8. CONCLUSIONS AND REGULATORY OBLIGATIONS Hazard classification Based on the information provided, the notified polymer is classified as hazardous according to the Approved [NOHSC:1008(2004)] with the following risk phrase: Criteria for Classifying Hazardous Substances Xn; R42 May cause sensitisation by inhalation and The classification of the notified polymer using the Globally Harmonised System for the Classification and Labelling of Chemicals (GHS) (United Nations 2009) is presented below. This system is not mandated in and carries no legal status but is presented for information purposes. Hazard category Hazard statement Respiratory May cause allergy or asthma symptoms or breathing 1 sensitisation difficulties if inhaled Human health risk assessment Under the conditions of the occupational settings described, the notified polymer is not considered to pose an unreasonable risk to the health of workers. When used in the proposed manner, the notified polymer is not considered to pose an unreasonable risk to public health. Environmental risk assessment Based on the reported use pattern, the notified polymer is not considered to pose an unreasonable risk to the environment. Recommendations Hazard Classification and Labelling Safe Work Australia, should consider the following health hazard classification for the notified polymer: R42 may cause sensitisation by inhalation Conc. ≥ 1%: Health Surveillance As the notified polymer contains isocyanate functional groups, employers should carry out health surveillance for any worker who has been identified in the workplace risk assessment as having a history of isocyanate sensitivity, asthma or other pulmonary condition and who may be adversely affected by isocyanate exposure. Occupational Health and Safety Employers should implement the following isolation and engineering controls to minimise occupational exposure to the notified polymer during reformulation and use of products containing the notified polymer: Ventilation systems including local exhaust ventilation when inhalation exposure could occur, where possible. Automated processes, where possible. Ventilated spray booths during spray application, where possible. Spray application to occur in well-ventilated areas when spray booths cannot be used.
