Chapter 44: Penetration Safety

Penetrations are defined generally as openings made by drilling, cutting, or otherwise piercing a wall, ceiling, or floor. Specific requirements are defined to ensure that the hazards of penetrations are evaluated and controlled to protect personnel. The penetration safety program and its requirements apply to all personnel, SLAC and subcontractor, performing penetrations at SLAC. Exemptions: excavations are not within the scope of this program and the requirements of this program do not apply to the placement of thumbtacks, picture nails, or similar items in a hollow wall or ceiling that do not go beyond the thickness of the external material (that is, sheetrock, wood, plaster board).
