What does a 3 in the blue triangle section of the NFPA label indicate?

A rating of 3 in the blue triangle section of the NFPA (National Fire Protection Association) label indicates a moderate health hazard. The NFPA label utilizes a color-coded system and a scale from 0 to 4, where 0 indicates no hazard and 4 indicates a severe hazard. A score of 3 reflects a situation where exposure to the substance could cause significant health effects, such as serious injury or illness, if proper precautions are not taken. This typically requires the use of appropriate personal protective equipment (PPE) to ensure safety while handling the material. Understanding this scale is crucial for professionals in the biomedical field, as it informs them of the potential risks associated with hazardous materials they may encounter.
