Handling and Storage

Safe handling precautions, storage conditions, and workplace requirements

Handling

Handle in accordance with good industrial hygiene and safety practice. When using do not eat, drink or smoke. Hands and/or face should be washed before breaks and at the end of the shift.

Storage

Avoid extreme heat. Keep container tightly closed and in a well-ventilated place. Keep away from sources of ignition - No smoking.

Hygiene

When using do not eat, drink or smoke. Hands and/or face should be washed before breaks and at the end of the shift.

Fire prevention

The product is combustible. Prevent electrostatic charge - sources of ignition should be kept well clear - fire extinguishers should be kept handy.

08

Exposure Controls / PPE

Occupational exposure limits, engineering controls, and protective equipment

Hands

Chemical resistant protective gloves (EN 374) Suitable materials also with prolonged, direct contact (Recommended: Protective index 6, corresponding > 480 minutes of permeation time according to EN 374): e.g. nitrile rubber (0.4 mm), chloroprene rubber (0.5 mm), polyvinylchloride (0.7 mm) and other Manufacturer's directions for use should be observed because of great diversity of types. Supplementary note: The specifications are based on tests, literature data and information of glove manufacturers or are derived from similar substances by analogy. Due to many conditions (e.g. temperature) it must be considered, that the practical usage of a chemical-protective glove in practice may be much shorter than the permeation time determined through testing.

Eyes

Tightly fitting safety goggles (cage goggles) (e.g. EN 166) and face shield.

Respiratory

Respiratory protection in case of vapour/aerosol release. Gas filter for gases/vapours of organic compounds (boiling point >65 °C, e. g. EN 14387 Type A)

Skin/Body

Body protection must be chosen depending on activity and possible exposure, e.g. apron, protecting boots, chemical-protection suit (according to EN 14605 in case of splashes or EN ISO 13982 in case of dust).
