How to Mitigate: 

• Install safety guards, barriers, and protective devices on machinery to prevent workers from coming into contact with moving parts or hazardous areas.
• Provide training for workers on the safe operation of machinery and the recognition of potential pinch points 
• Establish clear communication protocols (e.g. radios) for signaling and coordinating activities around machinery
• Regularly inspect and maintain machinery and equipment to ensure they are in good working condition 
• Set up exclusion zones around operating machinery and hazardous areas where workers are not permitted to enter
• Provide appropriate Personal Protective Equipment and ensure the PPE is worn correctly
• Ensure that machinery and materials are stored safely and that pathways are kept clear of obstructions

5. Slips, Trips, and Falls

The constantly changing nature of construction sites, such as the movement of materials and equipment, can create hazards that are difficult to anticipate. 

Poor maintenance of walkways, ladders, and scaffolding can contribute to unsafe conditions that lead to accidents. Slippery surfaces, uneven terrain, and debris can cause workers to slip, trip, or fall, leading to injuries.

How to Mitigate: 

• Keep work areas clean and free of debris, tools, and materials that can create tripping hazards. Promptly clean up spills
• Install non-slip mats or coatings in areas prone to wet or oily conditions
• Use cable covers or secure wires and hoses to prevent them from becoming tripping hazards
• Ensure that ladders and scaffolding are in good condition, properly positioned, and used according to safety guidelines
• Require the use of appropriate safety footwear with slip-resistant soles to improve traction on various surfaces
• Use guardrails, barriers, and toe boards around edges, open holes, and elevated platforms to prevent falls
• Educate workers on the risks associated with slips, trips, and falls, and train them on safe work practices
• Perform regular safety inspections of the construction site to identify and address potential slip, trip, and fall hazards. Implement corrective measures as needed

6. Exposure to Hazardous Materials

Prolonged or acute exposure to hazardous materials can lead to serious health problems, including respiratory issues, skin conditions, cancer, and other long-term diseases. Without proper safety measures and controls, workers may be exposed to harmful substances, especially if they are not adequately informed or equipped to handle these materials.

How to Mitigate: 

• Identify and label all hazardous materials on-site
• Provide appropriate Personal Protective Equipment for workers handling hazardous materials
• Implement engineering controls such as ventilation systems, fume extractors, and enclosed work areas to minimize exposure to hazardous materials
