Snowstorms and power outages present elevated risk for carbon monoxide poisoning

08.04.2014

More public safety education needed to decrease unintentional poisoning during and after heavy storms, according to new data published in the American Journal of Preventive Medicine

While preventable, carbon monoxide poisoning is a serious and sometimes fatal condition. Large weather events, such as snowstorms and heavy storms that cause power outages, can lead to an increase in the number of reported carbon monoxide exposures.

Researchers from Hartford Hospital in Hartford, Connecticut explored the link between these major storms and the rise in carbon monoxide exposure cases. They found that portable generators were the most common source of carbon monoxide exposure after storms which resulted in power losses; car exhaust was the most frequent source of exposure after heavy snowstorms.

Their findings are published in the May issue of The American Journal of Preventive Medicine.

In 2011, 12,136 unintentional exposures were reported to U.S. Poison Control Centers. Carbon monoxide is an odorless, colorless, and tasteless gas that can build up to dangerous levels in unventilated areas. Symptoms of carbon monoxide poisoning include headaches, nausea, and dizziness.

If left untreated, carbon monoxide exposure can lead to serious illness or even death. During and after severe winter weather, people are at an increased risk for exposure to carbon monoxide because of the use of alternative heat sources inside their homes and heating vents blocked by snow.

In this new study, investigators looked at data reported to the Connecticut Poison Control Center after two storms: a 2011 winter storm that resulted in widespread power loss and a large snowstorm in 2013. A total of 172 patient cases were identified after the power loss storm, while 34 cases were identified following the snowstorm.

Researchers found that most carbon monoxide exposures occurred within the first day of a snowstorm, and on the second and third days of a power loss storm. "These results indicate that the staffing patterns and call schedules of the medical providers involved in the treatment of carbon monoxide-poisoned patients may need to be adjusted accordingly, based on the type of storm expected," says lead investigator Kelly Johnson-Arbor, MD, Department of Emergency Medicine, Hartford Hospital.

During a power loss storm, the most common sources of carbon monoxide exposure are the indoor use of gas-powered generators, propane heaters and lanterns, and charcoal grills. "Adequate ventilation is a key component of carbon monoxide poisoning prevention," explains Dr. Johnson-Arbor. "Following multiple reports of carbon monoxide exposures and fatalities after power loss storms, there has been an increase in public health education regarding the importance of avoiding indoor use of generators and charcoal grills during a storm's aftermath."

Investigators discovered that snowstorms present a different set of dangers from carbon monoxide exposure. During and following a heavy snow, people are likely to be exposed to carbon monoxide in their vehicles as well as their homes. In dwellings, large snowdrifts can block heating vents, while vehicle tailpipes can become clogged with snow that causes carbon monoxide to leak back into the car.

"Lethal concentrations of carbon monoxide can form in the passenger compartment of a snow-obstructed vehicle, even when the vehicle's windows are opened 6 inches," acknowledges co-investigator Dadong Li, PhD, Department of Research Administration, Hartford Hospital. "It is therefore important to counsel the public to examine their vehicles after snowstorms to ensure that the exhaust area is cleared of snow, prior to starting the engine. In addition, people should be advised to avoid sitting in running automobiles during and after snowstorms, unless the exhaust area has been completely cleared of snow, regardless of whether the windows are opened."

Greater awareness of the dangers of carbon monoxide exposure has prompted more homeowners to install carbon monoxide detectors, however, they are not required nationwide. "Increased reports of carbon monoxide poisoning can occur after both snowstorms and power loss storms," adds Dr. Johnson-Arbor. "Enhanced public education or local policy actions concerning the use of carbon monoxide detectors, particularly in the aftermath of storms, may be particularly beneficial in states where the use of these devices is not mandated by law."

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
