Final answer:
The statement regarding the introduction of four new GHS pictograms in the new WHMIS is false. WHMIS was updated in 2015 and there have been no new pictograms added since then.
Step-by-step explanation:
The statement that four new GHS pictograms are being introduced in new WHMIS is false. WHMIS, the Workplace Hazardous Materials Information System, was updated in 2015 to incorporate the Globally Harmonized System (GHS) for classifying and labeling chemicals. This updated system, known as WHMIS 2015, included new standardized pictograms for hazard communication. These pictograms are designed to be used internationally to convey specific information about the hazards of various chemicals. As of my knowledge cutoff date in 2023, no new pictograms have been introduced since the initial adoption of the GHS components into WHMIS.
