2019 has seen a dramatic increase in
the impact and severity of wildfires worldwide. The last few months have seen wildfires
sweep across California, Brazil, Greece, Indonesia, Australia, the Congo Basin,
Siberia – causing loss of life, chaotic evacuations and massive disruption.
Environmental conditions linked to climate change are also making
wildfire seasons longer and more severe around the world.
Huge impact on air quality
Wildfires can cause temporary large increases in outdoor airborne
particles and substantial increases in gaseous air pollutants such as carbon
monoxide, nitrogen dioxide, formaldehyde, and acetaldehyde.
Large wildfires can increase air pollution over thousands of
square miles.
There are now various websites and apps that provide air quality
monitoring. However, these all pull their information from data sets from
government agencies, crowdsourced monitors and satellite imagery and do not
provide a real-time and location-specific status.
“They certainly don’t provide enough data, depending
on how many monitors there are locally. Wildfires, depending on the size, can
cause drastically varying smoke levels in a location, depending on how
close you are, wind direction and speed, and the size of the fire,” explains
Tim Turney, Global Marketing Manager at Casella, a leading manufacturer of air
monitoring equipment.
So while you may think that the information is reliable, the only
way you can know for sure the air quality in your area is to have an air
monitoring solution.
Who should take action to monitor air
quality directly?
Schools, hospitals, local communities,
office and industrial parks.
“Definitely locations where large numbers of people are congregated.
But at an individual level, especially those who are vulnerable should take
particular note of what is going on in their local area,” says Tim Turney.
“The particulate generated from wildfires is a general risk to public health, as it will drastically elevate particulate levels downwind of the fires. Just like general air pollution from sources such as traffic, elevated levels of pollution are associated with long-term health effects. In the short term, vulnerable people are particularly at risk, such as the elderly and the young, and people with existing health conditions such as asthma. Therefore, monitoring for particulate levels and knowing when to stay indoors, by having reliable information about the levels, would be an enormous benefit. We need to keep in mind that the visible smoke may have dissipated to a level where it is not visible in the air, but particulate levels will still be high. This is where precise monitoring equipment such as the Guardian 2 is needed,” adds Tim Turney.

What air monitoring solutions do
emergency services use?
Besides the general public, those fighting the fires and/or
cleaning up in their aftermath have other concerns. House fires inevitably
create a huge list of toxic chemicals, because of plastics found in many modern
houses for instance, and firefighters and anyone in the vicinity can be exposed
to toxic levels.
“We have seen a significant increase in the demand for personal air
sampling pumps like the Apex 2 to monitor in these situations,” says Tim
Turney.
How does it work?
Monitoring air quality is not as complex or difficult as it
appears, and the equipment will monitor air pollution levels in real time and
in the exact location being monitored. It requires one or several pieces of
equipment such as Casella’s
Guardian 2 or
Apex 2,
depending on the size of the area being monitored.
The Guardian 2 also monitors for wind speed and direction, which
is of paramount importance in the case of a wildfire. An environmental
monitor helps achieve early detection of air contaminants and
that can help reduce the emission exposure to surrounding communities. The small, lightweight solution is easy to transport, install and is
cost effective, and can send real-time alerts when air pollution levels become
cause for concern.
