No-Preventive Maint Records
ACCIDENTS INVESTIGATION : THE CAUSES TREE ANALYSIS METHOD
Major findings from the accident investigation
The root causes (latent failures) consisted of :
Room was having wooden partition made of sound skulpt ( Dry Grass ) within which thermo acoustic material had been packed. This is highly combustible material
18 years old Concealed wiring. Opening (doors, window) are not of self closing nor fire retardant.
