A telehandler is operating in an open yard where gusts of wind are measured at 60 km/h. The operator is about to lift a large, flat sheet of plywood (1.2m x 2.4m, 100 kg). The telehandler's manual specifies a maximum safe operating wind speed for lifting such loads of 40 km/h. What is the primary concern?

Question: A telehandler is operating in an open yard where gusts of wind are measured at 60 km/h. The operator is about to lift a large, flat sheet of plywood (1.2m x 2.4m, 100 kg). The telehandler's manual specifies a maximum safe operating wind speed for lifting such loads of 40 km/h. What is the primary concern?

Answer options: ✅ The dynamic forces exerted by the wind on the large surface area of the plywood, which can significantly contribute to lateral tipping.

• The wind will cause the engine to overheat due to increased resistance.
• The plywood will likely be damaged by the strong wind before it can be secured.
• The telehandler's fuel consumption will dramatically increase due to wind resistance.

Correct answer: The dynamic forces exerted by the wind on the large surface area of the plywood, which can significantly contribute to lateral tipping.

Explanation: Wind acting on loads with large surface areas creates significant dynamic forces (sail effect). Exceeding the manufacturer's specified wind limits (60 km/h vs. 40 km/h limit) dramatically increases the risk of lateral tip-over, as outlined in CSA B354.7 and CCOHS guidance on environmental hazards.
