A crushing hazard, in contrast, is a "caught-in" hazard—the danger to the worker rests in being caught between two objects, one or both of which may be moving, and injured or killed either by physical crushing or suffocation that results from the compression of the rib cage. You can identify potential crushing hazards by looking for:

ECO GYPSUM 64 is a gypsum waste recycling plant. It is an innovative technological process that by combining a mechanical crushing action with a subsequent double dry compression, separates the gypsum and paper from the plasterboard coming from demolitions, renovations and processing scraps, fully recovering both materials.

By any name--drywall, wallboard, or plasterboard--gypsum products may not be as innocent as we once thought. Drywall, which makes up 15% of demolition and construction waste, leaches toxins and releases hydrogen sulfide gas in landfills. Virtually ubiquitous in our buildings, gypsum board is widely seen as an innocuous building material. However, in the last decade, …
