Well, let's take a hypothetical more nearly realistic where I live. I'm in a one-story office building surrounded by a parking lot. My office is on the outside wall, and the one window in my office cannot be opened. There is an earthquake, and as as a result of the quake, the interior walls have sprung off-center, and my office door won't open. It's jammed shut with me in the office. No phones. No power. No one comes to rescue me. I throw my office chair at the window, and the chair bounces off. I look around the office. The ceiling is acoustical tile, but it's nine feet high, and my office furniture is that flimsy crap that hooks onto the wall so I can't stand on it or climb it to reach the ceiling so that I could climb out into the interior of the building through the ceiling. I'm not sure I'd want to, but I can't. I look around the office again. "Where's my Biel tool?" I cry.

The smell of gas wafts into the room.

1. Possibly free the jammed door by taking a pen, or metal letter opener (or that 16d nail you've got secreted in your desk) and removing the hinge pins, using your shoe or other implement as a hammer.

2. If your interior office walls are constructed of drywall, or other penetrable material, use your stapler, or your shoe ? or your fist if you're feeling macho ? to punch a couple of 4-inch or so staggered holes in the wall, up to the ceiling. Four or so holes should do it. The idea being to create hand- and foot-holds to climb the remaining few feet to the ceiling (after standing on your chair, or inverted wastebasket, which will get you started a few feet off the ground).

This would work best if the holes were located alternating on either side of one of the (presumably) metal studs, located by tapping wall with fist. Just to be on safe side, avoid locations/studs in-line with electrical wall outlets.

This is where that time spent on the climbing-wall at your health club pays dividends. <img src="/images/graemlins/grin.gif" alt="" />

Edit: It occurs to me, too, that if your walls are easily penetrable (drywall etc), you could simply (?) use your chair or other improvised tool to nibble a 2-ft. or so hole in the wall, through to the outer hallway, or adjoining room.

Better yet, where's my shotgun?

I was raised in the country and had shotguns, rifles, pistols, and the thought of pulling the trigger on a shotgun in my office makes me cringe. I have no _clue_ where all the glass would go, where the shot would go in the parking lot, nor how loud it would be.

So let's try it!

People think that the crowbar that used to live in my desk was just for intimidating computers with. <img src="/images/graemlins/smile.gif" alt="" /> I'd attack the moulding of the window at that point, or try to force the door.

I have no experience of earthquakes... I'd have thought the window glass would break before the walls.

If you look at news photos of earthquakes in towns, you'll see lots of buildings have fallen off their foundations with the exterior walls still square and windows unbroken. For some examples:

Another apt building with a garage under the living units:

note the crushed cars sticking out. Windows still intact in the building, though. :-)

Here's the interior of a building after a quake:

and here's an outside office with windows intact:

Photos from the recent Pakistan earthquake shows buildings with almost complete internal collapse, with exterior walls and windows more or less intact:

It's all disaster, and you never can tell what will break and what won't.

Some windows aren't glass at all, but acrylic. I would hate to have to go through THAT!

I heard that movie windows are made from sugar -- nothing is what it seems to be...

First, I should disclaim I don't have any first hand experience with this, although I've given it a bit of thought.

So, a couple of thoughts:

In Craig's original post, he indicated his building was an older 3 story building. I think this is unlikely to have anything too crazy in it. I'd bet the worst you have here is fairly ordinary laminated glass.

I think you should give up on the punch idea. I think you want a decent sized crow bar, hammer, Biel tool, carpenter's hatchet. All of these are going to be much more effective than a chair or bat and much more than a punch. Considering you are talking about your office, this seems like it should be doable. You could stuff a crow bar behind your desk, or do what I do - I have my earthquake duffle under my desk. One of the items in there is a decent sized crow bar. Since it is in the bag it doesn't draw attention.

Someone here posted about the danger of breaking glass and having it fall on you. The poster suggested that you want to break glass from the top with you above it. In the case of an office, this probably means being on the desk and off the the side. I think this also suggests that a longer tool like the crowbar would be better than a short tool like a hammer.

Consider having cut resistaint gloves. I think something like these Best Nitri-Flex Coated Kevlar Gloves would be fairly optimal, but even something like these Ansell ArmorKnit (knit Kevlar) gloves would probably be good (and they can be stuffed in a pocket) - available with "dots" or not. They are also fairly heat resistaint and might come in handy during a fire.

With normalish laminated glass I suspect you could break through it with an impact implement like a crowbar and cut it with a sturdy knife *if* you have protective handwear. Knife will probably be in bad shape afterwords, but should work.

Something like a hatchet would probably work best for cutting through the laminated glass, but I wouldn't want to break a big peice of plate glass with a hammer or hatchet that would place my hand right in the path of the glass.

I think the biggest problem is not knowing what kind of glass it is before it becomes time to find out. Laminated glass should be fairly safe to break, but you will need something to hack/cut through it. The plate glass could seriously injure you as it falls and you probably want as long of a tool as possible.

As such, I would suggest you assume it is going to fall in big, sharp, dangerous peices, but also make sure you have the tools in case it is laminated.

I think defeating the "super" glasses probably isn't a big deal because my guess is they would use them in applications where having the window open won't be of much use. Think highrise.

Another thing to keep in mind is danger to people below as you break the glass.

Oh, in regards to the punch tool for escape from an auto, I think I'd rather have a small (~12") crowbar, sturdy knife and a pair of gloves. A lot more versitile. I have such a crow bar accessible in my car. The main think you need to consider is that it doesn't become lost in the impact. So you'll need to strap it down in a serious way.

And yet one more thing. Thinking about this, I think the Biel tool may be one of the most flexible all-in-one tools for this type of thing. You can impact with it, it extends for a longer reach, and it has a hatchet like head to cut with.

In regards to the acrylic window, probably the best bet would be to pry it out of it's frame. For that, you'd probably want a full size Hooligan tool.

Biggzie,

The plan is everyone gets out the best they can and assemble in the parking lot. Our fire person for our company office has an old fire axe in the computer room for him to break out his office window if there is a fire. We have two exits. The closest door tends to stick and I could see it geting stuck with a temperature change from a fire. The other exit is about 200 yards away. There are windows that could be used for exits, if they could be broken.

I keep goggles, a dust mask and water in my cube for an office emergency. I'd like to think I could create an exit for myself and fellow office workers if there was a fire or emergency.
