Isocyanates

Isocyanates are powerful irritants to the respiratory tract and mucus membranes around the eyes. Due to their widespread use, isocyanates are considered the leading causes of occupational asthma in the UK. Isocyanate-related asthma typically develops after continuous exposure from several months to years. Once sensitised, extremely low respiratory levels of isocyanate can elicit asthmatic responses.

To fully evaluate employees’ exposure levels and the effectiveness of existing engineering controls a technical assessor from Sysco Environmental will carry out personal and static isocyanates exposure monitoring. We can also provide our clients with biological monitoring method for isocyanates exposure through urine samples. Exposure to isocyanates can occur at all stages of the manufacturing process from initial surface application to final curing or cutting of materials.

Our isocyanates exposure monitoring program includes:

• Assessment of all potential exposure sources and paths
• Evaluation of employees’ working and exposure patterns
• Collection of air samples for assessment of inhalation exposure
• Collection of skin samples for assessment of skin exposure
• Collection of urine samples for assessment of total bioburden, if required
• Provision of gloves breakthrough assessment patches
• Use and adequacy of existing control measures
• Evaluation of suitability of respiratory protection and RPE checks
• Evaluation of existing management controls
