If steam comes out of the bottom try cock, what should the boiler operator do?

When steam is escaping from the bottom try cock, it indicates a potential issue, such as a leaking drain or a possible malfunction on the boiler. It signals to the boiler operator that not only is there an immediate concern that needs addressing, but also that there may be a risk of further complications if the situation is not handled properly.

The correct course of action involves securing the fires and feedwater to prevent any further heat input and manage the pressure in the system. Allowing the boiler to cool down prevents additional steam from being generated and addresses safety concerns related to maintaining high-pressure steam in the boiler. Notifying the inspector is crucial, as they are responsible for ensuring the safety and proper operation of the boiler and can provide guidance on further steps to take, as well as necessary inspections or repairs.

This proactive approach prioritizes safety and regulatory compliance, making it the most prudent response to the situation. The other options, while they may seem relevant, do not adequately address the immediate concerns of managing the boiler's operation and safety.
