| Annual Maintenance & Certification |
| On an annual basis each Fire Extinguisher shall be inspected to include the following. |
| |
 |
Visual Examination for any signs of dents, rust, corrosion or other shell damage. |
 |
|
Check Pressure gauge to insure unit is fully charged. |
|
Remove discharge hose and inspect for signs of blockage. |

Make sure Fire Extinguisher is accessible. |
|
Check hazard application to ensure proper type of Fire Extinguisher matches any potential fire. |
|
Clean extinguisher if needed. |
|
Locate latest test date to determine if the Fire Extinguisher requires a cylinder hydro-test or 6 year internal inspection. |
|
Attach new service tag and return to proper location. |
|
| |
| 6 Year Internal Inspection |
| Six years after manufacture date all Dry Chemical, Halon and Halotron Fire Extinguishers are required to be discharged, disassembled, rebuilt and recharged before being certified and put back into service. This service would include the following. |
| |
|
Discharge of all chemicals. |
 |
|
Remove the Fire Extinguisher head for rebuilding. |
|
Clean all internal and external parts. |
|
Replace "O" ring. |
|
Examine valve stem and replace if needed. |
|
Examine inside of cylinder for any pitting of cylinder wall and proper discharge of extinguishing agent. |
|
Fill cylinder with proper chemical and place verification collar on neck of cylinder. |
|
Reassemble and pressurize the Fire Extinguisher to the proper pressure level.. |
|
Attach new service tag and return to service.. |
|
| |
| Cylinder Hydrostatic Test |
| Fire Extinguisher cylinders must be pressure tested periodically to check for structural weaknesses. Dry Chemical, Halon and Halotron extinguishers are tested at intervals of 12 years. Carbon Dioxide, Water and Class K extinguishers are tested at intervals of 5 years. At this time, the steps taken for 6 year internal inspections would also be performed. |
| |
| Fire Extinguisher Recharge |
| Whenever a Fire Extinguisher is discharged a recharge is required before placing that extinguisher back in service. This process is exactly the same process used for a 6 year internal inspection. |
