Q

What are the common routes of exposure for CBRNE materials?

A

Inhalation

Q

What are the Practical Guidelines for Law Enforcement First Responders?

A
  • Limitations of Personal Protective Equipment (PPE) availability and safe use (LE Responders should not use any PPE above gloves and particulate/droplet mask except to escape from a hazardous situation or at the direction of Incident Command)
  • Safe donning and doffing of Nitrile gloves and particulate/droplet mask Instructor Note: demonstrate.
  • Practical decontamination (hand wipes, soap and water, antibacterial gels, antiviral wipes, etc.)
  • Time, distance/direction, and shielding/barriers (Shorter times in a HAZMAT zone are ALWAYS better. Distance and upwind location from a HAZMAT zone are ALWAYS better. Shielding and barriers can be helpful.)
