The average body temperature is 98.6 degrees Fahrenheit. At an internal temperature of 95 degrees, humans can experience hypothermia, shivering and pale skin. At 86 degrees, they become unconscious and, at 77 degrees, cardiac arrest can occur. Most people cannot survive if their core temperature drops to 75 degrees.

At 80 degrees, there’s a good chance the humidity level in your home will be very high. This is not only uncomfortable but inefficient. When you turn your air conditioning back on, it’s going to have to work not only to reach your ideal temperature again but also to regulate the humidity level.

Some areas of the United States won’t get below 80 degrees some nights this week, resulting in a dangerous combination. Without air-conditioning, these hot temperatures can put a strain on the body that can result in heat exhaustion or even death.

If your thermostat is set at 80+ degrees, then the humidity inside of your home can easily get up above 70%. That’s much higher than the recommended ideal indoor humidity of 30-50%. Having indoor humidity above 50% can cause serious issues for your health and your home.

In the range of 90˚ and 105˚F (32˚ and 40˚C), you can experience heat cramps and exhaustion. Between 105˚ and 130˚F (40˚ and 54˚C), heat exhaustion is more likely. You should limit your activities at this range. An environmental temperature over 130˚F (54˚C) often leads to heatstroke.

Generally, a person can survive in 41-degree F (5-degree C) water for 10, 15 or 20 minutes before the muscles get weak, you lose coordination and strength, which happens because the blood moves away from the extremities and toward the center, or core, of the body.

140 °F

This plastic’s melting point is 170 degrees Celsius (338 degrees Fahrenheit).

According to Machinist Materials, polyethylene terephthalate — PET, or recyclable 1 — has a melting point of 255 degrees Celsius (491 degrees Fahrenheit). This plastic’s melting point is 170 degrees Celsius (338 degrees Fahrenheit).

When plastic is burned, it releases dangerous chemicals such as hydrochloric acid, sulfur dioxide, dioxins, furans and heavy metals, as well as particulates. These emissions are known to cause respiratory ailments and stress human immune systems, and they’re potentially carcinogenic.

Most plastic won’t melt in boiling water. Boiling water is at 100° centigrade which isn’t hot enough to melt plastic. Also there are various sorts of plastics like polyethylene (PE), polypropylene (PE), polyvinylchloride and much more, which are not gonna melt at 100° centigrade.

Polypropylene plastic can withstand high temperatures without melting.

Plastic Materials and Hot Liquids This can get worse with using warm liquids e.g. hot water in a plastic bottle. In fact, the rate of leaching plastics from its base material can increase by up to 55 % on using the liquid at high temperature like any beverage like coffee.

Yes, boiling water in plastic will introduce toxic chemicals into the water. But these same toxic chemicals are also introduced into the water at room temperature, just at a much slower rate, and no one, including the FDA, is up in arms about it as it just isn’t a concern.

While the melting points of different types of plastic vary widely, most of them are comfortably above the maximum temperature of liquid water under normal conditions, or 100 degrees Celsius (212 degrees Fahrenheit).

Researchers from the University of Florida found that when heated, plastic water bottles, which are made from polyethylene terephthalate, release the chemicals antimony and bisphenol A, commonly called BPA. …

Will boiling water melt a 5 gallon bucket? It won’t melt, though – even if the temperature of the water was at boiling point.

Polyethylene, polypropylene, and most common use plastics have a maximum long term temperature limit of 180F/82C. Putting boiling water in such a container won’t necessarily trash it but it will likely deform it. I boil in one of those PP buckets with no issues.

Boiling water doesn’t stay boiling very long once off the heat. You can’t heat the bucket itself enough to be that effective because its plastic and can melt, plus plastic is a lousy conductor.

HDPE or High Density Poly Ethelene plastic has an amazing temperature range, and is considered safe for short periods up to 248°F (120°C) or for long periods up to 230°F (110°C.) Since boiling water never gets above 100°C, this means that anything boiling and below is safe for a food grade bucket.
