American Petroleum Institute Fireproofing Practice in Petroleum and Petrochemical Processing Plants
Design, location, spacing, and drainage are import in minimizing equipment involvement in a fire but additional protective measures may still be necessary. One protective measure is to improve the capacity of equipment and its support structure to maintain their structural integrity during a fire. Fireproofing achieves this with passive protection (PFP) in contrast to fixed water spray systems, monitors, or portable hose lines, which provide active protection. One example of passive fire protection is concrete.
