Exposure controls / personal protection

Body protection :

Depending on the risk, wear a tight, long apron and boots

or suitable chemical protection clothing.

Respiratory protection :

In an emergency (e.g.: unintentional release of the

substance, exceeding the occupational exposure limit value)

respiratory protection must be worn. Consider the maximum

period for wear.

Respiratory protection: Gas filter A

Colour code: brown

For details on the requirements and the maximum

concentrations for use, consult the "Regeln für den Einsatz

von Atemschutzgeräten" (BGR 190).

(also possible gas filter type B or K)

Respiratory protection: insulating device

Use for concentrations above the usage limits for filter

devices, for oxygen concentrations below 17% volume, or

in circumstances which are unclear.

Eye protection :

Sufficient eye protection should be worn.

Wear glasses with side protection. If the eyes may

potentially come in contact with the liquids, then

chemical safety goggles are necessary.

Hand protection :

Use protective gloves. The glove material must be

sufficiently impermeable and resistant to the substance.

Check the tightness before wear. Gloves should be well

cleaned before being removed, then stored in a well

ventilated location. Pay attention to skin care.

Textile or leather gloves are completely unsuitable.

The following materials are suitable for protective gloves

(Permeation time >= 8 hours):

Fluoro carbon rubber - FKM (0,4 mm)

Protective gloves of the following materials should

not be worn longer than 4 hours continually

(Permeation time >= 4 hours):

Butyl rubber - Butyl (0,5 mm)

Following materials are unsuitable for protective gloves:

Natural rubber/Natural latex - NR

Polychloroprene - CR

Nitrile rubber/Nitrile latex - NBR

Polyvinyl chloride - PVC

The times listed are suggested by measurements taken at

22 degree C and constant contact. Temperatures raised

by warmed substances, body heat, etc. and a weakening of

the effective layer thickness caused by expansion can lead

to a significantly shorter breakthrough time.

In case of doubt contact the gloves' manufacturer.

A 1.5-times increase / decrease in the layer thickness

doubles / halves the breakthrough time. This data only

applies to the pure substance. Transferred to mixtures of

substances, these figures should only be taken as an aid

to orientation.

Skin protection :

Skin protection preparations do not protect sufficiently

against the substance. Wear protective gloves.

The skin must be washed with soap and water before breaks

and at the end of work.

Apply fatty skin-care products after washing.

Industrial hygiene :

If at risk of contamination, foods, beverages and other

articles of consumption must not be stored or consumed at

the work areas. Special areas are to be designated for

these purposes.

Avoid contact with skin. Do not allow the substance or its

solution to dry on the skin. In case of contact wash skin.

Avoid contact with eyes. In case of contact rinse the

affected eye(s).

Avoid inhalation of vapour/dust.

In NO case, drink alcohol.

If it is possible that there has been any contact with the

substance, then do not consume any alcohol even after work.

Avoid contact with clothing. Contaminated clothes must be

exchanged and cleaned carefully.

Provide washrooms with showers and if possible rooms with

separate storage for street clothing and work clothing.

Take care of personal hygiene.

Disposal considerations

Hazardous waste according to Waste Catalogue Ordinance

(AVV).

If there is no way of recycling it must be disposed of in

compliance with the respective national and local

regulations.

Collection of small amounts of substance:

Collect in container for toxic, flammable compounds.

Collection vessels must be clearly labelled with a

systematic description of their contents and with the

hazard symbol and the R and S phrases. Store the vessels in

a well-ventilated location. Entrust them to the appropriate

authorities for disposal.
