REPORTING 19 1.5 A LAYMAN S PERSPECTIVE OF FIRE AND OF 19 CHEMICAL
LABORATORY ANALYSIS METHODS. WHY DO FIRES OCCUR? WHERE DOES THE CHEMIST
FIT IN? 1.5.1 A PRIMER ON FIRE. WHAT CHEMICAL AND 20 PHYSICAL PROCESSES
ARE RESPONSIBLE FOR FIRES? 1.5.2 THE SCOPE OF CHEMICAL ANALYSIS FOR
ACCELERANTS 24 WHAT IS AN ACCELERANT AND HOW CAN THE CHEMIST FIND IT?
1.5.3 TECHNICAL ASPECTS OF ANALYSIS. ARE THERE 28 INSTRUMENTS FOR THE
DETECTION OF ACCELERANTS DIRECTLY AT THE FIRE SCENE? WHY IS IT NECESSARY
TO CARRY OUT CHEMICAL ANALYSIS IN THE LABORATORY RATHER THAN IN THE
FIELD? 1.5.3.1 SAMPLE PREPARATION. WHAT IS DONE TO A FIRE 28 DEBRIS
SAMPLE BEFORE IT IS ANALYZED? WHAT METHODS ARE AVAILABLE? 1.5.3.2
INSTRUMENTAL ANALYSIS. HOW DOES ANALYTICAL 30 INSTRUMENTATION WORK? WHAT
SORT OF RESULTS DOES IT PRODUCE? ARE THESE MACHINES RELIABLE? 1.5.3.3
DATA INTERPRETATION. HOW DOES THE CHEMIST DECIDE 33 WHETHER A FIRE
DEBRIS SAMPLE CONTAINS AN ACCELERANT? 1.6 ETHICAL AND PROFESSIONAL
