For which application is lead-based paint still acceptable?

Lead-based paint is still permissible for specific applications, particularly in certain industrial or commercial areas, such as painting bridges. This is primarily because the use of lead pigments in these high-risk and specialized settings can offer benefits such as improved durability and resistance to extreme weather conditions. However, strict guidelines and regulations are often applied to ensure safety during application and maintenance processes, as lead can pose serious health risks, especially in environments where exposure is likely.

In contrast, the other applications are more strictly regulated or outright prohibited because of the high potential for lead exposure. For instance, exterior house paints, painting toys, and furniture are all areas where the risk of lead exposure is significant, especially in residential or child-accessible environments. In these cases, the harmful effects of lead on human health, particularly for children, have led to greater caution and regulatory restrictions on its use.
