Way back I

:-)

Bicycling really hard in the Summer months leaves me with a *heat* head ache.

:-)

I'm glad I'm not a forrester.

Supposed to get rather warm the next few days here...I just finished all our silo work here...no need to go climbing onto steel catwalks for now...

Walking 14' to my car in >72 degrees does that for me.

From now on I'm blamming any spelling errers I make on the heet.

Drew,


If you've been drinking this stuff, I'd think you have bigger problems than speeling.

I don't drink it (didn't like the flavour and the bottle I had lost all it's carbonation).

Freshness dates are fun!

They allow me to reminisce about where I was in life back when I bought things!

use to post safety bits because I thought of those that may not be exposed to safety programs such as one in certain jobs.
 
I know this is lengthy but some may find interest in it.
LOL...as things and folks can get heated 'round these parts....be safe.
 
HOW THE BODY RELEASES HEAT
Sixty-five percent of the body's heat is released through radiation. This occurs when ambient air temperature is lower than the body's skin temperature. Radiation is the movement of heat energy from a warmer object to a cooler object, such as when heat radiates from the sun to the earth.
Convection accounts for approximately 10 percent of heat loss. Convection is the transfer of heat energy from a warmer object or space to a cooler object or space through differences in density and the action of gravity.
Approximately 23 percent of heat loss is due to evaporation of perspiration from the skin. Evaporation is the cooling of a surface through the process of a liquid changing to a vapor and leaving that surface. Conduction will add another 2 percent to the heat loss total. Conduction is the transfer of heat energy from a warmer object to a cooler object through direct contact.
When the ambient temperature of the surrounding air is 95 F or higher, radiation, convection and conduction stop working. Evaporation is all that is left to cool the body. Protective clothing used by welders, firefighters, racers and hazmat workers will make the heat situation even worse.
A performance study by NASA using telegraph key operators showed that in temperatures of 80 F, the operator will make five errors an hour and 19 mistakes after 3 hours. At 90 F, the operators made nine mistakes per hour and 27 after 3 hours. At 95 F, the mistakes went to 60 in 1 hour and 138 in 3 hours. Although errors made by telegraph key operators may not be critical, this same hot environment will produce a proportional amount of errors regardless of the task.
When a person is in a hot environment, up to 48 percent of the blood is pumped by the heart to the skin for cooling. The first effect is to release heat, but water also is released through perspiration. If an individual loses 2 percent of body weight due to perspiring, that person is considered to be in a heat-exhausted state. A study by Wasterlund and Chaseling¹ placed forest workers in a controlled environment, where one group was properly hydrated and the other group was dehydrated to an extent of 1 percent of body weight loss. The test included the time taken to debark and stack 2.4 cubic meters of plywood. They found a 12 percent decrease in productivity from the dehydrated group.
Another study by Gopinthan et al² focused on mental performance and the effects of dehydration on the decision-making process and could be related to an increase in work-related accidents. The study concluded that with 2 percent of body weight loss, visual motor tracking, short term memory, attention and arithmetic efficiency all were impaired. In the extreme, the study notes that a 23 percent reduction in reaction time occurred with a 4 percent body fluid loss.
WHEN THE BODY CAN'T KEEP UP
At the ambient temperature of 95 F, the body can no longer keep up with its internal heat generation levels and the inner core temperature begins to rise. The only mechanism to release body heat from the inner core is for up to 48 percent of the body's blood to be pumped to the skin to create perspiration.
This creates two problems. The first is blood loss to the organs, muscles and brain. The second problem is dehydration. When the brain, muscles and major organs are receiving half of the blood they normally receive, the heart must work much harder to try to deliver the same volume of blood to those organs to keep them nourished by beating up to 150 times a minute. When you factor in a thickening of the blood due to fluid loss (dehydration), you begin to understand why heart attacks are a major byproduct of heat stress.
 

  This is why I never could understand why we loaded our troops up with 130 pounds of gear and hot uniforms and sent them into the desert in Iraq when it was well over 100F. Seemed like asking for trouble. The other side was dressed in lightweight clothing.

 I just turned on our A/C last night. I always run it for 10 minutes and then turn it off to let the condensate trap fill up. If I don't do that it means a trip into the attic crawlspace to empty the overflow pan which has a safety switch on it.Hopefully I'll come home to a cool house tonight as it is supposed to get well into the 80s this weekend. I think you can overdo air conditioning though and become a wuss who can't handle real weather if you don't get out in it at all.

 I generally don't mind hot weather during the day but at night I have a tough time sleeping if the humidity is high and no air is moving. 76 with low humidity is ok. All about acclimatizing I suppose. When I lived in Georgia we never had A/C and the humidity was well over 90% and  90F. Sleeping could be more of a chore than a comfort. We had fans and that was all. If we walked into a cooled grocery store we felt like we had entered heaven.

 Women and men have different thermostats. I like cooler and my wife likes warmer.

Funny the study doesn't mention humidity. Excess humidity slows the bodies ability to dissipate heat. Heart attacks brought on by heat are especially apparent in people who have bad blood pressure or circulation to start with. The heat makes their bodies go into panic quicker than a healthy person.

If you are older drink plenty of water and  work in the cooler parts of the day,and not for very long at a time.

I keep cooler by avoiding toxic threads.

Toxic threads are fine if you traverse them correctly.

Here's the safe procedure.

You sure that's the correct hand gesture?

There isn't a correct one, you just have to keep it vague otherwise somebody will point out you've got it all wrong.

I learned that off McQ.

It was a powerful lesson.

If the drip pan is filling with water, it means the condensate line from the condenser unit in the attic is clogged. There should be no water in that drip pan at all.  I keep an eye on the condensate pipes when the units are running as I have 2 split units. as long as water is dripping from the pipe, all is fine in the attic. 

On one of my units a few years back I noticed no water dripping out. So a quick trip to the attic showed the pan with about one inch of water in it. The pan's drain line also happened to have some sort of issue with it so I had to fix the drain on the pan and then I had to unclog the condenser drain. Now, they are both working like they are supposed to. 

On the second part..... yeah.... my wife and I are the opposite ...she likes it cold and I prefer it a bit warmer. I work outside a lot and in attics and under houses so I'm usually in the heat quite a bit. Here in NC it's hot and humid. To me.... 80 degrees would be a cool welcome relief..... but I walk in and it's 70 in the house, because my wife stays inside a lot and to her 74 is warm..... 

I frost up when I come inside at the end of the day. It's almost like when, as a kid, I used to stick my head into the freezers at the supermarket and breathe in.... the hairs in your nose freeze up instantly..... I think Mooch  still does that from time to time....

  I should have explained myself here Guitarhacker. Thanks for the help though.

 In the winter months the condensate trap dries out from non use of the air conditioning. If the trap is empty when you start the air conditioner in the summer the air handler will pull pressure through that trap since it is on the suction side of the blower. The result is that the water that should go through the drain will be pulled across the primary drain pan and end up in the secondary emergency drain pan tripping the emergency off switch in order to save the ceiling from a flood. To stop this happening I run the air conditioning for a short time.... 10 to 15 minutes. Shutting it back off after this will let the water loaded evaporator coil fill the empty trap. When I re start the unit the trap has filled and I have saved myself a hot itchy trip into the attic to take the water out of the secondary pan and fill the trap. Anyone with an attic system should do this. If your drain is blocked you can blow it from the exit end and maybe also save yourself a stiff AC service call.... I was the guy who  collected that fee :)
