What additional protective gear may be worn beneath the traffic safety vest if necessary?

The inclusion of helmets, raincoats, or turnouts beneath a traffic safety vest is vital for ensuring the safety and protection of personnel, particularly in active shooter situations or other emergency responses. Each of these items offers specific benefits.

Helmets provide head protection from potential impacts or projectiles, which is crucial in high-risk environments. Raincoats protect against adverse weather conditions that could impair visibility or lead to hypothermia during extended incidents. Turnouts, often associated with firefighting gear, offer thermal protection and durability against harsh conditions while allowing for mobility. Wearing these items beneath a vest enhances overall personal protection and situational readiness without compromising visibility or identification as part of a response team.

The other options do not fit as appropriately for the context of being worn beneath a safety vest. Body shields would typically be separate pieces of equipment rather than layered under a vest. Fire-resistant suits are specialized gear that may be worn in specific fire-related scenarios but are not generally intended to be worn under a safety vest in active shooter situations. First aid kits are essential for medical emergencies but are not protective gear in the same sense as the other choices.
