Rohacell products are used as core material for sandwich structures. The base molecule of the foam(Plastic) is polymethacrylimide.

Hazards identification
This product is not classified according to CLP (EG 1272/2008); it is an article.
No particular hazards are known with its correct and appropriate use.

First Aid Measures
In case of contact with the eyes, rinse immediately with plenty of water. If any irritation persists seek
medical help and advice. Mechanical irritations are possible during machining processes.

Fire-fighting Measures
Suitable extinguishing media are foam, carbon dioxide, dry chemical and water spray.
A full water jet is an unsuitable extinguishing media for safety reasons.
As special protective equipment for fire fighting wear a self-contained breathing apparatus.

Accidental Release Measures
Dispose of in accordance with regulations.

Handling and Storage

Exposure Controls
During processing dust can be produced. Particles may affect the respiratory system. In the EEU for
dust and particulates Occupational Exposure Values exist which require monitoring. If they are obeyed
the adverse health effects are minimized.
The Occupational Exposure Value WEL (long-term) for inhalable dust or particulates is 10 mg/m³, theWEL for respirable dust is 4 mg/m³. The values are average values. Deviations from the averagevalues have to be limited to the double to avoid local irritations. In addition the 8h mean value has tobe obeyed.
An exposure protection program or applicable federal/national/provincial requirements must be
followed whenever workplace conditions warrant exposure control.

Personal Protection
Follow the usual good standards of occupational hygiene.
Respiratory protection
Dust mask may be required for machining operations.
Hand protection
Wear protective gloves against mechanical risks according to EN 388 or OSHA 1910.134 and ANSI
Z88.2.
Gloves should be replaced regularly, especially after extended contact with the product. For eachwork-place a suitable glove type has to be selected.
