Why are floor drains prohibited in chemical storage areas?

Floor drains are prohibited in chemical storage areas primarily due to the risk of spills. When chemicals are stored, any accidental leaks or spills could lead to hazardous substances being washed away through floor drains, potentially contaminating the wastewater system, soil, and nearby water bodies. Regulations and best practices in environmental compliance aim to prevent such scenarios because handling and disposing of such contaminated water can be complex and costly.

The prohibition helps to ensure that any chemicals that do spill can be managed on-site without the risk of them entering the drainage system, thereby reducing environmental risks and promoting safety. This approach aligns with the broader goals of environmental protection and sustainability, as well as adherence to legal requirements concerning hazardous waste management.
