Exposure Controls / PPE

Occupational exposure limits, engineering controls, and protective equipment

Hands

Full contact: Material: Nitrile rubber, Minimum layer thickness: 0,11 mm, Break through time: 480 min, Material tested: KCL 741 Dermatril® L. Splash contact: Material: Nitrile rubber, Minimum layer thickness: 0,11 mm, Break through time: 480 min, Material tested: KCL 741 Dermatril® L.

Eyes

Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU). Tightly fitting safety goggles

Respiratory

required when dusts are generated. Our recommendations on filtering respiratory protection are based on the following standards: DIN EN 143, DIN 14387 and other accompanying standards relating to the used respiratory protection system. Recommended Filter type: Filter type P2. 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

Flame retardant antistatic protective clothing.

Environmental

Do not let product enter drains. Risk of explosion.

Stability and Reactivity

Chemical stability, hazardous reactions, and incompatible materials

Stability

The product is chemically stable under standard ambient conditions (room temperature).

Reactivity

Forms explosive mixtures with air on intense heating. A range from approx. 15 Kelvin below the flash point is to be rated as critical. The following applies in general to flammable organic substances and mixtures: in correspondingly fine distribution, when whirled up a dust explosion potential may generally be assumed.

Hazardous reactions

Violent reactions possible with: Strong oxidizing agents

Avoid

Strong heating.

Incompatible

No data available
