What is the primary hazard associated with pneumatics over hydraulics?

The primary hazard associated with pneumatics compared to hydraulics is excessive noise. Pneumatic systems often operate using compressed air, which can create significant noise levels during operation. This noise can be a health hazard for workers, leading to hearing loss and reduced concentration, as well as general discomfort in the workplace.

In contrast, hydraulic systems operate with fluids that can be quieter and less noisy than air, making them less likely to contribute to noise-induced issues. While other hazards like high pressure, electrical conductivity, and fire hazards exist in both systems, excessive noise is especially prominent in pneumatic systems, making it a key concern for safety and health in the workplace.
