Emergency shutoff valves for laboratories must be positioned

Emergency shutoff valves for laboratories must be positioned

• A. Adjacent to the egress door and identified
• B. Near the main entrance
• C. In the basement
• D. At the furthest exit

Answer: (A)

The key idea is quick, safe access to the gas shutoff in an emergency. Placing the emergency shutoff valve adjacent to the egress door ensures anyone evacuating can reach it without stepping into the hazard area, allowing rapid isolation of the gas supply to stop leaks or fuel fires. Clear labeling or identification further speeds response because occupants and responders can recognize exactly where to operate the valve under stress or smoke. Valves located near other, less accessible spots—such as deeper inside the building, in basements, or only near the main entrance or far from the exit—risk delayed shutoff, which can worsen a leak or fire scenario. Keeping the valve near the exit and clearly identified aligns with the need for immediate, unblocked access during emergencies.
