Confined Space Entry:

This publication discusses those hazards, safe entry procedures and rescue associated with confined space entry. Its intent is educational, preventive and fulfills the requirements of the OSHA Confined Space Entry Written Control Plan, 29 CFR 1910.146. Click here to reference the document. A copy of this written program shall be available to any University employee upon request. With these procedures, persons working in confined spaces should always exit alive and unharmed. You may also view the the Confined Space Entry Written Program adopted by the University of Tennessee.  Click here

The hazards that may be present in a confined space are not easily seen, smelled, heard or felt, but can represent deadly risks. The worker who enters confined spaces may be, or often is, exposed to multiple hazards due primarily to ignorance or negligence in the enforcement of safety regulations. This ignorance and neglect has led to countless deaths by asphyxiation, fire and/or explosion, and by fatal exposure to toxic materials.

A permit-required confined space is one in which dangerous air contaminants may be generated and may not be removed by ventilation. When an employee works in this type of environment, the chance exists that atmospheres present may be oxygen deficient, combustible or toxic. Prevention of injuries to the life and health of workers requires that they be properly trained and well equipped to recognize, understand and control the hazards they could encounter. In the process of identifying a confined space, the supervisor in charge should always assume that a hazard is present.
