K-GUARD Wet Chemical INTRODUCTION 2014-DEC-29 REV. 03 PAGE 1 INTRODUCTION The K-GUARD 1.6 Gallon (6 L) wet chemical fire extinguisher (Model K01-1, K01-2, or K01-3) has been specifically designed to combat fires in restaurant kitchen cooking appliances. The fire extin guish ing agent is a specially-formulated aqueous solution. Newer, more efficient cooking appliances plus the use of non-saturated cooking oils require a fire extinguishing agent which will not only extinguish a fire but provide a cooling effect. This cooling effect is better realized with a wet chemical than with previously recommended dry chemicals. These attractive, easy to use and maintain stainless steel extinguishers have a hose and non-disruptive spray nozzle which allows the user to stand back at a safe distance while applying the agent to a cooking appliance. There is no blinding cloud of chemical so the user is able to apply the agent just where it is needed to extinguish the fire. Cleanup is quicker and easier since airborne particles do not spread to other areas.

K-GUARD Wet Chemical OPERATING INSTRUCTIONS 2014-DEC-29 REV. 03 PAGE 3 OPERATING INSTRUCTIONS! CAUTION Persons expected to use this extinguisher should be trained in initiating its operation and in proper fire fighting technique. Hands on training will prepare personnel with the feel for this extinguisher so that the most effective application can be utilized in an emergency situation. The basic operating instructions are contained in the pictogram on every nameplate (label). The following elaborates on these instructions.! CAUTION In case of appliance fire, use this extinguisher after fixed suppression system has been actuated.! CAUTION Use these extinguishers only on the proper type of fires as indicated by the symbols on the nameplate. Improper application could lead to personal injury or death. Example: wet chemical applied to an electrical (Class C) fire could cause electrocution. 1. Remove extinguisher from wall hanger bracket. 2. HOLD EXTINGUISHER UPRIGHT, twist and PULL RING (safety) PIN. REMOVE HOSE from clip. 3. START BACK a minimum of 8 FEET (2.4 m) from the fire. Grasp the hose and AIM the nozzle AT the BASE OF THE FIRE nearest you. 4. Keeping the extinguisher upright, SQUEEZE the LEVER to discharge. SWEEP the agent stream FROM SIDE TO SIDE AND CONTINUE TO APPLY UNTIL EXTINGUISHER IS EMPTY. (Continued application of the agent even after the fire appears to be out permits additional cooling and retards flash back.) 5. Evacuate and ventilate the area immediately after extinguishing the fire. The fumes and smoke from any fire may be hazardous and can be deadly.
INSPECTION AND MAINTENANCE PAGE 4 REV. 03 2014-DEC-29 K-GUARD Wet Chemical INSPECTION This extinguisher should be INSPECTED at regular intervals (monthly or more often if circumstances dictate) to insure that it is ready for use. (NFPA 10, 7.2.2) A quick check should be made of the extinguisher for the following: 1. Located in designated place. 2. No obstructions to access or visibility. 3. Operating instructions on nameplate (label) and facing outward. 4. Seals and tamper indicators not broken or missing. 5. Determine fullness by weighing or hefting. 6. Examine for obvious physical damage, corrosion, leakage or clogged nozzle. 7. Pressure gauge reading in the operable area. 8. Instruction placard is in its correct location and easily readable. MAINTENANCE MAINTENANCE (NFPA-10, 7.2.3) At least once a year (or more frequently if indicated by an inspection), MAINTENANCE should be performed. MAINTENANCE is a thorough check of the extinguisher. It is intended to give maximum assurance that an extinguisher will operate effectively and safely. It includes a thorough examination and any necessary repair or replacement. It will normally reveal the need for hydrostatic testing. 1. Clean extinguisher to remove dirt, grease or foreign material. Check to make sure that the instruction nameplate is securely fastened and legible. Inspect the cylinder for corrosion, abrasion, dents or weld damage. If any of these conditions are found and you doubt the integrity of the cylinder, hydrostatically test, using the proof pressure method and a suitable cage, in accordance with CGA Pamphlet C-1 and NFPA 10. Note: When cleaning, avoid use of solvents around the pressure gauge. They could seriously damage the plastic gauge face. 2. Inspect the extinguisher for damaged, missing or substitute parts. Only factory replacement parts are approved for use on Ansul fire extinguishers. 3. Weigh extinguisher and compare with weight printed on the Maintenance section of the nameplate (label). Recharge extinguisher if weight is not within the indicated allowable tolerances. 4. Check the date of manufacture on the extinguisher hanger loop. Cylinder must be hydrostatically tested every 5 years to the test pressure indicated on the nameplate 300 psi (20.7 bar). RECOMMENDATION: Replace extinguishing agent with new agent, as specified on nameplate, at time of hydrotest. 5. Visually inspect the pressure gauge: a. If bent, damaged or improper gauge, depressurize and replace. b. If pressure is low, check for leaks. c. If overpressurized (overcharged), invert the extinguisher and completely discharge contents. Recharge. 6. Check ring pin for freedom of movement by breaking the seal and removing the pin. Replace the ring pin if bent or if removal is difficult. 7. Inspect discharge lever for dirt or corrosion which might impair freedom of movement. Inspect carrying handle for proper installation. If lever, handle or rivets are damaged or distorted, replace with proper ANSUL part(s). 8. Remove hose/nozzle assembly. Inspect hose gasket (O-ring), hose, and nozzle assembly for damage; replace as necessary. Blow air through hose and nozzle to insure passage is clear of foreign material. 9. Inspect the valve assembly for corrosion or damage to hose thread connections. Replace valve assembly or component parts as necessary following the proper depressurization and recharge procedures. 10. Install hose assembly. 11. Install new visual seal and record service data on the extinguisher inspection tag. 12. Rehang the extinguisher on the wall hanger bracket making sure that it fits the hanger bracket properly replace the bracket if necessary.
