1) Where am I? If I have to tell someone to get to me, how will I communicate where I am actually located?
2) Where are the exits? If I have to leave, what options are available?
3) Where are the threats? Can be person, animal, or dangerous environment (wet floor, light about to fail, vehicle, etc.)
4) Where are the helps? First aid kit, fire extinguisher, alarm, phone, baseball bat, etc.
5) What is the plan?
When dining in restaurants, a lot of law enforcement want their backs to the wall and where they can watch people coming and going. Seasoned travelers will count the number of seat heads between them and an emergency exit on planes.
Son’s best friend was a Secret Service agent & when he flew, he was always armed whether for work or personal. He told the story about checking in to fly back to DC & checking in at the counter. He got on the plane and the stewardess came up to him before taking off & said it so everyone around him could hear if he was their armed SS agent on the plane. Said it pissed him off because it made him a target & he wanted to nap. She basically outed the only help she had if something on that flight went south on the crew.
I liked it because whenever he and my son hung out in DC, he was always armed. My son has CC but only for Virginia and that took him 6 months to get & he has TS clearance!!
