you need plans so that if someone breaks there leg or gets blasted in the eye without protection.
you need to know who is in charge of first aid if it is needed, who the safty driver is to get your injured playerand the person giving firstaid to a hospital.
with piro you cant just start poping of red distress flares (if youve ever worked in ops/trg in meaford you'll know why) contact local police and fire depts to let them know that you will be useing pyro and flares.
safty is a big thing for me have all of your refs carry radios and flashlights when it gets dark. is there a atv that can be used help transport the injured to the safe zone?
