Développement d’un nouveau dispositif d’échantillonnage des aérosols de diisocyanate-4-4’ de diphénylméthane (MDI)
La pulvérisation de produits à base de MDI est une pratique commune à laquelle s'adonnent de nombreux travailleurs. Un exemple d'application de produits à base de MDI est le revêtement de mousse isolante commercial et résidentiel. Durant l'application de ce type de produit, les travailleurs sont exposés aux aérosols de MDI. Le MDI est un produit chimique reconnu comme étant un agent sensibilisant pouvant provoquer l'asthme professionnel. Afin de minimiser l'exposition des travailleurs au MDI, une surveillance environnementale...
Genetic Variants in the Major Histocompatibility Complex Class I and Class II Genes Are Associated With Diisocyanate-Induced Asthma
Objective: To investigate the association between single nucleotide polymorphisms (SNPs) located across the major histocompatibility complex and susceptibility to diisocyanate-induced asthma (DA). Methods: The study population consisted of 140 diisocyanate-exposed workers. Genotyping was performed using the Illumina GoldenGate major histocompatibility complex panels. Results: The HLA-E rs1573294 and HLA-DPB1 rs928976 SNPs were associated with an increased risk of DA under dominant (odds ratio [OR], 6.27; 95% confidence interval [CI], 2.37 to 16.6; OR, 2.79, 95% CI, 0.99 to 7.81, respectively) and...
Isocyanate paint spraying
Safely managing spray booths and rooms This guidance is aimed at vehicle bodyshop owners, managers and supervisors, their employees (particularly paint sprayers) and suppliers. It will also be useful to industries other than motor vehicle repair where there is spraying of isocyanate-containing paints and lacquers. Source: http://www.hse.gov.uk/pubns/books/hsg276.htm
Cross-Sectional Survey of Workers Exposed to Aliphatic Diisocyanates Using Detailed Respiratory Medical History and Questions Regarding Accidental Skin and Respiratory Exposures
Objectives: To identify possible cases of occupational asthma and assess accidental skin and inhalation exposures to aliphatic diisocyanates. Methods: Seventy-three employees from two plants, manufacturing or producing aliphatic diisocyanates, were surveyed using a detailed respiratory history questionnaire with additional questions on accidental skin and inhalation exposures. Further reviews of medical records and interviews were used to determine whether any of 15 employees with questionable responses had developed occupational asthma. Results: No cases of occupational asthma were identified...

Automated system for indicating spray clearance times of MVR spray booths/rooms
This report describes the design and assembly of an automated device that will alert sprayers of isocyanate based paints of the presence of spray mist inside paint spray booths /rooms used in the motor vehicle repair (MVR) and other industries.

MALDI/TOF/MS analysis of isocyanates and other hazardous workplace chemicals
Mass spectrometry has long been used to analyse samples taken in the workplace, and can be combined with other techniques to increase sensitivity, selectivity and accuracy. The work summarised in this report examines the application of the recently developed Matrix Assisted Laser Desorption Ionization/ time-of-flight/ mass spectrometry (MALDI/TOF/MS) technique to the analysis of isocyanates and biocides. Isocyanates were measured on filters (to represent air monitoring) and as isocyanate/protein conjugates (representing biological monitoring). Selected biocides bound to soil samples were analysed...
Controlling isocyanate exposure in spray booths and spray rooms
This guidance is aimed at owners and managers of bodyshops and will be of use to employees (particularly paint sprayers) as well as suppliers. It supplements other HSE guidance relating to protecting people’s health from isocyanate exposure in spray booths and rooms, and the statutory 14-monthly thorough examination and test carried out on spray booths and rooms. http://www.hse.gov.uk/pubns/web36.pdf
