Which of the following is NOT an aspect of proper handling of hazardous substances?

Safely handling hazardous substances requires adherence to various safety protocols designed to minimize exposure and risk. Storing substances in easily accessible locations contradicts safe handling practices. Proper storage should prioritize safety and compliance with regulatory standards, which often means keeping hazardous substances in secure, designated areas that are not easily accessible to untrained personnel or the general public. This minimizes the risk of accidental exposure or misuse.

In contrast, wearing appropriate personal protective equipment is essential to shield individuals from exposure when handling hazardous materials. Correct disposal procedures are crucial to prevent environmental contamination and harm to human health, while accurate labeling ensures that everyone who encounters the substances is aware of the dangers and can take necessary precautions. Therefore, the correct answer highlights that improper storage directly compromises safety measures for hazardous substances.
