Why should materials containing hazardous substances be identified?

Identifying materials containing hazardous substances is crucial for ensuring health and safety in any environment. Knowing which materials pose risks allows individuals and organizations to assess potential dangers to human health and the environment effectively. This identification process helps in implementing proper safety measures, such as appropriate handling procedures, protective equipment requirements, and emergency response protocols. Recognizing these hazardous materials helps to prevent accidents and exposure, ultimately promoting a safer workplace.

The other options do not fully address the primary rationale for identifying hazardous materials. While isolating these substances from regular cleaning supplies and working towards cost reduction are important considerations, they are secondary to the fundamental need to recognize and mitigate health and safety risks associated with hazardous substances.
