Knowing the locations of your facility’s gas, water main, water isolation valves and med gas valve shut-offs is more difficult than it sounds. Renovations, the number of years you’ve been on the job and the vastness of some campuses all contribute to the difficulty of finding these devices – coupled with the unavailability of location documentation. In facility emergencies, often times, the first thing that needs to be addressed are shut-offs. Knowing their locations and how to operate these devices is critically important.
