Most important symptoms/effects, acute and delayed
SYMPTOMS: Symptoms of exposure to this compound include eye irritation with possible corneal injury (necrosis); paleness, cyanosis, weakness, sweating, headache, diarrhea, nausea, vomiting, diarrhea, dizziness, fainting, dark urine, central nervous system depression, and deoxyribonuclease inhibition. Chronic exposure may include irritation and lesions of the respiratory system. ACUTE/CHRONIC HAZARDS: This chemical is a skin and eye irritant. Corneal damage is possible upon eye contact. First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop. (NTP, 1992)
Indication of immediate medical attention and special treatment needed, if necessary
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. Phenols and related compounds
SECTION 5: Firefighting measures

Environmental precautions
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into sealable containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.
Methods and materials for containment and cleaning up
SRP: Wastewater from contaminant suppression, cleaning of protective clothing/equipment, or contaminated sites should be contained and evaluated for subject chemical or decomposition product concentrations. Concentrations shall be lower than applicable environmental discharge or disposal criteria. Alternatively, pretreatment and/or discharge to a permitted wastewater treatment facility is acceptable only after review by the governing authority and assurance that "pass through" violations will not occur. Due consideration shall be given to remediation worker exposure (inhalation, dermal and ingestion) as well as fate during treatment, transfer and disposal. If it is not practicable to manage the chemical in this fashion, it must be evaluated in accordance with EPA 40 CFR Part 261, specifically Subpart B, in order to determine the appropriate local, state and federal requirements for disposal.
SECTION 7: Handling and storage
Precautions for safe handling
NO open flames. Prevent deposition of dust. Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
Conditions for safe storage, including any incompatibilities
Separated from strong oxidants, strong bases and food and feedstuffs. Store only in original container. Provision to contain effluent from fire extinguishing. Store in an area without drain or sewer access.Store in tightly closed containers in a cool, well-ventilated area away from water. Sources of ignition, such as smoking and open flames, are prohibited where o-phenylphenol is used, handled, or stored in a manner that could create a potential fire or explosion hazard.

SECTION 10: Stability and reactivity
Reactivity
Reacts with strong bases and strong oxidants. Decomposes on heating. This produces carbon dioxide, carbon monoxide and irritating fumes.
Chemical stability
Stable at normal conditions.
Possibility of hazardous reactions
This chemical is a combustible solid.Dust explosion possible if in powder or granular form, mixed with air.2-PHENYLPHENOL react as a weak organic acid. Exothermically neutralizes bases. May react with strong reducing substances such as hydrides, nitrides, alkali metals, and sulfides to generate flammable gas (H2) and the heat of the reaction may ignite the gas. Is sulfonated very readily (for example, by concentrated sulfuric acid at room temperature) in exothermic reactions. May be nitrated very rapidly. Nitrated phenols often explode when heated and also form metal salts that tend toward detonation by rather mild shock. Can react with oxidizing agents (NTP, 1992).
Conditions to avoid
no data available
Incompatible materials
Strong oxidizers, acids, alkalis.
Hazardous decomposition products
When heated to decomposition it emits acrid smoke and irritating fumes.

SECTION 12: Ecological information
Toxicity
- Toxicity to fish: LC50 - Danio rerio (previous name: Brachydanio rerio) - 4.5 mg/L - 96 h.
- Toxicity to daphnia and other aquatic invertebrates: NOEC - Daphnia magna - 0.78 mg/L - 48 h.
- Toxicity to algae: EC50 - Pseudokirchneriella subcapitata (previous names: Raphidocelis subcapitata, Selenastrum capricornutum) - 3.57 mg/L - 72 h.
- Toxicity to microorganisms: EC50 - activated sludge of a predominantly domestic sewage - 56 mg/L - 3 h. Remarks:Respiration rate.
Persistence and degradability
Persistence of 50 ppm o-phenylphenol in an activated sludge screening test was less than 9 days(1); an initial concn of 50 ppm was reduced 30% in 7 days in an anaerobic digestion test(1); an initial concn of 100 ppm was reduced 43% in 54 hr in an aerated lagoon simulation(1); an initial concn of 100 ppm was reduced 20% in 168 hr in retention pond simulation(1). Acclimated treatment plant cultures completely degraded 50 ppm o-phenylphenol within 30 hr in a BOD study(2). In an aerobic BOD dilution study using an activated sludge inocula, 100-150 ppm were completely degraded in 8-16 days, although lag periods of 5-13 days were observed(3). Five-day theoretical BODs of 1.2-29.7% were measured using 1-50 ppm o-phenylphenol with the theoretical BOD generally decreasing with an increase in concn(4). In Sapromat respirometer studies using industrial activated sludge, inoculum from a communal clarification plant, or a sewage inocula, 5-day theoretical BODs ranged from 50-100%(5).
Bioaccumulative potential
An estimated BCF of 51 was calculated for o-phenylphenol(SRC), using a log Kow of 3.09(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is moderate. However, bioconcentration studies on compounds which are structurally similar suggest that bioconcentration may be lower than that indicated by the regression-derived equations due to the ability of aquatic organisms to readily metabolize this class of compounds. Animals excrete o-phenylphenol as the parent compound and as the glucuronide and sulfate conjugates(4).
Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc for o-phenylphenol can be estimated to be 6,700(SRC). According to a classification scheme(2), this estimated Koc value suggests that o-phenylphenol is expected to be immobile in soil. In laboratory aqueous sorption studies using two types of bentonite clay, between 47 and 96.4 percent of added o-phenylphenol was sorbed after 24 hr(3).
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
