Protect the Parts Cleaning Dip Tank The dry chemical system is good for class B fires. The hazard falls into class B because the chemicals in the clean dip are inflammable. The agents are, usually, sodium bicarbonates transported through gases to aid the fluidization process (Bryan n.pag.). The particles extinguish fires by coating them and cutting off oxygen supply. Type 80-B extinguishers should be installed 50 feet apart. The local application system serves well because the extinguishing exercise only concentrates on the exposed part of the tank. Design NFPA 17 recommends IND-25 and IND-50 cylinders. UL 300 requires a manual fuel shut-off pull for all power sources (Bryan n.pag.). On the other hand, UL 1254 requires systems to discharge the dry chemicals on the protected area (“Fire extinguisher placement” par. 3). Containers that store these chemicals should be non-reactive metals that can store 200lbs of the agent. The nozzles, piping and fittings should also be non-combustible and compatible with the agents (Bryan n.pag.). They should withstand the gas pressure. Stainless steel and copper work very well. The visual inspection should check the installation method, the type of nozzles, pipes, and agents. On the other hand, discharge tests should include verifying the operation of the nozzles, capturing and weighing the products and using balloons to capture the agents (Bryan n.pag.). The acceptance test should involve confirming the operation of the device and activating the alarm and the manual and automatic release. Maintenance should follow the manufacturer’s guidelines. The company should schedule maintenance and tests after one month, six months and one year. Advantages   * Effective at putting out class B fires   * No water-related damage to the equipment Disadvantage   * The chemicals react with some metal containers. Paint Spray Booth The total flooding delivery system is the best method for applying halons in the booth because it is an enclosure. Several nozzles should be used to fill the booth with the halon. The best halon agent is 1301. Design, Type and installation According to UL 1254, the system should have 3 IND-50 cylinders, 1 IND-25 cylinder and eight nozzles on the face of the booth. It should also have two total flood nozzles on the work area, two duct nozzles on the plenum area and two duct nozzles on the duct area. The liquids in the booth are inflammable. Hence, class B extinguishers should be installed 50 feet away from each other (Bryan n.pag.). According to NFPA, there should be weekly and monthly inspections to eliminate conditions that hinder operations. Inspections should also help establish changes in the hazard and monitor damages or leakages on the equipment. The company should also check the liquid and pressure levels and conduct ten-minute pneumatic pressure tests to establish leakages. Furthermore, they should conduct puff tests and enclosure integrity tests to ensure the continuity of the pipe and prevent leakages (Bryan n.pag.). The tests ensure that concentration levels remain at 80 %. Advantages   * They effectively break down the reactive chains of the fire   * They are not reactive with materials in the surrounding Disadvantages   * They do not work well on reactive metals, areas with oxygen and metal hydrides.   * They have a negative effect on the environment.
