04

First Aid Measures

Emergency procedures for chemical exposure incidents

Inhalation

Provide fresh air.

Skin contact

Wash with plenty of water or water and soap. In the event of a visible skin change or other complaints, seek medical advice (show label or SDS where possible).

Eye contact

Rinse immediately with plenty of water. Seek medical advice in case of continuous irritation.

Ingestion

Give several small portions of water to drink. Do not induce vomiting.

05

Firefighting Measures

Extinguishing media, specific hazards, and firefighter protection

Suitable media

water mist, extinguishing powder, alcohol-resistant foam, carbon dioxide, sand.

Unsuitable media

water jet.

Specific hazards

Risk of hazardous gasses or fumes in the event of fire. Exposure to combustion products may be a health hazard!

Firefighter Protection

Use respiratory protection independent of recirculated air. Keep unprotected persons away.

06

Accidental Release Measures

Spill cleanup procedures, containment, and environmental protection

Emergency procedures

Secure the area. Keep unprotected persons away. If material is released indicate risk of slipping. Do not walk through spilled material.

Large spill

Scoop up large quantities after dusting surfaces with sand or Fuller's earth to prevent sticking.

Environmental

Prevent material from entering surface waters, drains or sewers and soil. Close leak if possible without risk. Retain contaminated water/extinguishing water. Dispose of in prescribed marked containers.

Cleanup methods

Sweep or scrape up the spilled material and place in an appropriate chemical waste container. Clean any slippery coating that remains using a detergent / soap solution or another biodegradable cleaner. Apply sand or other inert granular material to improve traction.

Materials: detergent / soap solution or another biodegradable cleaner, sand or other inert granular material

Handling and Storage

Safe handling precautions, storage conditions, and workplace requirements

Handling

Stir thoroughly before use or catalysing. Observe information in section 8.

Storage

Store in a dry and cool place.

Fire prevention

Observe the general rules for fire prevention.

08

Exposure Controls / PPE

Occupational exposure limits, engineering controls, and protective equipment

Hands

Use of protective gloves is recommended when handling the material. Recommended glove types: Protective gloves made of nitrile rubber thickness of the material: > 0,1 mm Breakthrough time: > 480 min Recommended glove types: Protective gloves made of butyl rubber thickness of the material: > 0,3 mm Breakthrough time: > 480 min 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. Note that, due to the numerous external influences (such as temperature), a chemically resistant protective glove in daily use may have a service life that is considerably shorter than the measured break through time.

Eyes

Recommendation: protective goggles.

Respiratory

No personal respiratory protective equipment normally required.

Environmental

Prevent material from entering surface waters, drains or sewers and soil.
