HAZMAT Technician Practice Exam

Question: 1 / 400

What indicator shows that a substance is a potential oxidizer?

A blue label with a flammable symbol

A yellow or orange label with an oxidizer symbol

The presence of a yellow or orange label with an oxidizer symbol is an established indicator that a substance is a potential oxidizer. Oxidizers are chemicals that can cause or enhance the combustion of other materials by providing additional oxygen or facilitating the reaction that generates heat and flames. The yellow or orange color coding specifically signals a warning about the reactive nature of these substances, making it crucial for individuals handling or working near them to recognize the risk associated with their potential to support combustion.

This labeling system is designed to ensure that hazardous materials are correctly identified and handled with appropriate caution, minimizing the risk of fire or explosion. The oxidizer symbol further reinforces this classification, making it clear that these materials must be treated as significant dangers in a variety of environments.
