The s presented the pian will apply to all personnel on -rite re�irernents, specin=ons and procedure. including erngsite visitors and regulatory agency penznnel_ KkZ&RD A-NALY I Tne most significant risk associated with petroleum contarninated soil is e.%-posure to aromatic comocunds. Skin contact wiE be eliminated by use of clothing, eye wear, and gloves and Lite inhalation ha ---rd will be mini ri ed using appropriate t7escirator7 protective devices as deterrninned by on-site air monitoring. The Safety Coordinator/Pro}ecz NL-Ur will establish an exclusion zone encompassing a 34- Foo: radius from the work are': access Within this zone will be limited to required personnel. Total or=7nic vapors will be monitored within the exclusion zone using a photoionization derec nor (PID) caiibrated For benzene, the most tota.c of the aromatic hvdrocorbons.
