10.0 CONTAMINATION REDUCTION PROCEDURES

When exiting the EZ, personnel shall be aware of and follow the procedures used to decontaminate personnel, equipment, and sampling containers. Subcontractors shall ensure that their employees follow proper decontamination and waste disposal procedures. Disposal of PPE and other items shall be performed with material placed in appropriately sized and labeled containers. Specific decontamination procedures are presented in the following subsections. All decontamination procedures shall be in accordance with the Entry/Exit Procedures of NYS Industrial Code Rule 56.

10.1 EQUIPMENT

Since equipment decontamination is difficult, unnecessary equipment shall not be brought into the controlled areas. All materials used in the EZ shall be properly HEPA vacuumed and wet-wiped before leaving the decontamination zone. All equipment that becomes "grossly contaminated", will require an Alconox wash and tap rinse.

10.2 PERSONNEL

Personnel entering containment shall follow proper decontamination procedures as outlined below.

• All employees shall remove all gross contamination and debris from disposal protective clothing and equipment by vacuuming prior to leaving the EZ. • All employees must be HEPA vacuumed before entering the CRZ. • Upon entering the CRZ, each employee shall remove the first layer of protective clothing and place it in the appropriate container. If the employee performs duties and becomes "grossly contaminated", the decontamination procedure will include an Alconox (soapy) wash and a tap water rinse of the outer suit, gloves and overboots prior to removal of the outer layer. • After the employee removes the first layer of Tyvek and gloves, he/she shall then move into a second decon area where the second Tyvek and gloves shall be removed and placed in the appropriate waste container. After this decontamination, personnel shall proceed to a washing facility to take full showers. • The employee shall dispose of all protective clothing upon exiting the decontamination unit; all half-face APR respirator cartridges, if used, shall be changed out, as needed, but on a daily basis at a minimum. Full-face PAPR cartridges may be utilized more than one day if functioning as designed and sealed and decontaminated after each use.

If additional decontamination steps are necessary, these steps shall be performed and documented by the CSO.

Respirator Maintenance Procedure:

1. All respirators will be cleaned, sanitized, inspected, assembled, and maintained ready for use on a daily basis. 2. Each respirator will be stored in a clean and sanitary container. 3. Prior to use, the wearer will inspect the respirator, including the valves, valve covers, nosepiece, straps, eyepiece (for fullface respirators), face piece and its snaps, cylinders, and canisters to insure that the respirator can be worn.
