each of the crash trucks assigned to the fire-fighting crew. The kit consists of a canvas tool roll with pockets or holders for specified tools. The crash kit contains tools for forced entry. Fire fighters use these tools in rescuing occupants trapped in aircraft. The kit contains three tapered, hard-rubber plugs and three hardwood plugs. These plugs are used to stop fuel tank leaks. PROTECTIVE CLOTHING Aircraft fire-fighting/rescue protective clothing is a prime safety consideration for personnel engaged in fire-fighting and rescue work. Aluminized protective clothing offers a means of providing protection to fire fighters because of its high percentage of reflectivity to radiant heat. Aluminized proximity fabrics have been adopted for use in the Navy Mishap/Rescue Program. It is important to point out that these garments are not classified as entry suits, but are known as proximity clothing to be worn with fire fighter's knee-length boots that have safety toes and soles. Care and Maintenance of Protective Clothing The heat-reflective ability of aluminized clothing is reduced when the clothing is stained or otherwise soiled. Therefore, you  must  give careful attention the care and maintenance instructions for protective clothing. Some guidelines are as follows: 1. Store  clothing  on  hangers,  with  suitable hanging space to prevent aluminized fabrics from creasing or cracking. If the garment is folded, the folds should be loose. Do not sit on a folded garment. 2. Sponge off dirt and soot by using mild soap and water. Dry aluminum surfaces with a clean cloth. Rub gently to avoid removal of the aluminum. 3. Remove grease stains by using dry-cleaning solvents. (NOTE: Isopropanol or perchloroethylene will react with the metal in proximity suits and may etch the aluminum surface.) Clean the clothing with water and wipe dry. Allow the garment to hang in a ventilated location at room temperature. 4. Remove AFFF by sponging the clothing clean with mild soap and water. Hang the garment to dry in the open or in a place with good circulation. During fire-fighting operations, it is not always possible to prevent fire-fighting agents from getting on protective clothing. However, aluminized protective clothing that has been covered or spotted with agents will have less heat-reflecting ability than the suit normally would provide. 5. Corrosive  chemicals  will  react  with  the aluminum surface and may etch the metal. Clean the clothing with water and wipe it dry. Allow it to hang in a ventilated location at room temperature. 6. Replace garments when the aluminum wears off or when the fabric cracks or tears. Spraying worn clothing with aluminum serves no useful purpose and is a dangerous practice. Care of Facepiece The gold-coated facepiece is a heat-reflective shield. The facepiece is NOT a sun shield. This item should be kept in excellent condition to maintain the radiant-heat-reflective efficiency. When the gold surface of the facepiece becomes worn, scratched, or marred, 90 percent of the heat protection is lost, and you should immediately replace the facepiece. Other precautions you should take with facepieces are as follows: 1. Keep the protective cover in place when you are carrying or storing the hood to minimize damage to the gold-coated surface. Remove it when using the hood. 2. For  adequate  protection,  replace  a  worn gold-coated facepiece. When wearing the facepiece, make sure the gold surface is on the outside as marked on the edge. 3. Avoid touching or wiping the gold surface as much as possible. 4. Clean the facepiece, without removing it from the hood, by using a clean, soft cloth with mild soapy water, and then rinse and pat dry. Q12-6. What size diameter are the fireplug outlets aboard ship?
