3. NEVER make fastenings in spalled or cracked areas.
5. DO NOT fasten through or within 1/2" of predrilled or pre-punched holes.
4. NEVER drive power fasteners into thin or easily penetrated materials unless it is
backed by concrete or steel. When in doubt, such as when base material is
concealed, conduct a Center Punch Test (See page 6). Check continually to avoid
fastening into unsuitable material, especially in older buildings.

but not limited to cast iron, glass, tile, stone, brick, or hardened steel. Materials of
this type tend to shatter and create hazard from flying particles.
