HEALTH & SAFETY

No special precautions are required. However, to avoid potential for dust generation exists, please wear appropriate personal protection gear (safety goggles, protective clothing and dust mask). For more information please check the material safety data sheet, available upon request.

A health and safety data sheet is available from Promat and, as with any other material, should be read before working with the board.

WASTE DISPOSAL

The board is not classified as a dangerous substance so no special provisions are required regarding the transportation and the disposal of the product to landfill. They can be placed in on-site rubbish skips with other general building waste which should then be disposed by a registered contractor in the appropriate and approved manner.
