Fire Suppression System Inspection Checklist

Use this Fire Suppression System Inspection Checklist to evaluate system functionality, ensuring all components are operational and ready for emergencies.

2. Is the FSS Inspection report available and dated within the last 6 months?

3. Are the inspection procedures for the FSS explained?

4. Are the training records for personnel conducting inspections available?

5. Who is the ANSUL representative responsible for maintenance? What is their contact information?

1. What is the manufacturer of the FSS?

2. What is the model of the system?

3. Is the system classified as manual or automatic?

4. What are the sizes and number of tanks in the system?

5. Is there a maintenance tag on the actuator or tank that is dated within the last 6 months?

1. Are the ring pin and tamper indicators present on both actuators (one accessible from the ground and one in the operator's compartment)?

2. Is the red actuator button easily accessible for a full arc hit with the hand and undamaged?

3. Is the actuator bottle securely fastened and not loose?

4. Have mine personnel with FSS maintenance training safely removed the actuator bottles?

5. Are the actuator bottles inspected for punctured seals, rust, or other damage?

6. Is the ring pin in place before mine personnel reinstall the actuator?

1. Is the actuator hose a 1/4” hose with SAE 100R1 or 100R5 markings : If markings are not legible, has documentation been requested from the mine operator?

2. Is the actuator hose a 1/4” hose with SAE 100R1 or 100R5 markings : Is the hose stiff and wire-reinforced rather than just rubber?

3. Is the routing of the hose positioned away from heat sources, electrical wires, and moving parts?

4. Is the hose routed away from the engine compartment: If it is in the engine compartment, has documentation on the routing been requested from the mine operator?

5. Is the hose routed away from the engine compartment:In areas where the temperature exceeds 200°F, is the hose sleeved with a heat-resistant fire jacket at each metal fitting?

6. Is the hose clamped at least every 5 ft., with no loose connections?

7. Is the hose inspected for holes, abrasion, or other damage, especially where it passes through bulkheads?

8. Are check valves present in each actuator line, and do the arrows point toward the expellant tank?

9. Is the expellant bottle hand-tight and securely fastened? Is the top fitting tight?

10. Is the hose from the expellant bottle to the chemical agent tank a 1/4” hose with SAE 100R1 or 100R5 markings : If markings are not legible, has documentation been requested from the mine operator?

11. Is the hose from the expellant bottle to the chemical agent tank a 1/4” hose with SAE 100R1 or 100R5 markings :Is the hose stiff and wire-reinforced rather than just rubber?

12. Is the routing of the hose positioned away from heat sources, electrical wires, and moving parts?

13. Is the hose clamped at least every 5 ft., with no loose connections?

14. Is the hose inspected for holes, abrasion, or other damage, especially where it passes through bulkheads?

1. Is the chemical agent tank free from rust, dents, and other damage?

2. Is the tank opened only if there are signs that the system has been activated (e.g., powder on the machine or in the nozzles)?

3. If there are signs of activation, can trained mine personnel open the tank?

4. Is the agent tank filled to the proper level with dry chemicals?

5. Can the proper levels be confirmed against the size tank specifications?

6. For larger tanks, is the red indicating the stem is raised and visible, indicating the tank has been pressurized?

7. Is the pressure gauge on larger tanks indicating in the green range?

1. Are the distribution hoses of various sizes marked with SAE 100R1 or 100R5: If markings are not legible, has documentation been requested from the mine operator?

2. Are the distribution hoses of various sizes marked with SAE 100R1 or 100R5:Are the hoses stiff and wire-reinforced rather than just rubber?

3. Is the routing of the distribution hoses away from electrical wires and moving parts?

4. Are the hoses routed away from heat sources, such as the exhaust manifold, pipe, or turbocharger?

5. Are the hoses clamped at least every 5 ft., with no loose connections?

6. Are the hoses inspected for holes, abrasion, or other damage, especially where they pass through bulkheads?

1. Are the hydraulic hoses properly clamped?

2. Are the hoses not rubbing on the machine frame?

3. Are the hoses not contacting electrical wires?

4. Are there no hydraulic oil, engine oil, or fuel leaks?

5. Is there no exposed wire braid?

1. Are the nozzles unblocked, with no non-OEM installed components?

2. Do all nozzles have caps (orange for dry chemical nozzles, blue for LVS nozzles)?

3. If chemical residue is found in a nozzle:Have mine personnel been asked when the system was last activated and documented that it was recharged?

4. If chemical residue is found in a nozzle:Is there documentation of who performed the maintenance?

5. If chemical residue is found in a nozzle:If documentation is not available, should mine personnel open the chemical agent tank to check the chemical level?

6. Do the nozzles adequately cover critical areas, including: The top center of the engine and turbochargers

7. Do the nozzles adequately cover critical areas, including: The right and left sides of the engine

8. Do the nozzles adequately cover critical areas, including:The rear of the engine, hydraulic pumps, and transmission

9. Do the nozzles adequately cover critical areas, including:The battery compartment, parking brake, belly pan, and hydraulic and fuel tanks?
