OSHA Section 4 – Worker Rights Under OSHA Practice Test

Section 3 covers composition/information on ingredients. It lists the exact identity of the chemical, including the chemical name, any common names or synonyms, and identifiers such as the CAS number and other unique IDs. It also includes impurities and stabilizing additives that influence how the substance is classified hazard-wise. This makes it possible to accurately identify the substance and understand its classification and hazards. The other items point to different sections—handling and storage precautions are in Section 7, and personal protective equipment requirements are in Section 8—so they don’t belong in Section 3. The listed items in Section 3 are best captured by including the chemical identity, synonyms, identifiers, and any impurities or stabilizers that affect classification.
