Power generation facilities… whether hydroelectric, nuclear, or fossil fuel… all present significant and varied fire hazards, from both the fuel and the rotating machinery. Fire also poses a significant business risk, not only because power plants are a major capital investment, but also because downtime can have serious repercussions for those who depend on an uninterrupted supply of electricity.
CONSIDERATIONS & PROTECTION
The combination of a fuel source and high heat create conditions where a malfunction could quickly lead to a destructive fire. Turbines are protected with CO2 or water mist. Fires resulting from ruptured fuel lines feeding diesel engines can be extinguished with a water mist system that blankets the area with a fog.
Computer and control system equipment near high voltage poses a risk of electrical fire. Smoke and heat detection in combination with waterless clean agent suppression will extinguish fire without causing harm to control room equipment.
This natural environment for hazards due to fire or toxic fumes can be protected with early warning smoke and gas detection using air sampling systems.
Outdoor transformers should be protected with heat detection and deluge sprinkler systems.
High voltage cable running through a confined space is monitored with smoke and heat detection. Linear heat detection provides a fast indication that conditions are changing and require immediate attention.
