Systems defects are failures in the design, implementation, or management of a system that can lead to accidents. Examples of systems defects include:
- Inadequate training of workers
- Lack of safety procedures
- Defective equipment
- Poor communication between workers
- Lack of maintenance or inspection of equipment
- Environmental factors that can lead to accidents, such as extreme weather or hazardous materials
Human error is not considered a system defect because it is not a failure of the system itself. Human error refers to the actions of an individual that can lead to an accident, such as:
- Making a mistake
- Not following safety procedures
- Being distracted
- Being fatigued
- Being under the influence of drugs or alcohol
While human error can be a contributing factor to an accident, it is not considered a system defect.
