Dear Dr. Lia:
This is in response to your e-mail requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) regarding applicability to aqueous solutions of silver nitrate and iron sulfate. Specifically, you ask us to confirm that an aqueous solution of 0.25 % silver nitrate (0.015 M) and an aqueous solution of 0.25 % iron sulfate (0.008 M) in containers not more than 100 milliliters each do not meet the criteria for a hazardous material under the HMR.
Your understanding is correct. The concentration of the quantity of material per inner container, as described in your e-mail, does not meet the criteria for a hazardous material under the HMR and, therefore, is not subject to the HMR.
I hope this information is helpful. Please contact this office if you have additional questions.
Sincerely,
Hattie L. Mitchell
