Section 3 - Hazards Identification
Emergency Overview
Appearance: Light tan solution
Danger! Corrosive. Causes severe skin burns and serious eye damage. Causes respiratory and
gastrointestinal tract burns. May cause liver and kidney damage. May cause allergic skin reaction.
May cause methemoglobinemia. Vapor and liquid are harmful. May be fatal if inhaled or
swallowed. Corrosive to metal. Strong inorganic acid mists containing sulfuric acid may cause
cancer.
Target Organs: Eyes, skin, respiratory tract, liver, kidneys, teeth, central nervous system, red blood
cells, bladder
Potential Health Effects
Eye:
Causes severe eye burns. May cause irreversible eye injury. May cause blindness. May cause
permanent corneal opacification. The severity of injury depends on the concentration of the solution
and the duration of exposure.

Material Safety Data Sheet
Diphenylamine, 0.3% Aqueous
Skin:
Causes skin burns. The severity of injury depends on the concentration of the solution and the
duration of exposure.
Ingestion:
May cause severe and permanent damage to the digestive tract. Causes gastrointestinal tract burns.
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.
Inhalation:
May cause irritation of the respiratory tract with burning pain in the nose and throat, coughing,
wheezing, shortness of breath and pulmonary edema. Causes chemical burns to the respiratory tract.
Inhalation may be fatal as a result of spasm, inflammation, edema of the larynx and bronchi,
chemical pneumonitis and pulmonary edema. Exposure may impair lung function and cause
mucostasis (reduced mucous clearance). May cause methemoglobinemia, cyanosis (bluish
discoloration of skin due to deficient oxygenation of the blood), convulsions, tachycardia, dyspnea
(labored breathing), and death. May cause adverse central nervous system effects including
headache, convulsions, and possible death. May cause bladder injury and hypertension.
Chronic:
Prolonged or repeated skin contact may cause dermatitis. Prolonged or repeated inhalation may
cause nosebleeds, nasal congestion, erosion of the teeth, perforation of the nasal septum, chest pain
and bronchitis. Prolonged or repeated eye contact may cause conjunctivitis. Effects may be delayed.
Workers chronically exposed to sulfuric acid mists may show various lesions of the skin,
tracheobronchitis, stomatitis, conjunctivitis, or gastritis. Occupational exposure to strong inorganic
acid mists containing sulfuric acid is carcinogenic to humans. Adverse reproductive effects have
been reported in animals.
Section 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 at once. Do NOT allow victim to rub or keep eyes closed.
Skin:
Flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and
shoes. Get medical aid at once. Wash clothing before reuse.
Ingestion:
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 at
once.
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:
Monitor arterial blood gases, chest x-ray, and pulmonary function tests if respiratory tract irritation
or respiratory depression is evident. Treat dermal irritation or burns with standard topical therapy.
Effects may be delayed. Do NOT use sodium bicarbonate in an attempt to neutralize the acid.
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.

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. Use water spray to keep fire-exposed containers
cool. Substance is noncombustible. Contact with water can cause liberation of heat and splattering
of the material. Contact with metals may evolve flammable hydrogen gas. Runoff from fire control
or dilution water may cause pollution. Approach fire from upwind to avoid hazardous vapors and
toxic decomposition products. Oxides of sulfur may be produced in fire.
Extinguishing Media:
For small fires, use dry chemical, carbon dioxide, water spray or alcohol-resistant foam. Do not use
water if it can enter the containers because it can generate heat and possible spatter chemical over a
wider area.
Autoignition Temperature:
Not available.
Flash Point:
Not applicable.
NFPA Rating:
CAS# 7732-18-5: Health- 0, Flammability- 0, Instability- 0.
CAS# 7664-93-9: Health- 3, Flammability- 0, Instability- 2.
CAS# 122-39-4: Health- 2, Flammability- 1, Instability- 0.
Explosion Limits:
Lower: n/a Upper: n/a
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 that lead to waterways. Clean up spills immediately,
observing precautions in the Protective Equipment section. Carefully scoop up and place into
appropriate container labeled for disposal. Provide ventilation. Do not get water inside containers.
Section 7 - Handling and Storage
Handling:
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Do not
allow water to get into the container because of violent reaction. Do not get in eyes, on skin, or on
clothing. Keep container tightly closed. Discard contaminated shoes. Use only with adequate
ventilation. Do not breathe spray or mist. Do not use with metal spatula or other metal items. Inform
laundry personnel of contaminant's hazards.
Storage:
Do not store near combustible materials. Keep container closed when not in use. Store in a cool, dry,
well-ventilated area away from incompatible substances. Do not store near alkaline substances.
Store protected from light. Keep from contact with oxidizing materials.
