Administration of oxygen may be needed. Remove contaminated clothes. Rinse and then wash skin with water and soap. See Notes. Refer immediately for medical attention.
In case of eye contact
Rinse with plenty of water (remove contact lenses if easily possible).
If swallowed
Administration of oxygen may be needed. Rinse mouth. Do NOT induce vomiting. Give one or two glasses of water to drink. Refer immediately for medical attention.
4.2 Most important symptoms/effects, acute and delayed
Exposure Routes: inhalation, skin absorption, ingestion, skin and/or eye contact Symptoms: Headache, dizziness; cyanosis; red blood cell Heinz bodies; [potential occupational carcinogen] Target Organs: Blood, kidneys, liver, cardiovascular system, central nervous system (NIOSH, 2016)
4.3 Indication of immediate medical attention and special treatment needed, if necessary
/SRP:/ Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Aniline and related compounds/
5.Fire-fighting measures
5.1 Extinguishing media
Suitable extinguishing media
Use dry chemical, carbon dioxide, or alcohol foam extinguishers. Vapors are heavier than air and will collect in low areas. Vapors may travel long distances to ignition sources and flashback. Vapors in confined areas may explode when exposed to fire. Storage containers and parts of containers may rocket great distances, in many directions. If material or contaminated runoff enters waterways, notify downstream users of potentially contaminated waters. Notify local health and fire officials and pollution control agencies. From a secure, explosion-proof location, use water spray to cool exposed containers. If cooling streams are ineffective (venting sound increases in volume and pitch, tank discolors or shows any signs of deforming), withdraw immediately to a secure position ... The only respirators recommended for fire fighting are self-contained breathing apparatuses that have full facepieces and are operated in a pressure-demand or other positive-pressure mode. /Anisidines/
5.2 Specific hazards arising from the chemical
This chemical is combustible.
5.3 Special protective actions for fire-fighters
Wear self-contained breathing apparatus for firefighting if necessary.
6.Accidental release measures
6.1 Personal precautions, protective equipment and emergency procedures
Use personal protective equipment. Avoid dust formation. Avoid breathing vapours, mist or gas. Ensure adequate ventilation. Evacuate personnel to safe areas. Avoid breathing dust. For personal protection see section 8.
6.2 Environmental precautions
Evacuate danger area! Consult an expert! Personal protection: chemical protection suit including self-contained breathing apparatus. Do NOT let this chemical enter the environment. Do NOT wash away into sewer. Collect leaking liquid in sealable containers. Absorb liquid in sand or inert absorbent. Then store and dispose of according to local regulations.
6.3 Methods and materials for containment and cleaning up
Spill handling: Evacuate persons not wearing protective equipment from area of spill or leak until clean-up is complete. Remove all ignition sources. Collect powdered material in the most convenient and safe manner and deposit in sealed containers. Ventilate area of spill or leak. Cover with sand and soda ash (9:1). After mixing, collect material in the most convenient and safe manner and deposit in sealed containers. Keep o-anisidine out of confined spaces, such as a sewer, because of the potential for an explosion, unless the sewer is designed to prevent the buildup of explosive concentrations. If material or contaminated runoff enters waterways, notify downstream users of potentially contaminated waters. It may be necessary to contain and dispose of this chemical as a hazardous waste. Contact your Department of Environmental Protection or your regional office of the federal EPA for specific recommendations. /Anisidines/
7.Handling and storage
7.1 Precautions for safe handling

Store only in original container. Keep in a well-ventilated room. Separated from strong oxidants, acids, chloroformates and food and feedstuffs. Store in an area without drain or sewer access. Provision to contain effluent from fire extinguishing.Store in tightly closed containers in a cool, well ventilated area. Protect against sunlight and strong oxidizers. Metal containers involving the transfer of this chemical should be grounded and bonded. Where possible, automatically pump liquid from drums or other storage containers to process containers. Drums must be equipped with self-closing valves, pressure vacuum bungs, and flame arresters. Use only nonsparking tools and equipment, especially when opening and closing containers of this chemical. Sources of ignition, such as smoking and open flames, are prohibited where this chemical is used, handled, or stored in a manner that could create a potential fire or explosion hazard. A regulated, marked area should be established where this chemical is handled, used, or stored ... /Anisidines/

12.2 Persistence and degradability
AEROBIC: o-Anisidine, present at 100 ppm, reached 81.7% theoretical BOD (NH3 end product) in two weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(1); it reached 40 to 69.1% of its theoretical BOD (NO2 end product) in 2 weeks using an activated sludge inoculum at 30 mg/L(1,2). At high concentrations, o-anisidine has been shown to be toxic to microorganisms and biodegrades at a much slower rate(3,4). 20 ug/L o-anisidine, inoculated with a mixed culture of soil microorganisms in an aqueous mineral salts medium, was found to persist >64 days as measured by UV absorbency(5). 2% of the theoretical BOD was achieved for o-anisidine at 20 ppm in sea water from Akashi Beach, Japan. These biodegradation data indicate that o-anisidine will biodegrade rapidly under aerobic conditions(SRC) except when microorganisms are killed by high concentrations of the compound(2,3).
12.3 Bioaccumulative potential
An estimated BCF of 2 was calculated in fish for o-anisidine(SRC), using a log Kow of 1.18(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
12.4 Mobility in soil
The Koc of o-anisidine is estimated as 46(SRC), using a log Kow of 1.18(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that o-anisidine is expected to have very high mobility in soil. The pKa of o-anisidine is 4.53(4), indicating that this compound will partially exist in the cation form in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(5). Anilines are expected to bind strongly to humus or organic matter in soils due to the high reactivity of the aromatic amino group(6,7).
12.5 Other adverse effects
no data available
13.Disposal considerations
