One of the MOST important things to remember. Avoid stairs, at all costs. If your workplace has stairs, refuse to climb them and ask your employer to have them removed, and replaced with a ramp or elevator, or better yet, ladders. If there is an emergency and you must descend stairs, take off all of your clothes and your shoes first, most stair problems are caused by clothes snagging on railings, or tripping because of your shoes.
Never, even in an emergency, ascend stairs.if you must move vertically to escape a situation take an elevator, find a ladder, or stand on your desk and/or chair and/or computer and climb through the ceiling (if you have a false ceiling) or ventilation duct.
