**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Harmful if swallowed. Explosive when mixed with combustible
material.
Potential Health Effects
Eye:
Causes eye irritation. May cause conjunctivitis. May cause
permanent corneal opacification.
Skin:
Causes skin irritation. May cause severe irritation and possible
burns.
Ingestion:
Causes gastrointestinal irritation with nausea, vomiting and
diarrhea. May be harmful if swallowed. May cause burns to the
gastrointestinal tract. May cause systemic effects by ingestion:
blood hemolysis with or without anemia,
methemoglobinemia-carboxyhemoglobinemia, and pulmonary changes. May
cause damage to the red blood cells. May cause nausea, vomiting, and
diarrhea, possibly with blood.
Inhalation:
Causes respiratory tract irritation. May cause acute pulmonary
edema, asphyxia, chemical pneumonitis, and upper airway obstruction
caused by edema.
Chronic:
May cause methemoglobinemia, which is characterized by
chocolate-brown colored blood, headache, weakness, dizziness, breath
shortness, cyanosis (bluish skin due to deficient oxygenation of
blood), rapid heart rate, unconsciousness and possible death.
Laboratory experiments have resulted in mutagenic effects. May cause
kidney damage.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
Immediately flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid
immediately.
Skin:
Get medical aid. Flush skin with plenty of water for at least 15
minutes while removing contaminated clothing and shoes. Wash clothing
before reuse.
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 and move to fresh air immediately. If not
breathing, give artificial respiration. If breathing is difficult,
give oxygen. Get medical aid.
Notes to Physician:
For methemoglobinemia, administer oxygen alone or with Methylene
Blue depending on the methemoglobin concentration in the blood.
Antidote:
Do not use oils, greases or protective cream on skin. Do NOT use
oils or ointments in eye.
**** SECTION 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. Strong oxidizer. Contact with other material may
cause fire. Use water with caution and in flooding amounts. May
accelerate burning if involved in a fire.
Extinguishing Media:
Contact professional fire-fighters immediately. Cool containers with
flooding quantities of water until well after fire is out. Use water
fog only.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Vacuum or sweep up material and place into a suitable disposal
container. Clean up spills immediately, observing precautions in the
Protective Equipment section. Avoid generating dusty conditions.
Remove all sources of ignition. Do not use combustible materials such
as paper towels to clean up spill. Keep combustibles (wood, paper,
oil, etc.,) away from spilled material.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Use only in a well-ventilated area.
Minimize dust generation and accumulation. Avoid contact with eyes,
skin, and clothing. Keep container tightly closed. Avoid contact
with clothing and other combustible materials. Avoid ingestion and
inhalation.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of
ignition. Do not store near combustible materials. Store in a
tightly closed container. Store in a cool, dry, well-ventilated area
away from incompatible substances. Keep away from reducing agents.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate
ventilation to keep airborne concentrations low.
Exposure Limits
CAS# 7775-09-9:
Russia: 5 mg/m3 TWA
Personal Protective Equipment
Eyes:
Wear appropriate protective eyeglasses or chemical
safety goggles as described by OSHA's eye and face
protection regulations in 29 CFR 1910.133 or European
Standard EN166.
Skin:
Wear appropriate protective gloves to prevent skin
exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
A respiratory protection program that meets OSHA's 29
CFR 1910.134 and ANSI Z88.2 requirements or European
Standard EN 149 must be followed whenever workplace
conditions warrant respirator use.
