Technical Details & Test Data
- Fire-fighting Measures
Suitable extinguishing agents
Water, foam, dry chemical, carbon dioxide (CO2).
Potential combustion products
Carbon dioxide (CO2), carbon monoxide (CO). Formation of further decomposition and oxidation products depend upon the fire conditions. Under special fire conditions traces of other toxic substances are possible.
Special protective equipment
Wear a self-contained breathing apparatus. If exposed to combustion fumes bring the victim into fresh air.
Further information
Dispose of fire debris and contaminated extinguishing water in accordance with official regulations..
Safety & Health
- Safety Measures
The general industrial safety measures should be considered. A thermal damage during machining should be avoided.
Storage & Handling
- Machining
The product can be machined with standard machinery and tools. Before machining the product should be stored at room temperature 24 h. Evacuate swarf to prevent slipping or tripping. Observe the maximum allowable concentration of dust and formaldehyd levels on the working area which apply in your country. Wear safety goggles during machining. General dust limit value: Respirable dust (6 mg/m3); Inhalable dust (10 mg/m3 ).
- Storage
The products shall be stored indoor to keep away from any source of degradation such as sunlight, UV-jets, ionizing radiation, chemicals.
