Why can sanding be dangerous?

Sanding can be dangerous primarily due to the inhalation of fine dust particles, which can lead to respiratory issues and long-term lung damage. Additionally, the process generates heat and can create sparks, posing a fire hazard, especially when working with flammable materials. Improper use of sanding equipment can also result in physical injuries, such as cuts or abrasions. Wearing appropriate protective gear is essential to mitigate these risks.
