WHAT IS A HOT WORK ?
Hot Workmeans an open flame,
welding arc, non-explosion proof
electrical tools or equipmentand
any heat source, capable of causing
ignition.

•Management and Supervisors
must assure that Fitters,
Welders and their Helpers
are trained.
•All ID badges of workers
involved in Hot work, must be
color coded.
•Supervisor, Fitters,Welders and

PROTECTIVE CLOTHING
Protective clothing required for welding and
burning varies with the size, nature and
location of the work to be performed;
•Only fire resistant clothing must be worn;
•All welders shall use flameproof gloves;
•Clothes should be free from oil and grease;
•Flameproof leather (or suitable material)
aprons should be considered if long-term
exposure to radiant heat or sparks is
anticipated.

HOT WORK PERMIT
A Hot Workpermit system is
devised and used whenever
welding, cutting or bracing is
to be done.
Hot work permit is being
prepared by the Supervisor
and or the Leadmaninvolved
in Hot work activities
(enclosed / attached to the
Daily Safe Work Plan).
