Description of key information
- Combination of alkali/thermal burns caused by Black liquor can damage skin and eyes through direct exposure, cause respiratory effects if inhaled and gastrointestinal effects if ingested.
Additional information
Three occupational accident cases in Canada were reported regarding burn injuries caused by Black liquor (Winemaker et al. 1992). According to the article Black liquor (pH 11-13) is used typically at a temperature of 85-95 ºC placing workers at risk to a combination of thermal and chemical burn. Combination of alkali/thermal burns caused by Black liquor can damage skin and eyes through direct exposure, the respiratory tract if inhaled and the gastrointestinal tract if ingested.
Black liquor has shown to be corrosive in the in vitro skin and eye irritation/corrosion tests, which confirms the risk of thermal and chemical burns.
Additional information:
Finnish handbook for Personal Protective Equipments for recovery boiler workers, published by the Finnish Recovery Boiler commitee as well as a publication of Paper and Timber Vol. 89/No 6/2007 show that chemical sprays pose health hazard to recovery boiler plant workers. Hot alkaline splashes penetrate rapidly through thin protective clothes and incur burns. Black liquor splash can incur deep ulceration or corrosive damage to the skin.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
