Which tool helps determine hazard severity?

Explanation:
GHS symbols provide a standardized way to communicate how dangerous a chemical is by using pictograms, signal words (such as Danger or Warning), and hazard statements on labels and safety data sheets. Each pictogram flags a hazard class—like flammable, toxic, or corrosive—and the accompanying statements convey the level of severity, allowing you to quickly assess and compare hazards across substances. This global, uniform system makes it the most effective tool for determining hazard severity. In contrast, NFPA ratings give a facility-specific quick snapshot, PEL values are exposure limits rather than intrinsic hazards, and LD50 is just a single toxicity measure that doesn’t cover all hazard classes or labeling.
