45、of which is water spray systems. Water spray systems appear similar to sprinkler systems in some respects; however, the intended uses, applicable Fire Codes and design criteria differ. This publication provides guidance for the petroleum industry and some petrochemical industry applications (for non

46、water-reactive petrochemicals with physical and combustion characteristics comparable to hydrocarbons) in determining where water spray systems might be used to provide protection from fire damage for equipment and structures. Damage to process equipment and structural steel also can be limited by

47、fireproofing, applying water through manual hose streams or applying water from fixed or mobile monitor nozzles; these methods are covered in API Recommended Practice 2218 Fireproofing Practices in Petroleum and Petrochemical Processing Plants, API Recommended Practice 2001 Fire Protection in Refine

48、ries and other referenced documents such as the National Fire Protection Association (NFPA) Fire Protection Handbook and various NFPA Codes.The specifics of water spray system design, installation and component types are covered in the publications referenced in Section 2, principally NFPA 15, and a

49、re not duplicated in this publication. The following other special applications of water spray are outside the scope of this publication: foam sprinkler systems used to supplement water spray systems and extinguish flammable liquid fires (see NFPA 16 for details); vapor mitigation systems which have been used successfully by several major corporations to reduce the potential effects of releases of hazardous materials such as HF acid (see API Recommended Practice 751 for additional information); water curtains used in special situations to minimize radiant heat or disperse hydrocarbo
