3 Hazardous Materials Awareness for EMS Free Online FlashCards

What is a hazardous-materials incident?

A release—or threatened release—of a substance that can harm people, property, or the environment.

What is the awareness-level responder’s role?

Recognize a possible release, identify the material if possible, notify the proper authorities, and take no further action to control the release.

What can simultaneous illness near a common source indicate?

Multiple people becoming ill at once near a common source can signal a hazardous-materials release, but it does not identify the substance or prove the area is safe.

How should EMS identify an unknown substance from a safe distance?

Do not approach to read a label, touch a container, or use smell to identify a chemical. Report observations and leave identification to appropriate personnel using safe sources and instruments.

What should EMS do first when a release is suspected?

Stop before entering the affected area. If already close, withdraw by a safe route without crossing the release or visible contamination.

What information should EMS give dispatch about a suspected release?

Report the location, visible clues, known wind or weather, people at risk, and your safe staging location; request appropriate specialized resources.

What do the hot, warm, and cold zones mean?

The hot zone is potentially contaminated, the warm zone is controlled support and decontamination, and the cold zone is intended to be uncontaminated support.

When is the ERG useful, and what does it not replace?

For transportation incidents, use the current ERG to find initial precautions and applicable isolation or protective-action distances. It does not replace incident command, hazmat expertise, or ongoing assessment.

What factors support safer EMS staging near a release?

When directed, remain in the designated safe area. If conditions and command permit, stage uphill and upwind, consider drainage and changing wind, keep an escape route clear, and avoid runoff or vapor.

Do ordinary medical PPE or an ordinary respirator make unknown-atmosphere entry safe?

No. Gloves, eye protection, or an ordinary respirator do not make entry into an unknown atmosphere safe; specialized protection, training, monitoring, and authorization are required.

How can contamination spread during patient care and transport?

Contamination can spread from a patient, clothing, equipment, or runoff to responders, the ambulance, and the receiving facility. Do not load a potentially contaminated patient into a clean ambulance.

When may EMS begin decontamination?

Do not begin decontamination unless trained, equipped, and assigned to do so. Coordinate patient movement and decontamination with hazmat and incident command.
