**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Irritating to eyes, respiratory system and skin.Stench.
Potential Health Effects
Eye:
Causes eye irritation. May cause chemical conjunctivitis.
Skin:
Causes skin irritation.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea. The toxicological properties of this substance have not
been fully investigated. Methemoglobinemia is characterized by
dizziness, drowsiness, headache, shortness of breath, cyanosis
(bluish discoloration of skin due to deficient oxygenation of the
blood), rapid heart rate and chocolate-brown colored blood.
Overexposure may cause methemoglobinemia. Mercaptans may cause
nausea and headache. Exposure to high concentrations of mercaptans
can produce unconsciousness with cyanosis (bluish discoloration of
skin due to deficient oxygenation of the blood), cold extremities and
rapid pulse.
Inhalation:
Causes respiratory tract irritation. The toxicological properties of
this substance have not been fully investigated. Methemoglobinemia is
characterized by dizziness, drowsiness, headache, shortness of
breath, cyanosis (bluish discoloration of skin due to deficient
oxygenation of the blood), rapid heart rate and chocolate-brown
blood. Exposure to high concentrations of mercaptans can produce
unconsciousness with cyanosis (bluish discoloration of skin due to
deficient oxygenation of the blood), cold extremities and rapid
pulse. Mercaptans may cause nausea and headache. Can produce delayed
pulmonary edema. Inhalation of aniline causes anoxia due to the
formation of methemoglobin.
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. Effects
may be delayed.
**** 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.
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:
Get medical aid. Do NOT induce vomiting. If conscious and alert,
rinse mouth and drink 2-4 cupfuls of milk or water.
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. 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. For methemoglobinemia,
administer oxygen alone or with Methylene Blue depending on the
methemoglobin concentration in the blood.
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. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion. Use water
spray to keep fire-exposed containers cool. Vapors may be heavier
than air. They can spread along the ground and collect in low or
confined areas. Containers may explode when heated.
Extinguishing Media:
Use agent most appropriate to extinguish fire. Cool containers with
flooding quantities of water until well after fire is out. Use water
spray, 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:
Avoid runoff into storm sewers and ditches which lead to waterways.
Clean up spills immediately, observing precautions in the Protective
Equipment section. Remove all sources of ignition. Absorb spill using
an absorbent, non-combustible material such as earth, sand, or
vermiculite. Do not use combustible materials such as sawdust.
Provide ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Avoid contact with eyes, skin, and
clothing. Keep container tightly closed. Keep away from heat, sparks
and flame. Avoid ingestion and inhalation. Use with adequate
ventilation. Use and store under nitrogen. Wash clothing before
reuse.
Storage:
Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances. Storage under
a nitrogen blanket has been recommended.
**** 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# 1783-81-9:
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.
