Step-by-step explanation:
The hmis or nfpa 704 hazardous material identification system rating for a slightly toxic chemical would be low health hazard (choice b).
The NFPA 704 system uses a diamond symbol to indicate the level of various hazards. The blue (left) diamond within the symbol represents the health hazard. The blue diamond is divided into four quadrants, each with a number ranging from 0 to 4. A rating of 0 indicates no health hazard, while a rating of 4 indicates an extreme health hazard. A slightly toxic chemical would have a low health hazard rating, typically between 1 and 2.
