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.

Environmental precautions
Environmental precautions

Methods and Equipment for Containment and Cleaning up:

Absorb spill with inert material （e.g, diatomaceous earth,sand） and flush spillage area with copious amounts of water.

Technical measures:

Wear proper protective equipment to avoid contact with skin or
inhalation of vapor.

Precautions for safe handling:Do not contact with metal powder, alkaline substances, or easyoxidized organic compounds.

:Store in a dark, cool place and tightly closed.

Aspiration hazard: Harmful if swallowed
rat LD50=805mg/kg (70% H2O2): Harmful in contact with skinrabbit LD50=690mg/kg (90% H2O2): No classification (gas)Harmful if inhaled: rat LC50=4108ppm/4h: mouse LC50=0.46-1.00mg/L/4h (90% H2O2): Causes severe skin burns
The conclusion with necrosis which penetrates to all layers of theskin or corrosivity is indicated in 3-minute, 1-hour, or 4-hourapplication on rabbits. Thus, it was classified into category 1B.
: Causes serious eye damage
The product is a skin corrosive substance. There is a publicationthat it shows severe irritation in animals and it is corrosive.
Based on the above information, it was classified into category 1.
: Classification not possible: Classification not possible: No classification
As for in vivo tests, there are negative data on micronucleus assay
in mouse bone marrow cells and chromosome adderration test in rat
bone marrow cells. As for in vitro tests, there are positive dataon riverse mutation test in bacteria, gene mutation examination in
cultuered mammalian cells, chromosome aberration test.
: Suspected of causing cancer
ACGIH classifies it as the group A3(confirmed animal carcinogenwith unknown relevance to humans).
: Classification not possible: Causes damage to organs (respiratory organs)
The irritations to the nose, the throat, and the tracheal arereported in humans and animals(rat, mouse). In animals(rat, mouse),
there are the descriptions that it causes the congestion,
pneumonedema, emphysema of lung and tracheal and necrosis of tractepithelium within the dosage (0.34-0.43 mg/L) of the guidance levelof category 1. Based on these results, it was classified into
category 1 (respiratory organs).
: Causes damage to organs (respiratory organs) through prolonged orrepeated exposure
In the inhalation test of vapor in dogs and rats, fibrous tissues
appear here and there in pneumoconiosis with the dosage (0.005-0.01mg/L) of guidance value range of category 1, and there was thestatement that mixture of atelectatic lung area and emphysema area(dogs), and necrosis and inflammation in nasal epithelium and cell
infiltration in larynx (rats) are seen and it has irritation in
nose, throat in humans and there is a risk of developing pulmonary
edema in the worst case. Thus, it was classified into category1(respiratory organs).
: Classification not possible
