First-aid measures

General advice Move out of dangerous area. Place and transport victim in stable

position (lying sideways). Remove contaminated clothing immediately

and dispose of safely.

Inhalation Move to fresh air. Keep patient warm and at rest. If symptoms persist,

call a physician.

Skin contact Wash off thoroughly with plenty of soap and water, if available with

polyethyleneglycol 400, subsequently rinse with water.

Eye contact Rinse immediately with plenty of water, also under the eyelids, for at

least 15 minutes. Remove contact lenses, if present, after the first 5

minutes, then continue rinsing eye. Get medical attention if irritation

develops and persists.

Ingestion Rinse mouth. Do NOT induce vomiting. Call a physician or poison

control center immediately.

Most important symptoms and effects, both acute and delayed

Symptoms No symptoms known or expected.

Indication of any immediate medical attention and special treatment needed

Treatment Treat symptomatically. In case of ingestion gastric lavage should be

considered in cases of significant ingestions only within the first 2

hours. However, the application of activated charcoal and sodium

sulphate is always advisable. There is no specific antidote.

Fire-fighting measures

Suitable Use water spray, alcohol-resistant foam, dry chemical or carbon

dioxide.

Special hazards arising

from the substance or

mixture

In the event of fire the following may be released:, Hydrogen chloride

(HCl), Hydrogen cyanide (hydrocyanic acid), Carbon monoxide (CO),

Nitrogen oxides (NOx)

Advice for firefighters

Special protective

equipment for firefighters

In the event of fire and/or explosion do not breathe fumes. In the event

of fire, wear self-contained breathing apparatus.

Further information Contain the spread of the fire-fighting media. Do not allow run-off from

fire fighting to enter drains or water courses.

Accidental release measures

Precautions Avoid contact with spilled product or contaminated surfaces. Use

personal protective equipment.

6.2 Environmental

precautions

Do not allow to get into surface water, drains and ground water.

6.3 Methods and materials for containment and cleaning up

Methods for cleaning up Use mechanical handling equipment. Clean contaminated floors and

objects thoroughly, observing environmental regulations. Keep in

suitable, closed containers for disposal.

Handling and storage

Advice on safe handling Use only in area provided with appropriate exhaust ventilation.

Advice on protection

against fire and explosion

Keep away from heat and sources of ignition.

Hygiene measures Avoid contact with skin, eyes and clothing. Keep working clothes

separately. Wash hands before breaks and immediately after handling

the product. Remove contaminated clothing immediately and dispose of

safely. Garments that cannot be cleaned must be destroyed (burnt).

7.2 Conditions for safe storage, including any incompatibilities

Requirements for storage

Exposure controls / personal protection

Respiratory protection If product is handled while not enclosed, and if contact may occur:

Wear respirator with a particle filter mask (protection factor 4)

conforming to European norm EN149FFP1 or equivalent.

Respiratory protection should only be used to control residual risk of

short duration activities, when all reasonably practicable steps have

been taken to reduce exposure at source e.g. containment and/or

local extract ventilation. Always follow respirator manufacturer's

instructions regarding wearing and maintenance.

Hand protection Please observe the instructions regarding permeability and

breakthrough time which are provided by the supplier of the gloves.

Also take into consideration the specific local conditions under which

the product is used, such as the danger of cuts, abrasion, and the

contact time.Wash gloves when contaminated. Dispose of when contaminated

inside, when perforated or when contamination on the outside cannot

be removed. Wash hands frequently and always before eating,

drinking, smoking or using the toilet.

Material Nitrile rubber

Rate of permeability > 480 min

Glove thickness > 0,4 mm

Protective index Class 6

Directive Protective gloves complying with EN

374.

Eye protection Wear goggles (conforming to EN166, Field of Use = 5 or equivalent).

Skin and body protection Wear standard coveralls and Category 3 Type 5 suit.

If there is a risk of significant exposure, consider a higher protective

type suit.

Wear two layers of clothing wherever possible. Polyester/cotton or

cotton overalls should be worn under chemical protection suit and

should be professionally laundered frequently.
