Human Errors in Relation with Human-Machine Interface and Occupational Safety and Health in Manufacturing Industry
Human errors in relation with Human-machine interface and Occupational Safety and health in Manufacturing Industry * Ramanathan Muthukaruppan
1. Introduction:
The use of complex machines and systems has been ever increasing in all sectors, especially in manufacturing sector. Most of the industries go for rapid upgrades in production technology to face the global competition. Particularly, manufacturing machines in metal industry is affected by increasing complexity and increase in use of complex machines and systems. In general, the working environment has become more complex in industrial processes. This expands beyond production section to monitoring and quality control sections of the industry as well. This results in increase in operators’ mental workload and consequently in increased risk of errors because the machine operators have to handle complex data and alarms and to take safety-critical decisions under the pressure of unexpected and rapidly changing hazardous situations. Thus HMI (Human Machine Interface) has gained greater significance in Occupational health and safety in terms of increasing accidents due to errors. Human errors because of complex HMI not only results in accidents but also serves as a source for increased mental strain and stress. This Literature review is focused on four main questions: * What are the aspects of HMI design that serve as direct source of human errors? * What is the impact of the human errors due to complex HMI in mental strain and stress of Machine workers in manufacturing industry? * What is the current state of research and development that focuses on reducing the human errors due to complex HMI in manufacturing industry? * What is the future direction of research and development on HMI design in relation to reducing human errors in workplace that leads to occupational injuries and illness? 2.
