Time till body shuts down

[TACKERDOWN]

I could Google it but its better conversation on here. How long can one work in an attic at this temperature. I didn't I went back the next day, I'm not young dumb and full of beep anymore.

133 minutes sounds like a good answer.

I dont blame you.

Even a young guy shouldnt be up there with out a buddy system of some sort.

The roofs get that hot and when August rolls around we schedule our service calls to make sure we're off the roofs in the hottest part of the day.

Wimp!

This afternoon I was changing a blower motor in an attic.
I had my 20" high velocity fan blowing air on me, but it shut off on thermal overload, so I got curious and set a thermometer out where it was protected from radiant heat from the roof deck.
The air temperature was 138º.

We pretty regularly work in attics that are that hot, or hotter, 150º isn't unusual.
Makes those all day installs really fun.
Any day where you are going to where it is "only" 100º to take cool down breaks is probably not a fun day...

Hmm, that reminds me, I need to go buy a new fan, mine has some play in the shaft, which I suspect is why it gave out on me today.
So sad, that fan has been my lifeline in attics for close to 10 years.

That pritty bad when your fan can't handle it. I've never been in a 150 deg. But I used to do attic installs all summer and had some sort of air flow. Maybe I should get a fan. I just don't see it as a good idea any more just to test a system that can wait till the next morn.

133 min that's a good one.

My "next morning" for the next couple of weeks are all booked already.

I suppose that is a good thing though.


I have passed out from the heat once.
The house had a brand new black composition shingle roof that replaced a wood roof. No attic ventilation was added at all, it didn't even have soffit vents.
It was >170º on a intensely sunny 74º day...
I was in the attic for maybe 15 minutes, and passed out as I was taking the last step off the attic ladder into the garage!

The customer complaint was that the heat would come on periodically and blow hot air for a couple of minutes, then shut off.
The problem was that the air temperature in the attic was so hot that it was heating the air in the furnace up enough to make the fan/limit control turn the blower on in the heating speed.

There have been a number of occasions where I found manual reset secondary limits tripped by the attic heat.

Sounds like you might have to do those jobs naked.

I worked in a plant this week that was pretty hot and yesterday I was in a boiler room and air compressor room all day. Working in the ceiling where the heat collects.

I didnt feel good yesterday morning but went to work anyways and spent all day working in that heat with "the splats".... running to release the kracken even after just sipping on water or a soda.

I left early yesterday when I finally couldnt take it anymore and when I got home last night both my legs and my side and my back started cramping real bad.

I was just exhausted.....physically wiped out..... I finally made it to the bed at about 7 oclock and when I did I was so relieved that I started giggling.

I think with the "splats" and working in that heat all week I must have dehydrated myself or something....

Im not going to do anything this weekend if possible.....no yard work...nothing...

I also might go lie back down after I take my medicine and finish my morning coffee.

It never ceases to amaze me why in the world we set air handlers and furnaces in attics. They don't take up that much space in a garage or closet.

Got to go change out an evap coil in an attic.

I never had that happen here in PA.

They wouldn't fit in most garages around here . that would take up space for the golf bags that never get used .

HVAC is the very last thing they try to accomodate when laying out plans.

And the first thing they'll whine about when it doesn't work right. Go figure.

I need to drink 2 - 3 gallons of water a day to stay properly hydrated.

When your fan quits you and says " it's so hot up here....I'm out" maybe it's time to get out of there.

Lol.... your the guy complaining about the widow makers right ? You guys are crazy. Why not invest in a cool vest with extra packs.

Ive had a mild heat stroke before and its not fun. By the time you realize your in trouble its too late. Luckily there were guys around me that got me cooled down and to a hospital.

98 degrees in Houston with about 89% RH that day. I couldnt tell them what day it was or what year it was (i dont remeber any of it ) aftrr coming off a roof with black rubber sheets used as roofing material.
