Emergency Response, Decontamination, and Medical Surveillance
Emergency response
Emergency response at a waste site requires a written emergency response plan covering pre-emergency planning, personnel roles, lines of communication, emergency recognition, safe distances, evacuation routes, decontamination, and medical treatment. Key distinctions: evacuation (leave the area) versus shelter-in-place (stay inside, seal openings). Emergency response versus post-emergency response - post-emergency operations (cleanup after the emergency is controlled) follow different requirements. Workers who respond to emergencies must be trained to the appropriate level; those who only evacuate need an evacuation plan and alarm recognition.
Decontamination
Decon protects workers, the community, and equipment. Methods include physical removal (brushing, wiping), chemical removal (soap and water), and disinfection; the decontamination corridor lies in the CRZ. Emergency decon must be available before entry begins - a rapid, gross decon capability for injured or contaminated personnel. Decon water is itself a waste stream and must be contained.
Medical surveillance
Medical surveillance is required for workers who are or may be exposed above limits, who wear respirators, or who work on hazardous waste sites for specified periods. Components include baseline examination, periodic exams, and exit examination. Medical records must be kept and made available; confidentiality applies. Injuries and illnesses must be recorded and reported.
Traps in questions
- Confusing evacuation with shelter-in-place.
- Assuming emergency decon can be set up after entry begins - it must be ready first.
- Forgetting the exit medical examination requirement.
- Treating decon water as ordinary wastewater rather than a contained waste stream.
Rule of thumb
Before anyone enters the hot zone, ask: is emergency decon ready, is the emergency plan communicated, and is medical surveillance current? If any answer is no, entry does not proceed.
