1. In corrosive environments it is desirable to have the discharge test carried out at half the frequency mentioned.

2. As for the restriction on release of Halon in atmosphere, it need not be necessary to refill/operate Halon 1211 type portable fire extinguisher within any stipulated period. However as regards the pressure of injections gas i.e., dry N₂ it should be checked up for the adequate pressure on the press are gauge/indicating gauge and the contents by weighing the fire extinguisher.

E-1 Every extinguisher installed in premises shall be hydraulically pressure tested as per the schedule given below. There shall not be any leakage or visible distortion. Extinguisher which fails in this requirements shall be replaced.

E-2 The carbon dioxide type and Halon 1211 type fire extinguishers shall be pressure tested every time the cylinders are sent for recharging ( after periodic discharge test or otherwise ) to the pressure specified in the relevant Indian Standard specifications.
