Where should hazardous waste be stored until disposal?

Hazardous waste must be stored in a locked place to ensure safety and compliance with regulations. This practice helps prevent unauthorized access and minimizes the risk of theft, spillage, or other incidents that could jeopardize public health and the environment. A secure storage area reduces the likelihood of accidents, potential contamination, or exposure to hazardous substances.

Storing hazardous waste in a locked area also aligns with best practices and legal requirements for waste management, ensuring that it is kept safe until it can be disposed of properly. Proper storage protocols are essential for maintaining a safe work environment and for the management of hazardous materials in accordance with state and federal regulations.

The other options do not ensure the safety and security of hazardous waste. For instance, unmarked containers can lead to confusion and mishandling, while using any available space lacks organization and increases the risk of accidental exposure. Storing waste outside the worksite can expose it to the elements and unauthorized individuals, creating further hazards.
