Which rating corresponds to R-1233zd in ASHRAE safety categories?

Explanation:
The rating system uses two attributes: toxicity (A or B) and flammability (numbers 1–3, with 1 meaning nonflammable). R-1233zd is classified as A1, which means it has low acute toxicity and is nonflammable. That combination indicates a relatively low health and fire hazard compared with other refrigerants, so A1 is the correct rating.
