Pyrolysis products
Toxic metal oxide fumes

3. Advice for firefighters
Wear self-contained breathing apparatus and protective suit.
No unprotected exposed skin areas.
Do not use a solid water stream as it may scatter and spread fire.Use extinguishing measures that are appropriate to local circumstances and the surrounding environment.

Accidental release measures

1. Personal precautions, protective equipment and emergency procedures
Ensure adequate ventilation. Evacuate personnel to safe areas. Wear personal protective equipment. Unprotected persons must be kept away. Use personal protective equipment.

2. Environmental precautions
Prevent further leakage or spillage if safe to do so. Do not flush into surface water or sanitary sewer system.

3. Methods and materials for containment and cleaning up
Use mechanical handling equipment.
Pick for disposal in tightly closed containers
Avoid dust formation.

Exposure controls / personal protection

1. Occupational exposure controls
The Personal Protective Equipment must be in accordance with EN standards:respirator EN 136, 140, 149; safety glasses EN 166; protective suit: EN 340, 463, 468, 943-1, 943-2; gloves EN 374, 511; safety shoes EN-ISO 20345.
Avoid exposure - obtain special instructions before use.
Engineering measures
Use product only in closed system.
Perform filling operations only at stations with exhaust ventilation facilities.
2. Personal protective equipment
Respiratory protection:
In the case of dust or aerosol formation use respirator with an approved filter.
Hand protection:
Glove material: Natural Latex
Break through time: > 480 min
Glove thickness: 0.6 mm
Lapren®706
Gloves must be inspected prior to use.
Replace when worn.
Remarks:Supplementary note: The specifications are based on information and tests from similar substances by analogy. Due to varying conditions ( e.g.temperature or other strains) it must be considered that the usage of a chemical protective glove in practice may be much shorter than the permeation time determined in accordance with EN 374. Since actual conditions of practical use often deviate from standardised conditions according EN 374 the glove manufacturer reccomends to use the chemical protective glove in practice not longer than 50% of the recomended permeation time. Manufacturer´s directions for use should be observed because of great diversity of types . Suitable gloves tested according EN 374 are supplied e.g. from KCL GmbH, D-36124 Eichenzell, [e-mail]
Eye protection:
Safety goggles
Skin and body protection:
Wear suitable protective equipment.
Lab coat
Complete suit protecting against chemicals

3. Environmental exposure controls
Handle in accordance with local environmental regulations and good industrial practices.
