  Occupational exposures to diisocyanates may cause allergic asthma. Inhalation challenges are the most important tool for the diagnosis of occupational asthma due to diisocyanates. Various diisocyanate atmospheres can be generated at IPA. A multi-steps exposure protocol is used, the dosage is constantly monitored and adjusted if necessary. The quasi-online monitoring of concentrations of airborne diisocyanates in the laboratory is done with a paper-tape monitor, which is widely used in laboratories that perform inhalation challenges worldwide, but also for monitoring of threshold limits at workplaces. The analyzer MDA 7100 (Zellweger Analytics, Inc., Lincolnshire, USA) is no longer supported by the producer. It was replaced by the successor model Single Point Monitor (Honeywell Analytics, Inc., Lincolnshire, USA), but comparative measurements are not available. It was the aim of this s.. Read More»
