Top 10 Health & Safety Risks in Construction

Top 10 Health & Safety Risks in Construction


Construction is a vital industry, building the infrastructure that shapes our world. But behind the progress lies a sobering reality: construction sites are inherently dangerous.  According to the Bureau of Labor Statistics, in 2021, construction had the highest number of fatal work injuries (1,008) out of all private industry sectors in the United States [BLS construction fatalities].

This doesn't have to be the case.  By prioritizing safety and taking preventative measures, we can significantly reduce these risks and ensure everyone goes home healthy at the end of the day.  In this countdown, we'll explore the top 10 health and safety hazards lurking on construction sites, and what you can do to protect yourself and your fellow workers.  Let's begin!

10. Airborne Dust and Fibers (Silica, Asbestos)

Construction sites are often filled with dust and fibers that can be harmful if inhaled. These tiny particles can irritate the lungs and lead to serious health problems down the line.

  • Health Risks:  Exposure to dust containing silica can cause silicosis, a debilitating lung disease.  Asbestos fibers, if inhaled, can lead to mesothelioma, a form of cancer.
  • Protection Methods:
    • Proper Ventilation: There are two main types of ventilation systems used on construction sites to control dust:
      • Local Exhaust Ventilation (LEV):  These systems use hoods or enclosures placed directly at the source of dust generation, such as near power tools or during demolition activities.  The hoods capture dust before it can disperse into the air, and a fan removes it from the work area through a duct system.
      • General Ventilation Systems:  These systems use fans to circulate air throughout the workspace, diluting dust concentrations and promoting fresh air intake.  This is often achieved by strategically placed fans pushing clean air in and exhausting dusty air out.
    • Dust Masks:  Wear properly fitted respirators with appropriate filtration levels (e.g., N95 or P100) depending on the dust type.
    • Dust Suppression Systems:  These systems work by spraying a fine mist of water into the air, which binds to dust particles and weighs them down, preventing them from becoming airborne. This is particularly effective for controlling dust generated from activities like demolition, excavation, and soil movement.
    • Training on Hazardous Materials:  Workers should be trained to recognize hazardous materials like asbestos and take appropriate precautions.

9. Electrical Hazards

Electricity is essential on construction sites, powering tools, lights, and temporary power systems. However, its improper use or malfunction can have devastating consequences.

  • Health Risks:  Electrical hazards can cause serious injury or death through electrocution, burns, and muscle spasms. Electrical current passing through the body can disrupt the heart rhythm, leading to cardiac arrest. Burns from electrical contact can be severe and require extensive medical treatment.
  • Protection Methods:
    • Ground Fault Circuit Interrupters (GFCIs):  Always use GFCI-protected outlets on construction sites. These devices detect imbalances in electrical current and quickly shut off power to prevent serious shocks.
    • Properly Insulated Wires:  Inspect electrical cords and tools regularly for damage to the insulation.  Never use frayed or exposed wires.
    • Qualified Electricians:  All electrical work, including installations, repairs, and modifications, should be performed by qualified and licensed electricians.
    • Safe Work Practices:  Follow safe work procedures when using electrical equipment:
      • Don't operate equipment with wet hands or while standing in water.
      • Never overload circuits or extension cords.
      • Always unplug tools and equipment before performing maintenance or repairs.
      • Use lockout/tagout procedures to de-energize equipment before working on it.
    • Personal Protective Equipment (PPE):  In some situations, additional PPE like insulated gloves and boots may be necessary to protect against electrical hazards.

spacebands can help automate PPE reminders by reminding users in certain areas that they need to wear PPE, by giving them a prompt on their spacebands wearable device.

4. Collapses (Trench cave-ins, Scaffolding failures)

Construction sites often involve excavations and working at heights, creating a constant risk of collapses.  These incidents can have catastrophic consequences, burying or crushing workers beneath tons of debris.

  • Health Risks:  Trench cave-ins and scaffolding failures can cause serious injuries or death from suffocation, crushing, and blunt force trauma.  Workers trapped under collapsed materials may also face risks of secondary injuries from prolonged pressure or exposure to hazardous materials like dust or fumes.
  • Protection Methods:
    • Trench Shoring:  When digging trenches, proper shoring systems are essential to prevent cave-ins.  These systems support the trench walls, preventing soil from collapsing inwards.  The type of shoring used will depend on the depth and soil conditions of the trench.
    • Safe Work Practices for Trenches:  Workers entering trenches should be properly trained on safe work practices, including proper entry/exit procedures, inspecting the trench walls for stability, and having a designated lookout to monitor the surrounding area.
    • Scaffolding Inspection and Erection:  Scaffolding must be erected, inspected, and maintained by qualified personnel in accordance with safety regulations.  Guardrails and fall protection systems should be properly installed on all scaffolding platforms.
    • Limited Access and Weight Restrictions:  Clearly mark and restrict access to areas beneath scaffolding to prevent anyone from being present in case of a collapse.  Enforce weight limits for materials and personnel allowed on the scaffolding to maintain its structural integrity.
    • Soil Testing:  For excavation work, conduct thorough soil testing to determine its composition and stability.  This information is crucial for selecting the appropriate shoring system and ensuring worker safety.

3. Slips, Trips, and Falls

Slips, trips, and falls may seem like minor incidents, but they are a leading cause of injuries on construction sites.  Uneven surfaces, debris, poor lighting, and improper footwear can all contribute to these accidents, leading to anything from sprains and bruises to serious fractures and head injuries.

spacebands offers a trips and falls feature, detecting a fall with the use of an internal gyroscope built into the wearable device. If a wearer remains immobile, an alert is sent out to nearby wearables for assistance.

  • Health Risks:  The severity of injuries from slips, trips, and falls varies depending on the distance fallen and the surface landed on.  However, these incidents can result in broken bones, sprains, strains, cuts, and even head injuries.  Serious falls from height can be life-threatening.
  • Protection Methods:
    • Housekeeping:  Maintaining a clean and clutter-free work environment is crucial.  Debris, tools, and materials should be properly stored or disposed of to avoid creating tripping hazards.
    • Surface Conditions:  Ensure walkways, ramps, and working surfaces are kept clean, dry, and free of slip hazards.  Promptly clean up spills and address uneven surfaces or damaged walking areas.
    • Proper Footwear:  Workers should wear appropriate safety footwear with good traction to provide grip on various surfaces.  Steel-toed boots may also be required depending on the work being performed.
    • Lighting:  Adequate lighting throughout the worksite is essential for clear visibility and to avoid tripping hazards in poorly lit areas.
    • Safe Work Practices:  Encourage safe walking practices, such as maintaining good posture, being aware of your surroundings, and avoiding distractions while walking or carrying objects.  Use handrails whenever available, and pay attention to changes in elevation or uneven surfaces.

2. Working at Height

Construction work often involves activities at elevated levels, from rooftops and ladders to scaffolding and suspended platforms. These working-at-height situations present a significant risk of falls, which can be the leading cause of serious injuries and fatalities on construction sites.

spacebands' working at height feature detects when a worker begins working at height and reminds them to wear the correct PPE - giving employees a timely reminder and employers a paper trail to protect against claims.

  • Health Risks:  Falls from height can have devastating consequences.  Depending on the distance fallen and the surface landed on, injuries can range from broken bones and sprains to severe spinal cord damage, head trauma, and even death.
  • Protection Methods:
    • Fall Prevention Measures:  The hierarchy of controls prioritizes fall prevention over fall arrest.  This means prioritizing measures that eliminate the need to work at height whenever possible.  For example, prefabricating building components on the ground and then hoisting them into place can minimize the need for workers at elevated locations.
    • Guardrails and Fall Arrest Systems:  When working at height is unavoidable,  guardrails and fall arrest systems are crucial safety measures.  Guardrails provide a physical barrier to prevent falls, while fall arrest systems (like harnesses and lifelines) are designed to catch a worker if they do happen to fall. Both systems must be properly installed, inspected, and maintained to ensure effectiveness.
    • Safe Work Practices:  Workers performing tasks at height should be properly trained on safe work practices. This includes using fall protection equipment correctly, inspecting equipment before each use, maintaining three points of contact (two hands and a foot or vice versa) whenever possible, and avoiding leaning over unguarded edges.
    • Competent Supervision:  Competent supervisors should oversee work at height, ensuring workers are following safety procedures and using fall protection equipment appropriately.
    • Ladders:  When ladders are the only feasible option for accessing elevated areas,  ensure they are properly secured, extend at least three feet above the landing surface, and are not used as a work platform for extended periods.

1. Worker Fatigue

Construction work can be demanding, both physically and mentally. Long hours, strenuous activity, and exposure to the elements can all contribute to worker fatigue. While fatigue might not seem like an immediate danger, it significantly increases the risk of accidents and injuries on construction sites.

  • Health Risks:  Worker fatigue can impair judgment, reaction time, coordination, and focus. This makes workers more susceptible to slips, trips, falls, and mistakes when operating machinery or performing complex tasks.  Fatigued workers are also less likely to recognize or respond to safety hazards promptly.  Chronic fatigue can also lead to health problems like weakened immune systems and increased risk of cardiovascular disease.
  • Protection Methods:
    • Proper Rest Breaks:  Enforce mandatory rest breaks throughout the workday to allow workers to recover from physical exertion and mental strain.  Provide adequate breaks for hydration and meals as well.
    • Scheduling Considerations:  Schedule demanding tasks during cooler parts of the day when possible to minimize fatigue caused by heat and exertion.
    • Monitoring for Fatigue Signs:  Train supervisors to recognize signs of worker fatigue, such as drowsiness, irritability, difficulty concentrating, or increased clumsiness.  Workers should also be encouraged to communicate when they are feeling fatigued and need a break.
    • Flexible Work Arrangements:  Consider implementing flexible work arrangements, such as rotating schedules or compressed workweeks, to help manage fatigue and workload.
    • Promoting a Culture of Safety:  Create a work environment where prioritizing safety and taking breaks is encouraged, not seen as a sign of weakness.  Open communication about fatigue and its risks is crucial for preventing accidents.
