For those of us not up to speed on terminology, what’s “green tag” ?
I’m assuming it means some kind of minor injury not needing transportation?

Ive heaard of EMS box alarms but was told thery were done away with. What is included in an EMS first alarm? If that terminology is even right.

The Wake County EMS System recently implemented alarm levels, and we haven’t had a chance to post about it yet. Information forthcoming.

Under triaging there are generally four types of patients-
Green – aka Walking Wounded, Minor Injury or Illness, Non Life Threating, can be transported via bus or mass transit if needed.
Yellow – Intermediate (NOT EMT-I), Have injuries or illness, but can wait untill the most life threating are treated.
Red – Immediate, Life Threating Injuries, 1st Care Priorty
Black – Deceased or So Injured as to be consider not viable to use scare EMS resources when that is the case.

Four of six district chiefs at this incident with all pt’s reported as green tags? Sure hope there weren’t any cardiac arrests or other serious calls during that time.

So what exactly was it that caued it?

The AP has reported that the cause was pepper spray placed as a prank on a hand dryer in the men’s restroom, and which spread through the restaurant.

...while the N&O says the substance remains unidentified, http://www.newsobserver.com/news/local_s..

OK, here’s the facts…. It was a top secret government experiment on the effects of mind control coupled with fast food consumption. (Gotcha, right?...) There are two things that can cause a crowd to have scratchy throats and watering eyes in public venue… (provided they are not flopping around on the ground or complaining of a STRONG chemical odor).... #1 is pepper spray and #2 pepper spray.
