How a Hygrometer Works

Does your home often feel dry? Or too muggy? If you are experiencing chapped/dry skin, or difficulty breathing while in your home, you may need to get your humidity level checked out. Humidity levels that are not between the averages of 30- 50 percent can be potentially dangerous for your health. You can personally check your humidity level in your home by using a hygrometer.

A hygrometer is an appliance that is designed to calculate the amount of humidity in a room or building. While a hygrometer can’t actually prevent mold from growing, it can warn you to take any steps necessary before the problem occurs. Hygrometers can provide the accurate levels of relative humidity and absolute humidity. Relative humidity is the percentage of humid moisture in the air. Absolute humidity is the actual amount of moisture in the atmosphere.

What Makes a Hygrometer Work?

There are two commonly used types of hygrometers: Mechanical hygrometer and wet and dry bulb psychrometer.

Wet and Dry Bulb Psychrometer

This is the easiest way to measure humidity. This type of hygrometer is equipped with two mercury thermometers, where one has a wet bulb and the other has a dry bulb. Because of the evaporation of water on the wet bulb the temperature will drop and read a lower temperature than what is displayed on the dry bulb. The difference between the two temperature readings equal the amount of relative humidity in the atmosphere.

Mechanical Hygrometer

A mechanical hygrometer requires a little more effort to determining humidity levels in a room.

  • This tool was first created in 1783 by a physicist named Horace Benedict de Saussure.
  • Mechanical hygrometers work by using an organic material, typically a piece of hair where its behaviors can predict the amount of humidity in the air.
  • If you’ve ever noticed how human hair tends to frizz when there is a lot of moisture in the air or it is very hot outside, then it will be easy for you to understand how this tool works.

For example, the piece of hair is attached to a spring and needle instrument that exposes the hair to humidity. Based on the reaction of the hair, the humidity level can be classified. Although a wet and dry bulb is more accurate and easy to understand, a mechanical hygrometer is still as effective.

How to Reset Your Hygrometer

Should you need to ever reset your hygrometer, you can do so by using at-home methods:

  • In a room with normal, consistent temperature, place your hygrometer in a cup or container filled with salt water on a counter space. Leave it to sit for 10-12 hours.
  • After the allotted time, the hygrometer should read a standard relative humidity level of 75 percent.
  • This process should be performed at least once a year to ensure your hygrometer is always providing accurate results.

What makes it effective?

Hygrometers are the go-to source for measuring humidity. This tool can be used in laboratories, manufacturing sites and storage vicinities. Even meteorologists use hygrometers to report the most accurate amount of relative humidity in the community. Hygrometers are widely used because they come with hard-to-beat features. Many hygrometers are built with alarms that will alert you when the humidity level in your home is under that 30 percent or over the 50 percent average humidity level.

Hygrometers can serve as a great way to keep you, your family, home and belongings healthy. They can also come with humidistats, which control the operation of your humidifier or dehumidifier.

Carbon Monoxide Protection At Home & Work

Every year, according to the Centers for Disease Control and Prevention, hundreds of people in the U.S. die from carbon-monoxide (CO) poisoning—and the invisible, odorless gas sickens thousands more.

The numbers seem even more tragic when you consider that most of these deaths and illnesses are preventable. Here are tips from the Consumer Product Safety Commission and the Occupational Safety and Health Administration to help protect yourself and your loved ones at home and work.

At home

  1. Make sure you have CO alarms—and that they work. You should have a CO alarm on every level of your home and outside sleeping areas. Test them and replace batteries regularly, too. The alarms themselves should be replaced every five years or as recommended by the manufacturer.
  2. Get your chimney and furnace checked. A chimney or furnace that isn’t functioning properly can lead to CO buildup inside your home. Have a professional examination and/or service before you begin using them.
  3. Be careful with generators and grills. Neither should ever be used inside your home or in an enclosed space, such as a garage—even semi-enclosed spaces like porches can be risky, too. Keep generators at least 20 feet away from the house when in operation.

At work
In general, the same precautions for homes apply here, but there are a few additional considerations for the workplace, particularly one where gas-powered machinery is used:

  1. Be mindful of ventilation. Every year, workers are poisoned by CO while using fuel-burning equipment in areas that don’t have adequate ventilation.
  2. Try using different tools indoors. Consider electric tools or ones powered by compressed air, and if possible, avoid using forklifts, pressure washers and other gas-powered equipment. Ensure machinery and tools are maintained properly, too.
  3. Report unsafe conditions or issues. If you see something that might cause CO buildup, or you suspect CO poisoning in you or a co-worker, get people out of the area and report the problem to your employer immediately.

Whether you’re at home or work, always be on the lookout for symptoms of CO exposure: They include dizziness, drowsiness, headaches, and nausea. If you suspect an issue, leave the area as soon as possible and call 911—because when it comes to CO, it’s better to be safe than sorry.

Hail Storm Dangers

Hail doesn’t discriminate and rarely comes with an advanced warning – it can happen anywhere, at any time. Between 2000 and 2013, U.S. insurance companies paid out more than $54 billion in hail damage claims, with 70% paid between 2008 and 2013. In 2015 alone, the United States had more than 5,000 hailstorms. While most hail damage affects property and crops, unpredictable storm conditions can also put you in harm’s way. The following are three reasons why you should be wary of hail storms.

1. Hail can be as small as a pea (1/4 inch in diameter), as big a softball (4.5 inches in diameter), or even bigger in rare cases. The largest hailstone ever recorded in the U.S. fell in Vivian, Nebraska in July of 2010, measuring eight inches in diameter and weighing 1.9 pounds. Can weather forecasters predict the size of hail in advance? Sometimes. Hail forms when a strong storm’s updraft (upward-moving current of air) carries rain into freezing layers of the atmosphere, creating tiny hailstones. They get bigger when they run into super-cooled water droplets. If these updrafts are especially strong, they can hold the small hailstones aloft, allowing them to grow larger until eventually they become too heavy and fall to the ground. In other words, the stronger the storm, the larger the hail. Fortunately, baseball-sized and larger hail isn’t very common, on average just 24 people per year are reported injured by hail. But such injuries can be very dangerous and painful,  so it’s important to pay attention to your local forecast if you suspect storms are nearby.

2. No matter its size, hail still poses major risks. Small hail (half an inch in diameter) can reach speeds of 20 mph and usually comes down in larger quantities than large hail, creating a greater risk for damage. What is the typical scale of a hail storm? It varies considerably. Hail falls in paths known as “swaths,” or “streaks,” which can cover anywhere from a few acres to 100 miles wide and 10 miles long. Dense swaths of hail of any size can do serious damage to both people and property.

Unfortunately, there’s not much you can do to prevent major hail damage to your home and cars. But if you live in a hail-prone part of the United States, you can take a few steps to lessen the aftermath of the next major storm:

  • Keep your car parked in a garage if possible. If you don’t have access to a garage, cover it with heavy blankets for a little protection.
  • Consider impact-resistant shingles for your roof.
  • Install storm shutters on your windows and doors to protect them from shattering.

3. Any type of thunderstorm can produce hail, but “supercell” storms (severe, rotating thunderstorms) are responsible for most big hailstones. If you see large hail (the size of a quarter or larger) that could mean the storm has tornado activity as well. What signs point to a possible tornado? Large hail usually falls north of a tornado, but just because you see hail doesn’t mean there’s a funnel on the ground. If a storm suddenly drops hail, immediately take cover and listen to your weather radio for storm reports in your area.

If you’re inside, you should stay there until the storm completely passes:

  • Make sure everyone is safe and indoors.
  • Stay away from windows and doors.
  • Don’t go outside for any reason.

If you’re driving, try to get somewhere safe like a garage, gas station, or bridge that’s nearby:

  • Do not leave your car until it stops hailing.
  • Cover your eyes, and if you can, get on the floor or lie down on the seat with your back to the windows.
  • Protect small children with your body or heavy clothing.

If you get caught outside during a hailstorm and can’t get inside a structure, protect as much of your head and body as possible:

  • Avoid ditches and low areas that could suddenly flood.
  • Don’t seek shelter under a tree, as it can lose limbs and may attract lightning.

Most types of hail can pose significant risk to you and your property. But with a little upfront preparation and some common-sense safety measures, you can keep your home and family safe the next time this weather threat emerges.

Stranded on the Road

Few people like driving through a snow storm, and most heed warnings to stay off the roads when a storm is bearing down. But even the best-prepared and expert drivers can get stuck. If it happens to you, here are some important reminders:

Be prepared. While the best first step is prevention, some storms come on quickly. If you do get stranded, keeping a few essentials in your car can help keep you comfortable while you wait. Some useful items to keep on hand include an ice scraper and brush, drinking water, blankets, and high-energy, nonperishable food.

Stay inside. If possible, pull off the highway and turn your hazard lights on or tie something bright to your car’s antenna to signal that you need help. Then wait inside your car until help arrives to avoid exposure to frostbite and hypothermia.

Call 911. If you have a charged phone and reception, call for help and describe your location as best you can.

Clear the tailpipe. Make sure there’s no snow covering your tailpipe in order to prevent carbon monoxide buildup inside the car. Check the tailpipe periodically to ensure that fresh snow isn’t blocking it, always watching for oncoming traffic before exiting your vehicle.

Keep moving. Staying active inside your car will help you keep warm. Clap your hands and tap your toes to keep your circulation moving and prevent frostbite.

Drink up. Dehydration can make you more susceptible to the effects of cold. If there’s no drinking water inside your car, melt some snow inside a bag or other makeshift cup to stay hydrated.

Rev your engine. Provided you have enough gas in your tank, run the engine for about 10 minutes every hour to keep the car warm. Turn on interior lights when your engine is on so you can be seen inside your car.

Don’t overexert yourself. Cold weather puts your heart under added stress. If you’re not used to exercise, shoveling snow or pushing a car could put you at risk of a heart attack.

Today’s Homes Burn Faster

A fire in a modern home is a “perfect storm,” according to safety consulting and certification company UL (Underwriters Laboratories). Larger homes, more open layouts, new construction materials and other factors mean fires burn more quickly, leaving less time for occupants to escape — and for firefighters to stop the flames. How much less time? About 30 years ago, you had about 17 minutes to get out of the house once it caught fire. Today? Just three or four minutes.

A lot goes into creating that “perfect storm,” experts say. Here are some key factors:

  • Building materials. Particle board and other man-made materials, which are lighter and cheaper than natural wood, often are used to construct homes today. This leads to larger homes at a lower cost, but they also burn more quickly than solid wood, concrete or masonry.
  • More space — and more stuff. Fires can spread quickly in homes that are largely open, with high ceilings, etc. And homes that are bigger typically have more things in them — which means there’s more fuel for the fire.
  • Newer stuff. The old days of couches, carpets, etc., made from all-natural materials are long gone. That’s great news for durability and price, but it’s not great for limiting fires. Though many modern furnishings are excellent at resisting smoldering (such as if a cigarette is dropped), once they actually catch fire, they burn very quickly.

What can you do? Well, unless you’re having a house built or doing an extensive remodel, you can’t really change the materials used to construct your home. However, there are a few things you should do immediately to help keep you and your family safe, no matter where you live:

  • Make sure your smoke detectors are in working order.
  • Create an escape plan for you and your family.
  • Place fire extinguishers on each level of your home, as well as in the garage.

8 Ways To Improve Indoor Air

Air pollution isn’t limited to the outdoors. Moisture, odors, gases, dust and a host of other irritants can affect air quality indoors, too. Try these tactics to help freshen your home’s air so you and your family can breathe easy.

  1. Open windows.  Most heating and cooling systems recirculate inside air. When weather permits, give your system a break and let fresh air in. Open windows and place fans strategically to help direct fresh air through.
  2. Use exhaust fans.  Turn on the kitchen fan to vent cooking pollutants, and the bathroom fan to curb mold-promoting wetness and cleaning-product fumes. Leave it running for about 45 minutes.
  3. Do doormats.  They help prevent dirt and other outdoor pollutants from making it inside. Get two natural-fiber mats, one for inside and the other for outside your main entrance. Keep a shoe-free home, too.
  4. Test for mold & radon.  The naturally occurring gas is colorless and odorless. It’s also the second-leading cause of lung cancer, after smoking. DIY test kits, available online and at your local home improvement store, are inexpensive and easy to use. Mold can linger in a home without you even knowing it.  Having your home professionally tested could indicate whether or not you may have a mold problem.
  5. Don’t mask odors.  Scented candles and sprays can irritate lungs, too. Find the source of the smell, get rid of it, then ventilate well until it’s gone.
  6. Use a dehumidifier.  Stay under 50 percent humidity to keep mold growth at bay. Clean your dehumidifier regularly, too, so it doesn’t switch from humidity-reducing friend to mold-harboring foe.
  7. Vacuum regularly.  You’ll reduce the amount dust and other pollutants released when you walk around. Invest in a quality vacuum with a HEPA (high-efficiency particulate air) filter, especially good at trapping even tiny bits of dust and dirt.
  8. Take it outside.  Painting, sanding, gluing — anything that generates particles, gases or other pollutants. If outside isn’t an option, open a nearby window and add a fan blowing air out. Clean up after your project quickly and well.
