Certified Hazardous Materials Manager (CHMM) Practice Exam

The requirement that the label must have a date indicating when the waste was generated is critical for effective waste management. This information helps ensure that the hazardous waste is managed properly in accordance with regulatory timelines. Once waste is generated, it is subject to specific storage and disposal regulations that often depend on how long it has been in storage, which is why dating the container is essential. This practice not only aids in compliance with regulations but also assists in tracking waste and ensuring that it does not exceed allowable storage times.

In contrast, the other options may pertain to safe practices in hazardous material management but do not represent universal labeling requirements for hazardous waste containers. Indicating hazard level is important for safety but not a strict labeling requisite in all regulations, mentioning the weight is not standard for waste labels, and while container materials may be relevant for safety, they are not a labeling requirement either.
