Final answer:
The company logo is not a required GHS element for conveying hazard information on SDS and labels. Hazard pictograms, signal words, and precautionary statements are mandatory GHS elements designed to communicate risks associated with chemicals.
Step-by-step explanation:
The Globally Harmonized System of Classification and Labelling of Chemicals (GHS) requires certain elements to be included on both the Safety Data Sheets (SDS) and labels to convey hazard information. The elements that are necessary include Hazard Pictograms, a Signal Word, and Precautionary Statements. These elements are crucial for communicating the hazards associated with chemical substances and mixtures. Therefore, Option 4: Company Logo is not a required element by GHS standards on SDS and labels. While it may be included for branding or identification purposes, it is not part of the standardized requirements designed to communicate hazard information.
