Title: Fire Egress required from loft?
Post by: NM_Shooter on December 09, 2007, 03:37:29 PM
Greetings!

I have a question for you..I am planning on a 16X24 cabin, with a loft over the back half.  Does the loft require a fire egress window?

Thanks,

Frank

Thats a really great question I do not have an answer for.  :(

IRC2003 states that "every sleeping room shall have at least one openable emergency escape or rescue opening".

IRC2003 section R310

Now by not placing a closet in such room, the room is designated as something else, yes?

Probably, technically.

But in good conscience I couldn't place any my family members in a room to sleep/live without a secondary emergency exit, or rescue access. Even those I may have issues with.  ;D

I believe this may be a case where I have no fault to find with the regulations.  :o

Most Loft contain at least one window.  They would be pretty dark if they didn't. Would an escape ladder that you through out the window be OK.  Of course open the window before in case the fire was a false alarm.

A local window supplier or a window catalog will note which windows are suitable for code egress. Yes, a throw out ladder would be a very good safety feature on a window you wouldn't want to jump out of.

Don't play code games here... if you ever had some kids caught up there in a fire or other emergency you would have a hard time forgiving yourself. Any sleeping room should have two ways to get safely outside. Period!

PS - An egress window is actually designed as much for a fireman to get in as for you to get out. (He carries an air tank on his back.)

Wasn't trying to offend. Was joking with the evil in law comment. However I was suggesting that if there is no closet the room can be designated for something else like storage. Or maybe a play area (no sleeping). I was not clear in the expression process, sorry about that.
Title: Re: Fire Egress required from loft?
Post by: MountainDon on December 09, 2007, 06:52:53 PM
Well, myself, if the space is anything but a storage area I'd have an opening "just in case". Fires don't just break out when you're sleeping. If the space is used for play, study, meditation, it should be provided with access/egress as far as I'm concerned.

You didn't offend me Stinkerbell. There is no greater scofflaw than me, when it comes to stupid or non applicable building codes. I do need a kick in the butt for safety once in a while and John does it well. My comment was more a thank you...to him. than a post on your question.

Post by: NM_Shooter on December 09, 2007, 08:04:04 PM
Thanks for the replies...

I had planned on putting in a window, but was trying to figure out how big it might need to be.  The loft I am planning does not have a lot of room, and a 2' X 2' casement window was what I was planning on.  May have to go bigger though, as I think this would be a good place to err on the side of caution.  I would bet that a 2020 window is not big enough for large people to qualify as an emergency egress.

BTW...The closest fire truck would be 2 hours away, assuming it was light out and no mud (fat chance). 

Anybody know the minimum size for an egress window?

Thanks,

Frank

well, what do you know.  I can google:

http://www.rd.com/content/openContent.do?contentId=18086 (http://www.rd.com/content/openContent.do?contentId=18086)

That is a pretty large window, even using the casement.  I'm going to have to consider this a bit more.  I wonder if I could make a smaller window in a section of a wall panel that drops away... Problem with that:

What if wall section sticks?
What if kids are not strong enough to release the panel?
No access from outside.

Hmmmm.

Why not use a hayloft style door. You can latch it from the inside and it will just swing open. Believe me, if the FD wants it open, they can open it. c*

NM is the 2020 size set in stone.  Who would ever know if you installed a 3030 or bigger and dropped it down a little in the wall. If you are going to use this as an egress then the style window should also be looked at.
Title: Re: Fire Egress required from loft?
Post by: desdawg on December 10, 2007, 08:47:04 AM
I think an open loft is one of the last places I would want to be during a fire. I hadn't really thought about it before.
Title: Re: Fire Egress required from loft?
Post by: CWhite on December 10, 2007, 09:22:03 AM
This is a little off topic, but for rural living, you have to be your own fire house really.  If there is a fire, you have to get you and your family out safely without help.  A fire escape is not too much to ask, even if it's a jump from a window to a porch roof, and then to a rain barrel, and down.

From the "burned out houses" that I've noticed for many years, it seems like a built in sky light is the most effective way to make sure the house burns up quickly and dramatically.  Those things become chimneys after they melt or break out, and the rest is just a matter of minutes for the fire to do the rest. 

I had sky lights in a house once, and I'm glad I don't now.  I do have fire escape routes from the windows to roofs outside.
Just a thought.

Even though the house I am building on the Oregon coast gets fire protection from the local dept, I am going ahead and installing a fire suppression sprinkler system.  I would think that for a cabin that is way off the beaten track, this would be even more important.  For most of us, the country homes or cabins are not that large so one wouldn't need that many sprinklers to cover the rooms and lofts.  Just sayin...
Title: Re: Fire Egress required from loft?
Post by: NM_Shooter on December 10, 2007, 12:25:55 PM
Hi.. thanks for the replies.  I think this is an important topic.  I am going to have two lofts, one in the back of the cabin, and the other over a large porch.  I am redesigning the pitch of the roof to accommodate a casement style egress windows.  Each loft will have a permanently mounted rope ladder in a box under the window sill.  I tend to be paranoid about stuff like this.

This cabin is going to be extra deep into the wild.  No utilities, no effective way to do fire supression in a low cost way.  I'll have several extinguishers handy, but if it catches, so be it.  My dad was a fireman, and stories about folks darting back inside to retrieve something almost never have happy endings. 

Frank

P.S.  Check your smoke detector batteries.

You can put a little porch off of the window/door and definately use a sprinkler system even if it is just a hose and a sprinkler you can turn on at the faucet I don't know why every house doesn't have some sort of sprinkler system and every upstairs room, loft or whatever should have outside access and you can open the windows in the summer to cool the place down.  There have been several fires in our area over the past several years and they all have one thing in common, minutes and even seconds count!!!  Don't forget several working smoke alarms and fire extinguishers on every level too.  I have a friend who lost everything and they were all home enjoying a big dinner with family and friends the entire upstairs was on fire and no one even noticed until embers were falling on their heads.  They barely got out with their lives.

CPVC plastic can be used for sprinkler systems.  Here's a start on info.

My only source of pressurized water is a 4 gallon per minute RV pump, fed by a 40 gallon water tank.  Those pumps barely put out enough water to run a sink, let alone a fire supression system.  If my extinguishers don't put the fire out with a 10 second burst, I am scrambling out of there.  If 4 extinguishers don't get it under control, 4gpm of water is going to be of no use.  I don't have a way to do a cistern. 

The biggest danger is inhalation, which is the worst up in the lofts.  Smoke detectors are cheap, So I'll have several.  I think that the best practice for this is fast egress, and good insurance.

I believe that given the remote mountainous forested site there are two types of fire to be concerned about. A fire that starts within the structure and the threat of wildfire from the surrounding forest. NM_Shooter/Frank, if the forest in your location is like mine it has too high a concentration of fallen trees, branches, needles, etc. Myself, I feel the threat from outside the cabin is greater than that from within the structure.

We spent most of our time this summer/fall clearing out all the crap on a good size chunk of the property. There's still a long ways to go, but the area around and close to our building area is quite clean. It's not only safer now, but looks better.

I do not have a high volume supply of running water either. At present I have a couple of 2A10BC and one 4A80BC chemical extinguishers up there. As well I have four 2.5 gallon pressurized water extinguishers I bought at auction for pretty good pricing. The problem with the water type is they freeze in winter.

Post by: NM_Shooter on December 11, 2007, 12:04:07 AM
Don... that is a good point.  I was thinking of sheeting the exterior of the structure with OSB, and then covering that with the concrete hardi-board material that sort of looks like T111.  It is supposed to be very weatherproof (important since winters provide 8 to 10 feet of snow) and fire resistant.

Title: Re: Fire Egress required from loft?
Post by: MountainDon on December 11, 2007, 12:44:26 AM
For the exterior with fire resistance in mind there are a few things to remember. If you're building a post/pier unit with the cabin elevated somewhat the first step is to use something non flammable for the "skirting".  I was told that wood skirting or no skirting is the prime place for a fire to catch a cabin. That came from a couple of rangers. I'm thinking of using either rock or metal for that. The roof will be ribbed metal, the skirt could be done with the same.

Clearing away all flammable ground cover will greatly assist of course. Remove the top layer of needles.

Overhanging eves can give fire a place to get a toe hold, number two place for catching so I've been told  Metal or something non flammable is a good bet there.

I've thought of using hardiboard or hardiplank. I'm not sure I'm sold on it aesthetically speaking. I would like something that gives real wood tones rather than a painted surface.  ??? Not certain what the exterior walls will be yet.

One more thing about combustible surfaces that could be exposed to flame. There are intumescent paints available. Good if you like/want a painted surface, instead of a natural or stained wood. Intumescent paints and intumescent paint additives, expand when exposed to direct flame, forming a "char barrier" that lifts off the substrate. They could be used inside or outside.

Also available are foam fire suppression systems. I know of one system that does not require water or electricity. When activated it sprays a fire retardant foam through a pipe and nozzle system. It's out of range of my present budget. It can be manually activated, activated by telephone code or activated by a wildfire sensor system.  [cool]  Info here.

Fire safety is well worth thinking about. And we do all have that charged up fire extinguisher close at hand, right?
Title: Re: Fire Egress required from loft?
Post by: tanya on December 11, 2007, 07:25:28 AM
I find large garbage plastic garbage cans make a good water storage tank (not drinking water though) but they hold a lot of water and they don't take up much floor space so they are easy enough to keep warm, rain catchments can work to catch the water or when wore comes to worse you can fill them with snow to melt.  If you put them up in the loft you will have gravity flow.  And if you have a generator a small electric pump isn't to expensive.

Post by: peternap on December 11, 2007, 11:00:30 AM
Don, I've sprayed outside wood with a Boric Acid/water mix before to make it fire retardant.

I HAVEN"T ever tried burning it so it ,ay well be one of those RURAL LEGENDS ???...What are your thoughts?
Title: Re: Fire Egress required from loft?
Post by: glenn kangiser on December 11, 2007, 11:12:22 AM
I haven't tried the boric acid retardent but have a 5 gallon bucket of borate powder for treatment -- maybe I will try to do a check on that.  Loghomestore recommends a waterproofer such as Defy over the borate or water will remove it.  Great for stopping mold and bugs.  I heard it had fire resistive qualities as does sodium silicate.
Title: Re: Fire Egress required from loft?
Post by: MountainDon on December 11, 2007, 04:33:25 PM
I think we need someone to do a test.  8)I'd volunteer but it wouldn't be too practical, or accepted here in the suburbs.  ;D Might try it in the mountains over Christmas break if there's enough snow on the ground to make it safer.

Do you have recipe; how much water to borate/borax (whatever is used)?

Title: Re: Fire Egress required from loft?
Post by: peternap on December 11, 2007, 06:29:41 PM
I'm not very scientific with it Don. I just add water until it will run through a sprayer.....Funny how I came up with it. I had a rifle that was bad about burning patches with hot loads. I called the Fire Marshall to see if he could think of a way to fireproof them. It was his idea and it worked on the patches so I tried it on wood.

My building inspector had 2 issues with my loft. Fire escape and code stair access IF it was a sleeping/living loft. That made mine a storage loft. I may have to store myself up there if I have overnite guests.
