In a basic emergency shutdown procedure, critical steps involve isolating potential hazards. Shutting off power to machines and fans prevents electrical hazards and stops machinery that could worsen the situation (e.g., spreading fire). Closing valves is essential to contain potential leaks of hazardous substances or to control flow in critical systems.
– Shutting off power (1) and closing valves (3) are standard safety procedures in many emergency shutdowns to prevent escalation of the incident or injury.
– Opening windows (2) might be done in specific emergencies (like gas leaks) but is not a universal step in a *basic* shutdown, especially if security or containment is an issue (as noted in the option itself regarding bomb threats).
– Unplugging vents and pipes (4) is generally not part of a basic shutdown procedure and could potentially create new hazards or interfere with containment systems. Shutdown procedures focus on isolation and securing systems, not disconnecting them in a manner that might release contents or disrupt safety features.
Emergency shutdown procedures are designed to quickly bring equipment and processes to a safe state in response to an emergency such as fire, explosion, hazardous material release, or security threat. The specific steps vary depending on the type of facility and the nature of the emergency, but fundamental actions include cutting power and isolating substances/systems.
