Non Permit Confined Space

Non permit confined spaces must be evaluated when changes occur in their use or configuration and where appropriate must be reclassified as permit spaces.

Non permit confined space. When a certain confined space is called non permit it means that the space does not or could not contain hazards that could cause death or serious harm. These spaces require a comprehensive safety plan and employers should then follow the requirements in osha standard 1910 146. Non permit required confined spaces do not contain additional hazards such as the potential of a hazardous atmosphere or the potential for workers to become engulfed or trapped by materials.

John a non permit required confined space is a standard space such as a utility vault which has the same characteristics from vault to vault. However irrespective of the confined space workers are working in both have to have a comprehensive safety plan set in place. In fact the aforementioned criteria constitute a non permit required confined space.

The agency also classifies confined spaces as either non permit required and permit required. This hazard doesn t hinder workers ability to enter or exit the trench. Non permit confined space means a confined space that does not contain or with respect to atmospheric hazards have the potential to contain any hazard capable of causing death or serious physical harm.
