What do I do when working under lift without checking overhead obstructions?
Tap to open
📖 Verified core answer
Stop and check the lift path before moving or raising. Look up, down, behind, and around the platform before the duct becomes the only thing you see.
🛠️ Field verification checklist
- Check floor/ground condition.
- Scan overhead for pipe, lights, cable tray, sprinkler, deck, and finished work.
- Keep duct and tools inside the platform limits.
- Use a spotter in tight areas.
- Stop if people or material enter the lift path.
🗣️ Ask the foreman
Route options
🚫 Do not do this
Do not drive, raise, or swing the lift while focused only on the duct in front of you.
Why this matters
Lift problems usually happen because the platform is moving through space, not just because the wheels are rolling.

What do I do when not knowing when ladder work should become lift work?
Tap to open
📖 Verified core answer
If the task needs force, time, awkward reach, or duct handling, it is probably not ladder work anymore. Get a lift/scaffold or ask before climbing.
🛠️ Field verification checklist
- Inspect the ladder before use.
- Set it on stable ground and keep the correct angle.
- Keep your belt buckle between the rails.
- Use the ladder for access, not wrestling duct.
- Ask for a lift/scaffold when the task is high, long, heavy, or awkward.
🗣️ Ask the foreman
Route options
🚫 Do not do this
Do not stand on the top step, lean sideways, or muscle duct overhead from a bad ladder position.
Why this matters
A ladder is a way to reach the work; it is not a stable duct-install platform.

What do I do when forgetting gloves/eye protection before cutting sharp metal?
Tap to open
📖 Verified core answer
Stop before cutting. Gloves and eye protection go on before the blade hits metal, not after the first sharp offcut lands.
🛠️ Field verification checklist
- Put on cut-resistant gloves and approved eye protection.
- Check who is below or beside the cut.
- Control the offcut before it falls or twists.
- Use the right snips/shear/grinder for the material.
- Ask if the cut needs a face shield, dust control, or hot-work control.
🗣️ Ask the foreman
Route options
🚫 Do not do this
Do not cut sharp sheet metal bare-handed or without eye protection.
Why this matters
