This RP identifies fireproofing needs for petroleum and petrochemical plants specifically focusing on property loss protection for pool fires scenarios in on-shore processing plants. Only passive fireproofing systems are within the scope of this recommended practice. The following are outside the scope of this RP, however this RP contains information which may be useful in these applications: - fireproofing for LPG storage vessels (see API 2510 and API 2510A), - fireproofing for personnel protection, - fireproofing for buildings. Purpose This recommended practice (RP) is intended to provide guidance for selecting, applying, and maintaining fireproofing systems designed to limit the extent of fire-related property loss from pool fires in the petroleum and petrochemical industries. Where comparable hazards exist, and to the extent appropriate, it may be applied to other facilities that could experience similar severe fire exposure and potential losses
