L2B Blog: Fire Risks

Fire Risks


Since the early dawn of man, the discovery of fire has brought us progress in every way. A discovery that has pushed the human race beyond grunting and digging for roots, catapulting us into the future. It has provided us with warmth, transport, cooked meals and a living environment that is far more convenient and healthy.
Fire brings a risk of injury and/or death. The importance of treating fire with respect and a mental presence is pertinent to everyone’s wellbeing. This article will give you an overview of some of the risks that fire brings.

Fire requires three elements to start; heat, fuel & oxygen. Stupidity might be added as a fourth for a safe measure as this seems to be a common factor. Examples of fire hazards will include but are not limited to: objects generating heat, faulty electrical equipment, overloading of power supply sockets, smoking, human error and negligence as well as meteorological events (lightning).

 

Hoarding is considered to be one of the major contributors towards fire hazards. Hoarding is defined as the persisted collection and accumulation with an inability to relinquish a large number of objects. Hoarding might include variable objects and materials that humans collect and store causing clutter that will be the fuel for any fire. The rule of thumb is that if you haven’t used it for two months then get rid of it. It is not worth getting your mono-brow or ponytail singed by fire as a direct cause of your hoarding.

Whilst the list of materials posing possible fire risks is endless, the common list would include: flammable liquids of all kinds, gas, and fabric etc. It is of value to know the flash point of flammable material that you might utilise and or store on your premises.

The flashpoint of a volatile flammable material is the lowest temperature at which the vapours of the material will ignite when given an ignition source. The flash point is often confused with the autoignition temperature, which is the temperature at which the vapour ignites spontaneously on its own without an ignition source. The fire point is the lowest temperature at which the vapours of the material will continue to burn after being ignited and the ignition source has been removed. The fire point is higher than the flash point because at the flashpoint more vapour may not be produced rapidly enough to sustain combustion. Flammable materials almost always have a Material Safety Data Sheet that will include information in regards to the particular materials flash/ignition point. It is of value to take the time to read and familiarise yourself with this data if you are inclined to handle the material in an environment that could cause it to ignite.

 

 Whilst it is common knowledge as to the danger linked to well-known flammable materials, the risk of fire is hidden in materials that we do not commonly associate with fire. Ordinary cake flour is one of these products. In its original solid form, it has no risk of ignition. However, when converted into a fine dust, the risk of ignition increases exponentially. Other organic materials that fall into this category will include but are not limited to: grain, starch, sugar, powdered milk, cocoa, coffee, and pollen.

Fireball spreads rapidly:

So, if waking up from a “Rip Van Winkle” coma with your favourite little dog named “Skippy” imprinted as a vague Bushman drawing on your kitchen wall doesn’t appeal to you, then rather don’t celebrate your perfect ginger-bread man biscuits by applauding yourself with a hand full of flour over your ignited gas stove.

Be aware and educate yourself on all aspects of fire.

Did You Know #DYK: How To Extinguish Different Kinds of Fire?

posted in: Did You Know 2

How To Extinguish Different Kinds of Fire?

Did you know that in order for a fire to exist there must be four elements present? The four elements are namely oxygen to sustain combustion heat to raise the material to the correct temperature, fuel to support combustion and a chemical reaction – (Oxygen + Heat + Fuel) = Chemical reaction. This very simple formula will determine the extinguishing agent you need to be using in order to put out your fire.

How many people just run for water when there is a fire?

Unfortunately, it is not that simple!

Let me simplify the concept of fire and how we can extinguish these fires:

 

Types of fire:

Class A – Ordinary combustion, these are flammable materials and these fuels the source e.g. Wood, cloth, paper and even your basic day to day trash.

Class B – This fire source uses flammable liquids e.g. petroleum, different kind of tars, oils and even paint.

Class C – Energized electrical equipment/components e.g. Computers, servers, motors, transformers and our daily appliances.

Class D – Combustible metals e.g. magnesium, titanium, sodium, lithium and potassium – these are mainly present in a laboratory environment.

Class K – Cooking oils and greases – We all cook meals with either vegetable or animal fats and these are the components that can start this fire.

Now that we know about and understand the different classes of fire, let’s discuss our different options for extinguishing these fires.

 

The different types of fire extinguishers:

  1. Water – The water extinguisher has a cooling effect on the burning agent causing the fire to burn more slowly.
  1. Powder – Dry powder extinguishers smother the fire and form a barrier between the fuel and the oxygen that is allowing the fire to ignite.
  1. Foam – Foam extinguishers have a cooling effect on the burning agent, creating a barrier between the flame and the fuel that is causing the reaction.
  1. Carbon dioxide – CO2 Extinguishers suffocates the fire allowing it to kill off the oxygen that is reacting with our fuel source.
  1. Wet Chemical – Wet Chemical extinguishers work by creating a layer of foam that prevents the oxygen from fuelling the fire. It creates a cooling effect and kills the fire.

 

The last thing we will be discussing to solve all your fiery situations are which fire extinguisher types to use for the different classes of fire:

Type Class A Class B Class C Class D Class K
  Combustible Materials Flammable Liquids Electrical Equipment Combustible Metals Cooking Oil & Gas
Water x x x x
Foam x x x
Dry Powder x
CO2 x x x
Wet Chemical x x x

L2B Blog: History of Hard Hats

.History of Hard Hats

History of Hard Hats

Hard Hats; a common symbol of the Construction Industry, but have you ever stopped to wonder about the History behind this safety accessory?

History

According to Prescot Valley Tribune, “The Hard Hat originated with Edward Bullard, a WWI veteran. He brought a steel helmet home after the war. This metal headgear was the inspiration to revolutionize industrial safety. Bullard’s father worked in the industrial safety business for 20 years and sold protective hats, but they were made of leather.

Construction of the Hoover Dam, which began in 1931 was the first project in which construction workers were required to wear Hard Hats. Later, in 1933, the construction site of the Golden Gate Bridge became America’s first “Hard Hat Area”.”

The first Hard Hats were made from:

  • Leather
  • Canvas
  • Steel
  • Aluminum
  • Fibreglass
  • Plastic
  • and finally today’s High-Density Polyethylene (HDPE).
Functionality

The function of the Hard Hat is pretty obvious. If worn and fitted correctly it provides limited safety from shock, perforation, fire, water and heat.

Hard Hats also provide a form of identification.

A wearer can use colour coded Hard Hats to differentiate between job titles/responsibilities:

  • White – Managers, Engineers, Supervisors/Foremen
  • Blue – Electricians, Carpenters and other technical operators (besides civil workers)
  • Green – Safety Officers
  • Red – Fire Fighters
  • Yellow – Labourers
  • Brown – Welders and workers with high heat application
  • Grey – Site Visitors

These colour codes are general and could change according to the Project.

Over time Hard Hats, like most things also need replacing. As a wearer, you should inspect your Hard Hats before each use.  Your support strap should also be replaced annually and the entire hat every five years. Hard Hats may also allow for the attachment of safety accessories; most noteworthy are face shields, respirators, hearing protection and work lamps.

Future

Today’s Hard Hat hasn’t changed much since the 1960’s and has become a staple of safety, but they may be getting an upgrade in the future.

According to Sourceable, “In Australia, RMIT has developed a system whereby sensors can be embedded onto safety glasses, helmets or boots and can monitor and inform workers of impending danger…”
Sounds really interesting, after all, technology is a part of our every day lives and why not safety too.
Industry leaders can achieve much by ‘upgrading’ the Hard Hat. For example, by monitoring and assessing stats you can take precautions; not only in the present but also in the future through behavior analysis. But this may also present issues; like how much monitoring is too much when it comes to privacy and tracking? What are your thoughts?

In conclusion, the future sure looks safe when it comes to Hard Hats. The History of Hard Hats was certainly an interesting topic to research and blog.

Finally

Do you have any Hard Hat stories or facts you’d like to share? Or do you frequently use one?
