Minimum safe distance from pool fires

Radiation heat transfer is a primary reason for fire growth. Experimental d ata are needed to clarify the ignition potential and time required to ignit e a particular target second item. The concepts of critical heat flux and t hermal response parameter are important to the material ignition problem. T he objective of the present contribution is to clarify these important radi ant ignition concepts and to exemplify a range of realistic calculations re lated to real-world situations.
