APPENDIX F<br />

8.2.3 Equipment Decontamination<br />

Heavy equipment, PPE, monitoring equipment, and sampling equipment may require decontamination.<br />

Procedures may be modified based on actual site conditions or Project requirements. Depending on the<br />

nature of the contaminant, seats and flooring of equipment and vehicles entering an exclusion zone may<br />

need to be covered with disposable plastic such as polyethylene.<br />

Decontamination of heavy equipment (including under carriage, chassis, and cab) will be performed using<br />

a high-pressure washer sprayer, and/or steam cleaner and appropriate biodegradable solvents. All<br />

equipment will be decontaminated on a pre-constructed decontamination pad designed to collect and store<br />

washings. The equipment will first be sprayed and scrubbed with water (and a low-sudsing detergent as<br />

required). Secondly, the equipment will be rinsed with water. If persistent contamination exists after<br />

cleaning based on visual assessment, other cleaning methods may be necessary. Air filters on equipment<br />

used in the exclusion zone will be removed and disposed with the materials used for decontamination if<br />

warranted. Depending on the contaminants, a simple scraping and brushing off of the equipment may be<br />

acceptable.<br />

Outer PPE (such as protective suits, boot covers, and outer gloves) will be washed and rinsed with<br />

trisodium phosphate and water. These items will all be discarded at the end of the day. If they have<br />

become grossly contaminated during work operations, they will be changed as necessary during the day.<br />

Respirators will be sanitized by rinsing in a germicidal rinse followed by a clean water rinse, then air<br />

drying in a clean area.<br />

Each person will be responsible for the gross decontamination of their own respirators at the end of each<br />

shift. A thoroughly trained SHSS may perform respirator maintenance, however all repairs must meet<br />

manufacturers specifications.<br />

Reasonable precautions will be taken to minimize monitoring equipment contamination.<br />

Decontamination will be accomplished using materials that will not damage the instrument(s). Delicate<br />

air monitoring and surveying equipment will be wiped off with alcohol or soap and water and protected<br />

from contamination when in use.<br />

Sampling equipment used for chemical tests will be cleaned following procedures specified in the Field<br />

Sampling Plan (Appendix A) .<br />

If decontamination pads are used, they will be constructed to facilitate containment and collection of all<br />

potentially contaminated water and decontamination fluids. The waste liquids will be transferred to<br />

appropriate drums, holding facilities, or waste systems. All PPE wastes generated will be bagged, labeled,<br />

and stored for offsite disposal or incorporation into other waste materials. The Contractor will store waste<br />

in a manner and in an area designated by the facility. In no case will storage exceed 90 days from the<br />

start date of accumulation of the waste. Some facilities require that storage not exceed a period of time<br />

less than 90 days (e.g., 45 days). Each project manager will ensure that the specific requirements of the<br />

facility are followed.<br />

8.3 Support Zone<br />

The support zone will be arranged considering accessibility, utility availability, wind direction, and lineof-sight<br />

to work. Included in this area will be the main office trailer, administration area, vehicle parking,<br />

security, toilets, water, electricity, and a break/lunch area. The support zone will be outside the<br />

contamination reduction zone and will be the area where support workers will provide assistance to<br />

workers inside the exclusion zone and contamination reduction zone. The support zone normally will<br />
