Verified step by step guidance1
Understand that standard laboratory safety pictograms are designed to communicate specific types of hazards present in a laboratory environment.
Recognize that these pictograms typically represent chemical hazards (such as flammability, toxicity, corrosiveness) and physical hazards (such as radiation, explosive materials, or compressed gases).
Note that biological hazards, electrical hazards, and ergonomic hazards are either represented by different symbols or are not the primary focus of the standard laboratory safety pictograms.
Recall that the Globally Harmonized System (GHS) of Classification and Labeling of Chemicals provides standardized pictograms mainly for chemical and physical hazards.
Conclude that the correct classification of hazards represented by these pictograms is 'Chemical and physical hazards.'
