Before starting heavy equipment in cold weather (e.g., -20°C), what should an operator check in addition to the standard pre-operation inspection?

Question: Before starting heavy equipment in cold weather (e.g., -20°C), what should an operator check in addition to the standard pre-operation inspection?

Answer options:

• If the air conditioning is working. ✅ The battery charge, engine oil viscosity, and signs of frozen components (e.g., air brakes).
• The radio station preset settings.
• The quantity of personal snacks available.

Correct answer: The battery charge, engine oil viscosity, and signs of frozen components (e.g., air brakes).

Explanation: Cold weather significantly impacts equipment. Operators must specifically check battery health (cold reduces capacity), oil viscosity (thicker oil causes harder starts), and for any frozen air lines in braking systems to prevent malfunctions and damage.
