Barnett Research


TP 2004/1; 2005/2 and 2007/1 are Technical Publications prepared for the NZ Chapter of the Society of Fire Protection Engineers.

NZ SFPE TP 2004/1 is the result of an extensive mathematical analysis covering 800 pages of calculations and graphs based on floor areas varying from 100 to 5000 m², fire load energy densities ranging from 400 to 2000 MJ/m², ventilation openings ranging from 2% to 20% of the floor area and stud heights ranging from 2.4 to 6.0 metres.  Two useful flow rate formulas were developed, one being proportional to the fire intensity in MW, and the other being proportional to the total fire load in MJ.

NZ SFPE TP 2005/2 provides calculation methods for determining water storage for fire fighting purposes.  This is a ground-breaking study in that it uses fire engineering to demonstrate that the water storage volume can be related to the total fire load in MJ. Many fire codes use non-scientific methods to arrive at the required storage volume.

NZ SFPE TP 2007/1 provides detailed comparisons of eleven different methods used worldwide for calculating water requirements needed for firefighting purposes

Cliff Barnett New Zealand:

Cliff Barnett, a NZ Consulting Civil and Fire Protection Engineer, has studied fires and fire fighting flow rates since he was guest speaker at the 50th Jubilee Year Conference of the Institute of Fire Engineers held in New Zealand in 1979. He is the author of over 45 technical papers including some in international journals and at symposiums.  He is the author of “BFD Curve” in Fire Safety Journal 37. This paper was prepared from a large data base of over 140 test fires which is available free on request to crb@crb.co.nz

Cliff is widely experienced in investigating the cause and origin of fires including deaths and murder by fire.

In the 2005 Queen’s Birthday Honours, Cliff was awarded a medal for his services to fire safety engineering.
