OUR JOB- Find the bad one’s…
The US Department of Transportation (DOT) requires all extinguisher and air cylinders to be hydrostatically tested every 3, 5, or 12 years. The frequency varies based on the type of material, the gas it contains, the age, and special permits the cylinder was manufactured under. Security Fire Equipment has been a registered extinguisher and cylinder hydrostatic retesting facility for over 25 years. Our retest technicians are current and up to date on State and Federal hydro test requirements.
- Fire Extinguishers
- Carbon Dioxide Cylinders (Beverage- Kegerator)
- SCBA Cylinders
Cylinders are tested using the water jacket (hydro) method. This consists of enclosing the cylinder (filled with water), suspending it in a jacket vessel, and pressurizing the cylinder to a specific test pressure. With this process, our safety professions are able to measure pressure losses, or leaks, as well if there are any deformations or weaknesses. Once a cylinder passes the inspection, it is stamped and labeled with the month and year, so you can keep track of testing times. If a cylinder fails an inspection, be it rare, it is required to be disposed of and retired from service.
