Would you know what to do if an armed person showed up at your work place? Most of us would not. I know, it's sad we even have to address the issue.If you ever find yourself confronted by someone with a gun, know you are not defenseless. The need to act quickly can be the difference between life and death, so here are some essential things to keep in mind.

RUN, HIDE, FIGHT

There are several things you need to keep in mind. Sure, it’s hard to think in a situation like that, but if you can somehow act fast, these steps just may save your life. The three most basic things to remember are run, hide and fight.

CALL 911 AND KEEP QUIET

Call 911, when you can and know the lock down procedure that may in place in the facility where you are. If approached by the shooter, don’t inform him or her that you have a phone because that may prompt him to go after you.

DON’T LET JUST ANYONE HELP YOU

You don’t want to be duped into thinking someone saying he’s an officer when he is actually the shooter. Also, if you find yourself in a position where you are leading others, tell them to keep their hands exposed, especially over their heads, if possible. Doing so will make it easier to identify the shooter, who will most likely be armed.
