API Publ 2218

Fireproofing Practices in Petroleum & Petrochemical Processing Plants
Edition: 2nd
American Petroleum Institute / 01-Aug-1999 / 46 pages
This publication is intended to provide guidance for selecting,applying, and maintaining fireproofing systems that are designed to limit the extent of fire related property loss in the
petroleum and petrochemical industries.1.2 RETROACTIVITY
The provisions of this publication are intended for use in designing new plants or considering major expansions. It is not intended that the recommendations in this publication be applied retroactively to existing plants. This publication can be used as guidance if there is a need or desire to review existing capability or provide additional fire protection.
This publication uses a risk-based approach to evaluate fireproofing needs for petroleum and petrochemical plants in which hydrocarbon fires could rapidly expose structural supports to very high temperatures. Fireproofing can protect against intense and prolonged heat exposure that could cause collapse of unprotected equipment and lead to the spread of burning liquids and substantial loss of property. This guideline specifically addresses property loss protection for pool fires scenarios but not jet fires or vapor cloud explosions.
Fireproofing may also mitigate concerns for life safety and environmental impact. Additional fire-resistance measures may be appropriate for fire protection where hazardous chemicals could be released with the potential for exposure of persons on site or outside the plant. Regulatory compliance is not addressed by this publication.
Although widely used, the term “fireproofing” is misleading as almost nothing can be made totally safe from the effects of fire. Fireproofing refers to the systematic process
(including materials and the application of materials) that provides a degree of fire resistance for protected substrates.This document specifically addresses fireproofing in process units, especially structural supports and related equipment (such as tankage, utilities and relevant off-site facilities). It does not address fire prevention (which is addressed in API 2001) nor fireproofing of buildings.
Fireproofing is a complex subject; and API Publ 2218 is not a design manual. As a guideline, it doesn’t specify fireproofing requirements applicable to particular units or plants.It should help site management understand fireproofing issues and help them define protection needs and facilitate effective relationships with fireproofing experts, material suppliers,and installers. This publication assists in the evaluation of options available, and where and to what extent fireproofing might be applied to mitigate the effects of a severe fire.
This publication applies to onshore processing plants.Where comparable hazards exist, and to the extent appropriate,it may be applied to other petroleum properties that could experience similar fire exposure and potential losses.
