Polymerization user safety

A large number of publications are available on paints and coatings, plastics and concrete. Unfortunately, the information available on polymeric construction products is scattered in journals, society reports and huge tomes which cover various technologies. This has tended to confuse and befuddle rather than enlighten the uninformed user. In this book an attempt has been made to present information on the chemistry of polymers, specific polymer systems in construction and health and safety issues. 

Volatile cyanoacrylate monomers, in particular methyl and ethyl cyanoacrylates, have characteristic acrid odors. Exposure to these materials at levels in the range of 1-5 ppm results in irritation to the eyes, nose, and throat (3). It is recommended that these monomers be used in a well-ventilated area, that skin and eye contact be avoided, and that the user be familiar with the relevant safety data supplied by product manufacturers. A recent epidemiological study in workers with occupational exposure to monomer vapors concluded that there was no increased risk of pulmonary obstruction (eg, asthma) on exposure to average short-time concentrations of less than 0.5 ppm (60). Polymerization of cyanoacrylates is rapid and exothermic and particular care should be taken to avoid bums, which can result from the unexpected bulk polymerization of inadequately stabilized or contaminated monomer samples.
