131-11-3 dimethyl phthalate		5mg/m³
1338-23-4 2-Butanone, peroxide	Peak limitation 0.2ppm	Peak limitation 1.5mg/m³
78-93-3 METHYL ETHYL KETONE	150ppm	445mg/m³	300ppm	890mg/m³

Engineering controls: Keep away from foodstuffs, beverages and feed.
Wash hands before breaks and at the end of work.
Avoid contact with the eyes and skin.

Personal protective equipment

Eye and face protection: Tightly sealed goggles.
Skin protection: Protective gloves. The glove material has to be impermeable and resistant to the product/the substance/the preparation.
