Phases maintenance

Fire extinguisher – initial verification and maintenance – UNI 9994 – 2

1. Surveillance: prevention measure adapted to control, with constant and particular attention, in the location where the fire extinguisher is placed, by carrying out a series of investigations. The monitoring can be carried out by personnel who are normally present in protected areas after receiving appropriate instructions.

2. Control: prevention measure in order to verify, at least once every six months, the efficiency of the extinguisher by carrying some investigations. The service control, review, and testing must be performed by trained personnel.

3. Revision: prevention measure, frequency at least equal to that indicated in the prospectus, in order to verify and make perfectly efficient fire extinguisher. prospectus specifies the frequency of revision, charging and \ or replacement of the extinguishing agent according to the following deadlines.

A dust 36 months
For water or foam 18 months
A carbon dioxide (CO2) 60 months

4. Testing: prevention measure in order to verify, with a specified frequency, the stability of the tank or cylinder extinguisher, as forming part of pressure vessels. Extinguishers and CO2 gas cylinders auxiliary must meet the deadlines specified by legislation and manufactured in conformity with Directive 97/23/EC (Legislative Decree 93/2000) must be tested every 10 years by a hydrostatic test duration of 30 seconds at a test pressure (Pt) indicated on the tank. Fire extinguishers that are not already subject to periodic accordance with the law and do not comply with Directive 97 \ 23 \ ce, must be tested every 6 years by a hydrostatic test of 1 minute at a pressure of 3.5 MPa , or as the value stamped on the tank if greater.
