Fire hydrants are most commonly used water-based suppression systems for general fire fighting requirements. Automatic water sprinklers are used where quicker responses are required. Automatic gas-based systems are used to protect expensive industrial equipment. CO2 and FM200 are commonly used fire extinguishing gases. Larger applications also employ foam based suppression techniques. Rakshak promotes the appropriate usage of these systems for greater risk coverage and minimum damages due to a hazard.
