Safety Distances and Equipment Rules

After completing the worksite survey outlined in Protocol 3, it’s time to enforce safety distances and equipment rules. Use the utility markings and ground evaluations from Protocol 3 to determine the minimum separation distances required. Always follow the minimum separation guidelines set by local regulations and utility providers.

When operating equipment, follow these key practices:

• Set up equipment on stable, level ground
• Ensure proper grounding when working near electrical utilities
• Use the manufacturer’s recommended pressure settings and hose angles

Clearly mark safety zones around any identified hazards to keep the worksite secure.

Worker Training Requirements

Before operating equipment, workers must undergo safety training. A thorough program should include:

• Procedures for operating specific equipment
• Managing slurry and vacuum systems
• Recognizing and avoiding hazards
• Emergency shutdown steps and response plans
• Proper communication methods, including hand signals

Keep detailed records of all training and certifications. Update training programs whenever there are changes to standards or equipment.

5. Team Safety Communication

Clear communication is key to avoiding accidents. Use these signals and alerts to ensure everyone stays informed and safe.

Hand Signals

Hand signals are a quick and effective way to communicate on-site:

• Raised fist: Stop all equipment immediately
• Thumbs up: Message understood or all clear
• Horizontal arm sweep: Maintain distance or stay back
• Pointing down: Reduce pressure or lower equipment
• Pointing up: Increase pressure or raise equipment
• Crossed arms: Shut the system down
• Hand to ear: Switch to radio communication

Radio Protocol

When using radios, follow these guidelines:

• Stick to the assigned channels for your team.
• Always state your location and reason for calling.
• Confirm every instruction you receive.
• Use “Emergency-Emergency-Emergency” to signal urgent situations.
• Keep radios silent during critical operations unless absolutely necessary.
