In order to comply with the Texas State Fire Marshal, businesses are required to have their fire extinguishers up to date in three areas. The three areas are annual maintenance, six year maintenance, and hydrostatic testing.
Every year a fire extinguisher must be inspected and certified. During an annual maintenance, a fire extinguisher will be given a 12 point inspection. This means that our technicians will look for any swelling or comprisable damage to the extinguisher, and then ensure that the extinguisher is holding in the required pressure by checking the gauge.
After the visual check, our technicians will give the extinguishers a physical check. This process allows our technicians to ensure the extinguisher has the proper weight and that the hose is sealed correctly to the extinguisher. Once the extinguisher has passed both inspections, our technicians will properly tag the extinguisher as a visual sign that the extinguisher is ready in case of a fire.
Six Year Maintenance
Every six years the Fire Marshall requires a fire extinguisher to undergo a six-year inspection. This type of inspection requires all pressure to be removed from the fire extinguisher, and then thoroughly cleaned. When our technicians perform a six-year maintenance on a fire extinguisher, they first must safely release all the pressure. Once all the pressure has been released, the “head” of the extinguisher is pulled out of the extinguisher. The head of the extinguisher is what allows for the powder to be released in the case of a fire, so it is imperative that this piece is in tip-top shape.
Our technicians will completely disassemble the head of the extinguisher and clean every part from powder that has collected. By ensuring that every part if clean, the “head” is able to have a tight seal which allows for optimal use when needed. After a thorough cleaning, our technicians will reassemble the “head” of the extinguisher and reinsert the head into the cylinder. From here, our technicians will pressurize the extinguisher and then give an annual inspection. Once the extinguisher has passed all of the inspections, the extinguisher will be tagged.
In order for a fire extinguisher to be effective, it has to be able to be ready at any point. All fire extinguishers are made to last up to thirty-years requiring a hydrostatic test to be performed every twelve-years starting from the manufacturers date on the cylinder. To comply with Texas State Law, Fire Shield has specific equipment designed to perform the test as well as the experience as trained professionals.
During a hydrostatic test the process is similar to a six-year maintenance, however, the cylinder is pressure tested to ensure it is in optimal condition. In this process, our technicians will remove the head of the fire extinguisher and clean it thoroughly. Then the cylinder will be filled with water and then pressurized to 300psi. The pressure test will show if the fire extinguisher can last another twelve years. If the extinguisher passes the pressure test, it will be dried out and then reassembled. Our technicians will then tag the extinguisher and place a testing sticker on the cylinder.
