Final answer:
It is true that some supplier labels for chemicals will not display a pictogram. Not all chemical products have hazards that meet the criteria for pictogram representation.
Step-by-step explanation:
The statement 'Some supplier labels will not display a pictogram' is true. Supplier labels must conform to the classification and labelling standards for hazardous chemicals, which are governed by regulations such as the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). Pictograms are visual representations of the hazards associated with a chemical product. However, not all hazards require a pictogram; some products may not pose a hazard significant enough to warrant one, or the hazard may be such that it does not fall under the specific criteria for pictogram representation. Therefore, a label might not display a pictogram if the chemical is not classified as hazardous by GHS criteria.
