Title Chemical hazard alert notice - Hydroquinone (1,4 Benzenediol)
Bibliographic information HSE Books, P.O. Box 1999, Sudbury, Suffolk CO10 2WA, United Kingdom, June 2000. 3p.
Abstract This guidance note provides information on the health effects of exposure to hydroquinone. In view of the information now available, the HSC is studying the possible withdrawal of the current exposure limits from 2001. Hydroquinone is used in the manufacture of photographic developing reagents. It is also used as an intermediate in a number of processes, such as the production of p-benzoquinone for use in agrochemical production, and the manufacturing of methacrylate and methacrylic acid, UV curable resins for printing ink production, acrylonitrile and thermoplastic monomer. There is clear evidence showing that hydroquinone is mutagenic; it is a skin and eye irritant and can cause skin sensitization reactions and damage to the eyes. Exposure to hydroquinone should be controlled by a combination of engineering, process and control measures (ventilation, personal protective equipment).
