Safety Tips for Conducting Sewer Inspections

Working around manholes and conducting sewer inspections can be hazardous without the right precautions. Here are key safety tips for inspections that all professionals should adhere to:

Use Proper Personal Protective Equipment (PPE):

Ensure all personnel are equipped with safety gloves, hard hats, eye protection, and steel-toed boots. Respiratory protection may also be required in case of toxic gases.

Test Air Quality Before Entry:

Always perform a gas test to check for hazardous gases like:

• O2 – Oxygen
• CO – Carbon Monoxide
• H2S – Hydrogen Sulfide
• CL2 – Chlorine

Ventilation is Crucial:

When entering confined spaces, use proper ventilation techniques to ensure adequate airflow, reducing the risk of gas buildup. Mechanically ventilate if entry is required.

Fall Protection During Sewer Inspections:

Secure the area around the manhole to prevent falls. Use guardrails or barricades and harnesses if necessary.

Traffic Control:

Set up visible signs, cones, and barriers if the manhole is near traffic. Ensure proper traffic control procedures are followed to keep workers safe.

Manhole Inspection / Entry:

Use caution & proper tools when moving manhole covers. Visually inspect conditions, i.e. high flow, surge, etc.

Communication:

Maintain clear and constant communication between team members, especially when operating robotic sewer inspection equipment, to ensure everyone’s safety.

Training and Emergency Preparedness:

Ensure workers are trained in confined space entry procedures and are equipped with emergency response plans in case of accidents.

Environmental Hazards:

Wash down equipment either in or above manhole and be sure to practice good personal hygiene. Don’t take the sewer home with you!

By following these safety tips for sewer inspections, workers can minimize risks and ensure a safer environment.
