Confined Space
  • The three criteria that define a confined space are:
    • - Big enough to get inside of
    • - Restricted means of entry and exit
    • - Not designed for continuous occupancy
  • A Permit Required Confined Space meets the above criteria and poses some type of hazard to people. Common examples are steam tunnels (heat), sewer pipes (toxic gases), and silos (combustible dusts or gases). For this type of confined space entry an entry permit form must be filled out and hazard mitigation and monitoring must be conducted before and during the confined space entry.
  • Longwood University Confined Space Procedure

At Longwood University some of the areas that our employees enter to do maintenance are considered to be confined spaces because their configurations hinder the activities for employees who must enter into, work in and exit from them. In many instances, employees who work in confined spaces also face increased risk of exposure to serious physical injury from hazards such as entrapment, engulfment or hazardous atmospheres. Being in tight quarters itself may pose entrapment hazards, work in confined spaces may keep employees closer to hazards, such as machinery components, than they would otherwise be.  In other words, tight quarters, limited access and restricted airflow can result in hazardous conditions that would not normally arise in an open workplace.  The term “Permit Required Confined Space” refers to those locations that meet the definition of a confined space and also contain health or safety hazards, thereby requiring a permit for entry.


A Confined Space has;

  1. Limited or restricted means of entry or exit,
  2. Is large enough for and employee to enter and perform assigned work, and
  3. Is not designed for continuous occupancy by the employee.

A Permit Required Confined Space is one that meets the definition of a confined space and has one or more of the following characteristics:

  1. Contains or has the potential to contain a hazardous atmosphere.
  2. Contains a material that has the potential for engulfing and entrant.
  3. Has and internal configuration that might cause an entrant to be trapped or asphyxiated by inwardly converging walls or by a floor that slopes downward and tapers to a smaller cross section.
  4. Contains any other recognized serious safety or health hazard.

Longwood University’s Confined Space Program is based on OSHA standard 1910.146 Permit Required Confined Space and the Virginia VAOSHA standard 16VAC25-70-10 et seq Virginia Confined Space Standard For The Telecommunication Industry (1910.268(t)).

The program describes the reasonable and necessary policies and procedures for any and all Longwood University operations that are associated with confined space entry operations.

Individuals’ covered by this program are employees whose job duties involve one or more of the following activities are included:

  • Perform actual entries into permit-required confined spaces (Authorized Entrants)
  • Serve as an attendant during the permit-required confined space entry (Attendant)
  • Supervise others who enter or attend during entries (Entry Supervisor)

No one may serve in any of these capacities without first receiving Confined Space Entry training.

The program addresses:

  • Confined Spaces at Longwood University
  • Confined Space Flow Chart
  • Confined Space Assessment
  • Confined Space Profile
  • Permit Space Temporary Reclassification
  • Permit Required Confined Space Entry
  • Alternate Entry
  • Non-Permit Required Confined Space Entry
