Permit Required Confined Spaces

The following lists identify permitted, (areas requiring a permit to enter), and nonpermitted, (areas not requiring a permit to enter), spaces that employees and contractors are allowed to enter.

Non - Permit Required Confined Spaces

The following is a list of NON - PERMIT REQUIRED CONFINED SPACES and is limited to these locations. A non-permit required confined space may become a permit required confined space if conditions of the space change (i.e. performing hot work, introducing chemical in the space, and other conditions).

• Electrical Rooms - that a person may enter through a regular 80" high door way designed for people.
• Machinery - Vent Rooms (i.e. filter banks)
• Steam Tunnels/(Utility Tunnels) - that a person may enter through a non restricted entrance and that a person may move about without restriction.
• A non-permit required space must have periodic surveillance of air quality and quantity by the Physical Plant for the designation of non-permit required confined space to exist

Permit - Required Confined Space Physical Characteristics

A permit required confined space is a space that has limited means of egress, (and/or) not designed for continuous employee occupancy, (and/or) having one or more of the following characteristics:

1. Less than 19.5% oxygen and not over 23.5%.
2. Flammable/combustible/explosive atmospheres present or able to be generated or to enter into an area. % OF L.E.L = over 10%
3. Toxic atmospheres present or able to be generated or to enter into an area.
   
   P.E.L.
   
   Carbon Monoxide = 50 ppm
   Aromatic Hydrocarbon = 10 ppm
   Hydrocyanic Acid = 10 ppm
   Hydrogen Sulfide = 10 ppm
   Sulfur Dioxide = 5 ppm
   Ammonia = 25 ppm
4. Areas not protected against entry of water, gas, sand, gravel, ore, grain, coal, biological, radiation, corrosive chemicals, or any other substance which could possibly trap, suffocate, or harm a person.
5. Poor ventilation
6. Restricts entry for rescue purposes.
7. An open - topped space over 4 feet deep.

Hazard Identification

The hazard that may exist or develop during entry of a confined space include:

• Oxygen deficient atmospheres Corrosive Materials
• Toxic atmospheres Hot equipment
• Engulfed or buried Toxic Materials
• Electrocuted Drains Open
• Fire and/or explosives Cleaning(chemical or water lance)
• Drowning Spark Producing Operations
• Falls Spiller Liquids
• Crushed or Mangled Pressure Liquids
• Exposure to harmful chemicals
