Answer
Explanations
1
Juma, a carpenter, needs to reach a high shelf to retrieve some timber. He's considering an old, wobbly chair. What's the most appropriate and safest raised platform for Juma to use in this situation?
B. A sturdy step ladder
A sturdy step ladder is specifically designed for safe, temporary elevation. The other options (old tires, overturned bucket, rickety box) are unstable and not intended for this purpose, significantly increasing the risk of a fall.
2
During a construction project, a worker is painting a ceiling. The provided scaffolding has loose planks and no guardrails. What's the most immediate risk associated with working on this raised platform?
D. Falling from a height
A raised platform with loose planks and no guardrails presents a direct and immediate risk of a fall. While other risks may exist, falling is the primary and most dangerous consequence of such platform instability and lack of safety features.
