3.5 FIRE SAFETY

Comply with all fire safety and protection requirements in effect on Eielson AFB. The government shall brief the contractor on these requirements at the preconstruction conference. For installation of fire-suppression systems that are chemical based, contact Air Quality Program Manager prior to purchase to ensure it complies with 40 CFR 82 (SNAP-approved chemical). B. Prior to beginning any welding, use of open flame device, or any activity that produces sparks, obtain a "hot work permit" (AF Form 592, Hot Work Permit) from base Fire Department. The permit shall be renewed each day welding or open flame devices shall be used.

a. If the contract work requires numerous days of hot work, the contractor may elect to have one of his on-site personnel designated as a Permit Authorizing Individual (PAI). The contractor's PAI may issue hot work permits at the work site, thus avoiding the requirement for daily permits issued by the Fire Department.

b. The contractor's PAI shall be the on-site superintendent, a foreman, the contractor's safety manager, or other individual with sufficient knowledge and experience to recognize unsafe work practices or conditions and having authority to stop work immediately if such unsafe practices or conditions are observed. To be designated as a PAI, a person must schedule and successfully complete PAI certification training offered by the base Fire Department. The PAI certification training is estimated to last 60 to 90 minutes and will be valid for the duration of the contract.

c. Fire Department personnel may periodically visit the site to ensure the contractor is complying with fire safety requirements. A PAIs

SECTION 01 73 29 Page 4 certification may be revoked if the PAI has failed to issue permits on days when hot work is performed, or if unsafe practices or conditions are observed.

d. Questions concerning these requirements may be directed to Fire Prevention Office, 354 CES/CEFT, Eielson AFB, 377-1293.

The contractor shall notify the Fire Department at 377-4156 and Fire Prevention Section at 377-1293 a minimum of 72 hours before, and again immediately prior to, temporarily closing any street or building access, interrupting water service to any fire hydrant or interrupting the operation of any fire detection, alarm or suppression system. The fire department shall be immediately notified upon reopening closed areas, restoration of water service to any fire hydrant, or reactivation of any detection, alarm or suppression system. Additionally, any out of service hydrants will be covered and secured with a black bag to easily identify it is "out of service". This notification requirement is in addition to other contract requirements.

Provide a 10 lb, ABC fire extinguisher at all work areas.
