Which type of EMS personnel is untrained in using specialized chemical protective clothing?

The correct choice identifies EMS personnel who have not undergone training specific to the use of specialized chemical protective clothing. Haz-Tac training equips emergency response teams with the knowledge and skills to properly don and use protective gear when dealing with hazardous materials. Personnel trained under this curriculum are prepared to safely engage with chemical incidents while minimizing exposure risk.

Advanced Life Support (ALS) and Basic Life Support (BLS) personnel focus primarily on medical emergencies and patient care rather than hazardous materials response. BLS personnel, in particular, operate without the specialized training in handling hazardous environments and protective equipment, limiting their capabilities in chemical exposure situations.

It's important to differentiate between the varying levels of EMS training: those with Haz-Tac training are specifically educated on the risks and protocols associated with hazardous materials, while others typically do not receive this training and would therefore lack the requisite skills to utilize specialized protective clothing in potentially dangerous situations.
