GHS Hazard category ratings

GHS Hazard category ratings: Can some one please explain the rating on the chemicals in the SDS please? For example the Hydrochloric Acid 25 - 36% Hazard Identification : skin corrosion/irritation: category 1B, for Specific Target Organ Toxicity Single Exposure: category 3 and Corrosive to Metals: category 1.

Is the lower number less of a hazard or more of a hazard?
