Personal Precautions, Protective Equipment and Emergency Procedures
General measures:

Wear proper protective equipment and avoid contact with skin andinhalation of vapor. Conduct operations from upwind and evacuate
people downwind. Keep away personnel except for authorized ones
from spillage area by stretching ropes.

:

Attention should be given to avoid discharge of spilled productinto rivers and resulting environmental damage. When diluting
spill with large amounts of water, discharge of untreatedwastewater into the environment must be avoided.

Aspiration hazard:

Causes severe skin burns
The result of applying 85% solution of this substance to therabbit, there is a report that the corrosion was observed within 4hours. On the other hand, result of the occlusion application of
75% solution of this substance for 4.5 hours, corrosion was notobserved. In addition, although more detailed information isunknown, there is the description that 75% solution causes severeburns to the skin. Based on the above results, it was classified
into category 1C.
Causes serious eye damage
Result of the application of this substance(75-85%) to the eyes ofrabbit, there is the description that corrosion was observed. Inaddition, this substance is classified into category 1C in the skincorrosion/irritation. Based on the results, it was classified into
category 1.
Classification not possible
Classification not possible
Classification not possible
There were no in vivo data. As for in vitro, it was negative inbacterial reverse mutation tests and a chromosomal aberration testwith cultured mammalian cells.
Classification not possible
Classification not possible
There is a report that in a combined repeated dose toxicity study
with the reproduction/developmental toxicity screening test withrats by the oral route (gavage) (OECD TG 422), neither reproductive
toxicity nor developmental toxicity was observed even at a dose
where parental toxicity (death in 2/13 females) was observed.
However, since it is a screening test, and information on
teratogenicity was lacking, it was classified as "Classification
not possible."Causes damage to organs (respiratory organs)
This substance is respiratory irritation to humans and experimental
animals. Although there were some cases in humans, inhalation
causes hoarseness, breathing difficulties, wheezing (by laryngealedema) by severe exposure. In the most serious case, may cause
noncardiogenic pulmonary edema. There is the report that nausea,vomiting, abdominal pain, bloody diarrhea, esophagus, irritation orburns of the stomach by oral administration. Based on the results,
it was classified into category 1 (respiratory organs).
Classification not possible
There were no hazardous findings in humans. As for experimental
animals, in a combined repeated dose toxicity study with thereproduction/developmental toxicity screening test in which rats
were administered this substance by gavage (male: 42 days, female:40-52 days), no toxicity was observed at up to 250 mg/kg/day, andalthough death was observed at 500 mg/kg/day, the target organ wasunknown. Thus, although it corresponded to "No classification" by
the oral route, there was no toxicity information by the otherroutes, therefore, classification was not possible due to lack ofdata.
Classification not possible

Aquatic chronic: Harmful to aquatic life
Oryzias latipes LC50=75.1mg/L/96h (Not pH adjusted) (asphosphoric acid): No classification
Because of 48-hour EC50 > 376 mg/L for crustacea (Daphnia magna)
in an acute immobilization test with pH adjustment, and since
phosphoric acid exists universally in an environment and is an
essential nutrient for living organisms, it was classified as "Noclassification."

13. Disposal considerations
Ecological waste information: Add alkali such as calcium hydroxide, sodium carbonate
gradually to neutralize and then flush in a drain with a large
amount of water. Or entrust approved waste disposal companies
with the disposal.

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