I recently attended a conference at which someone asked me what I thought was the most important part of my job. I quickly responsed that the most critical function of a fire chief is to keep firefighters safe. Everything I do is related to firefighter safety, whether it is attending a budget meeting, developing operational guidelines, scheduling training, mentoring, pre-planning, or responding.

I am about to embark on a sensitive topic: obesity and weight loss. Quite often firefighters ask about their weight concerns, and express a desire to lose weight. However, there are firefighters who are in complete denial about their weight. In my opinion, they are walking the fine line between life and death.

Firefighter David Gillis never knows when a response to a call will trigger the symptoms of post-traumatic stress disorder (PTSD). But through a program called Strategic Resilience for First Responders, Gillis is able to manage the mental and physical reactions that used to stop him in his tracks.

The neigbouring fire department calls you about a multi-casualty collision to which it responded. Among the dead are well-known community members, some related to responders.

Making a conscious effort to build your personal resilience is one of the most important things you can do for yourself as a firefighter. Being a firefighter is physically and emotionally demanding. Having a tailored personal resilience program can produce positive results and help to maintain work-life balance.

Mental-health programs teach us that the effects of trauma can be cumulative. As a chief officer, do you know how much exposure your crews have had to traumatic incidents such as fatalities or calls involving children?

Not all critical incident stress management (CISM) programs are equal. Having had the privilege to work on four CISM teams, it is clear that certain practices and protocols enhance the program for both facilitators and participants. If your department is looking to adopt a CISM program, here are some considerations.

Dead children, severe mutilation, homicide, known victims, aircraft crashes, injured and dead firefighters: sadly, I don’t think my experiences of fire fighting are unusual. Who could deny this takes an emotional toll on us? Who would argue that as an organization, a profession, we don’t have an obligation to address the emotional cost?

Life is too short; we have all heard this cliché many times, but it seems that the older you get the more you hear and use it. So, if life is too short, what are you doing to make the most of it?

For many years, firefighters took pride in the soot that covered their bunker gear, helmets and gloves; it was a sign that they had been to a good job, and evidence that they had been on the front lines of fire attack. As fire prevention efforts paid off and the number of structure fires decreased, fewer firefighters engaged in fire attack; when they did, they were sure to leave all the evidence in place.

June 2016 - Fire Chief Colin Shewell and Deputy Chief Roree Payment are the only full-time members of Clearview Fire and Emergency Services in Ontario. The department heads were naturally nervous when they decided to introduce a mandatory annual physical-abilities test for all paid-on-call firefighters.

Much has been written about cancer and its relationship to the fire service. The bottom line is that if you are a firefighter you have a higher chance of getting cancer than a non-firefighter. Rather than argue about how many times more likely we are to get cancer, I would rather discuss some ways chief officers and firefighters can help reduce these odds.

Electrolyte deficiencies and dehydration are the most common preventable occupational hazards faced by firefighters. Firefighters, similar to high-level athletes, lose water rapidly during physical exertion. Water is the carrier of electrolytes, so dehydration leads to electrolyte depletion. Almost all firefighters have experienced an intense fire with searing, radiant heat, hours of physical activity in heavy bunker gear and quick changes in core body temperatures. The body depends on sweat to cool itself, so an extreme fire situation can quickly empty its water reserve.

There are a number of risk factors that affect depletion of water and minerals in a firefighter. Firefighters, wearing layers of non-breathable clothing to protect themselves, often deal with high temperatures inside a structure or outside on a hot summer day. Extreme sweating in these conditions depletes the body of all its water and good minerals.

Research conducted by the University of Cumbria in England, in collaboration with Cumbria Fire and Rescue Service, highlights how vital proper hydration is to a firefighter’s performance. The study identified that a high percentage of firefighters arrived to a training exercise or a real fire incident already significantly or severely dehydrated.

Electrolytes are minerals that are essential for the body to function. When water with electrolytes is consumed, the minerals are dissolved in the water and they enter the blood system. These minerals have ionic electrical charges that drive the function of every cell in the body. So imagine the importance minerals such as potassium, sodium, calcium and magnesium play in holding water in the body, making your cardiovascular system function and allowing energy production in muscle, brain and vital organs. Water and electrolytes are critical for peak performance, but are by far the most important health issue often overlooked. Dehydration, in extreme cases, can cause death.

 Potassium is probably the most important mineral in the body. Potassium helps maintain electrical activity in the brain and the heart. Potassium deficiency, for firefighters in extreme occupational situations, can be life threatening.  

The second most important and the second most abundant mineral in the body is phosphorus. Phosphorus is used for protein, fat and carbohydrate synthesis in the body; these key nutrients are integrated into DNA and cellular membranes. For firefighters, this mineral is mostly used in recovery after intense firefighting activity.

Sodium is known to regulate the level of water in the body. The more water you drink, the more sodium will be removed from your body via the kidneys. Sodium is used in transmitting important but subtle information from cell to cell in the body. Finding a good balance between sodium and water intake is critical.

Magnesium is responsible for more than 400 biochemical interactions in the body; about half the magnesium is found in critical organs such as the heart, nerves, muscles and the immune system. When firefighters experience muscle cramping during or after an intense fire, they should reach for large dosages of magnesium to reverse the effects. Depleted magnesium stores in the body prevent the muscles from physiologically performing. If a muscle does not slide properly, sudden movements can damage the tissue. A muscle pull is the most common fire-scene injury for firefighters.

There are many signs associated with electrolyte and water deficiency and imbalance. In the rush of life and especially fire fighting, we often overlook the simple act of rehydration. Examples of symptoms associated with water and electrolyte deficiencies include muscle spasms, restlessness, insomnia, dizziness, headaches, fever, heart activity, heart palpitations and blood pressure issues. If ignored and not treated, these symptoms become chronic and sometimes life threatening.

Finding electrolytes and water in whole, complete foods is a great way to increase minerals in the body. Vegetables are an excellent source of electrolytes, especially when combined in a soup. Consider adding kale, artichoke, spinach, parsley and Swiss chard into your diet. Another way to boost mineral intake is to use salts that contain more minerals, such as Himalayan, Celtic or sea salt. Fruits can also be a great source of minerals and water, including bananas, coconuts and avocados.

As a firefighter, make sure you are properly hydrated and balanced with electrolytes to maintain an optimum performing body.

May 2016 - There’s one in every station – the ticking-time-bomb firefighter whose demeanour slips Jekyll-and-Hyde-like between everyone’s best friend and look-at-him-sideways and he’ll snap.

In the past few months I have conducted many firefighter physical exams for a number of fire departments. As I was going through the medical assessments, I observed an interesting trend: a significant number of firefighters still smoke.

There is a sort of cliché that Americans and many Canadians say to returning military: “Thank you for your service.” Some soldiers appreciate it; many hate it because they figure that it’s easy to say but doesn’t begin to reflect an understanding of what they’ve been through.
