Aspiration hazard:

Causes severe skin burns
Studies have shown that the substance (liquid and vapor) causes
severe damage to human skin and even short-time exposure can cause
damage to the skin, and that applying 8％ solution to rabbits
caused necrosis. Based on the above information, the substance wasclassified into category 1B.
Causes serious eye damage
Studies have shown that the substance causes cornea damage,resulting in irreparable visual impairment and that nitric acidcauses severe chemical burns in human eyes, which may lead to lossof eyesight due to blepharophimosis, adhesion of eyelid andirreparable corneal opacity. And the substance is rated as category
1B in Skin corrosion/irritation. Thus, the substance was classified
into category 1.

Causes damage to organs (respiratory organs)
The substance has airway irritation. There is human evidence
including "in inhalation exposure, cough, headache, nausea, chest
pain, dyspnea, bronchoconstriction, respiratory depression andpulmonary edema were noted" and "in oral exposure, corrosive
necrosis of oral cavity, gullet and stomach, and pneumonia wereobserved." There is evidence from animal studies including "ininhalation exposure test in rats, extensive airway inflammation,rhinitis, bronchitis, pneumonia, and pulmonary edema were noted."
These symptoms were observed with the dose of the guidance value
range of category 1. The substance adversely affects respiratoryorgans and is classified into category 1 (respiratory organs).
Causes damage to organs (respiratory organs, teeth) throughprolonged or repeated exposureStudies have shown that in occupational inhalation exposure tonitric acid, 3 of 32 exposed workers suffered tooth germ erosion(no onset in 293 subjects of control group). Studies have also
described that in repeated exposure to nitric acid vapor and mist,
chronic bronchitis was noted, and in severe exposure cases,
chemical pneumonia as well as erosion of tooth germ, especiallycanine tooth and incisor were observed. Based on the above
information on human occupational exposure, the substance isclassified into category 1 (respiratory organs, teeth).
Classification not possible

12. Ecological information
Ecotoxicity
Aquatic acute
Aquatic chronic: Harmful to aquatic life
Gambusia affinis LC50=72mg/L/96h (as nitric acid): No classification
Nitric acid exists widely as natural substances, and fromresults of acute toxicity test on the salts, it is known thatdecreased pH causes acute toxicity. It is known to cause adverse
effects when concentrations of nitrate ions are high, but it isestimated that toxicity does not occur generally at aconcentration of 1 mg/L for classification in chronic toxicity.
Therefore, it was classified as "No classification."

13. Disposal considerations
Ecological waste information: Neutralization method :Add sodium carbonate solution or calcium hydroxide solution tothe mixed acid to neutralize. After neutralizing, flush in adrain with plenty of water. In case of using calcium hydroxidesolution, it creates precipitation. Filter the precipitation
and bury in a landfill site approved for hazardous waste
disposal.
Or entrust approved waste disposal companies with thedisposal.

Contaminated container andpackaging: In case of disposal of empty bottles, dispose bottles after
removing the content thoroughly.
