Facing Electrical Issues

by Brad Banz

As firefighters, we respond to a wide variety of scenarios involving electrical hazards. Immediately, downed lines calls come to mind to most responders because of the obvious hazards they pose. In this article, I would like to discuss other types of incidents in which electrical hazards could be encountered and address our response as first responders.

Since I started the conversation by bringing up the topic of downed electrical lines, what should you do if you encounter such a situation? As in many other emergency situations, your job is to secure the area and keep people out. Electrical lines can carry many thousands of volts of electricity, with cross-country transmission lines carrying up to 345,000 volts. What does that mean to you? That means that you don't have to be in contact with the line for an electrical path to be established. Electricity from energized high voltage lines can jump several meters to things such as ladders if they are establishing a path to ground. The area around an energized downed line can also form a ground gradient, an area which is energized, and which will still be a shocking hazard.  That's why it's important to secure the area in between poles and keep all ladders a minimum of 3 meters away from energized lines. Treat all lines as energized. Also have the contact number available for your local electrical utility so they can be notified of the situation. If electrical lines are downed across vehicles, have the passengers jump to become free from the vehicle if they can do so. If they cannot, then make them stay in the vehicle until the electrical lines have been shut off by the electrical utility. 

Structure fires are another common instance when electricity can be an issue. While electrical service may not always be involved in the fire, regardless of cause, it's a good idea to secure electrical power to ensure that it doesn't become a hazard. Electrical power can usually be secured by turning it off at a circuit breaker if safe to do so. If electrical service is a major issue, the electrical utility must be notified so they can secure power outside the structure. The utility company should also be notified in areas such as informal settlements where illegal wiring arrangements are involved. The illegal wiring can be dangerous, especially with the iron sheet construction of many of these homes. Finally, one last consideration is hidden fire. If you have an electrical fire, or suspected electrical in wiring, open the wall up. 

Many machines, especially in industrial settings, use lots of electrical power. Many times, an electrical fire or smoldering electrical fire can be controlled by simply securing electrical power to the machine. Even if the machine has any fire involvement at all not involving the electrical systems, it's still good to secure power. If power cannot be secured, a powder extinguisher suitable for electrical fires should be used. One set of machines in which powder should not be used on are computers or other types of electronics. Many computer centers have their own halon extinguishing systems. CO2 extinguishers are the preferred agent for use on computers and electronics. 

While there are other electrical issues that you as a first responder may run across during your career, I tried to come up with the ones that you would be most likely to come across. I hope that everyone has gained something from this article. As always, stay safe out there.

The First Five Minutes

The First Five Minutes

by Mark van der Feyst

Every day in North America, fire departments are responding to structure fires that involve residential buildings. The bulk of the workload for the fire department will be the residential home as statistics show that every 86 seconds a fire department is responding to a residential fire. Once a fire department arrives on scene, they need to act quickly as the number one priority on the fire scene is life safety. This involves the occupants inside the residential building as well as the responding personnel. In 2014, there were 2,860 civilian fire deaths attributed to a structure fire.

The time a fire department’s first arriving officer and crew have to affectively size up situation and decide on what action to take in order to address the life safety priority is less than 2 minutes. Within that timeframe, many factors need to be considered, evaluated, processed and then decided upon based upon priorities. The first five minutes are crucial to any fire ground operation and sets the tone for the remainder of the call – it will either set the tone for a successful outcome or it will set the tone for a not so favourable outcome.

Studies have shown that fire grows at a rate that doubles in size every minute. Modern fuel loads and heat release rates add to the fire’s intensity. Every minute that we are indecisive on scene is another minute of rapid-fire growth. By using information gathered during pre-planning and from Dispatch updates, coupled with situational awareness and a strong size-up, the Incident Commander should be able to formulate tactical decisions that have positive influence on truck placement and task assignments taking into consideration manpower issues that face many smaller departments.

The First Five Minutes starts with how to correctly size-up an incident scene, and then how to get the information clearly and concisely to incoming units and Dispatch. As we all know, size up begins when the call comes in and ends when all are back at the station. How can we prepare ourselves ahead of time so that our size up will be streamlined and efficient when arriving? We can do this by sizing up our response districts during our down time or when we are driving around in our response areas. By observing the present clues that are in front of us on a daily basis, we can build a data bank within our minds of what we know exists within our boundaries.

One such area is knowing your response district and the types of residential buildings that comprise it. Knowing the common construction types, the common layouts, the average age of the homes and so on will help with creating different rescue profiles. By having these different profiles, the firefighter and company officer can gauge ahead of time what exactly they are dealing with and when the call comes in, they will have a better understanding of where they are going to and what they are getting into.

Another factor that can be added into the equation of knowing the area is with the demographics. Knowing who in terms of average age, in terms of type of population such as seniors or retirement type of people or maybe students will help with creating a rescue profile. This can be accomplished by searching for this information from local government or from just observing the response district.

Other aspects of the size up is with knowing common locations of where fire victims are found within the residential structure. They are usually found in exit areas such as windows, doors, top of stairs, bottom of stairs, middle of stairs, and in the hallways, at the fire location or in their beds depending upon the time of day. Knowing these common locations helps with the effective rescue and where to begin the search or which tactic to use.

The fire apparatus is another area that can be addressed for the first five minutes. One focal point is with the equipment options available to the membership. This involves setting up the apparatus for quick and easy access of required hand tools for any rescue operation. This involves utilizing compartment space effectively and placing certain tools on the right side of the apparatus.

Along with this is the aspect of combat ready tools. This is where the fire department can have certain tool combinations pre-made or pre-arranged and then placed in a spot on the apparatus that will be sensible and quickly grabbed. Such examples may be the hailgan and the axe, the haligan and the roof hook, the haligan and the maul, or the hailgan and the water can. There are many different tool variations that can be pre-arranged ahead of time.

Having pre-arranged seating assignments is also a good idea to quicken the rescue operation. This is where no matter who sits in what certain seat in the back or the front of the apparatus, they have a specified job function that is standard. This cuts down the time and decision making ability on who will do what – instead allowing firefighters to react based upon their assigned function.

One last area that can be looked at is our tactical options. There are many tactical options that are available for any one fire department to use – it is just a matter of using the right one for the right situation and being efficient with it. Tactics starts with training and becoming familiar with how they are beneficial, the reasons why they are different from each other and how they can be incorporated into the department’s operational capabilities.

Tactical options include things such as VES or VEIS, PPA, tactical ventilation, transitional attack, offensive attack, defensive attack, fast attack, blitz attacks, all hands rescue and so on. Tactics are a great tool for the firefighter and enable them to be effective on the fire ground – but only work when they are trained on time and time again. The place to use a tactic for the first time is not on the fire ground, it is to be used for the first time on the training ground.

By focusing upon these areas and others such as communications, the culture of the department, rescue plans and SOG’s and SOP’s, the fire department can be effective within the first five minutes.

Importance of Active and Passive Recovery for Firefighters

Importance of Active & Passive Recovery for Firefighters

by Nick Higgins

Firefighters are athletes. Taking care of ourselves means not just getting evaluated by our primary care or department physician but truly embracing a healthy lifestyle. Being able understand your body and prepare your body is equally, if not more, important to ensure our personal protective equipment is in check, self-contained breathing apparatus bottles are topped off, and the apparatus is in working order. The rigors and demands of the job place a toll on our physical and mental well-being, and it is vital we prepare our body and mind for the work potentially ahead of us, not just for one shift or call but for an entire career.

Active Recovery

Active recovery is beneficial to the body and may help us recover faster after difficult workouts or strenuous activity. I recommend that this type of recovery be on shift day or the day before or after to allow the body to recuperate from any physical activity performed on off days and to provide your body with some type of active, low-intensity recovery during shift so your body does not go into complete relaxation mode while on call. Limit active recovery exertion to no more than 75% of your typical workout level. The 75% level is just enough to keep the muscles warm and not enough to induce muscle fatigue.

Before we outline a few methods to perform active recovery, here are some of the benefits it provides.

• Reduction of lactic acid buildup in muscles.

• Elimination of toxins.

• Helps keep muscles flexible.

• Reduction of soreness.

• Increase in blood flow.

• Helps keep an exercise routine.

• Release of endorphins usually associated with regular exercise.

Here are a few methods of active recovery that are simple, yet highly effective:

• Walking

• Swimming

• Cycling

• Stretching

Passive Recovery

Passive recovery is a type of recovery that entails resting for considerable periods of time after strenuous activity. Unlike active recovery, with this type of recovery, your body is allowed total undisturbed rest to repair muscle damage and recuperate.

Proper passive recuperation is necessary for firefighters who are sick, are injured, or need physical and mental relaxation. For firefighters, rest is highly important and needed to perform at an optimal level. Rest has physiological and psychological benefits.

A healthy and optimal life is all about finding the right balance. From a 24-hour shift to 48 hours off in most cases, it is critical to take a day in between every now and then to relax and balance out the body.

By allowing the body to rest and avoid weariness of the muscles, it is allowing the body’s glycogen stores to refill, therefore attributing to the enhancement in muscle recovery. While exercise depletes your body’s energy stores or muscle glycogen, leading to muscular tissue breakdown, adequate rest helps your body correct this problem by restoring muscle glycogen, balancing blood flow, and rebuilding damaged tissue.

Here are a few methods of passive recovery that are simple, yet highly effective:

• Sleep

• Rest

• Hydration

• Massage Therapy

How to Use Recovery in Your Regimen

Adding active recovery into your training sessions can be done in two methods, and both are greatly beneficial to your recovery. The first is to add it into your current training session as soon as it has been completed, as a cool-down approach. This is where you will allow your body to ease itself out of your workout, allowing your heart rate and breathing to return to their normal states and reducing the amount of lactate in your blood. The lactate in your blood is an organic acid made by tissue and red blood cells in your muscles, which is what causes the muscle burn felt during exercise. This is the same approach as if you were driving your car and approaching a red light. Instead of slamming on the brakes to make the stop, you gently ease on the brakes for a gradual stop at the light. This same method applies to cooling down after a workout with respect to your heart rate and breathing, by going for a light walk or jog or adding in some dynamic and static stretches and yoga poses. The other option for active recovery is to incorporate this as a full active recovery day and implement the methods listed above as active recovery for the day, through swimming, walking, or yoga to name a few.

Both forms of recovery are crucial within your training cycle regimen to allow your body to find its balance repeatedly as you progress in your training. I highly recommend incorporating cool-down recovery, especially after high-intensity workouts and after fireground training sessions, for optimal recovery of the heart and body with at least one recovery day (active and passive) each week for maximum recovery and performance. In the end, listen to your body and what it is telling you. After all, it is the only place we truly have to live.
