Hot Work Safety Slogan

“When you’re welding, cutting or grinding,
Take precautions to avoid the binding
Of sparks and flames that can ignite,
And turn a safe job into a fright.

Inspect your work area, clear of debris,
And check your equipment before you proceed.
Wear your PPE and keep it on tight,
To protect yourself from any dangerous light.

Stay aware of your surroundings,
And keep a fire extinguisher handy,
For any emergencies that come unbounding,
So you can put out the fire on the spot, oh so dandy.

Hot work is a dangerous game,
But with proper preparation, it can be tamed.
So take heed and take care,
And your hot work will go off without a scare.”        (By:-  Mr. O P Arya)

 What is Hot Work ?

Hot work refers to any work that involves the use of equipment or processes that generate heat, sparks, or flames. This includes welding, cutting, brazing, soldering, grinding, and other similar activities that use heat or sparks to melt, cut, or shape materials.
