What should not be attempted by FDNY members regarding outside steam valves?

FDNY members should not attempt to shut outside steam valves due to the potential dangers and complications that can arise from doing so. Outside steam valves are typically part of a larger, complex steam system, and improper handling could result in steam release, which poses serious risks, including burns or environmental hazards.

Handling steam valves requires specialized training and knowledge of the system’s operation, as well as an understanding of the potential impact on surrounding areas. Conditions may vary significantly across different systems, and there could be safety protocols or guidelines that specifically prohibit unauthorized personnel from engaging with these valves.

In contrast, monitoring valve pressure, assessing the valve for leaks, and opening the valve under specific circumstances can be within the scope of duties for trained personnel, provided they are following established safety protocols. This allows them to monitor the system's effectiveness and ensure that any issues are identified and reported to the appropriate maintenance teams.
