Paints, chemicals, and adhesives should be used in well-ventilated areas primarily to prevent respiratory problems from inhaling fumes. Many of these substances release volatile organic compounds (VOCs) and other harmful fumes that can cause respiratory irritation, headaches, dizziness, and other health issues. Proper ventilation helps dissipate these harmful vapors and ensures a safer working environment.
While good ventilation can also help speed up the drying process and reduce fire hazards, the most critical reason is to protect respiratory health.
