Guidance on Safe Use

First-aid measures

Description of first aid measures

Inhalation:       If aerosol or mists are formed: Possible discomfort: irritation of mucous lining (nose, throat, eyes) cough, sneezing, flow of tears. Move victims into fresh air. If symptoms persist, consult a physician for treatment.

Skin Contact:       Wash off immediately with plenty of water. If symptoms persist, consult a physician for treatment.

Eye contact:       Keeping eyelid open, immediately rinse thoroughly for at least 5 minutes using plenty of water or, if necessary, eye rinsing solution. Consult an ophthalmologist.

Ingestion:       Have the mouth rinsed with water. Have patient drink plenty of water in small sips. Obtain medical attention.

Most important symptoms and effects, both acute and delayed:       None known.

Indication of any immediate medical attention and special treatment needed

Hazards:       None known.

Treatment:       If required, therapy of irritative effect. If substance has been swallowed: Early endoscopy in order to assess mucosa lesions in the oesophagus and stomach which may appear. If necessary, aspirate leftover substance.

Fire-fighting measures

Extinguishing media

Suitable extinguishing media:       Carbon dioxide or dry powder.

Unsuitable extinguishing media:       Water or Foam

Special hazards arising from the substance or mixture:       product is highly flammable. Reacts violently with water and foam. Prevent buildup of vapors or gases to explosive concentrations. Heat will increase pressure and may lead to the receptacle bursting. May be released in case of fire: carbon monoxide, carbon dioxide. May be released in case of fire: metal oxides

Advice for firefighters

Special fire fighting procedures:       Water used to extinguish fire should not enter drainage systems, soil or stretches of water. Ensure there are sufficient retaining facilities for water used to extinguish fire. Fire residues and contaminated fire extinguishing water must be disposed of in accordance with local regulations.

Special protective equipment for fire-fighters:       In case of fire: wear a self contained respiratory apparatus

Accidental release measures

Personal precautions, protective equipment and emergency procedures:       Use personal protective equipment. Ensure adequate ventilation. Do not breathe in vapours or aerosols.

Environmental Precautions:       Do not allow entrance in sewage water, soil stretches of water, groundwater, drainage systems. Avoid penetration into drainage system or in rooms situated at a lower level because of danger of explosion.

Methods and material for containment and cleaning up:       Soak up with inert absorbent material (e.g. sand, silica gel, acid binder, universal binder, sawdust). Transfer into suitable containers. To be disposed of in compliance with existing regulations.

Handling and storage

Precautions for safe handling:       Provide adequate ventilation. Avoid contact with skin and eyes. Do not inhale vapours / aerosols. Handle under inert gas atmosphere. Handle in accordance with good industrial hygiene and safety practice. The personal protective equipment used must meet the requirements of Regulation (EU) 2016/425 and amendments (CE certification). If workplace exposure limits are exceeded and/or larger amounts are released (leakage, spilling, dust) the indicated respiratory protection should be used. If there is the possibility of skin/eye contact, the indicated hand/eye/body protection should be used. Do not breathe in vapours or aerosols. Avoid contact with skin and eyes.

Conditions for safe storage, including any incompatibilities:       Take measures to prevent the build up of electrostatic charge. Use explosion-proof equipment. Keep away from heat, hot surfaces, sparks, open flames and other ignition sources. No smoking. Protect from moisture. Protect from sunlight. When repairs of the production system are to be made (e.g. welding work), the section to be repaired must be essentially free of product. Danger of explosion from residual product fumes; therefore avoid spark production through cutting, grinding, or welding work in the area of the container. Keep in inert gas. Keep container tightly sealed and store in a dry, well-ventilated place.

Exposure controls

Appropriate Engineering Controls:       Provide appropriate exhaust ventilation at machinery.

Individual protection measures, such as personal protective equipment

Eye/face protection:       close-fitting protective goggles (e.g. closed goggles)

Hand Protection:       Material: Butyl rubber.

Break-through time: >= 480 min

Glove thickness: 0.5 mm

Material: Fluorinated rubber (Viton)

Break-through time: >= 480 min

Glove thickness: 0.4 mm

Additional Information: Selection of protective gloves to meet the requirements of specific workplaces., Suitability for specific workplaces should be clarified with protective glove manufacturers., The information is based on our own tests, references from the literature and information from glove manufacturers, or derived by analogy with similar materials., Please observe that the daily duration of usage of a chemical protective glove is in practice far shorter due to the many influencing factors (e.g. temperature, mechanical strain on the glove material) than the permeation time determined acc. EN 374.

Skin and Body Protection:       suitable protective clothing - Use disposable clothing if appropriate.

Respiratory Protection:       In case of dusts/vapours/aerosols being formed or if the limit values like TLV are exceeded: use respiratory equipment with suitable filter (filter type ABEK) or wear a self contained respiratory apparatus Use only respiratory protection equipment with CE-symbol including four digit test number. The filter class for the respirator must be suitable for the maximum expected contaminant concentration (gas/vapor/aerosol/particulates) that may arise when handling the product. If this concentration is exceeded, self-contained breathing apparatus must be used. Note time limit for wearing respiratory protective equipment.

Hygiene measures:       When using, do not eat, drink or smoke. Wash face and/or hands before break and end of work. Remove contaminated or saturated clothing. Wash contaminated clothing before reuse.

Stability and reactivity

Reactivity:       No dangerous reaction known under conditions of normal use.

Chemical Stability:       Stable under recommended storage conditions. Sensitive to air.

Possibility of hazardous reactions:       Reacts violently with water.

Conditions to avoid:       Keep away from heat sources. Protect from moisture.

Disposal considerations

Disposal methods:       

With respect to local regulations, e.g. dispose of to waste incineration plant No waste key number as per the European Waste Types List can be assigned to this product, since such classification is based on the (as yet undetermined) use to which the product is put by the consumer. The waste key number must be determined as per the European Waste Types List (decision on EU Waste Types List 2000/532/EC) in cooperation with the disposal firm / producing firm / official authority.

Contaminated Packaging:       

Do not reuse empty containers and dispose of in accordance with the regulations issued by the appropriate local authorities. Incorrect disposal or reuse of this container is illegal and can be dangerous. If there is product residue in the emptied container, follow directions for handling on the container's label. Other countries: observe the national regulations.
