Question: You are operating a backhoe and notice a severe hydraulic fluid leak originating from a ruptured hose, causing the boom to slowly drift downwards unexpectedly. What is your immediate action?

Answer options:

• Attempt a temporary repair of the hose using tape or a clamp. ✅ Position the bucket safely on the ground, then shut down the engine and tag out the equipment.
• Immediately call for a mechanic to assess and repair the leak.
• Continue working carefully, monitoring the fluid level closely.

Correct answer: Position the bucket safely on the ground, then shut down the engine and tag out the equipment.

Explanation: A major hydraulic leak causing uncontrolled movement is a significant safety hazard. The immediate action is to secure the machine by safely lowering the boom/attachment to the ground, shutting down the engine to prevent further operation and fluid loss, and then 'tagging out' the equipment to prohibit its use until repairs are safely completed, as per lockout/tagout procedures (e.g., CSA Z460).
