means the minimum concentration of a substance flammable limit or lower explosive limit in air needed for an ignition source to cause a flame or explosion. the process used to identify and evaluate the hazards after an Monitor or monitoring authorized entrant enters the space. This is a process of checking for changes that is performed in a periodic or continuous manner after the completion of the initial testing or evaluation of that space. occurs when a rescue service, usually the attendant, retrieves employees in a rescue permit space without entering the permit space. means a confined space that meets the definition of a confined space Non-permit confined space but does not meet the requirements for a permit-required confined space, as defined in this subpart. an atmosphere containing less than 19.5 percent oxygen by Oxygen deficient atmosphere volume. an atmosphere containing more than 23.5 percent oxygen by Oxygen enriched atmosphere volume. (permit space) means a confined space that has one or more of Permit-required confined space the following characteristics: Contains or has a potential to contain a hazardous atmosphere; Contains a material that has the potential for engulfing an entrant; 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 crosssection; or Contains any other recognized serious safety or health hazard. (permit space program) means the employer's overall Permit-required confined program program for controlling, and, where appropriate, for protecting employees from, permit space hazards and for regulating employee entry into permit spaces. means an existing or potential hazard that can cause death or serious physical Physical hazard damage. Examples include, but are not limited to: Explosives (as defined by paragraph (n) of § 1926.914, definition of "explosive"); mechanical, electrical, hydraulic and pneumatic energy; radiation; temperature extremes; engulfment; noise; and inwardly converging surfaces. Physical hazard also includes chemicals that can cause death or serious physical damage through skin or eye contact (rather than through inhalation).
