10 PERSONAL PROTECTIVE EQUIPMENT Based on the hazard analysts for this project, the following Personal Protective Equipment (PPE) will be required and used Changes to these specified items of PPE will not be made without the approval of the SSO The minimum required level of personal protection on the site at all times is level D Level D consists of hard hat, safety glasses or goggles, steel-toed boots, work pants and shirts with long sleeves (or coveralls), and nitrile gloves Ear plugs will be worn if, at any time, verbal communication becomes difficult to comprehend within a radius of three feet. Hard hats, safety glasses (goggles), and safety shoes must meet American National Standards Institute (ANSI) approval If Level C protection is required, it will consist of Level D protection listed above, plus Tyvek coveralls, nitrile gloves and liners, chemical-resistant safety boots, and full-face respirator with combination organic vapor and high efficiency filter cartridges Contact lenses will not be permitted on site If at any time throughout the course of this ,lob, there is a potential for increased exposure to the personnel, the appropriate upgrade of personal protective equipment will be required Use of level B PPE is not anticipated ENVIRONMENTAL MONITORING PLAN The potential hazards identified in the hazard analysis portion of this SSHP determined the need for initial and/or ongoing monitoring for assessment of exposure to the hazards as follows. The direct-reading instrument that will be used to monitor air quality in and around the work areas is the Organic Vapor Monitor(OVM) The OVM measures the total organic vapors present in the ambient air For health and safety purposes, total organic vapors detected will generally be used to confirm the selection of protective equipment The OVM will be calibrated prior to each day's activities using 100 ppm isobutylene to air as the standard. Air monitoring for background levels of air contamination upwind of the protect will be performed prior to the start of field activities. Monitoring with the OVM will be conducted a minimum of every 15 minutes At any time the OVM reading shows a sustained concentration greater than 50 ppm, air-purifying respirators will be worn by all personnel at that work location. If at any time during field activities, the OVM reading at the breathing zone reaches or exceeds 100 ppm, work will be discontinued and field personnel will move away from the area until lower organic vapor readings are obtained If OVM readings indicate consistent organic vapor concentrations greater that 100 ppm, then work will stop and the level of PPE will be re- evaluated by the SSO to conjunction with the PM and HSD Heat stress, cold stress, and noise will be monitored as described in the hazard analysis portion . of this SSHP WIN94ZA9017 M 30NORTHARG4 QMS PS410
