hands remain free for other jobs. Some lights are designed to be attached to fire helmets that have a brim, and will be provided with swivel clamps with which they can be attached above or below the helmet. When swivel clamps are used for attaching, the lights can be rotated full 360o on it, to train the light in the required direction. Whichever way the fire lights are attached, the attaching mechanism will lend itself to easy release that will enable the user to handhold it, or reattach it in some other position.
Fire lights rely on halogen, strobe, or LED technology for its light, just like other types of emergency lights. LED is becoming more and more popular for use in fire lights mainly because of the long bulb life that LED can provide. The bulb in LED lights, which can produce ultra bright light, will never have to be replaced in the user's lifetime because many of these will have a bulb life of up to 50,000 hours. Only the batteries will need to be recharged in these fire lights.
