Drywall Contractor Safety Manual

Drywall contractors install, finish, repair, and remove gypsum wallboard and related wall and ceiling systems in residential, commercial, industrial, institutional, and construction environments. Employees may handle large and awkward sheets of drywall, work from scaffolds, ladders, stilts, and elevated platforms, operate cutting and fastening tools, sand joint compounds, perform overhead work, and work around electrical systems and other construction trades.

A Drywall Contractor Safety Manual helps establish consistent procedures for protecting employees during material handling, drywall installation, finishing, sanding, demolition, repair, ceiling work, equipment operation, and other drywall activities.

The safety manual should reflect the company’s drywall services, tools, equipment, materials, work locations, subcontractor activities, and employee exposures.
