Types of Chemicals Two common types of hazardous chemicals organic solvents plate-making chemicals
27
Organic Solvents Examples: Blanket and roller wash Fountain solutions Plate cleaners Glaze removers Degreasers
28
VOCs Volatile Organic Compounds Used in blanket washes Work well and evaporate quickly Pass into the air Proper ventilation is required to exhaust VOCs
29
Solvents Harmful to the skin or eyes Read containers before using to determine what to do in case of contact Typical treatment is to flush with water for 15 minutes
