HANDLING AND STORAGE

7.1 HANDLING

• These sheets are heavy and unwieldy. They should be handled with care, particularly in windy locations or outdoors.
• If broken or chipped the resultant edges can be sharp and cause cuts to skin and eyes.
• Take precautionary measure against static discharges.
• Process Hazards
• All polymers degrade to some extent at their processing temperature, an effect which increases with increasing temperature.
• Under normal conditions where thermoforming temperatures will not exceed 200°C thermal decomposition product will include methyl methacrylate.
• Certain machining operation eg laser cutting can give rise to toxic and corrosive fumes. Adequate ventilation MUST be used.

7.2 STORAGE

Keep away from heat. Store vertically on A-frames
Storage Temperature : Below 40°C

EXPOSURE CONTROLS/ PERSONAL PROTECTION

Provide adequate ventilation, including appropriate local extraction if dusts, fumes or vapours are likely to be evolved. Consideration should be given to the work procedures involved and the potential extent of exposure as they may determine whether a higher level of protection is required. Local extraction close to the cutting head must be used when laser cutting. When suitable engineering controls are not fitted or are inadequate, wear suitable protective equipment.

The following information is given as general guidance.

Respirators:

NORMAL HANDLING:
Not normally required.

PROCESSING:

• Dust: A suitable dust mask or dust respirator with filter type P may be appropriate. (EN141/EN143).
• Hazardous Reactions: None known If high levels above the Occupational Exposure Limit are likely - A suitable mask with filter type A may be appropriate. (EN141/ EN143).
• Eye Protection: Wear eye/ face protection. Safely spectacles/ goggles/ full face shield.
• Gloves : Sharp edges mau cause cuts. Wear Suitable gloves.
