frequently changing personnel the current site conditions and the work and hygiene procedures that are necessary to protect their health and safety.

2) The written HASP should include how the following issues arc being managed. These items arc based on required elements of the OSHA Asbestos and Respiratory Protection Standards.

a) TrIVOsure Monitoring - Currently only area monitoring around the perimeter of the NYPD work area is conducted by EPA. FBI is conducting personal .j •1 monitoring weekly. Procedures for personal exposure monitoring of NYPD personnel should be implemented as part of an Exposure Assessment Plan to document actual NYPD exposures and verify that appropriate work procedures are being employed. It is anticipated that individual exposures will vary according to factors which include the job being performed, weather conditions (wind and rain), the source of the debris (lower floors of the WTC are noted to contain more asbestos than the higher floors), etc. In addition to asbestos, provision for monitoring of other potential site contaminates should be evaluated during HASP preparation.

b) Task Hazard Assessment - Comprehensive evaluation of all the tasks being conducted by the NYPD and a detailed listing of potential hazards and means and methods to control those hazards.

c) Site Control - Access to the debris fields where raking is taking place should limited to ycrsonttcl weariness, rprgcctjve equipment and rn~ g- Warning signs should be posted at entrances to each area.

d) Use of Respiratory Protection - The following elements are necessary in order to ensure the effectiveness of the respirators that arc being used: i) Selection - Respirators used in the debris fields should be limited to tight- fitting half-face or full- ce res irators. The use of filtering-facepieces (dust masks) of any t unless it is shown that asbestos levels to that person in that job are consistently below the OSHA PEL. ii) Training - The training which was observed included instructions on how to yl;,yt put on the respirator and how to perform a positive and negative pressure "fit- check". Typical respirator training also includes why a respirator is necessary; how improper fit, use, or maintenance can compromise the protective effect; capabilities and limitations; maintenance and storage procedures; and how to inspect the respirator. Additional training is necessary. iii) Fit-Testing - Instruction was provided on how to perform a Positive/negative pressure "Fit-Check". Fit-testing, procedures which evaluate if.a person has en effective seal between the respirator and their face, was not conducted. Qualitative fit-testing rests an individuals ability Co smell, taste, or otherwise
