Site Control Program - Contamination Reduction Zone Purpose

The CRZ must be well designed for the following procedures and tasks:

• Decontamination of equipment, Personnel Decontamination System (PDS) operators, personnel, and samples. This is explained in the "Decontamination" unit of this course.
• Emergency response. Emergency response includes the transport of injured personnel (using a safety harness or stretcher), first aid equipment (bandages, blankets, eye wash, splints, and water) and containment equipment (absorbents and fire extinguishers).
• Equipment resupply. As personnel use equipment, it should be restocked. This may include air tank changes, PPE (for example, booties and gloves), sampling equipment (such as bottles and glass rods), and tools.
• Sample packaging and preparation for onsite or offsite laboratories.
• Worker temporary rest area. This may include toilet facilities, bench, chair, liquids, and shade. Water and other potable liquids should be clearly marked and stored properly to ensure that all glasses and cups are clean. Wash facilities should be located near drinking facilities to allow employees to wash before drinking. Drinking, washing, and toilet facilities should be located in a safe area where protective clothing can be removed. Facilities should be cleaned and inspected regularly. Appropriate protective measures should be taken by maintenance workers.
• Drainage of water and other liquids that are used during decontamination. This is explained in the "Decontamination" unit.

Personnel within the CRZ should be required to maintain the following:

• Internal communications
• Line-of-sight contact with work parties
• Work party monitoring (by checking remaining air time of breathing apparatuses, fatigue, heat stress, hypothermia, and site security)
