Which of the following is NOT a safety hazard typically found in a workshop?

Excessive noise is often considered a nuisance rather than a direct safety hazard in many workshop settings compared to the other listed hazards. While prolonged exposure to high noise levels can lead to hearing loss and may impact worker well-being over time, it is not typically classified as an immediate safety hazard like flammable materials, which can cause fires, electricity issues that can result in shock or electrocution, or exposure to ultraviolet rays, which can lead to skin damage and eye injury.

In contrast, flammable materials directly pose a risk of fire and require proper storage and handling procedures to mitigate that risk. Exposure to electricity can lead to severe injuries or fatalities if proper safety measures are not in place, and ultraviolet rays from certain equipment can have harmful effects on skin and eyes, necessitating specific safety protocols in workshops where such exposure is likely. Thus, while noise is an important consideration for workplace health, it does not present an immediate hazardous scenario in the same way as the other options.
