NFPA 850 is the National Fire Protection Association’s (NFPA) recommended practice for protection of electric generating plants and high-voltage direct current converter stations. Chapter 10 identifies hazards and protections for wind-power facilities.
Without set laws, wind-farm owners must independently develop their own fire-emergency plans. Most wind turbines do not routinely have fire-detection and control systems installed by OEMs because this option is simply not ordered or required by the end user.
Some concerns with installing fire-detection and suppression systems in wind turbines include cost, false alarms, guaranteed fire prevention, electrical equipment damage, and worker and environmental safety.
Traditional detection devices are also worth investing in, such as linear heat-wire, smoke and heat detectors, and air-purification systems.
