Site Health and Safety Plan 19133 East Liberty Road, Clements, California August 16, 2022 Page 32 Sharp Environmental Technologies, Inc. 10.3 Decontamination Procedures Decontamination procedures will be implemented as necessary by the SHSS to protect personnel from hazardous substances that may contaminate and/or eventually permeate protective clothing, respiratory protection equipment, tools, vehicles, and other equipment used onsite; and to minimize the transfer of harmful materials into clean areas; to prevent mixing of incompatible chemicals; and to protect the community by preventing uncontrolled transportation of contaminants from the site. 10.3.1 Personnel Decontamination Personnel may encounter potentially hazardous compounds while performing work tasks. If so, decontamination needs to take place using an Alconox wash, followed by a rinse with clean water. Standard decontamination procedures for levels C and D are as follows and take place inside the Contamination Reduction zone unless otherwise noted: • Equipment and tool drop inside the exclusion zone; • Boot cover and outer glove wash and rinse inside the exclusion zone; • Boot cover and outer glove removal; • Suit wash and rinse followed by suit removal; • Inner glove wash and rinse; • Respirator removal; • Inner glove removal; and • Field wash of hands and face inside support zone. Workers should employ only those steps that are applicable with level of PPE worn and extent of contamination present and the SHSS will provide site-specific guidance on the required decontamination procedures. The SHSS will maintain adequate quantities of clean water to be used for personal decontamination (i.e., field wash of hands and face), secondary containment (i.e. plastic tarps) and wash and rinse containers (i.e. buckets, wading pools etc.). PPE, wash and rinse solutions that are contaminated with site hazards will disposed of as hazardous waste in appropriate containers. Non- disposable items may need to be sanitized before reuse. Each site worker is responsible for the maintenance, decontamination, and sanitizing of their own PPE. 10.3.2 Equipment Decontamination In certain circumstances, field equipment and vehicles may require decontamination as follows: • An equipment decontamination pad or area shall be designated for cleaning large equipment; • All sampling devices will be decontaminated by scrubbing or wiping a decontamination solution such as Alconox and water on the device. A clean water rinse shall be applied; • Tools that are difficult to decontaminate will be kept in the exclusion zone and handled only by workers using the appropriate PPE; • Following decontamination of equipment using steam cleaning, a final steam/water rinse shall be applied;
