Verified step by step guidance1
Understand that the Hazard Communication Standard (HazCom) is designed to ensure that information about chemical hazards and protective measures is clearly communicated to users through labels and safety data sheets.
Identify the key elements required on chemical labels according to HazCom, which include information that helps users recognize the chemical and understand its hazards and safe handling procedures.
Recall that the essential components on a HazCom label are: the product identifier (name of the chemical), a signal word (such as 'Danger' or 'Warning'), hazard statements describing the nature and degree of the hazard, pictograms (symbols representing the hazard), supplier information (name and contact details), and precautionary statements (instructions to minimize or prevent adverse effects).
Recognize that other options like expiration date, batch number, storage temperature, or only chemical formula and manufacturer's logo do not fulfill the HazCom labeling requirements.
Conclude that the correct label must include product identifier, signal word, hazard statement, pictogram, supplier information, and precautionary statements to comply with HazCom.
