Biological Risk Hazards

Risk Factors in Construction

Construction work is dynamic, diverse, and constantly changing; this presents a significant challenge in protecting the health and safety of construction workers. Workers are at risk of exposure to many different types of hazards, which can result in physical injury, illness, disability, or even death.

In construction, change is constant.

Here is a list of factors that increase the health and safety risks for workers on construction sites:

  • Constantly changing jobsite environments and conditions affect the health and safety of workers. Constant change is the most common factor causing injuries and illnesses in construction.
  • Multiple contractors and subcontractors may create hazards unknown to others due to poor communication and coordination.
  • High turnover and unskilled laborers result in a lack of awareness of hazards.
  • Lack of education and training on hazards and safe work practices.
  • Diversity of work activities that happen simultaneously quickly create new hazards.
  • Exposures to health hazards arise both from their own work and from nearby activities.
