Final answer:
Sanding body filler and paint produces harmful fumes that can be inhaled and have negative health effects.
Step-by-step explanation:
Sanding body filler and paint produces harmful fumes. When surface materials such as body filler and paint are sanded, tiny particles become airborne and can be inhaled. These particles can contain toxic substances, such as heavy metals or chemicals, which can be harmful to the respiratory system.
For example, sanding body filler releases particles that may contain toxic chemicals like isocyanates, which can cause breathing difficulties and lung damage if inhaled. Similarly, sanding paint can release harmful solvents into the air, such as toluene or xylene, which can also have negative health effects when inhaled.
