- Protect Yourself From The Heat. As of tis writing, Arizona has seed it’s 27th day in a row of temperatures in excess to 110˚. We’ve also hit 119˚ four times this month.
What is the protective answer to all of this heat?
For those that can, stay inside in air conditioning. Cary a water bottle and refill/drink it down . The morning low in Phoenix today was 102˚ Tough to stay cool with temperatures like this but ever so important.
For those oof you who work outside, plan to get into some shade after every 15 minutes of work in the sun. Drink cold water for 30 minutes before returning to your work. Be sure you wear protective clothing that provides cooling. OSHA
In the evening after you have returned from work, go easy on your consumption of alcohol and caffinated beverages. At a time when you need hydration, these beverages will de-hydrate your system.
At least 18 people have died from heat related stress while enough 69 more deaths are under . Souce Maricopa County
Bodily water loss when you get hot….Water composes up to 60% of the human adult body,
according to the U.S. Geological Survey.
When an adult participates in physical activities or
exercises outdoors in high temperatures, they can lose anywhere between a half liter (17 ounces) to two liters of water every hour. If a person doesn’t hydrate adequately, his or her health could be hurt.
How much water should we consume daily. This display found in the Glendale Public library demonstrates this need quite well.
The display show 250 gallons of water consumed each day.
250 gallons a day seems like a lot when we are supposed to be curbing our water appetite. So try one of more of these:
Water your vegetable garden with a soaker hose so that the water goes directly to the plants. Any veteran gardener will tell you to water the base, not the leaves— the water will act like a magnifying glass and burn holes in the leaves.
Water your summer grass half of what it is used to. It may turn little brown but should come back in the fall when your reuse your normal schedule. OR convert your summer grass to a Xeriscape. Once complete, you’ll never have to water the lawn again.
Brush the dust from your car with a microfiber brush. If you think you absolutely have to wash it, take it to a car wash where your car emerges looking good and the the water used to wash will be recycled many times before being disposed.
Two species you may want to include in your water schedule are birds and bees.
Birds need water on a daily basis but, you need to change it daily to prevent mosquitoes from laying their eggs in the water.
Bees are dying in record numbers due to a lack of water. Bees are important as they are responsible for more than one-third of the food produced.
One has only to set out a shallow pan of water in a shady place and the bees
will come in and drink. Bees can’t swim! They must be able to stand where it’s dry and drink. Good systems include shallow bird baths or pot bottoms filled with water and pebbles or corks. These allow the bees to stand and drink; they’ll generally dry out too quickly for mosquitoes to be an issue Not to worry, they want water, they don’t want to sting you. But just to be safe, DO NOT touch a banana wile your placing the water out for them. Banana oil is the phermone bees respond to when “going to war”.
2. Keeping Your Bar-B-Que Propane Cool Pays Big Dividends. We all saw the major fire at Bill’s Propane in Phoenix tis past week and there are lessons to be learned from this.
You’ll want to keep the tank in a shaded area so that it’s not in direct sunlight for long periods of time— ut not in your garage or in the house. This should keep the tank at a safe temperature, note exceeding 120 °F (49 °C).
Central Arizona was very close to the explosive number of 120˚ with nine days reaching 119˚daytime high temperature
.
If your propane tanks are left in the sun and allowed to reach 120˚, one could experience a BLEVE situation we saw at Bill’s. BLEVE fires cannot be extinguished with water. All water can do is cool down the tank after it is too late.
Water flow rate to cool the tank is based on 5 ( √capacity (USgal) ) = USgal/min needed to cool tank metal. Source: https://cameochemicals.noaa.gov/erg_guides/bleve_safety.pdf
A BLEVE explosion and consequential fire stands for “boiling liquid
expanding vapor explosion”. The temperature of the burning propane is 3,560˚ F. Fire men will try to cool the burning tank while also fighting the flames that may be ravaging your home.
As millions bake under a relentless heat wave in the South and Southwest US – and as temperatures soar around the Northern Hemisphere – NASA scientists warned Thursday that we haven’t even seen the worst of El Niño and next year will likely be even warmer for the planet.
Climate change, caused by burning fossil fuels, is unequivocally warming the Earth’s temperature, NASA scientists said.
And El Niño, the natural climate pattern in the tropical Pacific that brings warmer-than-average sea-surface temperatures and influences weather, has only just started in recent months and therefore is not having a huge impact yet on the extreme heat people around the globe are experiencing this summer, said Gavin Schmidt, a climatologist and director of the NASA Goddard Institute for Space Studies.
