1. Statistical study of occupational accidents

In order to establish a new methodology for safety management in the workplace, a statistical approach has been applied to realize practical techniques, such as the prediction of time intervals of accident occurrence. Experiment name Statistical analysis of occupational accidents. Click on the image to view a larger version.

2. Promotion of safety culture

In order to promote safety culture in a company to prevent labor accidents caused by human factors, new policy and method of safety management are developing. Data obtained by questionnaire and interview surveys are analyzed and factors that affect promotion of safety attitude, behavior of workers are extracted. Experiment name Group discussion on promotion of safety culture. Click on the image to view a larger version.

3. Improvement of fall protection devices

New fall protection devices, such as a full body harness safety belt, a two-lanyards safety belt and an air bag are being evaluated, and criteria and the test methods for these devices are being investigated. Experiment name Dynamic performance test of full body harness. Click on the image to view a larger version.

4. Study of communication error

Studies on communication are conducted in an effort to prevent accidents that are attributed to human error. Experiments with voice recorders and video cameras are conducted to analyze the way tasks are carried out. An emphasis is placed on how the task information is communicated to the workers. Experiment name Experiment of communication error on scaffolding. Click on the image to view a larger version.

5. Cognitive psychological study by means of simulations

Human errors and their mechanism are studied as they relate to cognition, judgment, and operations. The cognitive response such as eye-movements, reaction time, etc. are measured with the virtual reality simulation. The findings are used to analyze the behavior associated with the risk-taking and -avoidance, the safety education, training. Experiment name Excavator simulator.

6. Information technology and workplace safety

To prevent hazards in systems requiring the human-machine interface, such as those in production and construction systems, studies are conducted to identify hazards with the use of CCD cameras installed in the workplace. Experiment name Experiment for detection of human body by means of visual information. Click on the image to view a larger version.
