Formula:
C6H5NO2
RTECS No:
DA6475000
Properties:
Very
flammable, light yellow-green to brown, oily liquid; solid below 42°F (6°C).
Pungent odor like bitter almonds or paste shoe polish. Some may not be able to
smell this substance. Sinks in water; insoluble. Vapors are heavier than air;
will collect in low areas. Combustion products include toxic nitrogen oxides.

HEALTH & SAFETY INFORMATION
• IDLH:
200
ppm/1,024 mg/m3
•
IARC:
Group 2B, possibly carcinogenic to humans
•
NTP:
Anticipated human carcinogen
• Odor threshold:
1.89 mg/m3 Odor is not a reliable indicator of the presence of
toxic amounts of vapor.
•
OSHA Table Z-1 Air Contaminant
•
Chemical protective clothing is recommended because vapor and liquid can be
dermally absorbed and may contribute to systemic toxicity. Irritating to skin,
eyes, nose and lungs. May interfere with the body's ability to use oxygen
(affects the blood cells, causing formation of methemoglobin). A blood and
nerve poison which is easily absorbed by the body. Exposure could cause
drowsiness and loss of consciousness; the effects may be delayed. Breathing
the
vapor, swallowing the material, or absorption through the skin can cause death.
Chronic exposure may affect the bone marrow and liver.
Exposure Limits:
•
ACGIH TLV:* 1 ppm TWA; BEI: 5 mg[total
p
nitrophenol]/g creatinine in urine, end of
shift at end of workweek; 1.5% methemoglobin in blood, end of shift. Confirmed
animal carcinogen with unknown relevance to humans. (skin)
•
OSHA PEL/NIOSH REL:* 1 ppm/5 mg/m3 TWA (skin)
•

Respirator:
At
any concentrations above the NIOSH REL, or where there is no REL, at any
detectable concentration:
SCBAF:PD,PP
(any self-contained breathing apparatus that has a full facepiece and is
operated in a pressure-demand or other positivepressure mode) SAF:PD,PP:ASCBA (any
suppliedair respirator that has a full facepiece and is operated in a
pressure-demand or other positive-pressure mode in combination with an
auxiliary self-contained breathing apparatus operated in a pressure-demand or
other positive-pressure mode).
Escape:
GMFOV
[any airpurifying, full-facepiece respirator (gas mask) with a chin-style,
front-or back-,mounted organic vapor canister] SCBAE (any appropriate
escape-type, selfcontained breathing apparatus).
Reactivity:
Forms
explosive mixture with air. Incompatible with nitric acid, nitrogen tetroxide,
caustics, ammonia, amines, phosphorus pentachloride, and chemically active
metals such as tin or zinc. Attacks some plastics, rubber, and coatings.
FIRE INFORMATION:
Fire fighting gear, including SCBA, does not provide adequate
protection. If exposure occurs, remove and isolate gear immediately and
thoroughly decontaminate personnel. If material or contaminated runoff enters
waterways, notify downstream users of potentially contaminated water.

FIRST AID:
Move
victim to fresh air. Call emergency medical care. Apply artificial respiration
if victim is not breathing. Do not use mouth-to-mouth method if victim ingested
or inhaled the substance; induce artificial respiration with the aid of a
pocket mask equipped with a one–way valve or other proper respiratory medical
device. Administer oxygen if breathing is difficult. Remove and isolate
contaminated clothing and shoes. In case of contact with substance, immediately
flush skin or eyes with running water for at least 20 minutes. For minor skin
contact, avoid spreading material on unaffected skin. Keep victim warm and
quiet. Effects of exposure (inhalation, ingestion, or skin contact) may be
delayed. Ensure that medical personnel are aware of the material(s) involved,
and take precautions to protect themselves.
