Means the absolute closure of a pipe, line, or duct by the fastening of a solid plate (such as a spectacle blind or a skillet blind) that completely covers the bore and that is capable of withstanding the maximum pressure of the pipe, line, or duct with no leakage beyond the plate. Similarly, OSHA considers spaces that are enclosed and that are expected to contain a hazardous atmosphere to be permit spaces in 1910.146, and entry into them must conform to that standard. Inform the contractor that all contractors and subcontractors are required to follow a PRCS Program that complies with OSHA regulations and NCSU entry requirements. A space that is a confined space but has no recognized hazards that would otherwise make it a permit space. For entries using Alternate Procedures: Atmospheric hazards and potential atmospheric hazards can be controlled using forced air ventilation. Flowable physical hazards, such as steam, water, or liquids contained in tanks, or enclosed in sealed piping and piping components such as valves and traps must be isolated outside the permit space and can only be isolated by one of the following: Physical hazards from moving or movable parts or from falling parts or equipment can be isolated by immobilizing, blocking, chocking, or restraining movable parts, and by blocking and supporting parts that can fall. Avoid using visual hand signals. heat stress or cold stress (may require work/rest cycles). Only an NCSU employee may be attendant for NCSU employees entering a permit space. Examples of work requiring isolation of steam, water, or other flowable hazard include: Installation, repair, or demolition of system components. Maintain entry permits for at least one year and evaluate entry permits annually. Contains or has a reasonable potential to contain a hazardous atmosphere, or, Contains a material that has the potential for engulfing an entrant, or, Has an internal configuration such that an entrant could be trapped or asphyxiated by inwardly converging walls or by a floor which slopes downward and tapers to a smaller cross-section, or. Consider using GFCI protection, explosion proof, or intrinsically safe equipment, if necessary. In order to ensure the space is safe for entry, the listed conditions must be met prior to entry. Hydrogen sulfide limit is 5 PPM instead of 10 PPM. Inform the contractor in writing that the workplace contains permit spaces. Note: Lockout or tagout of equipment controlling fluid flowing through pipes, lines, or ducts is not isolation.

Note: Any confined space with metal that oxidizes, such as iron, is initially considered a permit space because of the potential presence of oxygen deficiency. Assist supervisors and entry personnel in confined space hazard assessments, use of confined space entry procedures, including use of PPE. % Individuals can hand off roles to other individuals as long as there is always an entrant, entry supervisor, and a separate person serving as attendant.
