4.First-aid measures

4.1 Description of necessary first-aid measures

General advice

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

If inhaled

Fresh air, rest. 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. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Give a slurry of activated charcoal in water to drink. Refer for medical attention .

4.2 Most important symptoms/effects, acute and delayed

Inhalation of vapors or dust causes irritation of respiratory tract. Ingestion causes burns of mucous membranes, severe diarrhea, pallor, sweating, weakness, headache, dizziness, tinnitus, shock, and severe convulsions; may also cause siderosis of the spleen and tubular injury to the kidney. Contact with eyes causes irritation. Can be absorbed from wounds or through unbroken skin, producing severe dermatitis, methemoglobinemia, cyanosis, convulsions, tachycardia, dyspnea, and death. (USCG, 1999)

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/

  • Toxicity to daphnia and other aquatic invertebrates: no data available
  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: Resorcinol, present at 100 mg/L, reached 100% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(1,-3). Complete degradation of resorcinol occurred in 8 days (as determined by a 100% UV absorbancy loss) in a mineral salts medium using a silt loam soil inocula(4). A 5-day 61% theoretical BOD was measured using a sewage inocula(5). A 95% degradation was observed over a 0.4-day incubation period using a Warburg respirometer and an acclimated activated sludge inocula(6). A 6-day 21% theoretical BOD was observed using a Warburg respirometer and an activated sludge acclimated to aniline(7). A 12-hr theoretical BOD of 33-39% was observed using a Warburg respirometer and activated sludge acclimated to either phenol, catechol, or benzoic acid(8). A 5-day COD removal of 90% was measured in an activated sludge system(9). The half-life of resorcinol in an aerobic screening test ranged from 0.16 to 0.24 days using activated sludge acclimated to cresols(10). Half-lives of 0.5 and 4.5 hours were determined for initial concentrations of 20 and 120 ppm resorcinol, respectively, in a treatment plant simulation study over a 1-hr incubation period using inoculum from a coke wastewater treatment plant(11). Degradation of 95% in 1 day and 90% in 8 days was observed in a biological treatment simulation using activated sludge and initial concns of 138 and 500 ppm, respectively(12). Using a Warburg respirometer and a mixed-culture of bacteria adapted to phenol, 95% of initial resorcinol was degraded in 1 to 2 days(13). Resorcinol, present at 2 mg/L, reached 68.6% of its theoretical BOD in 5 days, using 150 mL of river water in the river die-away test. The source of river water inoculum was the Songhua River, Jilan Province, China, which is contaminated with substituted benzenes(14).

12.3 Bioaccumulative potential

An estimated BCF of 3 was calculated in fish for resorcinol(SRC), using a log Kow of 0.80(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 resorcinol in a clay loam soil from the Michigan State University Soils Research Farm was measured to be 10.36(1). According to a classification scheme(2), this estimated Koc value suggests that resorcinol is expected to have very high mobility in soil. The pKa1 of resorcinol is 9.30(3), indicating that this compound will exist partially in the anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4).

12.5 Other adverse effects

no data available

13.Disposal considerations

13.1 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.

Contaminated packaging

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.
