Serious Eye Damage/Eye Irritation

Treatment:

Treat symptomatically.

Fire-fighting measures

General Fire Hazards:

Standard procedure for chemical fires. Use extinguishing measures that are appropriate to local circumstances and the surrounding environment. Dust can form an explosive mixture with air. Fire residues and contaminated fire extinguishing water must be disposed of in accordance with local regulations.

5.1 Extinguishing media

Suitable extinguishing media:

Water spray. foam Dry chemical. Carbon dioxide

Unsuitable extinguishing media:

High volume water jet

5.2 Special hazards arising from the substance or mixture:

May be released in case of fire: carbon monoxide, carbon dioxide, organic products of decomposition.

5.3 Advice for firefighters

Special fire fighting procedures:

Avoid dust formation. In the event of fire, cool the endangered containers with water. Take precautionary measures against static discharges.

Special protective equipment for fire-fighters:

Wear self-contained breathing apparatus.

Accidental release measures

6.1 Personal precautions, protective equipment and emergency procedures:

Assure sufficient ventilation. Wear protective gloves/protective clothing/eye protection/face protection. Keep away sources of ignition. Use breathing apparatus if exposed to vapours/dust/mist/aerosol. Avoid breathing dust. Do not eat, drink or smoke when using this product. Wash hands thoroughly with soap and water after handling.

6.1.1 For non-emergency personnel:

Evacuate area and do not approach spilled product. ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area). For personal protection see section 8.

6.1.2 For emergency responders:

No data available.

6.2 Environmental Precautions:

Prevent product from getting into drains/surface water/groundwater.

6.3 Methods and material for containment and cleaning up:

Take up mechanically. Dispose of in accordance with regulations.

6.4 Reference to other sections:

For personal protection see section 8. For disposal considerations see section 13.

Handling and storage

7.1 Precautions for safe handling:

Avoid the formation and deposition of dust. Provide extraction if dust raised. Keep container tightly closed. Do not inhale dust. Avoid contact with skin and eyes. Do not eat, drink or smoke during use. In the event of fire, cool the endangered containers with water. Take precautionary measures against static discharges.

7.2 Conditions for safe storage, including any incompatibilities:

Store in a well-ventilated place. Keep container tightly closed. Keep only in the original container at a temperature not exceeding 30 °C. Protect from the action of light. Do not store together with acids or alkalis. Do not store together with strong oxidizing agents. See section 10: Materials to avoid Observe prohibition against storing together!

7.3 Specific end use(s):

We are unaware of any specific end uses which go beyond the data reported in Section 1.

Individual protection measures, such as personal protective equipment

Eye/face protection:

tightly fitting goggles Ensure that eyewash stations and safety showers are close to the workstation location.

Hand Protection:

Material: butyl rubber gloves (minimal thickness 0.3 mm)

Break-through time: 480 min

Guideline: EN 374

Additional Information: 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., The above mentioned hand protection is based on special knowledge of the chemical and the intended handling of this product, however, it still may not be suited for all workplaces. A qualified hazard assessment should be made prior to the onset of work in order to determine the suitability of gloves for specific working environments and processes., Gloves should be discarded and replaced if there is any indication of degradation or chemical breakthrough.

Disposal considerations

13.1 Waste treatment methods

General information:

Dispose of waste and residues in accordance with local authority requirements.

Disposal methods:

Waste is hazardous. It must be disposed of in accordance with the regulations after consultation of the competent local authorities and the disposal company in a suitable and licensed facility. Strictly controlled conditions during disposal or treatment to air, wastewater and waste. Do not add wastewater to a biological wastewater treatment plant Bring wastewater containing AOX for professional disposal. 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:

Contaminated packaging should ideally be emptied; it can then be recycled after having been decontaminated. Packaging that cannot be cleaned should be disposed of professionally. Uncontaminated packaging may be taken for recycling.
