Every year, countless
wildfires take lives and leave people homeless. Before we can actually
be safe from wildfires, we need to better educate ourselves on the various
causes and safety measures. Awareness will help us establish wildfire
prevention in the future.
What causes
wildfires?
Wildfires
are a natural phenomenon of the environment – nature’s way
of eliminating dead vegetation. Although the weather plays an important
part, seventy-five percent of wildfires are caused by people being careless.
Many people might guess that smoking and lightning are the most common
causes of wildfires; however, both are in the minority. Most wildfires
are caused by people burning debris, vehicle exhaust, sparks from trains
and heavy equipment, camping, smoking, arson and lightning..
Causes of wildfires
will vary depending on where you live, the season, the climate, the vegetation,
the topography, and the weather. To better understand the causal factors
is a step towards prevention.
Fire-resistant
materials
Homeowners living in rural areas should consider using fire-resistant
materials in their homes. The roof is a home’s largest surface area
potentially exposed to airborne sparks called firebrands, which pose the
greatest threat. Should a wildfire near your home, the roof of your house
should be kept continuously wet to prevent firebrands from causing damage
or harm.
The most fire-resistant
roofing materials include metal, tile and fiberglass. Asphalt shingles
and tarpaper roofs also have some fire resistant properties; however,
because they are made of oil-based products, a significant level of heat
can cause them to ignite. As you can probably guess, wood offers the least
protection; a small spark can set fire to dry, sun-baked wooden shingles.
Although the roof
is the most likely target of a wildfire, walls and windows can also play
a determining role in the spread of fire. Walls should be built with fire-resistant
materials such as stone, brick or metal. Wood and vinyl offer the least
protection. Windows allow radiant heat to pass through them and can, at
times, set fire to curtains. Large windows break more easily than small
ones as they radiate more heat. Multi-pane windows give better protection
from radiant heat than single-pane ones.
Firefighters
Homeowners who live outside of major urban areas may be living in peaceful
seclusion, but are also at a disadvantage with regard to fires. Because
there are fewer firefighters in rural areas, country folk should be well-informed
on wildfire prevention, and on how to protect their homes from fire risks
and hazards. In order to rest assured, contact your local fire department
– they would much rather help you prevent a fire than have to rush
over to extinguish one.
In the event of an
emergency, firefighters need to get to your home quickly and safely. Clearly
mark the entrance to your property with a sign indicating the house number,
road name, and any other necessary details. It’s important to ensure
that the sign can be read from the main road; keep trees and bushes cut
back so the sign remains visible.
Other factors
of wildfires
Weather is the most important factor influencing the behavior of wildfires.
Topography (land features such as lakes, rivers, swamps, hills) also plays
a crucial role in how wildfires spread. For example, fires spread faster
uphill because of heat radiation and convection. The steepness or slope
of a hill also affects the speed of the spread: the greater the slope,
the faster the spread. Vegetation can act as fuel during a fire. Clear
any vegetation growing near your house, especially dry vegetation as it
would intensify and speed up a fire’s spread. Do not have trees
too close to your home in order to minimize fire hazards.
The essentials
Wildfire prevention has the same essential requisitions as all other fires:
be informed and prepared. Install smoke detectors or alarms, test them
monthly and replace the batteries regularly. Be sure to have functional
fire extinguishers on every floor of your home, especially in the kitchen
and garage. Know how to use a fire extinguisher.
Of course, the best
defense is a good offense. You and your family should know how to react
in the event of a fire emergency. Develop a fire escape plan and practice
it with your family regularly. The escape route should have at least two
ground-floor exits.
Prevent!
While nature causes many wildfires, the majority are caused by humans.
Wildfire prevention is of the utmost importance if we wish to save our
environment, our homes, and our lives. For more information on reducing
