✍️ Sample Emergency Services Questions & Answers
1. What is 'text-to-911' and when should it be used?
Text-to-911 allows people to contact emergency services via SMS when calling is unsafe (e.g., domestic violence, intruder) or impossible (e.g., hearing impairment).
2. What does 'CISD' stand for in emergency services and SAR?
CISD (Critical Incident Stress Debriefing) is a structured group process to help responders process psychological trauma after difficult incidents.
3. What is a 'silent 911 call' protocol?
Silent call protocols allow dispatchers to recognize when a caller cannot speak (e.g., domestic violence) and dispatch help based on location and key-press responses.
4. During mass decontamination operations, which category of patient should typically be decontaminated first?
Non-ambulatory critical patients are prioritized because they cannot self-decontaminate and their inability to move increases the duration and severity of chemical exposure.
5. The 'rule of thumb' technique used at HazMat scenes involves:
The rule of thumb provides a quick field estimate of safe distance: if you can fully cover the incident with your thumb held at arm's length, you are approximately 300 feet or more away, reducing your exposure.
6. The 'hot zone' in a HazMat incident refers to:
The hot zone (also called the exclusion zone) is the area of highest contamination directly around the release point, where only properly equipped HazMat personnel may enter.
