Cold Weather Safety Refresher

Winter is in full force across many parts of the world.  The east coast of the United States is currently feeling the wrath of a Bomb Cyclone.  With the call for emergency responders in those areas most likely increasing during the storm, it is never a bad time to review cold weather safety tips.

Environmental cold can affect any worker exposed to cold air temperatures and puts workers at risk of cold stress. As wind speed increases, it causes the cold air temperature to feel even colder, increasing the risk of cold stress to exposed workers, especially those working outdoors.  In regions that are not used to winter weather, near freezing temperatures are considered factors for “cold stress.”

Types of Cold Stress

Immersion/Trench Foot

Trench foot is a non-freezing injury of the feet caused by prolonged exposure to wet and cold conditions. It can occur in temperatures as high as 60°F if feet are constantly wet. Injury occurs because wet feet lose heat 25-times faster than dry feet.

What are they symptoms of trench foot?
Reddening skin, tingling, pain, swelling, leg cramps, numbness, and blisters.

Frostbite

Frostbite is caused by the freezing of the skin and tissues. Frostbite can cause permanent damage to the body, and in severe cases can lead to amputation. The risk of frostbite is increased in people with reduced blood circulation and among people who are not dressed properly for extremely cold temperatures.

What are the symptoms of frostbite?
Reddened skin develops gray/white patches in the fingers, toes, nose, or ear lobes; tingling, aching, a loss of feeling, firm/hard, and blisters may occur in the affected areas.

Hypothermia

Hypothermia occurs when the normal body temperature (98.6°F) drops to less than 95°F. Exposure to cold temperatures causes the body to lose heat faster than it can be produced. Prolonged exposure to cold will eventually use up the body’s stored energy. The result is hypothermia, or abnormally low body temperature. Hypothermia is most likely at very cold temperatures, but it can occur even at cool temperatures (above 40°F) if a person becomes chilled from rain, sweat, or immersion in cold water.

What are the symptoms of hypothermia?
An important mild symptom of hypothermia is uncontrollable shivering, which should not be ignored. Although shivering indicates that the body is losing heat, it also helps the body to rewarm itself. Moderate to severe symptoms of hypothermia are loss of coordination, confusion, slurred speech, heart rate/breathing slow, unconsciousness and possibly death. Body temperature that is too low affects the brain, making the victim unable to think clearly or move well. This makes hypothermia particularly dangerous because a person may not know what is happening and won’t be able to do anything about it.

Cold Weather Research

In case you are wondering if anyone is researching the human performance of firefighters in cold weather environments.  The answer would be yes. Some of the PhD student’s at the University of Ontario Institute of Technology (UOIT) are researching what we go thru.  You can find more here.

Cold Weather Rehab

Rehab is an important part of any fire service operation.  However, the cold weather makes rehab extremely important to protect firefighters and get them back in service as quickly as possible. The International Association of Fire Fighters has a great Rehab Presentation that you can download.

Mike Smith, Absolute Rescue's Editor in Chief, is a veteran of the fire/rescue service in Michigan, who also works in the automotive industry as a designer. Have an idea of suggestion for the site? Contact Mike here

HydroFusion Ram

HydraFusion Struts used as ram for a dash roll?

HydraFusion Strut Ram

The HydraFusion Struts were a game changer when PARATECH released the lifting/stabilizing device a few years back at FDIC. Rescuers can lift up to 10 U.S. Tons (9 metric tons) and to stabilize up to 20,000 lbs. with the tool. However, PARATECH’s HydraFusion Struts are not limited to just those two functions. The HydraFusion Struts can move metal!

I first ran across pictures of HydraFusion Struts used as ram from pictures that Brock Archer (Advanced Extrication) and Randy Schmitz ( Founder/Owner of Schmitz Mittz). Last weekend at Crunchtime Extrication, Paratech had one of their trailers at the training event and I had the chance to try a dash roll with a HydraFusion Strut. Take a look at the video below.

A few quick points:

  • You can put the HydraFusion Strut in place to reduce any dash movement during reliefs cuts.
  • HydraFusion Strut are portable and can be moved quickly to a vehicle hundreds of feet of the roadway.
  • Depending on the length of the HydraFusion Strut used, strut extensions can be used to optimize dash movement.
  • Using a HydraFusion Strut as a ram is an option, not always the option.
Below  are a few pictures from the Advanced Heavy Rescue Symposium in Calgary, Alberta, that show HydraFusion Struts used a ram during bus extrication to displace a roof.

Hunter/Tree Climber Rescue

Hunting season is right around the corner in most parts of the United States. Have you trained on rescuing a stranded hunter hanging in their harness after a fall?

Tree Climber Rescue

Checkout the two videos below with some great game plans and tips on rescuing someone out of a tree or hanging in a harness after falling out of a hunting blind.

Harness Induced Pathology is a silent killer in High Angle Rope Rescue, it can also be known as Harness hanging syndrome, Suspension Trauma, Suspension Induced Shock, and Etc.

Skeletal-muscle pump

Did you know that your muscle help pump the blood thru your body? The skeletal-muscle pump is a collection of skeletal muscles that aid the heart in the circulation of blood. It is especially important in increasing venous return to the heart, but may also play a role in arterial blood flow.

Reference material:

Below is a PowerPoint on the effects of falling.
