International SOS Daily Digest Addressed Wildfire Health Concerns

International SOS released the updated information below in it's Daily Digest: 
Canada: Advisory: Potential health risks from wildfires in Fort McMurray region

In Brief

Parts of northern Alberta are experiencing poor air quality following regional wildfires. The city of Fort McMurray has been evacuated and sections of the city have been damaged by fire. As of late May, the conditions improved in areas north of Fort McMurray and mandatory evacuation order was lifted in some areas. Polluted air can cause symptoms such as wheezing, coughing, shortness of breath, irritation of the eyes and nose and can also aggravate existing heart and lung disease.
Advice
  • Avoid travel to Fort McMurray while the mandatory evacuation order remains in place; members in the vicinity of Fort McMurray should adhere to all instructions issued by the authorities.
  • Continue to monitor the situation via the Municipality of Wood Buffalo website and the International SOS Travel Security Alert.
During periods of high air pollution, people in affected areas, especially the elderly, young children, and those with underlying heart or lung disease, are advised to:
  • follow the advice of local authorities and evacuate when instructed to do so
  • minimise time outdoors
  • reduce physical exertion
  • keep windows and doors closed
  • consider using an air cleaning device
  • use air conditioner in ‘recirculate' mode
  • consider using a respirator (N95 mask) while outdoors (consult your doctor for an individual recommendation)
  • consult your medical practitioner if you experience symptoms.
More Detail
The area surrounding Fort McMurray has been significantly affected by smoke from forest fires in the region. The Canadian Government's Air Quality Health Impact (AQHI) scale has exceeded the maximum 10 which equates to a "Very High Risk" of adverse health effects. The severity of the air pollution will vary, depending on weather conditions, and the level of air pollution is projected to remain elevated for extended periods until the fires are brought under control. For the current air quality measurements, see the Government of Canada updates for the Fort McMurray area and a near real time map of fires in the region is available from NASA.
What are the health concerns of air pollution?
Generally, polluted air causes minor, acute health problems such as eye and nasal irritation and cough. Other symptoms include headache, nausea and vomiting. The chemicals and particles in polluted air can cause breathing passages to become temporarily inflamed, decrease lung capacity and result in wheezing, coughing, shortness of breath and even pain upon deep inhalation. It can also exacerbate chronic heart disease and existing respiratory conditions, like asthma and emphysema. Certain people, for reasons as yet unknown, are particularly sensitive to ozone even without any underlying risk factors.
Some groups are especially vulnerable to problems caused by polluted air. These include older people, children, and anyone with underlying chronic health problems such as heart disease, emphysema, bronchitis or asthma. Long-term exposure to pollution can result in reduced lung function, particularly in children.

Canadian PM Trudeau Visits Ft. McMurray; What Health Concerns Await Returnees?

Canada's Prime Minister Justin Trudeau is visiting Fort McMurray today, working with local officials to have evacuate residents back in their homes sometime in the next two weeks. But fires continue to burn in the area, and many residents will return to little more than ash. 

The CDC notes that wildfire smoke, due to its mix of gas and tiny particles of organic matter can be especially irritating to lungs and eyes, and is know to worsen cardiac and respiratory diseases. Older individuals, individuals with chronic heart conditions, and those with asthma and other lung problems are most affected by wildfire smoke, but people of all ages and health statuses can be adversely affected. 

Paper dust masks, such as those available at hardware and home and garden stores, and even surgical masks are not designed to filter the small particles typical to wildfire smoke and will likely be ineffective in preventing smoke particle inhalation. 

Ash and smoke from burned homes and other man-made structures are usually even more hazardous than organic ash and smoke from wildfires. Ash and burned structure remains are generally not considered hazardous waste, however may still contain contaminants with serious risks, such as asbestos, industrial chemicals, flame-retardant chemicals, cancer causing arsenic, lead, and nickel, as well many other caustic and irritant substances. 

Adults should avoid direct contact with ash and residue. Children and pets should not be allowed in or around ash or smoke from burned structures, and little may be salvageable from such structures due to contamination
