NOTES
Spray application(not product specific)
After many years of analysis of epidemiological studies we suspect that aerosols are generated through the spraying technique that potentially may be hazardous to health.
For this reason spray application can only be safely conducted if sufficient ventilation equipment is installed at the product application site which will prevent spreading of the aerosols into the workplace. A further possibility would be to carry out the spraying application in a closed system.
