**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Harmful if swallowed. Irritating to eyes and skin. May cause
sensitization by skin contact. Very toxic to aquatic organisms.
Harmful : danger of serious damage to health by prolonged exposure if
swallowed.Moisture sensitive.Air sensitive.
Potential Health Effects
Eye:
Causes eye irritation and possible burns.
Skin:
Causes skin irritation. May cause skin sensitization, an allergic
reaction, which becomes evident upon re-exposure to this material.
May be absorbed through the skin. May cause skin burns.
Ingestion:
Harmful if swallowed. May cause severe gastrointestinal tract
irritation with nausea, vomiting and possible burns. May cause
methemoglobinemia, cyanosis (bluish discoloration of skin due to
deficient oxygenation of the blood), convulsions, and death.
Inhalation:
May cause methemoglobinemia, cyanosis (bluish discoloration of skin
due to deficient oxygenation of the blood), convulsions,
tachycardia, dyspnea (labored breathing), and death. May cause severe
irritation of the respiratory tract with sore throat, coughing,
shortness of breath and delayed lung edema.
Chronic:
May cause liver and kidney damage. Absorption into the body leads to
the formation of methemoglobin which in sufficient concentrations
causes cyanosis (bluish discoloration of skin due to deficient
oxygenation of the blood).
**** 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 immediately. Immediately flush skin with plenty of
water for at least 15 minutes while removing contaminated clothing
and shoes. Wash clothing before reuse. Destroy contaminated shoes.
Ingestion:
Do not induce vomiting. If victim is conscious and alert, give 2-4
cupfuls of milk or water. Get medical aid immediately.
Inhalation:
Remove from exposure and move 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:
Absorption of this product into the body may cause cyanosis (bluish
discoloration of skin due to deficient oxygenation of the blood).
Moderate degrees of cyanosis need to be treated only by supportive
measures: bed rest and oxygen inhalation. For methemoglobinemia,
administer oxygen alone or with Methylene Blue depending on the
methemoglobin concentration in the blood. Cleansing of the entire
contaminated area of the body is of utmost importance.
Antidote:
Methylene blue, alone or in combination with oxygen is indicated as
a treatment in nitrite induced methemoglobinemia.
**** 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. Exposure to heat may promote violent decomposition.
Use water spray to keep fire-exposed containers cool. Use
extinguishing media appropriate to the surrounding fire. May explode
if heated above 115C.
Extinguishing Media:
Use dry chemical, carbon dioxide, or appropriate foam.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Clean up spills immediately, observing precautions in the Protective
Equipment section. Wear a self contained breathing apparatus and
appropriate personal protection. (See Exposure Controls, Personal
Protection section). Sweep up, then place into a suitable container
for disposal. Avoid generating dusty conditions. Provide
ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Minimize dust generation and accumulation. Keep
container tightly closed. Do not get on skin or in eyes. Do not
ingest or inhale. Do not allow contact with water. Use only in a
chemical fume hood.
Storage:
Store in a cool, dry, well-ventilated area away from incompatible
substances. Corrosives area. Do not store above 65C.
**** 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# 5470-11-1:
Personal Protective Equipment
Eyes:
Wear chemical splash goggles.
Skin:
Wear appropriate protective gloves to prevent skin
exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
Follow the OSHA respirator regulations found in 29
CFR 1910.134 or European Standard EN 149. Use a
NIOSH/MSHA or European Standard EN 149 approved
respirator if exposure limits are exceeded or if
irritation or other symptoms are experienced.
