Section 3 - Hazards Identification
Appearance: yellow crystals.
Warning! Harmful if swallowed. May cause severe
eye irritation and possible injury. May cause severe skin
irritation. Methemoglobin formation is the prinicipal cause of
toxicity. May cause liver and kidney damage. May cause reproductive
and fetal effects.
Target Organs: Blood, kidneys, liver, male
Potential Health Effects
Causes severe eye irritation. May cause eye injury. Effects may
Absorption into the body may cause cyanosis (bluish discoloration of
skin due to deficient oxygenation of the blood).
Harmful if swallowed. Causes gastrointestinal irritation with
nausea, vomiting and diarrhea. May cause systemic toxicity with
acidosis. May cause liver and kidney damage.
May cause cyanosis.
Causes respiratory tract irritation. May cause effects similar to
those described for ingestion.
Adverse reproductive effects have been reported in animals. Chronic
exposures of workers to dinitrobenzene have caused anemia; liver
injury has been reported in a few cases. Visual impairment has
occurred in the form of reduced visual acuity and central scotomas
(loss or depression of vision within the central visual field),
particularly for red and green colors. A yellow discoloration of the
conjunctiva and the sclera was a common observation in these
exposures (ACGIH Documentation of the TLV).
Section 4 - First Aid Measures
Immediately flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid imme
Get medical aid immediately. Immediately flush skin with plenty of
water for at least 15 minutes while removing contaminated clothing
Call a poison control center. If swallowed, do not induce vomiting
unless directed to do so by medical personnel. Never give anything by
mouth to an unconscious person. Get medical aid.
Get medical aid immediately. Remove from exposure and move to fresh
air immediately. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen.
Notes to Physician:
Treat symptomatically and supportively.
Section 5 - Fire Fighting Measures
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 foam, dry chemical, or carbon dioxide.

(estimated) Health: 2; Flammability: 1; Instability: 0
Section 6 - Accidental Release Measures
General Information: Use proper personal protective equipment as indicated
in Section 8.
Vacuum or sweep up material and place into a suitable disposal
container. Reduce airborne dust and prevent scattering by moistening
with water. Clean up spills immediately, observing precautions in
the Protective Equipment section.
Section 7 - Handling and Storage
Wash thoroughly after handling. Wash thoroughly after handling.
Remove contaminated clothing and wash before reuse. Use only in a
well-ventilated area. Avoid contact with skin and eyes. Avoid
ingestion and inhalation.
Store in a cool, dry place. Store in a tightly closed container.
Section 8 - Exposure Controls, Personal Protection
Use adequate general or local exhaust ventilation to keep airborne
concentrations below the permissible exposure limits.

Wear appropriate protective gloves to prevent skin
Wear appropriate protective clothing to prevent skin
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.
