Where would Construction Be Without Intumescent Material?

By John Rakic

 

It was around 30 years ago when I first heard the word “intumescent”. Little did I know that day would change my working life. It took me ages to remember how to spell it and to pronounce it correctly.

 

If I’m honest, this word and the phenomena of intumescing has been a huge part of my working life.

 

So, what is it?

 

Simply put, to intumesce—the verb which comes from the Latin word “intumesco”—means to swell up (“I become swollen”).

 

It is fair to say that passive fire protection (or fire stopping) has adopted the word, and intumescent materials are well known to those who work in this field.  Read More

 

 

Smoke Is The Real Killer in Fires

By John Rakic

 

They say that time flies. Well, that saying holds true to me personally when it comes to smoke and smoke leakage. I am fortunate to have spent six years completing a Masters in Fire Safety Engineering, studying on weekends and evenings while working full time. I had a thirst for knowledge and passion to learn how to calculate and model smoke movement.

 

This all manifested itself in my major project or dissertation for my master’s degree being smoke leakage. I have fond memories of the time I spent in Madison Wisconsin, doing ambient and medium temperature air or smoke testing. I tried to correlate the empirical formulas of Coopers and other researchers with actual leakage measurements. Read more.

 

 

 

A Guide to Fire Stopping of Service Penetrations for Active Fire Protection Companies

By John Rakic

 

We can thank Fredrick Grinnell all those years ago, as he is credited for being the creator of the first practical automatic fire sprinkler.

 

Here in Australia, the Wormalds have been leaders in fire protection design, installation, and servicing since their inception in 1989 as Wormald Brothers. The company was formed more than 125 years ago now, by Joseph Dawson Wormald and Henry Percy Wormald, to introduce Grinnell’s sprinkler technology to Oceania.

 

So called active or water-based fire protection systems have saved thousands of lives and billions of dollars of property. For an effective fire protection strategy, we need early detection; safe egress paths, smoke control measures, fire compartments, fire brigade intervention and fire stopping of opening in fire barriers around services through which fire and smoke can spread. Read more.

 

 

 

Passive Fire Protection of Air Conditioning and Refrigeration Services

By John Rakic

 

Australian Building Regulations have been slowly tightening up to improve the energy efficiency of our buildings. This article will talk about what these changes mean to the services for HVAC&R pipe reticulation as well as the challenges this presents to passive fire protection and the fire stopping of openings in fire barriers where these services need to pass through.

 

What we see is a slow increase in the thickness of insulation required on copper pipes and pre-manufactured and insulated pair coil materials (used for split system type air conditioners, for example). Read more.
