In a clean surgery department, oxygen supply facilities serving patients need to be provided to meet surgical needs. For larger-scale surgery departments, oxygen is generally delivered from centrally stored oxygen tanks to the operating rooms through pipelines. Oxygen is a combustion-supporting agent and is classified as a Class B fire hazard article. In a fire, oxygen will intensify the fire. The fundamental method of extinguishing a gas fire is to cut off its gas supply source.

The surgery department comprises various functional rooms. Although there is a certain degree of fire separation between them, the oxygen pipelines in all the relevant rooms are all connected with Figure 10.6 Examples of Fire Safety Sign Installation

Connection of the central oxygen supply main pipe. In the event of a fire in the surgical department, only by promptly shutting off this central oxygen supply main pipe can more serious hazards be effectively prevented. In addition, the design of such a measure should also take into account the needs of certain areas within the surgical department where the oxygen supply must not be interrupted; that is, in actual operation, the shutoff should be carried out only after ensuring that these areas already have other means of oxygen supply. Therefore, the measures specified in this provision should generally be installed in locations within the surgical department that are convenient to control and relatively safe, and should be capable of completing the shutoff procedure by remote control.
