ES&H Manual

Fire Protection Supplement

Chapter 2:

Fire Protection Design

 

1.0          Purpose

 

This document outlines the considerations that need to be made to incorporate contemporary fire-protection standards, while accommodating the unique features of the accelerator, experimental apparatus, and a variety of associated workplace environments at Jefferson Lab.

 

2.0          Scope

 

This document describes personnel responsibilities, building fire-safety features, construction practices, fire protection systems selection, system acceptance, fire protection water supply, existing facilities, hazard prioritizations and mitigation, fire damage, actual loss determination, and loss reporting.

 

New facilities or major renovation of existing facilities requires a review of any existing fire-protection systems and features within the affected area by Facilities Management.  The design-review process includes reviews by the Fire Protection Engineer (FPE) early in the design phase. These include reviews at the 30-, 60-, and 90‑percent design phase.  These reviews may be conducted on a less frequent basis, depending upon the size of the design project.  Facilities Management maintains all relevant files for each project, including design criteria and rationale.  Design reviews are also done for projects performed by in-house staff, with peer reviews performed for each design. 

 

Additional details regarding the design of new facilities are found in ES&H Manual Chapter 3110 Facility Design and Modification Review.

 

Equivalent means of Fire Protection and Exemption from prescriptive code requirements and DOE Orders are sometime warranted. This document is used to identify existing equivalencies and exemptions granted by DOE.

 

3.0          Responsibilities

 

3.1            Fire Protection Engineer (FPE)

·       Perform building design evaluations.

·       Reviews and approves proposed projects and designs at multiple stages in the design process for compliance with fire protection code requirements and site-specific fire protection requirements.

 

3.2            Supervisors, Building Managers and area Work Coordinators

·       Monitor the activities of personnel within affected areas. 

·       Prevent any alteration to building construction features not coordinated with Facilities Management.

 

3.3            ESH&Q Professionals 

·       Ensure that space use is consistent with the fire safety design.

·       Provide guidance to line management on limitations of potential space use.

·       Participate as required in the planning processes for renovation and new construction.

 

3.4            Facilities Management Staff 

·       Ensure fire protection water supply is adequate for design.

·       Incorporate all applicable codes standard requirements, equivalencies and exemptions into designs for new construction and renovation projects.

 

4.0          Fire-Safety Design Considerations

 

4.1            Building Design Evaluation

Building designs are evaluated for compliance with the traditional construction codes and standards along with several additional considerations.

·       International Code Council Inc. International Building Codes.

·       Site-specific requirements for detection, suppression, life safety, and underground-water distribution described in Fire Protection Supplement Chapter I Site-Specific Requirements.

·       Building features that provide for Highly Protected Risk status or the best-protected class of industrial risks.  This status is achieved through incorporation of design features contained in FM Global Property Loss Prevention Data Sheets.

·       DOE STANDARD 1066-12 Fire Protection.

 

4.2            Fire Protection Water Supply

The City of Newport News provides water for the Jefferson Lab site.  There are three water-supply meter vaults to the site:

·       One 4-inch water meter is on Hogan Drive (north of the facility).

·       One 8-inch water meter is on Jefferson Avenue (west of the facility).

·       One 12-inch water meter is on Canon Boulevard (south-east of the facility).

 

4.2.1       With the exception of the Support Services (SSC) Building area, the site hydrant and fire suppression systems are continuously connected to the Canon Boulevard and Jefferson Avenue underground 24-inch concrete city mains.  This supply redundancy provides a high level of confidence in a continuous water supply for most of the site.  The SSC area is served by the separate municipal water supply.

 

4.2.2       Testing, flushing, or special connections to the water supply system use back-flow prevention precautions as discussed in ES&H Manual Chapter 6730 Water Quality Management.

 

4.3            Equivalencies and Exemptions

 

4.3.1       Equivalency - Common Path of Travel for Injector Area, Approved April 8, 1998 to exceed the maximum 100ft distance for common path of travel [in an area protected by automatic sprinkler systems] by 15ft for the injector area of the tunnel enclosure.

 

4.3.2       Equivalency - Manual Pull Stations, Beam Enclosure, Approval letter from Barbara Morgan to Bill Rust dated April 21, 1995, permission to deviate from stations @ 200 foot intervals to stations @ 600 foot intervals.

 

4.3.3       Equivalency - Fire Sprinkler Protection for Experimental Hall’s A,B,C

Approval Letter: September 27, 2010.

 

Compensatory Action Required:

·       Implement a comprehensive and rigorous Combustible Control Program - On February 8, 2011, Chapter 11: Combustible Loading supplement was created to develop a method to actively control the accumulation of transient combustible material in the Jefferson Lab experimental Hall’s and the Accelerator Tunnel. Weekly inspections are conducted by the FPE and documented electronically as well as hard copy.

·       Provide further evaluation of the need for additional suppression at the ceiling level in Hall B - Currently in the process of evaluating what type of system best suites Hall-B’s needs in conjunction with the upcoming experiment.3.

·       Install flammable gas detectors at locations where flammable gases are used - Currently in the process of evaluating the most up-to-date VESDA gas detection equipment to install in line of the existing VESDA piping.

·       Maintain the existing active and passive fire protection features. Specifically fire barriers, fire doors, sprinkler systems, VESDA, fire alarm and smoke removal systems - Inspections are conducted per NFPA throughout the Jefferson Lab site by outside contractors.

·       Continue to have a qualified fire protection engineer serve on the experimental planning committee - Both the Fire Protection Program manager and the Fire Protection Engineer review all operational safety procedures and serve on the experimental planning committee.

 

4.3.4       Equivalency - Request (NFPA 101) Equivalency, Accelerator Tunnel Ramps, Approval letter February 4, 2008.

 

Compensatory Action Required:

 

1.     The proposed design and facility operations shall include the following additional safety controls:

 

Engineered Controls:

·       Fire Detection system for early warning.

VESDA has been installed in the tunnel extension.

·       Fire Suppression System.

Dry sprinkler system has been installed throughout the tunnel extension.

·       Non-slip surface on the ramp.

Concrete floor was left in rough surface condition.

·       Lifting eyes in the ceiling above the ramp to aid in material handling along ramp.

Lifting eyes have been installed throughout tunnel extension.

·       Emergency Lighting.

Emergency lighting has been installed per NFPA requirements.

 

Administrative Controls:

·       Restricted access to able- bodied personnel.

CANS will be installed for access control.

·       Posted exit signs.

Exit signs are installed throughout the tunnel per NFPA.

·       Personnel training.

SAF-113KD (Hall-D Conduct of Operations) training incorporates Hall-D and the tunnel extension into it’s program.

·       Task hazard analyses of activities in the tunnel extension.

Task hazard analyses are conducted and approved before work moves forward in the tunnel.

 

2.     A change in the facility operations from the proposed scope of work voids the equivalency approval.

No plans at the present time to alter the scope of work.

 

3.     A change in the hazard classification within the specific area voids the equivalency.

No changes in the hazard classification in the specific area anticipated.

 

4.     Future revisions of the facility FHA’s are to maintain a copy of the TJSO equivalency approval documentation and supporting JSA information within an attachment.

All FHA’s from this point forward will have equivalency documentation incorporated into the FHA package.
