When you're a first responder, you need protection. Unfortunately, most first responders go to work each day without the protection they need for their safety. This is especially true with regard to firefighters and paramedics. In fact, many EMS workers are limited in the protection they receive. That's where first responder level 3A vests come into the picture. Level 3A vests give EMS workers the protection they need to stay safe on the job.
