Substitute or replace with a safer substance. Isocyanates and other chemicals classed as dangerous goods must be stored in accordance with the Storage of Dangerous Goods Regulations administered by the Department of Minerals and Energy. Specific requirements for isocyanates Manufacturing processes where isocyanates are used should be designed so that isocyanates are not released into the workplace atmosphere. Skin contact also needs to be minimised. Other ways of minimising exposure are listed below.
Mechanical ventilation is required when isocyanates are heated.
Where isocyanates are sprayed, LEV systems will be required and must be designed to remove the spray mist or aerosols. This requires careful design and regular maintenance. Respiratory protection must be carefully selected based on information available through the risk assessment process. As a guide, positive pressure air supplied respirators will be required where materials containing isocyanates are sprayed. The concentration of isocyanate present in the air will determine the level of protection required in other circumstances.
