Question

what should you do before raising the forks or platform on your lift truck?
make sure the lift truck has stopped moving.
check above for sprinkler heads, light fixtures, or other obstructions.
step off the deadman pedal.
sound your horn and yell \clear!\

Explanation:

When operating a lift - truck, safety is crucial. Raising the forks or platform while the truck is moving can cause instability and potential accidents. Checking for overhead obstructions like sprinkler heads or light fixtures is also important to avoid damage to the lift - truck and the infrastructure.

• Option 1: Making sure the lift - truck has stopped moving is a fundamental safety step. If the truck is in motion while the forks/platform are being raised, the load can shift, and the truck can tip over.
• Option 2: Checking above for obstructions (sprinkler heads, light fixtures, etc.) is necessary. If there are obstructions, raising the forks/platform can damage both the lift - truck and the overhead items.
• Option 3: The deadman pedal is a safety feature that keeps the lift - truck in a safe state when depressed. Stepping off it is not a correct pre - raising step.
• Option 4: Sounding the horn and yelling "Clear!" is more of a general warning before moving or operating the lift - truck rather than a specific pre - raising step.

Answer:

A. Make sure the lift truck has stopped moving, B. Check above for sprinkler heads, light fixtures, or other obstructions.
