What practice is essential when handling chemicals?

Reading the label before use is essential when handling chemicals because it provides critical information regarding the substance, including its hazards, proper handling instructions, and any necessary precautions. Chemical labels typically include details such as the chemical name, concentration, hazard symbols, and first aid measures in case of exposure. This information is crucial for ensuring safety and preventing accidents or injuries.

Understanding the specific properties of the chemical and the recommended safety measures can help prevent harmful reactions, mitigate exposure risks, and ensure that the chemical is used in a manner consistent with regulatory standards. The practice of consulting and understanding the label is a fundamental safety protocol in laboratories and any environment where chemicals are handled, promoting awareness and responsible handling of potentially hazardous materials.
