Show answer & explanationAnswer & explanation
Correct answer: D. Musculoskeletal injuries from improper lifting.
The primary safety concern when handling and installing large, heavy stone countertops is the risk of musculoskeletal injuries, such as strains, sprains, and back injuries, due to improper lifting techniques or inadequate lifting equipment.
Why the other options are wrong
- A. Chemical burns from sealants are a potential hazard, but generally lower risk and less common than lifting injuries for this type of task.
- B. Cuts from sharp edges are a risk, but usually less severe than musculoskeletal injuries from lifting heavy objects.
- C. Silica dust is a concern during cutting or grinding stone, but not typically during the handling and installation of pre-fabricated countertops.
Heavy Material Handling Safety
Practices and procedures to prevent injuries when moving and installing heavy construction materials, emphasizing proper lifting techniques, mechanical aids, and team lifting.
- Musculoskeletal disorders (MSDs) are the most common injuries.
- Utilize dollies, carts, forklifts, or cranes whenever possible.
- If manual lifting is necessary, use proper body mechanics and team lift.
Memory trick: Heavy stone, don't lift alone, protect your back, make it known.
