Survey Safety01:28

Survey Safety

Surveying near highways, rough terrain, or power lines involves significant risks. Working along highways is particularly dangerous and requires the use of warning signs and flagmen. It is safest to avoid working directly on roads and use offsets whenever possible. When highway work is unavoidable, it must follow all safety guidelines. Surveyors should wear bright clothing, such as orange reflective vests, to ensure visibility to motorists, coworkers, and hunters. In construction zones, wearing...
Obedience01:08

Obedience

According to obedience research, we may harm others under the forceful pressures of an authority figure (Milgram, 1974). How about if the inappropriate orders were delivered with less force? The increasing interdependence between nurses and physicians compelled Hofling and his colleagues to explore nurses’ reactions to a potentially harmful medical request made by the perceived authority figure, the doctor (Hofling, Brotzman, Dalrymple, Graves, & Pierce, 1966). In this situation, obedience...
Community Based Intervention01:30

Community Based Intervention

Community-based interventions in mental health represent a paradigm shift from institution-centered care to treatments embedded within the fabric of local communities. By prioritizing inclusion and leveraging existing societal structures, this approach fosters a supportive environment conducive to addressing mental health challenges while promoting individual dignity and agency.

Persuasion Strategies01:52

Persuasion Strategies

Researchers have tested many persuasion strategies, including the foot-in-the door and the door-in-the-face techniques, in a variety of contexts. Ultimately, the principles are effective in selling products and changing people’s attitude, ideas, and behaviors (Cialdini & Goldstein, 2004).
Ethics in Research01:56

Ethics in Research

Today, scientists agree that good research is ethical in nature and is guided by a basic respect for human dignity and safety. However, this has not always been the case. Modern researchers must demonstrate that the research they perform is ethically sound.

Area of Science:

  • Occupational Health and Safety
  • Construction Management
  • Behavioral Science

Background:

  • High injury rates in the construction industry necessitate effective safety interventions.
  • Evidence-based safety interventions specific to construction are limited.
  • Leader-based safety interventions show greater efficacy than worker-based approaches in other sectors.

Purpose of the Study:

  • To evaluate a leader-based safety intervention implemented at construction sites.
  • To enhance communication and safety interactions among management, clients, and coworkers.
  • To investigate the intervention's impact on overall on-site safety levels.

Main Methods:

  • A group-randomised, double-blinded case study involving six Danish construction sites (three intervention, three control).
  • Continuous recruitment from January to June 2010, with each site investigated over 20 weeks.
  • Confirmatory statistical analysis and qualitative methods to assess safety communication and safety level index.

Main Results:

  • The intervention led to a significant increase in safety-related communication between management and coworkers.
  • A measurable improvement in the safety level index was observed at intervention sites.
  • Qualitative data indicated enhanced safety communication across all managerial levels, including client engagement.

Conclusions:

  • The leader-based safety intervention effectively improved communication and safety outcomes in the construction industry.
  • Encouraging safety feedback from coordinators to management and clients is a viable strategy.
  • This approach holds promise for reducing construction site injuries through enhanced safety culture.
