a) Exposure Monitoring - Currently only area monitoring around the perimeter of the NYPD work area is conducted by EPA. FBI is conducting personal it 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 verity (hat appropriate work procedures are being employed. It is anticipated that individual exposures will vary according to factors which include the job being performed, weaker 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.

Typical respirator Gaining 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 perfonn apositiveZnegative pressure "Fil-Chcck".
