Carbon Monoxide Poisoning

You can’t see it, you can’t smell it, but you can prevent it

An odorless, tasteless, colorless gas, carbon monoxide (CO) is a potentially deadly danger that may be in your home right now.

A byproduct of burning fossil fuels, CO can quickly build up in poorly ventilated spaces. Common sources of CO in the home include:

  • Furnaces and gas heaters

  • Kerosene heaters

  • Fireplaces and wood stoves

  • Gas stoves and ovens

  • Portable generators

With the increased use of heating sources in winter and the sealing of doors and windows to keep out winter’s chill, the risk of increased CO levels in the home increases.

When breathed in by people or animals, CO builds up in the blood replacing oxygen in red blood cells. This can lead to serious tissue damage and, as noted, death.

Symptoms of CO poisoning vary based on the level and length of exposure.

Mild symptoms are commonly mistaken for the flu and include:

  • Headache

  • Fatigue

  • Shortness of breath

  • Nausea

  • Dizziness

  • Chest pain

High-level exposure can cause:

  • Mental confusion

  • Vomiting

  • Loss of coordination

  • Loss of consciousness

  • Death

While CO is undetectable to humans, CO detectors can alert you to dangerous levels.

Available online and at most hardware stores, detectors range from $15 to $50 and last up to 10 years.

The International Association of Fire Chiefs recommends installing at least one carbon monoxide detector on every floor of your home, including the basement. Detectors should be positioned within 10 feet of each bedroom and near or over any attached garage. Much like a smoke alarm, a CO detector will emit a loud noise when the gas is detected. Never ignore a CO alarm or attempt to find the source.

If you hear the alarm or even just suspect poisoning:

  • Immediately move outside to fresh air

  • Call the gas company, fire department or 9-1-1

  • Make sure every person and/or pet in your home is accounted for

  • Do not re-enter the home until emergency responders tell you it’s safe to do so

Be sure to test or change the batteries in your CO detector every six months. 

Other steps you can take to prevent CO poisoning include:

  • Have your heating system, water heater, and any other gas, oil, or coal-burning appliances serviced by a qualified technician every year.

  • Keep vents and flues free of debris

  • Never leave the engine running in a vehicle parked in an attached garage or carport

  • Never run a gasoline-powered engine (motor vehicle, generator, pressure washer) less than 20 feet from an open window, door, or vent

  • Never use a charcoal grill, hibachi, lantern, or portable camping stove inside a home, tent, or camper

  • Never run a generator, pressure washer, or any gasoline-powered engine inside an enclosed structure or basement, even if the doors or windows are open

 

CO poisoning is entirely preventable.  Visit the Centers for Disease Control and Prevention’s CO Poisoning webpage to learn more.

Home Office How To

Did you know that many sources of chronic pain start in a poorly arranged office? Carpal tunnel, pinched nerves, overuse injuries can often be traced to chairs being positioned improperly or important tools being positioned outside easy reach. While reaching or straining once or twice wouldn't hurt us at all, doing so repeatedly day after day can cause painful and lasting injuries.

As an occupational health physician at Southwestern Vermont Medical Center, one of my responsibilities is to help employees of SVMC and other companies who have workplace injuries and recommend the adjustments they should make.

During a spike in work-from-home arrangements, I have heard about friends’ and family members' work-from-home set-ups. Some are working from laptops on their couches. Others are set up at kitchen tables. We know that their cats walk across their keyboards and their kids interrupt. Especially since Governor Scott has just indicated that remote workers will likely be the last to return to the traditional workplace, it's time to get our home office arrangements figured out.

That's why I would like to share the important details you need to arrange a healthful workspace and encourage all to invest the time (and sometimes a little bit of money) needed to implement them. Learning these points is key to avoiding injuries, as continued work-from-home policies, where feasible, will help maintain appropriate distancing needed to decrease the spread of COVID-19.

An adjustable chair is the first and most important component of an office set-up. Office chairs include crucial lumbar support and encourage good posture. When your forearms are resting on your desk or table, adjust the chair height up or down until your arms form a right angle. This is an important step in avoiding wrist pain and carpal tunnel, two of the most common office injuries. If, when your arms are in the correct position, your feet are not touching the floor, employ a footstool.

Position your monitor an arm’s length away. (If you can't see the screen from this distance, better go get an eye exam!) And raise the screen so that the top of the screen is eye level. This, too, will encourage good posture.

If you use two monitors, positioning them properly depends on how you use them. If you use them equally, the dividing line between them should be right in front of you. If you use one primarily and the other secondarily, position the more dominant screen directly in front of you. If you use a laptop, consider investing in a riser and an additional keyboard needed to raise the screen to eye level.

Put all of your other tools, including your mouse and phone, within easy reach. If you use the phone a lot, consider investing in a headset.

The only other recommendation I make is to stretch every 15 – 20 minutes. A list of helpful office-oriented stretches is available here. And every hour, be sure to get up and take a short walk or standing stretch.

If you follow these recommendations at home, you will be much more comfortable and are likely to be more productive, too, all while maintaining the social distance we need to keep COVID-19 infections low throughout this next phase of the pandemic. Most importantly, you will save yourself the pain and discomfort of office injury no matter where you're working.
