Whether they are at a working structure fire, a miscellaneous still alarm, or a gas or electricity call, it is essential that fire crews have the ability to control an occupancy’s utilities. All occupancies have electric service, providing needed power for lighting and electronics and many have natural or propane gas providing heat and cooking fuel.
The first step you should take is to locate the utility service. At residential structures, you can normally find these on the side of the home opposite the parking area or garage. However, this location can vary. The first-due officer should note this during his 360° size-up. The utility service location can also vary on commercial properties, but you can find it easily during building walk-throughs and if they are marked properly on preincident plans. This saves time and headaches during a true emergency.
当今的许多电力从地下饲料中流入仪表，较旧的结构可能会有滴水环将电力从主杆上降低到仪表。无论哪种方式，仪表都可以从实用程序中提供功率，并且可以测量进入结构的功率。可以从结构的外部拉出仪表并削减功率，但这不是整个行业的常见做法。
A safer means to secure the power is to locate the breaker box; this panel takes in the power from the outside meter and then distributes it through a series of breakers to the rest of the structure, where power is needed through a system of electric lines.

Securing power at this location is simple and safe: Turn off the breakers starting at the bottom and work your way to the top, finishing with the main breaker controlling the utility. Repeat this procedure for multiple panels as you would in a commercial structure or a large home with multiple panels. This procedure also allows you to isolate an area that is an area on fire such as a small kitchen, allowing you to extinguish it with minimal damage. If the home is still inhabitable, you can isolate the kitchen through the panel and allow electricity to flow through the remainder of the home.
气体 - 天然或丙烷。确保流量的最简单方法是关闭电表之前关闭内联阀。您可以将这个四分之一的（通常是在线）阀（90°）转动，将其关闭到结构的气体。您可以使用扳手扳手的盒子部分，一对频道锁或Halligan的叉子旋转。永远不要试图强制这个阀门；它可能会破坏或损坏阀门。
每当与公用事业打交道时，请始终跟进本地公用事业公司。让他们响应，验证和恢复服务；他们是真正的专家。花一些时间来审查公用事业紧急情况，并查看当地建筑物中的公用事业服务连接。弄清楚这一切的最佳时间是在紧急情况发生之前。
