CIS 77-704 Criteria for a recommended standard - Occupational exposure to phenol.
Recommendations are made for the prevention of occupational diseases due to exposure to phenol. The time-weighted average exposure (10h working day) should not exceed 20mg/m3 over a 40h week. The ceiling concentration is fixed at 60mg/m3 for any 15min period. Other recommendations relate to medical supervision, labelling, personal protection, information of employees, work practices, sanitation, monitoring and recordkeeping. The criteria on which the recommendations are based are discussed under the following heads: biological effects of exposure, environmental data, development of the standard, research priorities. Procedures for sampling and analysis in air are detailed and useful additional information is given in appendices.

Use of chlorophenols as fungicides in sawmills.
Occupational hygiene studies at the trimming, grading and packaging positions of 2 sawmills, with results of chromatographic analysis of 3 commercial chlorophenol formulations and of wood dust. Chemistry and toxicology of chlorophenols. The most frequent impurities of the commercial chlorophenols, which are applied by dipping or spraying, were chlorinated phenoxyphenols, diphenyl ethers, dibenzofurans and dibenzodioxins. Analysis of wood dust showed the impurities to be enriched in relation to the chlorophenols themselves, probably because of their low volatility and high stability. Contaminant concentrations were much higher at the plant employing spraying as method of application; the dipping method is therefore preferable, provided that the highly contaminated sludge from the dipping tank is adequately disposed of.

Study of formaldehyde and phenol concentrations in the workplace air of foundries
Untersuchung der Formaldehyd- und Phenolkonzentrationen in der Luft von Giessereiarbeitsplätzen [in German]
After a brief presentation of the health hazards of phenol and formaldehyde, the methods and results of concentration measurements of these substances in the moulding shop of a large foundry are given. Measurements were made with personal samplers which permitted continuous monitoring of air concentrations. The excursions above the maximum permissible concentrations observed should be eliminated by the use of less toxic resin/hardener mixtures, formaldehyde-binding substances and appropriate ventilation.

Study of the combined effect of phenol and formaldehyde in a warm atmosphere (+30°)
Izučenie sovmestnogo dejstvija fenola i formal'degida v kombinacii s povyšennoj temperaturoj vozduha [in Russian]
Results of animal experiments for the establishment of standards for use of phenol-formaldehyde resins in the construction of ships sailing in the tropics. Chronic exposure to 0.023mg/m3 phenol and 0.024mg/m3 formaldehyde at 30°C produces a toxic effect characterised by changes in the erythropoiesis, the phagocytic activity of the neutrophiles, neuromuscular functions, etc. As a result of these and other experiments with lower concentrations (at the same temperature) the authors recommend 0.005mg/m3 and 0.006mg/m3 as TLVs for combinations of phenol and formaldehyde, respectively.

Decontamination procedures for skin exposed to phenolic substances.
Spraying or swabbing with a mixture of polyethylene glycol 300/methylated spirits (PEG-300/IMS) (2:1 by volume) was shown to markedly reduce mortality, systemic intoxication and burns from exposure to phenol, cumene hydroperoxide, or phenol/acetone cleavage product. In the case of sulfuric acid and sodium hydroxide, PEG-300/IMS (2:1 by volume) was slightly less effective than water as a decontaminant. The mixture did not cause permanent eye irritation and should not present a hazard when used as a spray.

Histopathological liver changes after chronic experimental phenol poisoning
Histologični promeni v černija drob pri eksperimentalno hronično otravjane s fenol [in Bulgarian]
Results of research in 35 rabbits given 0.18g/kg phenol daily for 7-35 days by the intravenous route. The authors noted severe dystrophic changes (non-fatty parenchymal and vacuolar dystrophy) of the hepatic parenchyma, necrobiotic lesions of the hepatocytes, a considerable decline (to complete disappearance) in glycogen and a very great fall in cytoplasmic ribonucleic acid. In animals in which administration was stopped after 35 days they noted a reversal of the dystrophic processes and the return of glycogen and RNA levels in the liver cells to normal values.

CIS 75-482 Occupational leucoderma.
A number of phenol and catechol compounds widely used in industry can produce cutaneous depigmentation when applied topically to the skin. Outbreaks of leucoderma have occurred in workers exposed to para-tertiary butylphenol and butylcatechol and in hospital workers exposed to phenols in germicidal disinfectants. Chemical workers engaged in the production of alkyl phenols are also at risk. Further research is needed to clarify the mechanism by which these compounds can induce cutaneous depigmentation.

Chloracne from the accidental production of tetrachlorodibenzodioxin.
Following the accidental production of 2,3,7,8-tetrachlorodibenzodioxin (dioxin) due to an exothermic reaction at a plant manufacturing 2,4,5-trichlorophenol, 79 cases of chloracne were recorded, many of them severe. Similar incidents are known to have occurred both in Europe and the USA, often resulting in widespread illness and even deaths. A new plant now in operation for 3 years is designed in such a way that an exothermic reaction is not possible. The trichlorophenol which is produced is tested for dioxin contamination by instantaneous gas-liquid chromatography.

Histological changes in the internal organs of experimental animals under the effect of phenol.
Account of animal experiments carried out to study the histological and histochemical changes induced by a single dose of phenol (1/10 of the lethal dose 50 = 0.18g/kg) in the liver, lungs, myocardium, aorta and small intestine. The authors observed dystrophic, and sometimes even necrotic, liver cell changes which were particularly evident 35 days after the administration of phenol. The changes observed in the tissues of the other organs showed that phenol is not only hepatotoxic, but also affects other parenchymatous organs including the large arteries.

Therapy for percutaneous phenol poisoning
Therapiemöglichkeiten bei perkutaner Phenolvergiftung [in German]
Paper read at the 1st International Symposium of Plant Physicians of the Chemical Industry (Ludwigshafen, 27-29 April 1972). Emergency treatment of skin contact with phenol is a controversial matter and animal experiments were undertaken to clarify the situation. It was found that irrigation with water has an considerable detoxifying effect. Polyethyleneglycol 400 had the most pronounced effect by far; polyethyleneglycol 300 also proved highly effective. It is recommended that phenol skin contamination should be treated by brief water irrigation followed by decontamination with polyethyleneglycol. Intravenous administration of sodium bicarbonate is advocated in in very severe cases. (For the complete proceedings of this symposium, see CIS 73-32).

Automated determination of total phenol in urine
A fully automated method has been developed to determine total phenol in urine. The reagents include a buffer solution, sulphuric acid, 4-aminoantipyrine and an oxidant. The analytical procedure involves hydrolysis of conjugated phenols and steam distillation, followed by colorimetric phenol determination in the distillate. Urine samples (1-2mL) are run sequentially at the rate of 10 per hour; the precision obtained is 1.6ppm per litre. The method could be used routinely to assess benzene exposure.
