Heavy rain and sudden flooding create immediate, severe safety hazards on our work sites. Under the Nova Scotia Occupational Health and Safety (OHS) Act, employers and supervisors have a legal duty to provide a safe workplace, and workers have the right to know about hazards and refuse unsafe work.

Identified Hazards

• Trench & Excavation Collapse: Rainwater quickly saturates soil, making trench walls unstable and highly prone to sudden cave-ins.

• Electrical Shock Risks: Water conducts electricity. Standing water near power tools, extension cords, or electrical panels introduces a severe electrocution hazard.

• Slips, Trips, and Falls: Mud, slick surfaces, and hidden holes under murky puddles drastically increase fall injuries.

• Contaminated Water: Floodwater frequently carries biohazards, sewage, chemicals, and sharp debris.

Safe Work Practices & Controls

• Stop Trench Work: Cease all work in open excavations during heavy downpours. A competent person must re-inspect and re-certify the trench before anyone re-enters.

• De-energize Wet Areas: Immediately turn off and disconnect power sources in areas where water is pooling. Never handle electrical equipment with wet hands or while standing in water.

• Wear Appropriate PPE: Ensure you are using high-traction waterproof boots, heavy-duty gloves, and high-visibility rain gear suitable for low-visibility conditions.

• Secure the Site: Cover vulnerable materials, anchor loose lightweight equipment that could float away and clearly mark flooded hazards with barricade tape.

Your Rights as a Worker in Nova Scotia

Under Section 43 of the NS OHS Act, you have the legal Right to Refuse Unsafe Work if you reasonably believe that the conditions (such as severe flooding or an unstable trench) pose a danger to your health or safety. Report any such hazards to your supervisor immediately.
