Why should an individual working with chemicals understand the hazard coding system on a chemical label?

Explanation:

The hazard coding system (developed by the National Fire Protection Association, NFPA) helps the individual working with chemicals to know which chemical is a health hazard, inflammable hazard or a reactivity hazard. This makes the individual makes informed decisions while handling such chemicals and also assists the individual or first responders to know what to or not to do in emergency cases or accident (like contact with the skin).

NOTE: The colour code used here have the meanings below

Red: flammability/fire hazard

Blue: health hazard

Yellow: reactivity hazard

White: special hazard

in theory, limestone is composed principally of the compound calcium carbonate - caco3, but in reality this compound is deposited in conditions involving a number of other compounds as impurities so it ends up being a mixture of many compounds.
