Noise Protection at Welding and Grinding Workstations
Noise protection at welding and grinding workstations includes measures to reduce or shield harmful sound levels caused by gouging, grinding, or arc noise. This includes providing hearing protection.
Physico-Chemical Mechanism of Action
Sound levels above 85 dB can damage hearing after prolonged exposure. The arc and mechanical noises like those from gouging or grinding generate strong sound waves.
Metallurgical Relevance & Risks in Welding
Hearing damage can lead to incapacity for work. Moreover, constant noise exposure can affect the productivity and well-being of workers.
Workshop Practice & Instructions
• Use sound shielding devices such as noise barriers or acoustic boxes to protect the workplace.
• Provide hearing protection items like earmuffs or earplugs and encourage workers to use them.
• Regularly check the effectiveness of the noise protection and maintain the acoustic absorbers.
