Noise Risk Bowtie Analysis
The industry Noise Bowtie is a structured risk management tool designed to systematically address the contributing factors and controls for noise risk in the South African mining industry.
It visually maps the sequence from the key unwanted event, such as noise generated from operating mine equipment, through key hazards such as NIHL, and highlights the critical control measures required, including engineering controls.
On the right side, the bowtie outlines recovery and mitigation controls such as hearing protection and medical surveillance, which minimise the impact of noise exposure. This framework assists mines in identifying gaps, strengthening controls and driving systematic improvements in noise control practices.
Overall, the industry Noise Bowtie serves as an essential visual and operational guide, supporting mine personnel in creating a quieter work environment and advancing progress toward Zero Harm across the industry.
