Firefighter Station Gear: Cotton TShirts vs Polartec vs ??

So which TShirt is safer under your turnout? Cotton or PolarTec  or ?

Traditionally firefighters have been issued standard cotton tshirts worth about $10 for their standard station wear and these are the tshirts that they practice in and wear under their turnouts.
Is there any benefit to other types of tshirts?  This blog posts gives you some information in order to help make that decision.

There are numerous studies out there regarding this issue.  You can check them out at;
NFPA 2112 Testing

You may want to avoid any underwear that is categorized as a thermoplastic.  Check this out;
What to wear under your turnouts

Here are some excerpts from ArcFlashWear
Selection of the 'perfect' FR textile and/or fibre is a complex process. Each FR textile or fibre has particular properties which either provides benefits or shortcomings. Textile manufacturers blend fibres in an attempt to balance these individual properties to maximise a textile's performance. It is imperative that assessing Corporations be aware of each fibre's properties to ensure that garments selected meet the specific requirements of a given application.

Mental and physical exertion increases the body's core temperature. Increased blood circulation and the production of perspiration cool the body down. This cooling down process can be disrupted due to improper textile heat and moisture management leading to problems with concentration, fatigue, muscle cramps, difficulties breathing and ultimately heat stroke. The excellent moisture management and breathability of FR fibres such as Lenzing FR®, Nomex®, Cotton, Kermel® and Wool, used in the manufacturing of premium FR work wear, lead to a reduction in the risk from this mortal danger.
Home laundering should be discouraged. Common household washing powders, soaps, detergents and fabric softeners are not suitable for laundering FR work wear. These ‘everyday used’ materials can remove the FR treatment from treated fabrics such as cotton and cotton/polyester. With inherent FR textiles, cleaning materials can cause a film or build-up within the fabric structure, which may itself combust should the garment be exposed to an ignition source. Home laundering also raises the possibly of transporting contaminates from the workplace to the home. Given the above, garment care labels show laundering instructions but sometimes only provide basic information. Corporations should seek further instructions from the garment manufacturer and display the instructions in appropriate workplace areas. At the time of issuing garments to employees, documented care and maintenance instructions should be provided.

The 2016 Canadian Consenus guidelines for First Aid and CPR.

2016 Canadian Consensus guidelines for First Aid and CPR

There are a number of different first aid training providers in British Columbia.  Does your training provider include anything from the 2016 Canadian Consensus guidelines for First Aid and CPR?

Spinal Precautions for First Responders

The times are a changing regarding Spinal Precautions in regards to better patient care but it is important to follow your level of training and protocols.

If you are curious what the current protocols are for Spinal Precautions according to BCAS then check it out at this site; https://bctg.bcas.ca/Condition/Principles/13

The medical principles in the BCAS document refer to an online course titled "Evolving Practices in Trauma Care".  I did a bit of research and believe I have found that course offered at;
https://www.itrauma.org/education/itls-etrauma/

The ITLS has a document outlining their thoughts on the use of long backboards, etc. just for patient extrication.  You can read about that at; https://www.itrauma.org/wp-content/uploads/2014/05/SMR-Resource-Document-FINAL.pdf

A really good article is "The Norwegian guidelines for the prehospital management of adult trauma patients with potential spinal injury". It states the following;
The vacuum mattress, while not rigid enough for extrication, is a useful transportation device. As vacuum is applied, the mattress moulds to the patient’s contours, minimising point pressure, making it more comfortable, less painful and, arguably, less likely to produce ulceration [, ]. The vacuum mattress has been shown to provide a similar, or superior, degree of stabilisation when compared to that of the backboard [, , , ].

According to the BCAS FR Intervention guidelines a FR is to provide manual stabilization and avoid any unnecessary movement.  (at one higher level up, an EMR is to Immobilize patient following principles of spinal immobilization).

The BCAS recently issued an advisory on how they will be changing their treatment guidelines.  This was done in the BCEHS Spinal Motion Restriction Briefing document.

Overdose Deaths in British Columbia and FR Protocols

If you are curious on the statistics on overdose deaths in British Columbia as of October 2017 look no further than just clicking this link.    You will find out that there were 1208 deaths in B.C. in 2017 of which the highest percentage occurs on Fridays.


If you are a first responder you can find read the BCEHS document on Administration of INTRAMUSCULAR Naloxone for Suspected or Confirmed Opioid Overdose.  Keep in mind that I do not believe that a First Responder is required to phone EPOS in order to get authorization to administer Naloxone.    The reason for that is that you can confirm the First Responder treatment guidelines at the BCEHS Treatment Guidelines for Central Nervous System Depressant Poisoning /Overdose

The Emergency Medical Assistants board of B.C. recommends that all first responders review safety when around Fentanyl by viewing this site;  https://www.fentanylsafety.com/

Firefighter Ladders and tieing the Halyard

Portable Ladders and Halyards
If you are studying for a firefighter exam, you know that the proper way to deploy a extension ladder, is as follows;
A) Select the proper ladder for the job
B) Remove the ladder from the apparatus
C) Carry the ladder to the worksite.
D) Raise the ladder (which may involve untying the halyard).
E) Extend the ladder and position.
F) Tie the halyard.






I was recently at a course, where the instructor, advised, that during emergency situation, the time that is spent dealing with tying of the halyard could probably be spent more efficiently doing something else.  Sure untying and tying off the halyard only takes seconds but since the halyard's only purpose is to raise the fly, then what is the point of tying it off, other than just getting it out of the way.

The following is copied directly from a firerescue 1 article;
On an extension ground ladder, the halyard is tied off to secure the fly section to the bed section when not in use. It is common to use a clove hitch knot, incorporating the halyard in the middle of the knot with the clove hitch tied around the third or fourth rung up from the bottom of the ladder.
This adds time when trying to deploy and raise the ladder. The time it takes to untie the knot, unwrap the rope and then extend the ladder will complicate the operation.
Instead, try tying the halyard around only the bottom rung of the bed section. This allows the ladder to be extended without having to untie the knot, thus saving time in the operation. If the rope needs to be tied off after the raise, the halyard can be tied using a clove hitch on a bight.

Piercing Nozzles - Some research....

This is a blog post regarding piercing nozzles, especially as they pertain towards use in residential structure fires. 

Under the right circumstances when a fire is compartmentalized and isolated in a confined space, using a piercing nozzle for extinguishment is safe, quick and efficient.
The piercing nozzle throws a 25-foot diameter, umbrella-type, spray pattern which, when converted to steam, can cover a 2,400 square foot area with dense fog. The steam cools the temperature of the fire gases, reducing the heat. It also cools the temperature of the fuel and displaces oxygen, thus smothering the fire.
In live fire tests conducted by the Hoquiam (Wash.) Fire Department, a fully-involved, normal-sized, room fire in a house was extinguished by a piercing nozzle in 6-8 seconds using 3-5 gallons of water. Again, under the right circumstances, using the piecing nozzle is excellent for booster tank attacks when there are a limited number of personnel or when the water supply is limited, delayed, or unavailable.

There are quite a few variations of piercing nozzles on the market.  Have a look...

Some information on tactics:
A piercing nozzle, particularly if fed by Class A foam or compressed air foam, may be a particularly effective tool on attic fires if it’s pushed through the ceiling and flowed into the attic from below. These nozzles can provide a widely distributed flow of the suppression agent, reaching all around the attic space. For larger buildings, such as garden apartments, two or more of these nozzles placed under a trench cut can make an awesome firebreak, stopping horizontal fire spread. Remember: When applying water overhead, you’re adding weight to the ceiling, which can increase the potential for a ceiling collapse.

There is quite a bit of research on the science of attic fires.
NIST - Simulation of an attic fire in a wood frame residence This involved a FF LODD.

The new Canadian National Fire Information Database is now available.  I can't wait to get access and map out where all the fires are happening.  Check out these stats - chimney fires (heating) are actually quite low according to stats.
