What is the purpose of the sign 'wear a mask'?

Explanation:
Wearing a mask is about protecting the lungs from inhaling airborne hazards that come with painting and finishing tasks. When you spray paint, sand, or handle powders, tiny particles and fumes float in the air; a mask filters these so they don’t reach the airways, reducing the risk of breathing problems or irritation. It’s not about protecting eyes, which needs goggles, nor about reducing glare or keeping you warm. In some scenarios there might be sparks, but a mask’s purpose is specifically to prevent inhalation of particles and fumes.
