Hydro-Excavation & Vacuum Truck Safety Checklist

Inspect all tires for proper inflation, cuts, bulges, and adequate tread depth (minimum 4/32 inch).

Air brake system reaches 120 psi within 2 minutes at 1200 RPM; low-pressure buzzer sounds correctly @ 60 psi. Inspect air lines for leaks.

Verify all lights (headlights, taillights, brake lights, turn signals, hazard lights) are functioning correctly. Check audible backup alarm.

Inspect vacuum unit relief valves for proper operation and ensure they are free from obstructions. Test functionality daily.

Verify static grounding cables are securely connected to the vacuum unit and the grounding rod. Check for corrosion or damage.

Inspect vacuum hose and water wand hose for cuts, abrasions, kinks, and proper connections. Ensure hose clamps are secure.

Check engine oil, coolant, hydraulic fluid, and other fluid levels. Replenish as needed.

Verify the horn is functioning properly.

Ensure windshield wipers are in good condition and functioning properly.

Inspect all seatbelts for proper function and condition.

Confirm fire extinguisher is fully charged, inspected within the last year, and readily accessible.

Verify all underground utilities have been located and clearly marked per 811 or local regulations. Confirm markings match site plans.

Confirm a valid excavation permit has been obtained, if required by local regulations.

Assess soil type and stability to determine appropriate excavation methods and shoring requirements, if necessary.

Ensure adequate traffic control measures are in place to protect workers and the public. Verify signage and barricades are properly positioned.

Assess weather conditions (wind, rain, temperature) and adjust work practices accordingly. Suspend operations during severe weather.

Evaluate the excavation area for potential confined space hazards. Implement confined space entry procedures if necessary.

Inspect the stability of excavation slopes. Ensure proper sloping or shoring is in place to prevent cave-ins.

Ensure safe access and egress to the excavation area. Provide ladders, ramps, or other means of access as needed.

Assess the proximity of nearby structures and utilities. Take precautions to prevent damage during excavation.

Maintain a clean and organized work area. Remove debris and tripping hazards.

Verify hard hat is ANSI Z89.1 compliant, undamaged, and properly fitted.

Ensure safety glasses or face shield are ANSI Z87.1 compliant and provide adequate eye protection.

Confirm hearing protection (earplugs or earmuffs) is available and used when noise levels exceed 85 dBA.

Verify high-visibility clothing (vest or jacket) is ANSI 107 compliant and worn at all times.

Ensure appropriate gloves are worn to protect hands from cuts, abrasions, and chemical exposure.

Verify steel-toe boots are worn to protect feet from impact and compression hazards.

Assess the need for respiratory protection based on air quality. Provide and ensure proper use of respirators if required.

Ensure waterproof clothing is available and worn during wet conditions to prevent hypothermia.

Verify sunscreen and appropriate clothing are available for sun protection.

Verify water pressure is within safe operating limits for the task and equipment. Do not exceed manufacturer's recommendations.

Ensure proper water wand operating techniques are used to minimize risk of injury and damage to utilities. Maintain a safe distance from utilities.

Position vacuum hose to prevent back-pressure and ensure efficient material removal. Avoid sharp bends or kinks in the hose.

Establish clear communication signals between the water wand operator and the vacuum truck operator.

Ensure a spotter is present to monitor the excavation area and provide warnings of potential hazards.

Adhere to safe digging practices, including slow and controlled excavation, and probing to verify utility locations.

Follow proper backfill procedures to ensure adequate compaction and prevent settlement.

Dispose of excavated material in accordance with environmental regulations and company policies.

Verify emergency shutdown procedures are understood and readily accessible.

Identify and respect 'no spray' zones near sensitive equipment or areas.

Verify vacuum truck operators are properly trained and certified to operate the equipment.

Ensure utility locators have completed required training and are qualified to locate underground utilities.

Confirm a site-specific safety plan has been developed and communicated to all workers.

Verify Material Safety Data Sheets (MSDS) or Safety Data Sheets (SDS) are readily available for all chemicals used on site.

Ensure an emergency contact list is readily available and includes contact information for local emergency services, utility companies, and company personnel.

Review daily inspection logs for the vacuum truck and hydro-excavation equipment. Ensure any deficiencies have been addressed.

Confirm a Job Hazard Analysis (JHA) or Task Hazard Analysis (THA) has been completed for the hydro-excavation task.

Verify regular toolbox talks are conducted to discuss safety topics and reinforce safe work practices.

If applicable, confirm a confined space entry permit is completed and posted.
