Pre-Task Plan: Highwall Scaling

Date: [DATE] Work Area: [WORK AREA] Task Supervisor: [SUPERVISOR NAME]

1. Task Description

Visually inspect the highwall for loose material and use hand tools (scaling bars, picks) to remove loose rock and debris to prevent potential falls.

2. Task Duration

Estimated Start: [START TIME] Estimated Completion: [END TIME]

3. Personnel Involved

Scaler
Spotter
Equipment Operator (if applicable)

4. Task-Specific Hazards and Controls

Hazard	Risk	Control Measures
Falling rocks/debris	Injury to personnel below	Establish a clear exclusion zone. Use spotters to warn of falling material. Scale from top to bottom whenever possible. [1]
Instability of highwall	Highwall collapse, potential for burial	Conduct thorough geotechnical assessment. Implement proper slope support techniques. Monitor highwall for signs of instability (cracks, bulging).
Dust inhalation	Respiratory irritation, silicosis (long-term)	Use respirators (NIOSH approved). Implement dust suppression methods (water spraying). [2]
Slips, trips, and falls	Injuries from loss of balance	Ensure good footing. Wear appropriate footwear. Use fall protection equipment when working at heights.
Manual handling of tools	Musculoskeletal injuries	Use proper lifting techniques. Take frequent breaks. Rotate tasks to reduce strain.

5. Required PPE for Today's Task

Hard hat
Safety glasses or goggles [2]
Steel-toed boots
Gloves
Respirator (NIOSH approved) [3]
High-visibility vest
Fall protection harness and lanyard (if applicable)

6. Tools and Equipment Needed

Scaling bars
Picks
Shovels
Rock hammer
Air compressor (if using pneumatic tools)
Water sprayer for dust suppression
Communication devices (radios)

7. Pre-Start Checklist

Area Preparation

[ ] Establish and clearly mark exclusion zone.
[ ] Ensure adequate lighting.
[ ] Check stability of the highwall face.

Equipment Checks

[ ] Inspect scaling tools for damage.
[ ] Verify proper functioning of fall protection equipment.
[ ] Check communication devices.

Communication

[ ] Conduct pre-task briefing with all personnel.
[ ] Establish clear communication signals between scalers and spotters.

8. Task Steps Overview

Conduct a visual inspection of the highwall.
Establish exclusion zone and post warning signs.
Begin scaling from top to bottom, removing loose material.
Use spotters to monitor for falling rocks and debris.
Regularly assess the stability of the highwall.

9. Emergency Response for This Task

Rock fall causing injury → Provide immediate first aid, call for emergency services, clear the area.
Highwall collapse → Evacuate the area immediately, account for all personnel, notify supervisor.

10. Task-Specific Precautions

Never work directly below another scaler.
Be aware of changing weather conditions.
Do not scale if the highwall is wet or icy.

Pre-Task Briefing Confirmation

All workers understand the task, associated hazards, and required controls.

Rosie, the contractors' AI Admin & Risk Assistant, works across the operational workflows to take care of the busy work, make capture in the field effortless, surface risk, and create business-ready outputs—without removing human judgment.

Rosie was grounded in a curated, human-created, SALUS-verified source library and retrieved relevant material for each question. SALUS published the English answer exactly as generated after duplicate screening. Francis Langlois reviewed the English content.

Rosie was offered as a free tool so people could ask real workplace-safety questions and receive immediate guidance. SALUS is preserving these human-requested answers because the same questions recur across jobsites and safety teams, and because the resulting threads can help people compare experience, clarify guidance and find relevant supporting material.
