1. General
1.1 Scope
This specification covers the minimum requirements for hand applied or sprayed-on fireproofing compounds, suitable for exterior exposure, applied on cable trays, conduits, structural steel members and equipment supports, all in accordance with the approved manufacturer’s applicator’s manual per paragraph 3 of this specification.
Items not specifically covered herein or in codes, regulations and construction drawings referred to, shall be determined in accordance with good engineering practice and to the satisfaction of Purchaser.
1.2 Standards
All applicable standards as specified in respective paragraphs of this specification shall be adhered to, unless direct deviations are stated.
1.3 Definitions
For the purpose of this specification the following definitions shall apply:
· A fireproofing compound is a coating, which gives resistance to a fire by means of subliming, intumescence or similar.
· "Approved" shall mean approved by Purchaser.
· "Approved equivalent" shall mean of equivalent quality and properties and approved by Purchaser.
1.4 Supplementary Documents
This specification shall be read in conjunction with the various contract documents and the construction drawings issued by Purchaser.
1.5 Certificates to be Submitted to Purchaser
1.5.1 Certificate stating that the applicator is a manufacturer approved applicator.
1.5.2 Certificate of application and performance in accordance with the required rating as per paragraph 2.2 and 2.3 upon completion of the work.
2. Materials
2.1 The hand applied or sprayed-on fireproofing compound shall comply with the following:
2.2 The basic required minimum rating for the fireproofing compound shall be: 2 hours in accordance with the high rise temperature/time curve for hydrocarbon types of fires per UL1709 and/or BS476 Part 20, Appendix D.
2.3 Fireproofing on cable trays, conduits and their supports shall provide protection against direct flame impingement and a temperature of 1100'C for a period of minimum 15 minutes.
2.4 If, and when local codes or regulations are more stringent than the provisions stipulated in this specification, then the local codes or regulations shall prevail.

7.2 Fireproofing applicator shall confirm in writing the soundness and compatibility of steel surface treatment per paragraph 7.1. with selected and approved fireproofing compound.
Applicator may apply a suitable tack coat to ensure the bondage of the fireproofing compound to the substrate.
Once commenced with the application of fireproofing shall mean that the applicator has accepted the steel surface treatment to meet his guarantee towards Purchaser.
8. Quality Control
8.1 General
The fireproofing applicator shall inspect each operation included in his scope of work, such as material receipt, activities prior to and during application of fireproofing.
Purchaser, however, reserves the right to inspect any or all of the operations.
Inspection and approval of materials and/or workmanship by Purchaser shall not be construed as relieving the applicator of his responsibilities.
Reconstruction or repairs to faulty work shall be done after consultation with Purchaser.
8.2 Reporting
Fireproofing applicator shall report in writing on the results of his inspection on the hold points such as: <engineer to complete>
8.2.1 Receipt of Materials
