3) Hazards Identification
EMERGENCY OVERVIEW
Appearance: clear light yellow green. Corrosive. Danger！Causes eye and skin burns。

Causes digestive and respiratory tract burns。

May cause methemoglobinemia。

Target Organs: Blood。

Potential Health Effects
Eye：May cause irreversible eye injury. Contact with liquid is corrosive to the eyes and causes severe burns.
Skin：Causes skin burns。

Ingestion: May cause methemoglobinemia，cyanosis （bluish discoloration of skin due to deficient oxygenation of the blood）, convulsions, and death。

Causes severe digestive tract burns with abdominal pain, vomiting，and possible death。

Methemoglobinemia is characterized by dizziness, drowsiness，headache, breath shortness，cyanosis with bluish skin，rapid heart rate and chocolate—brown colored blood。

Inhalation：Causes severe irritation of upper respiratory tract with coughing，burns, breathing difficulty, and possible coma。

May cause pulmonary edema and severe respiratory disturbances。

Chronic: Chronic inhalation and ingestion may cause effects similar to those of acute inhalation and ingestion.
4) First Aid Measures
Eyes：Flush eyes with plenty of water for at least 15 minutes，occasionally lifting the upper and lower eyelids。

Get medical aid immediately. Do NOT allow victim to rub or keep eyes closed。

Skin: Get medical aid immediately. Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes。

Discard contaminated clothing in a manner which limits further exposure。

Ingestion: Do NOT induce vomiting. If victim is conscious and alert，give 2—4 cupfuls of milk or water. Never give anything by mouth to an unconscious person。

Get medical aid immediately.
Inhalation：Remove from exposure to fresh air immediately。

If breathing is difficult，give oxygen。

Get medical aid. Do NOT use mouth—to-mouth resuscitation. If breathing has ceased apply artificial respiration using oxygen and a suitable mechanical device such as a bag and a mask.
Notes to Physician：Treat symptomatically and supportively.
5) Fire Fighting Measures
General Information：As in any fire，wear a self-contained breathing apparatus in pressure—demand，MSHA/NIOSH （approved or equivalent), and full protective gear。

Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated。

Extinguishing Media: Do NOT get water inside containers。

For small fires，use dry chemical，carbon dioxide, or water spray。

For large fires, use dry chemical, carbon dioxide, alcohol-resistant foam, or water spray. Cool containers with flooding quantities of water until well after fire is out.
6) Accidental Release Measures
General Information: Use proper personal protective equipment as indicated in Section 8。

Spills/Leaks:Remove all sources of ignition。

Absorb spill using an absorbent，non-combustible material such as earth，sand, or vermiculite。

7) Handling and Storage
Handling：Wash thoroughly after handling。

Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Do not get in eyes, on skin, or on clothing. Do not ingest or inhale. Discard contaminated shoes.
Storage: Store in a tightly closed container. Store in a cool，dry, well—ventilated area away from incompatible substances.
