For hazardous waste containers, it is essential that they need to be kept closed except when being filled or emptied. This requirement is in place to prevent the release of hazardous materials into the environment, which can pose risks to human health and safety, as well as to the ecosystem. Keeping the containers closed minimizes the chances of spills, leaks, and exposure to harmful substances. In contrast, labeling with expiration dates is not a standard requirement for hazardous waste containers. While proper labeling is crucial, it typically includes information about the contents and associated hazards rather than an expiration date. Clear plastic containers may not provide the necessary chemical resistance required for many hazardous materials, and leaving containers open for ventilation can lead to significant hazards, including increased risk of fire, toxic exposure, and environmental contamination. Therefore, maintaining closed containers is a key practice in the management of hazardous waste.
