This operation involves several significant hazards that require careful risk assessment and mitigation. Here's a breakdown of potential risks and control measures:

1. General Hazards:

• Powered Mobile Equipment Operation: The use of rock trucks and bulldozers presents risks of collisions, rollovers, and equipment failure. Ensure all operators are trained and certified . Conduct daily equipment inspections and maintenance. Establish clear communication protocols and traffic management plans. Ensure equipment has rollover protective structures and seatbelts .

• Slips, Trips, and Falls: Uneven ground, especially on the berm, can lead to slips, trips, and falls. Maintain good housekeeping practices, ensure adequate lighting, and require appropriate footwear. Provide fall protection measures (e.g., safety harnesses and guardrails) where necessary, especially on the elevated berm.

• Dust and Noise: Hauling and spreading dirt can generate significant dust and noise. Implement dust control measures (e.g., water spraying) and provide hearing protection to workers. Monitor air quality and noise levels to ensure compliance with occupational exposure limits.

2. Wastewater Facility Hazards:

• Exposure to Hazardous Substances: Operating within a wastewater facility may expose workers to various chemical and biological hazards. Conduct a hazard assessment to identify potential contaminants and implement appropriate control measures, such as PPE (gloves, respirators, etc.) and hygiene protocols. Ensure workers are trained on WHMIS (Workplace Hazardous Materials Information System) .

• Confined Space Entry: Wastewater facilities often contain confined spaces (e.g., tanks, manholes). If entry into confined spaces is required, follow proper confined space entry procedures, including atmospheric testing, ventilation, and standby personnel.

• Vehicle/Personnel Interaction: Increased vehicle traffic in the facility increases the risk of collisions with workers. Implement strict traffic control measures, including speed limits, designated routes, and spotters. Ensure high-visibility clothing is worn by all personnel.

3. Railway Crossing Hazards:

• Train Collisions: Crossing an active railway line poses a significant risk of train collisions. Coordinate with the railway authority to establish safe crossing procedures. Use a designated signaller to ensure clear visibility and communication. Implement a positive stop system to prevent vehicles from entering the tracks without authorization.

4. Irrigation Pond/Berm Hazards:

• Falling from Height: Dumping dirt from a 25ft wide surface on top of an 80ft tall berm presents a significant fall hazard. Implement engineering controls such as guardrails or berm extensions to prevent equipment and personnel from falling over the edge. Ensure operators are trained in safe dumping procedures and use spotters to guide them.

• Equipment Rollover: Operating heavy equipment on a berm can lead to rollovers, especially if the surface is uneven or unstable. Regularly inspect the berm for stability and implement measures to prevent erosion or collapse. Ensure the bulldozer has rollover protection .

• Instability of the Berm: The added weight of the dirt could compromise the structural integrity of the berm. A professional engineer should assess the berm's load-bearing capacity and provide recommendations for reinforcement or stabilization.

5. Excavator Operation

• Safe Digging Practices: When digging or leveling, use appropriate techniques to maintain machine stability and prevent damage . Avoid rapid movements and ensure the machine is positioned correctly for the task . Be aware of underground facilities .

Control Measures (Hierarchy of Controls):

1. Elimination: Can the need to cross the railway be eliminated by using an alternate route? Can the height of the berm be reduced to minimize fall hazards?
2. Substitution: Can smaller equipment be used to reduce the load on the berm?
3. Engineering Controls: Install guardrails on the berm, use remote-controlled equipment for dumping, improve railway crossing signals.
4. Administrative Controls: Implement safe work procedures, traffic management plans, training programs, and permit systems.
5. Personal Protective Equipment (PPE): Provide hard hats, safety glasses, high-visibility clothing, hearing protection, and respiratory protection as needed.

Monitoring and Review:

• Regularly inspect the work site for hazards and ensure control measures are effective.
• Conduct safety meetings to discuss potential risks and reinforce safe work practices.
• Review and update the risk assessment as needed, especially if there are changes to the work process or environment.
• Investigate all incidents and near misses to identify root causes and prevent recurrence.
