BE AWARE ALL MAJOR TRAVEL AND SHOPPING CENTRES HAVE MAJOR INCIDENT BAGS.
these bags contain basic medical supplies and ppe for about 300 people.
also every shop/pub/office/resteraunt etc must have first aid kits and fire extinguishers so there is equipment available relatively near by.
just a simple thing but in a mass casualty incident, if you want to help simply shout anyone who can walk follow me, then lead to a safe area and tell them to stay put and help will come.
this will enable emergency services to rapidly see how many people they need to treat as p1 and 2 because they did not move.
Having been in a pub when the first aid kit was produced (drunk man stabbed himself in the hand ((no not threatening or anything like that))
The first aid kit was a old white tin with a red cross with about 5 shrivled up plasters with the glue dry and a partially unwrapped crape bandage....
Larger chain pubs will likely have a half decent HSE kit but the average local pub you'd be better going to the ladies and bunging a few quid in the machine containing feminine products tampons to plug a bullet or knife wound and towels for direct pressure not ideal but clean and sterile
If your roughing it, Your doing it wrong
Lack of planning on your part doesn't make it an emergency on mine
Ah yes....my favourite type of dressings - lady stuff.
Old-style sanitary towels make a good pad for a pressure dressing. Tampons plug a hole fast.
Headscarves are perfect triangular bandages. Hairgrips can keep a bandage in place.
Take another look around you ladies. Even a hairbrush handle can be the winder on a tourniquet.
Be aware of where survivors are being taken, it's not unusual for secondary devices to be placed in the obvious "safe points".
Back in the IRA days I watched the police move people away from a fairly safe large open space and placed then all in front of huge plate glass shop windows, it was only when the ATO (bomb disposal) turned up and had a fit they moved them back. If the device had exploded they'd have been cut to shreds.
