• A.

60 degree

• B.

45 degree

• C.

75 degree

• D.

85 degree

C. 75 degree
Explanation
The correct angle of protection for a ladder to its base is 75 degrees. This angle ensures stability and prevents the ladder from tipping over while in use. It provides a balanced distribution of weight and minimizes the risk of accidents or injuries. A smaller angle may not provide enough support, while a larger angle can make the ladder unstable and prone to falling. Therefore, 75 degrees is the optimal angle for ensuring safety and stability while using a ladder.

### What is the "Least" preferred method to mitigate any risk as per heirarchy of control

• A.

Elemination

• B.

• C.

Engineering Control

• D.

Use of PPEs

D. Use of PPEs
Explanation
The "Least" preferred method to mitigate any risk as per the hierarchy of control is the use of PPEs. This is because PPEs only provide protection to the individual wearing them, rather than addressing the hazard at its source. Elimination, administrative control, and engineering control are considered more effective methods as they aim to eliminate or minimize the hazard itself, rather than relying on personal protective equipment.

### While lifting material we should keep our back

• A.

Horizontal to ground

• B.

Inclined

• C.

Straight

• D.

Oblique

C. Straight
Explanation
When lifting material, it is important to keep our back straight. This is because maintaining a straight back helps to distribute the weight evenly across the spine and reduces the strain on the muscles and ligaments in the back. It also helps to maintain proper alignment of the spine and reduces the risk of injury, such as muscle strains or herniated discs. Lifting with a straight back promotes good posture and ensures that the lifting force is generated from the legs rather than the back, which is safer and more efficient.
