How to make your inspection checklists effective, efficient,  and EASY!

Step 1: Check Personal Protective Equipment (PPE)

Personal Protective Equipment (PPE) is vital for shielding workers from hazards on the job and ensuring adherence to U.S. safety regulations. Use this guide to confirm all necessary equipment is on hand and ready for use.

Verify All Required PPE is Available

Make sure every team member has the proper gear. Here's what should be included:

• Head protection: Hard hats or safety helmets equipped with visors and hearing protectors.
• Eye and face protection: Safety glasses, goggles, and face masks certified under ANSI Z87.1-2015.
• Hearing protection: Earplugs or protectors with a minimum SNR rating of 32 dB.
• Body protection: Hi-vis jackets, trousers, and vests that repel water and dirt, offering protection from high-pressure cleaning and hydraulic fluids.
• Hand protection: Durable, waterproof gloves with textured surfaces for better grip. Look for gloves with an inner nylon layer and a nitrile rubber coating, tested for resistance to cuts, abrasions, tears, and punctures.
• Foot protection: Steel-toed boots that are waterproof and reinforced to handle pressurized liquids and hydraulic fluids up to 500 bar/7,500 psi.
• Respiratory protection: Necessary when dealing with dust or harmful airborne particles.

Check PPE Condition and Fit

Inspect each piece of equipment for damage. Hard hats should be free of impact marks or UV damage, and safety glasses must have clear, scratch-free lenses with intact frames.

Verify that protective clothing is still water-repellent and undamaged by chemicals. Gloves should maintain their grip and show no cuts or punctures, while steel-toed boots need to provide solid protection with watertight seams.

Fit is just as important as functionality. Loose PPE can snag on equipment and fail to protect properly, while tight-fitting gear can limit movement and lead to fatigue. Adjust safety glasses so they stay secure, and ensure hard hats fit snugly without slipping during work.

Environmental factors also play a role in PPE performance. In hot conditions, opt for ventilated hard hats and breathable clothing. If flying debris is a concern, confirm that face shields provide full coverage and are securely attached.

Confirm Safety Standard Compliance

All PPE must meet current U.S. safety standards for the job at hand. For example, face and eye protection should carry ANSI Z87.1-2015 certification, guaranteeing impact resistance and optical clarity.

Some specialized equipment goes beyond the basics. TST safety helmets, for instance, are tested to withstand liquids at pressures up to 3,000 bar/43,500 psi. Similarly, TST protective boots can handle high-pressure hydraulic fluids up to 500 bar/7,500 psi. Gloves should also be rated for high resistance to cuts, abrasions, tears, and punctures.

Match your PPE to the specific risks at the job site. For example, underground utility work may require non-conductive materials to avoid electrical hazards, while chemical cleaning demands gear resistant to the specific chemicals being used. High-pressure tasks need equipment capable of withstanding the maximum pressures expected.

Keep a record of PPE compliance as part of your pre-job safety checklist. This documentation not only supports regulatory inspections but also helps track when equipment needs replacement or upgrades. Once PPE is verified and compliant, move on to assess the physical safety systems of your equipment in Step 2.

Step 2: Inspect Equipment Safety Systems

Keeping equipment in good working order is essential to avoid accidents and downtime. This step focuses on verifying safety features and components before starting operations.

Check Equipment Physical Condition

Start by giving the equipment a thorough once-over to catch potential issues early. Look at hoses and their connection points for signs of leaks, cracks, or bulges. Pay special attention to the boom-mounted vacuum intake hose - its brackets should be secure and show no signs of wear.

Move on to the pumps and tanks, including water and debris tanks. Look for any wear or leaks that might compromise their functionality.

Inspect the nozzles carefully. Watch out for buildup, inconsistent pressure, erratic spraying, or any signs of damage like cracks or corrosion. If you spot any of these issues, clean the nozzles, perform maintenance, or replace them as needed. Lastly, make sure all system connections are tight and secure.

Also, check that all moving parts are properly shielded to prevent accidents.

Test Emergency Safety Controls

Don’t skip testing emergency safety controls. These systems are critical for protecting operators and others on-site in case of unexpected equipment failure or hazards.

Check Moving Parts and Safety Guards

Once the physical inspection is complete, turn your attention to moving parts and safety guards. Unprotected moving parts can pose serious risks, so confirm that all safety shields and guards are firmly in place. Suction lines and hoses should also be positioned away from work areas to minimize the chance of accidental contact.

After completing these checks, you’ll be ready to assess potential hazards at the job site.

Step 3: Review Job Site Hazards

Once you've confirmed that all equipment is safe to use, it's time to assess potential hazards on the job site. Identifying and addressing these risks early can prevent serious accidents and ensure a safer work environment.

Mark Work Areas and Identify Utilities

Start by clearly marking your work zone and locating any underground utilities. Contact your local utility marking service well ahead of time to ensure underground lines are accurately identified, following all local regulations.

Use bright spray paint or flags to outline excavation boundaries, adding a buffer zone beyond the planned dig area. Double-check utility locations with proper detection tools, especially in areas near buildings, sidewalks, or driveways where utilities are often concentrated.

Set up barriers like traffic cones, caution tape, or temporary fencing to secure the work zone. These barriers should extend far enough to keep unauthorized individuals at a safe distance and protect against hazards like high-pressure water.

Evaluate Environmental and Site Risks

Environmental factors can significantly impact safety. Pay attention to soil conditions - loose or sandy soil can be unstable, while rocky terrain might cause unpredictable challenges. Look out for overhead hazards like power lines or tree branches, and keep an eye on the weather. Strong winds or storms can increase risks and should be factored into your planning.

Always maintain a safe distance from electrical lines. If working closer is unavoidable, consult with the local utility provider to mitigate the risks.

Check the ground stability where the hydro-excavation truck will be stationed. If the surface seems unstable, consider using steel plates or timber mats to create a more secure platform. Also, identify and address slip or trip hazards by removing obstacles or marking them clearly. Be mindful of nearby pedestrian or vehicle traffic that could interfere with the work zone.

Install Warning Signs

Place warning signs at key entry points to the work area, clearly indicating that high-pressure water operations are underway and that only authorized personnel are allowed inside.

If there’s a risk of debris flying beyond the immediate excavation site, include signs to warn of this hazard. For projects near roadways, follow the Department of Transportation's guidelines for traffic control and lane closures. Coordinate with local authorities if necessary to manage traffic disruptions.

In high-traffic areas or on longer projects, electronic message boards can provide continuous updates about work status or detours. Make sure all signs are highly visible, positioned at eye level, and updated or removed promptly once the work is complete.

With hazards properly identified and precautions in place, you’re ready to move on to verifying operator qualifications and procedures.

Training records should cover key areas such as operating high-pressure systems, assessing soil conditions, following safety protocols, complying with environmental regulations, conducting preventive maintenance, troubleshooting, and managing job site procedures.

Additionally, confirm that all regulatory training requirements are met. For example, organizations like Cal/OSHA mandate specific training schedules for various safety topics. Some training is required at the start of employment, some annually, and others before specific tasks or when procedures change. Critical topics include hazard communication, PPE usage, and respiratory protection.

Operators must also meet regulatory definitions of "Qualified Person" and "Competent Person." A Qualified Person demonstrates expertise through training and experience, while a Competent Person is authorized to identify and correct hazards on the job. The level of qualification required may vary based on the task and location.

Set Up Communication Methods

Clear communication is vital to preventing accidents and ensuring smooth hydro-excavation operations. Establish reliable primary and backup communication systems, such as radio channels with tested protocols and backup batteries. In areas with poor reception, standardized hand signals can be used.

For noisy environments or work near roadways, visual signals become even more critical. Ensure the equipment operator has an unobstructed view of ground personnel, and agree on specific signals for commands like "start", "stop", "move left", and "emergency shutdown."

Document the communication plan and assign responsibilities. Designate one person as the primary communicator with the equipment operator to prevent confusion caused by multiple people issuing instructions.

Go Over Emergency Response Plans

Reviewing emergency response procedures ensures that every team member knows their role and can act quickly in a crisis.

Identify the locations of emergency shutdown controls and train at least two crew members on how to operate them efficiently. Discuss the nearest medical facilities and confirm that someone on the team holds a current first aid certification. Keep emergency contact numbers easily accessible and verify that cell phone coverage is sufficient at the job site.

Emergency scenarios should be practiced during training sessions to make responses second nature. These drills should cover equipment malfunctions, utility strikes, injuries, and incidents like spills or environmental releases. Quick, decisive action during emergencies can prevent a bad situation from escalating.

Assign clear roles for emergencies. Identify who will provide first aid, contact emergency services, shut down equipment, and secure the area. Always have backup personnel in place in case the designated responder is unavailable.

With operator training, communication methods, and emergency plans in place, the team is ready to move on to final documentation.

Step 5: Complete Required Documentation

Once the equipment is inspected and operators are trained, the next step is to complete all necessary documentation. This step is crucial not only for compliance but also for maintaining a clear record for future reference.

Check Pre-Job Forms and Permits

Before starting work, ensure all pre-job checklists are filled out and every required permit is obtained.

For tasks like entering petroleum or petrochemical tanks, you’ll need a Confined Space Entry Permit in accordance with OSHA 1910.146. If the project involves hydro-excavation, contact 811 to locate underground utilities and use ground-penetrating radar (GPR) for additional documentation.

Water discharge permits may also be required under the Clean Water Act (CWA) if hydro-excavation activities affect local water systems. Keep in mind that state and local regulations might impose extra rules, such as noise limits, water discharge restrictions, or specific operating hours. To avoid delays, reach out to your local permitting office early in the planning process to identify all applicable requirements.

Update Inspection and Maintenance Records

Ensure all inspection and maintenance logs are current and detailed.

Daily inspection records should include the condition of critical components like high-pressure hoses, emergency shutdown systems, and protective guards. These records demonstrate that your equipment is properly maintained and safe to use. Maintenance logs should document scheduled services, parts replacements, and repairs, including dates, technician signatures, and detailed descriptions of the work performed. Don’t forget to keep calibration certificates for pressure gauges and monitoring equipment up to date.

Verify Legal Requirements

Double-check that your project complies with all local, state, and federal regulations.

Utility location is a must. Confirm that all underground utilities are accurately marked and that locate tickets are valid for the entire project duration. If markings expire - which often happens after a set period defined by the marking service - make sure to request new locates.

Environmental compliance is equally important. Properly document the disposal of excavated materials, especially if dealing with specific soil types or contaminated areas that require special handling. Record the disposal site and method used for all materials removed.

Worker safety documentation should align with OSHA standards for your activities. Keep updated records of training sessions, safety meetings, incident reports, and certifications. Additionally, maintaining daily logs and photographic evidence of excavation activities ensures compliance and provides a solid reference for future needs.
