In the Emergency Response Guidebook, what are the two types of potential hazards found in each guide?

• A. Spill and leak
• B. Reactivity and solubility
• C. Corrosive and flammable
• D. Health and fire

Answer: (D)

The guides in the Emergency Response Guidebook present two types of potential hazards: health hazards and fire hazards. Health hazards describe the toxic effects a material can have on people through exposure, whether by inhalation, ingestion, or skin contact. Fire hazards describe how easily the material can burn or contribute to a fire, including its flammability and ignition risk. This framing helps responders quickly decide on protective measures to prevent exposure and on actions to control and suppress a fire. The other options describe release scenarios or specific chemical properties, which aren’t the two hazard categories used in each guide.
