Importance of Fire Prevention

During Hot Work OperationsHot Work is any work involving burning,welding, or similar operations that are capable ofinitiating fires or explosions. This program shall

cover the following hot work processes: Welding and Allied Processes

Heat Treating

Grinding

Thawing Pipe Powder-Driven Fasteners

Hot Riveting

Similar Applications Producing a Spark, Flame or

During Hot Work OperationsMay, 2001

University of Kentucky

A building that housed the universitypresident and other offices was destroyed by a

fire that apparently was started by welding on

the roof. The building, which had been

constructed in 1882, was undergoing a $1.3million renovation.

During Hot Work OperationsApril, 2003

University of Florida

Sparks from welding equipment caused a firethat forced the evacuation of several hundred

people at the J. Hillis Miller Science Center.

The fire started while a worker was repairing

the ventilation system. Two peoplecomplained of smoke inhalation and all the

research animals were exposed to the smoke.
