Remote shutoffs in fixed facilities are typically located near the entrance.

• A. Near the exit
• B. Near the entrance
• C. In the basement
• D. Not marked

Answer: (B)

The main concept is that remote shutoffs in fixed hazmat facilities must be readily accessible to shut off the flow of hazardous material quickly, preferably from outside the hazard area. Placing the shutoff near the entrance achieves this: responders can reach it rapidly from the exterior or from the main access point without having to enter risky spaces, helping to stop the release sooner and reduce exposure.

Putting it in a basement can hinder fast access, especially if stairs are blocked or from smoke, fumes, or water. Not marking the shutoff makes it hard to find in an emergency, causing delays. Relying on a location near the exit isn’t as reliable for swift action from the outside, whereas the entrance location supports immediate intervention from the primary access route.
