Chemical Hazard Symbols and Safety Data Sheets (SDS)

Vocabulary flashcards covering NFPA hazard symbols, SDS contents, chemical labels, and storage/spill procedures.

NFPA hazard symbols

A rating system using color-coded diamonds to indicate health, flammability, and reactivity hazards of a chemical; ratings run from 0 (least dangerous) to 4 (most dangerous).

Chemical labels

Labels on chemical containers that convey hazard information and required precautions (including NFPA ratings).

SDS (Safety Data Sheet)

A detailed document for each chemical with identity, hazards, ingredients, physical properties, PPE, spill response, and storage info.

Name and trade name

The official chemical name and any commercial/trade name used for the substance.

Hazardous ingredients

Substances within a chemical that contribute to its hazards or toxicity.

Physical characteristics

Properties such as appearance, odor, state, melting/boiling points, and other physical properties.

Protective equipment

Personal protective equipment required when handling the chemical (gloves, goggles, lab coat, respirator, etc.).

Spill or leak response

Procedures to follow if a chemical is leaked or spilled, including containment and cleanup steps.

Storage guidelines

Instructions on safe storage, including temperature, segregation, compatibility, and ventilation.

Hazard rating scale (0-4)

The numerical scale on labels indicating danger level, where 0 is least dangerous and 4 is most dangerous.
