Question

	Wearing ear plugs are usually violated by workers
	Goggles offers sufficient protection during all welding operation
	Respiratory protection is more vital than other protection equipment
	There are four classes of respirators
	The degree of combustibility depends largely upon the volatility of the material

. Mark with (P/T ) for correct statements or (O/F) for incorrect statements

Answer 1

Wearing earplugs are usually violated by workers= (P/T )

Reason- In many types of research it has been found that employees tend to avoid using earplugs due to the discomfort caused to them

Goggles offer sufficient protection during all welding operation= (O/F)

Reason= For any kind of welding operations, the employees must use the goggles and hand shield or helmet equipped with a suitable filter glass

Respiratory protection is more vital than other protection equipment=(P/T )

Reason- Respiratory protection are important as they protect the employees from various types of respiratory hazards

There are four classes of respiratorst=(P/T )

Reason = mouth bit respirator,quarter-mask, half-face mask, and full facepiece are the four types of respirators

The degree of combustibility depends largely upon the volatility of the material=(P/T )

Reason- composition-specific vapour pressure is the important factor that determines the degree of combustibility that depends largely upon the volatility of the material
