Why the LPG Cylinders are exploding, during fire?

Have you ever had a doubt, why the LPG cylinders are exploding, during fire?



The Explosion, (the sudden release of blast wave) is one of the major reasons for the damage to buildings and injury to occupants during LPG leaks.

If the cylinder is not exploded during fire, most of the building damage and risk to neighborhood’s can be minimized.

Let’s come to the answer,

  • If the LPG Cylinder is subjected either to fire or any other heat source, the liquefied petroleum will change in to gaseous state. (As temperature increases the liquids will convert to gaseous stage )
  • If it is continuously subjects to heat, than the contents of LPG will restore to gaseous stage, which increases the internal pressure inside the Cylinder.
  • Though the Liquid space of the cylinder absorbs the heat and sinks, but in the gaseous space (the space above the liquid space) will not have any medium to reduce the heat, so most of the energy will be absorbed by the Cylinder.
  • If the cylinder subjected to heat, it will starts to melt and on a certain stage it will fail, in which the sudden release of pressurized gas space comes out as an explosion.

What to do when LPG Smell found in Home?

LPG Cylinders are most hazardous, which can kill the entire occupant’s in home.
Do you believe, all you family members, knew the action to take, when the LPG smell founds in kitchens or home.



Absolutely, the answer will be “No”

Imagine, if your mom or sister or any of your family member are not aware the actions to take in case of LPG Leaks, what will happen, even it cannot be imagined.

So here we are talking about the serious issue, which is worthy to read further,


If you have a doubt that the LPG may leak from cylinders, follow this 7 proven and tried steps to keep yourself safe.

  1. Turn off the regulator & valve both in LPG cylinder & stove
  2. Do not turn on or turn off any switches such as lights or fan (the minor spark produced from the switches can act as an ignition source and may leads to explosion)
  3. Open all your windows & doors to allow the LPG gas too dilute
  4. Get all your family member’s outside the home
  5. Do not try to seal or repair the leaks from yourself, hence you are not person trained in it.
  6.  Call to the supplier or agent, from whom you purchased the LPG cylinders.
  7. Inform the situation & wait until they arrive and repair.

What is the scope of Industrial Safety Diploma & Engineers?


What is the scope of Industrial Safety Diploma & Engineers?

“What is the Scope of industrial safety diploma”


The common questions among the students wish to take industrial safety engineering courses,



Workplaces are becoming unsafe; due to the number of factors such us,


The use of large machinery,
The use of hazardous chemicals,
The use of high voltage electricity,
The presence of excessive noise, vibration, heat etc,


The ILO Declared


“Every 15 Seconds a worker met an accident in his workplace”



Hope now, you can understand “How hazardous the industries are”


It’s not easier to perform the entire industrial activities safely, without separate mechanisms and manpower to control it.


Also, we cannot perform the Industrial activities without using machines, chemicals, electricity etc.


So the Industries need a competent Industrial safety engineers who knows “the casual factors of accidents and the methods to control it”


Also In every countries the Companies having a legal requirement to appoint competent

“Industrial safety engineers”


If the company fails to appoint competent industrial safety engineers to manage their risks, the companies may incur enforcement notices, criminal fines from the government authorities.

And now the awareness among the industries are grows up and the trade unions and insurance companies are insisting health and safety in the workplace.


Finally,


As technology and science increases, the probability of accidents and occupational ill-health also increases.

So the Industrial safety engineers will find a huge demand in the market in upcoming years.
