Composition / Information on Ingredients

Chemical components, concentration ranges, and hazardous substance identification

Type mixture

Notes

This material does not contain any ingredients above the permitted limit(s).

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).

Symptoms: visible skin change

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

Fires can be controlled with water spray, foam or carbon dioxide. Larger fires are best fought with alcohol-resistant aqueous film forming foam (AFFF-AR).

Unsuitable media

water jet, extinguishing powder, halones.

Specific hazards

Risk of hazardous gasses or fumes in the event of fire. Exposure to combustion products may be a health hazard! With the use of water-based extinguishing agents care is required because hydrogen can be released, which accumulates after extinguishing the fire in poorly ventilated or confined areas and may refire or cause an explosion. Foam carpets may also include hydrogen or flammable vapors, which can lead to surface bursts.

Instructions

Remove sources of ignition during cleaning and absorbing.

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.

Small spill

Absorb with a neutral (non-acidic / non-basic) liquid binding material such as diatomaceous earth.

Large spill

Liquids may be recovered using suction devices or pumps. Use only air driven or properly rated electrical equipment. Use vented recovery containers.

Environmental

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

Cleanup methods

Take up mechanically. 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. Ensure adequate ventilation. Open and handle container with care. Keep container closed when not in use. Keep away from incompatible substances in accordance with section 10. Avoid formation of aerosols. In case of aerosol formation special protective measures are required (exhausting by suction, respiratory protection). Spilled substance increases risk of slipping.

Storage

Store in a dry and cool place. Protect against moisture. Store container in a well ventilated place.

Fire prevention

Keep away from sources of ignition and do not smoke. Take precautionary measures against electrostatic charging. Cool endangered containers with water.

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. In case of mist, spray or aerosol exposure wear suitable personal respiratory protection and protective suit. Suitable respiratory equipment: Filtering half-face mask, according to acknowledged standards such as EN 149. Recommended Filter type: FFP1 or equivalent filter, according to acknowledged standards such as EN 149. Observe the equipment manufacturer's information and wear time limits for respirators.

Skin/Body

protective clothing.

Environmental

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