Question

I found the following MSDS information on HCl in this website:

http://www.jtbaker.com/msds/englishhtml/h3880.htm

But I can't find the NFPA rating, the extinguisher and LD50. Anyone have a clue?

Answer 1

LD 50 in section 11:

oral rabbit LD50: 900 mg/kg (Hydrochloric acid conc)

NFPA from:

http://chemresponsetool.noaa.gov/chemica...

HEALTH = 3; FIRE = 0; REACTIVITY = 0

Answer 2

just go to this website

http://www.americanbio.com/MSDS_PDF/AB00...

you should see the nfpa rating in section 3

extinguisher in section 5

as for ld50 go to this website http://www.bu.edu/es/labsafety/ESMSDSs/M...

Inhalation, mouse: LC50 =1108 ppm/1H; I

nhalation, rat: LC50 =3124 ppm/1H;

Oral, rabbit: LD50 = 900 mg/kg.

Oral, rat: LD50 = >90 mL/kg.

Take note Ld50 changes with the conc. of HCl
