Accident; Analysis and Prevention
|August 16, 2014
Summary
This study used fault tree analysis to identify causes of fatal falls in Taiwan's construction industry. Understanding these causes improves construction safety and risk management.
Area of Science:
- Occupational Safety and Health
- Construction Engineering
- Risk Management
Background:
- Fatal falls remain a significant concern in the construction industry.
- Understanding the multifactorial causes of these accidents is crucial for effective prevention strategies.
Purpose of the Study:
- To apply fault tree analysis (FTA) to identify and represent causal relationships leading to fatal falls in the construction industry.
- To analyze data from 411 work-related fatalities in Taiwan's construction sector.
Main Methods:
- Fault Tree Analysis (FTA) was employed to map causal relationships.
- Boolean algebra and minimal cut set analyses were conducted.
- Data included age, gender, experience, falling site, falling height, company size, and up to three causes per fatality.
Main Results:
- The study identified key causal factors contributing to fall fatalities across different falling sites.
- Fault trees visually represented the basic events triggering fatal falls.
- Graphical fault trees were developed for enhanced communication.
Conclusions:
- Fault tree analysis provides a structured method for understanding construction fall fatalities.
- Graphical representations of fault trees facilitate inter-disciplinary risk management discussions.
- Improved communication of accident causation can enhance safety for frontline supervisors.

When analyzing a single line-to-ground fault from phase A to ground at a three-phase bus, it is important to consider the fault impedance. This impedance is zero for a bolted fault, equal to the arc impedance for an arcing fault, and represents the total fault impedance for a transmission-line insulator flashover. To derive sequence and phase currents, fault conditions are translated from the phase domain to the sequence domain.

508
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...

01:22Design Consideration
666
Designing a structure involves a series of considerations, primarily the material's ultimate strength, calculated through tests that measure changes under increased force until the material reaches its breaking point or limit. The ultimate load, where the material breaks, is divided by its original cross-sectional area, resulting in the ultimate normal stress or strength. The ultimate shearing stress is another significant factor taken into account.

Frames are essential components of various mechanical and structural systems used daily. These structures are known for their stability and ability to bear heavy loads. A frame is constructed using two-force and multi-force members, interconnected using pin joints. In contrast, trusses are made entirely of two-force members.
Frames are versatile and widely used in various applications such as structural supports for beams and columns, automobile chassis construction, and in the construction...

01:21Fatigue
1.1K
Fatigue occurs when materials rupture under repeated or fluctuating loads, even at stress levels far below their static breaking strength. It typically results in brittle failure, even for ductile materials. It is a critical consideration in designing machines and structural components subjected to repetitive or varying loads. The nature of these loadings can range from fluctuating loads like unbalanced pump impellers causing vibrations to repeatedly bending a thin steel rod wire back and forth...
