Exposure Controls / PPE

Occupational exposure limits, engineering controls, and protective equipment

Engineering

Technical measures and appropriate working operations should be given priority over the use of personal protective equipment. See section 7.1.

Hands

full contact: Glove material: Nitrile rubber, Glove thickness: 0.11 mm, Break through time: > 480 min. splash contact: Glove material: Nitrile rubber, Glove thickness: 0.11 mm, Break through time: > 480 min. The protective gloves to be used must comply with the specifications of EC Directive 89/686/EEC and the related standard EN374, for example KCL 741 Dermatril® L (full contact), KCL 741 Dermatril® L (splash contact). The breakthrough times stated above were determined by KCL in laboratory tests acc. to EN374 with samples of the recommended glove types. This recommendation applies only to the product stated in the safety data sheet supplied by us and for the designated use. When dissolving in or mixing with other substances and under conditions deviating from those stated in EN374 please contact the supplier of CE-approved gloves (e.g. KCL GmbH, D-36124 Eichenzell, Internet: www.kcl.de).

Eyes

Safety glasses

Respiratory

required when dusts are generated. Recommended Filter type: Filter P 2 (acc. to DIN 3181) for solid and liquid particles of harmful substances. The entrepreneur has to ensure that maintenance, cleaning and testing of respiratory protective devices are carried out according to the instructions of the producer. These measures have to be properly documented.

Skin/Body
