automotive paint shop where urethane containing polyisocyanates is sprayed
daily. The study concluded the workers were protected at an adequate
level (they wore protective suits and were using a forced air breathing
system). I'm not advocating not using automotive polyurethanes, but if
you're going to use them, be aware of the dangers and take the precautions
recommended by the paint manufacturers. I used to spray Imron with great
results, but am now experimenting with other paints to eliminate the hazard.<o:p></o:p></span></font></p>

the most debilitating health effects from workplace exposure to diisocyanates
are respiratory and dermal sensitization. Exposures can lead to sensitization
depending on the type of exposure, the exposure concentration, the route of
exposure, and individual susceptibility. Dermal sensitization can result in
such symptoms as rash, itching, hives, and swelling of the extremities.<sup>18,21</sup>
Respiratory sensitization from exposure to diisocyanates results in the typical
symptoms of asthma. Estimates of the prevalence of diisocyanate-induced asthma
in exposed worker populations vary considerably; from 5% to 10% in diisocyanate
production facilities,<sup>22,23</sup> to 25% in polyurethane production
plants,<sup>22,24</sup> and 30% in polyurethane seatcover operations.<sup>25</sup><br>
<br>
A worker suspected of having diisocyanate-induced sensitization will present
with symptoms of traditional acute airway obstruction; e.g., coughing,
wheezing, shortness of breath, tightness in the chest, nocturnal awakening,
etc.<sup>18,20</sup> Upon first exposure to diisocyanates, the worker may
develop an asthmatic reaction immediately or several hours after exposure,
after the first months of exposure, or after several years of exposure.<sup>18,20,23,26,27</sup>
some evidence exists which suggests that the onset of sensitization occurs
after a mean exposure interval of two years.<sup>28</sup> After sensitization,
any exposure, even to concentrations below any occupational exposure limit or
standard, can produce an asthmatic response which may be life threatening. This
asthmatic reaction may occur minutes after exposure (immediate), several hours
after exposure (late), or a combination of both immediate and late components
after exposure (dual).<sup>20,26</sup> The late asthmatic reaction is the most
common occurring in approximately 40% of diisocyanate-sensitized workers.<sup>29</sup>
Recurrent nocturnal asthma has been described in workers sensitized to TDI and
MDI.<sup>30,31</sup> An improvement in symptoms may be observed during periods
away from the work environment (weekends, vacations).<sup>18,20,26</sup><br>
<br>
The percentage of sensitized workers with persistent symptoms of asthma after
years of no exposure may be 50% or higher. Studies have shown that workers with
persistent asthma have a significantly longer duration of symptoms prior to
diagnosis, larger decrements in pulmonary function, and a severe degree of
nonspecific bronchial hyperactivity at diagnosis.<sup>26</sup> These data
suggest that prognosis is improved with early diagnosis of diisocyanate-induced
respiratory sensitization and early removal from diisocyanate exposure. This
emphasizes the need to minimize workplace exposure concentrations, and for
active medical surveillance of all workers potentially exposed to
diisocyanates.<o:p></o:p></span></font></p>
