General advice

Consult a physician. Show this safety data sheet to the doctor in attendance.

If inhaled

Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.

In case of skin contact

Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention .

In case of eye contact

First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

If swallowed

Rinse mouth. Do NOT induce vomiting. Refer for medical attention .

4.2 Most important symptoms/effects, acute and delayed

Poisonous; may be fatal if inhaled, swallowed or absorbed through skin. Irritating to skin and eyes; direct contact may cause burns. Rats receiving lethal doses via oral, subcutaneous or intraperitoneal routes displayed similar symptoms: restlessness, increased breathing rate and motor weakness followed by tremors, chronic convulsions, dyspnea, coma and death. (USCG, 1999)

Excerpt from ERG Guide 153 [Substances - Toxic and/or Corrosive (Combustible)]: TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution. (ERG, 2016)

4.3 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/

5.Fire-fighting measures

  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: 2-Chlorophenol, present at 100 mg/L, reached 0% of its theoretical BOD in 2 weeks using an activated sludge inoculum(1). In an aerobic screening test, the microorganism Pseudomonas gladioli was able to degrade 2-chlorophenol 74.6% after an incubation period of 24 hours and an initial concn of 8.78 ug/ml(2). 2-Chlorophenol was 100% degraded by a microbial mixture inoculum after an incubation time of 96 hours(3). The aerobic biodegradation of 2-chlorophenol in the cyclone fermentor system revealed 0% remaining after 200 hours and a lag time of 25 hours; this corresponds to a half-life of 140 hours(4). Incubation at 30°C resulted in incomplete removal of 2-chlorophenol, which ceased after 48 hours. 64.8% of 2-chlorophenol was removed; however, only 30.2% of the total chloride was released. Degradation proceeded via meta-cleavage and a build-up of the metabolite 3-chlorocatechol was observed(5). 2-Chlorophenol reached 38.0% of its theoretical BOD in river water obtained from the Jilin section of the Songhua River, China. A test concn of 2 mg/L (based on the Theoretical Oxygen Demand for 2-chlorophenol) was tested at 15-20°C, pH 6.8-7.0, and a dissolved oxygen concn of 8.0 mg/L using standard iodometric tritration(6).

12.3 Bioaccumulative potential

BCF's of 214 (log BCF = 2.33) in bluegill sunfish after 28 days exposure(1), 14 to 29 in carp(2), and 6 for goldfish(3) were determined for 2-chlorophenol. According to a classification scheme(4), BCF values of zero to 30 are low and from 100 to 1,000 are high.

12.4 Mobility in soil

Experimentally determined Koc's for 2-chlorophenol in various soil conditions were reported as 51 in clay loam soil and 398 in unspecified soil(1). Koc values of 3,981 in coarse sediment, and 5,012 in fine sediment have also been reported(1). According to a classification scheme(2), 2-chlorophenol will exhibit high to moderate mobility depending on soil type(SRC).
