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: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
