Key Hazards
- Traffic exposure during emergency response
- Flooding, erosion, or undermined pavement
- Unstable ground around the break
- Stored pressure in water mains and fittings
- Contact with other underground utilities
- Slips, trips, cold stress, or contaminated water exposure
2–3 Minute Talk Script
Water main break response often happens under pressure, with water flowing, traffic nearby, customers affected, and the public watching. The urgency of restoring service should not override worker safety.
The scene should be evaluated before workers move in. Water flow, traffic, erosion, pavement damage, flooding, overhead hazards, nearby utilities, and public exposure all need to be considered.
Traffic control is often one of the first safety priorities. Breaks may occur in streets, intersections, shoulders, sidewalks, or parking lots where drivers may be distracted by water, equipment, lights, or workers.
Flowing water can undermine pavement, shoulders, sidewalks, and soil. Workers should avoid standing on surfaces that may be hollow, cracked, eroded, or unsupported beneath the surface.
Water pressure and stored energy must be respected. Valves, fittings, clamps, pipe sections, and hydrants can move or fail if pressure is not controlled properly.
Excavation hazards may develop once digging begins. Soil stability, water accumulation, spoil placement, utility locating, access, and protective systems should all be addressed.
Workers should consider exposure to water, mud, sewage cross-contamination, chemicals, sharp debris, and cold weather. PPE should match the conditions and the response work.
A safe water main break response controls the scene first. Protect the crew from traffic and unstable ground, manage pressure, locate utilities, and communicate clearly before rushing into the repair.
Safety Reminders
- Evaluate the scene before entering the work area.
- Set up traffic control early.
- Watch for undermined pavement, erosion, and unstable ground.
- Control pressure before working on pipe or fittings.
- Locate and protect nearby underground utilities.
- Use excavation safety controls during digging.
- Wear PPE suitable for water, mud, weather, and debris.
Ask the Crew
- Is traffic control adequate for the response location?
- Could pavement or soil be undermined by flowing water?
- Has water pressure been controlled before repair work begins?
- Are other underground utilities located and protected?
- What excavation, water exposure, or weather hazards are present?
