1Confined Space Training
- Permit-Required Confined Spaces
- Title 8 Sections 5156-5159
2Confined Space Statistics
- Leading cause of occupational fatalities in this
country - The Standard covers 240,000 workplaces and 12.2
million workers - Workers make 4.8 million entries/year
- Standard may prevent 85 of fatalities and
nearly 11,000 injuries
3Definition of a Confined Space(must meet all
three criteria)
- Limited means for entry or exit (manholes,
vaults, pits) - Large enough so configured that an employee can
bodily enter and - perform assigned work
- Not designed for continuous occupancy
- Two types Permit Non-Permit Required Spaces
4Definition of Permit-RequiredConfined Spaces
- A confined space that has one or more of the
following characteristics - Contains or has potential to contain a hazardous
atmosphere - Potential for engulfment
- Internal configuration that can trap or
asphyxiate entrant - Any other serious safety or health hazards
(electrical, hot work, drowning . . .)
5What is a Hazardous Atmosphere?
- An atmosphere that may expose employees to the
risk of death, incapacitation, impairment of
ability to self-rescue, or acute illness
resulting from the following - Flammable gas, vapor or mist in excess of 10 of
the LFL - Combustible dust at a concentration that is gt or
LFL - Oxygen concentration lt 19.5 or gt 23.5
- Any substance with concentration gt PEL
- Any other atmospheric concentration that is IDLH
6Permit-Required Spaces on Campus
- Electrical vaults electrical hazards, low
oxygen, /or asbestos - Sewer manholes CO, low oxygen,
- /or toxic gases
- Storm drain manholes
- CO, low oxygen, /or toxic gases
7Permit-Required Spaces on Campus (cont)
- Pool Pit lack of oxygen, toxic gases,
- /or drowning
- Sewer Tanks toxic gases, low oxygen,
- drowning, /or electrocution hazards
- Communication Vaults low
- oxygen, asbestos,
- /or electrical hazards
8Non-Permit Required Spaces
- Spaces that do not contain or, with respect to
atmospheric hazards, have the potential to
contain any hazard capable of causing death or
serious physical harm - Utility closets
- Below-grade trenches
- Storage vaults
- Utility subbasements
9Confined Spaces on Campus
- EHS and PPM jointly determine which types of
spaces or specific spaces are defined as confined
spaces - All confined spaces on campus will be considered
Permit Required until pre-entry procedures
determine otherwise. - Only the Entry Supervisor is authorized to
downgrade entry requirements.
10Confined Space Entry Procedures
- Space Evaluation
- Alternate Entry Procedures
- Permit-Required Entry Procedures
11Space Evaluation
- Refer to Flow Chart
- Entry Supervisor must evaluate authorize an
entry - This will determine if Alternate Entry or
Permit-Required - If the space is reclassified as an Alternate
Entry then the following conditions must exist - only hazard is the potential for a hazardous
atmosphere and - potential hazard can be eliminated through
continued forced - air ventilation and
- previous current gas tests must show above two
conditions are true
12(No Transcript)
13Alternate Entry Procedures
- Procedure that may be used to enter a confined
space if the only hazard present in the space is
atmospheric in nature and - The atmospheric hazard can be controlled by
mechanical ventilation alone and - The permit space will not become immediately
dangerous to life and health (IDLH) if the
mechanical ventilation should fail.
14Alternate Entry Procedures (cont)
- Entry Supervisor ensures space has been properly
classified - Use guarding/cover/barrier to prevent
- falls (when removing cover)
- Lock out/tag out all hazardous
- energy sources
- Complete log
- Test for O2, flammable gases/vapors and potential
toxic air contaminants - Set up ventilation (supply air taken from clean
source) - The Entrant will evacuate the confined space if
he/she becomes aware of an unrecognized hazard

17Permit Required Entry Procedures
- Entry Supervisor, Entry Attendant and Entrant
must participate - Inspect and setup safety equipment
- Entry Supervisor establishes specific rescue
procedures - Lock and tag out all hazardous sources of energy
- Use guarding If removing an entrance cover
- Sample and record air for hazardous contaminants
- Entry Supervisor completes Permit prior to entry
18Permit Required Entry Procedures (cont)
- Attendant verifies acceptable entry conditions
- Entrant wears retrieval equipment during entire
operation - Attendant continuously monitors atmosphere
records readings with the portable gas detector - Immediately evacuate space if safety equipment
fails or space becomes or has potential to become
immediately hazardous - Upon completion, Entry Supervisor completes
permit and files
19Potential Confined Space Hazards
- Engulfment
- Oxygen deficiency (19.5 or less)
- Oxygen enrichment (23.5 or higher)
- Flammable gases or vapors
- Combustible dusts
- Toxic substances
- IDLH atmospheres
- Physical hazards
20Monitoring Confined Space Air Quality
- Prior to entering any confined space, prepare the
gas detector - Conduct a bump test. Breathe into the gas
detector probe and look for a decrease in oxygen
concentration - should alarm - Sample air quality by slightly removing lid or
through hole in lid before completely opening the
space - Monitor with probe slowly at different vertical
heights - Measure in the following order
- Oxygen, LEL, H2S, CO
- Record results on the Confined Space Entry Permit
Record Sheet
21Monitoring Confined Space Air Quality (cont.)
- The gas detector must be on during the ENTIRE
entry operation - Will be regularly inspected by the Attendant.
- Record gas readings at a minimum of one hour
intervals - Cease entry operations and remove entry personnel
if the following concentrations are exceeded at
any time - Oxygen reading less than 19.5 or greater than
22.5 - Combustible gas reading greater than 9 LEL
- H2S reading greater than 9 ppm
- CO reading greater than 34 ppm
22Ventilating a Confined Space
- Set up one or more blowers to
- provide adequate ventilation for
- the space. Ventilation must be
- forced draft discharge of clean air
- into space (not exhaust of space)
- Ensure ventilation air supply is from clean
source - Allow enough time for blowers to clear the space
before entering. - Ensure that the blowers remain on during the
entire entry procedure. If the blower fails, the
Entrant must leave the space immediately - Note this applies to both Permit Required and
Alternate Entry procedures
23Types of Personal Protective Equipment
- Protective clothing
- Welding apron/sleeves
- Respirators
- Gloves
- Safety glasses
24Retrieval Equipment
- Rescue harness (chest or full body)
- Rescue tripod
- Rope or cable (inspect for damage)
25Department Responsibilities
- EHS
- Establish update written program
- provide training
- review records provide consultation
- PPM Communication Services
- Ensure all involved employees receive training
follow procedures - provide and maintain equipment
- maintain records
26Entry Supervisor Responsibilities
- Ensure all persons involved in a confined space
entry are properly trained - Evaluate and classify the confined space prior to
entry - Complete the Confined Space Entry Permit (if
required) - Ensure canceled permits are properly filed
27Entrant Responsibilities
- Completed Confined Space training
- Must stay in constant contact with the Attendant
(I.e. sight, voice, or radio) during a Permit
Required Confined Space entry - Use the appropriate safety equipment as specified
on the Entry Permit
28Entry Attendant Responsibilities
- Completed Confined Space Training
- Obtain install required safety equipment for
Permit Required Confined Space entries - Monitor pedestrian barriers to protect entrant(s)
from external hazards - Monitor the atmosphere during the entire entry
operation - Must remain in position until relieved by another
trained Attendant - Ensure all lockout/tagout measures (if
implemented) remain in place - Responsible for ordering an evacuation if a
situation develops that could endanger the Entrant
29Rescuer Responsibilities
- Understand the hazards of the space
- All rescues attempted by CSUN personnel will be
Non-Entry Rescues (i.e. rescuer will not enter
the space at any time during rescue) - Retrieval equipment is required for all Permit
Required vertical entries greater than 5 feet - Be certified in emergency first aid and CPR
- Entry Supervisor must determine how emergency
personnel will be notified - Understand appropriate entry procedures
- Know how to use rescue equipment
- Practice confined space rescues at least annually
30Training
- All Campus employees who participate in Permit
Required or Alternate Entry Procedures including
Entrance Supervisors, Attendants, and Entrants,
must receive training in the requirements of this
program - All Campus employees who are designated as rescue
personnel must be trained in proper rescue
techniques as well as CPR and First Aid
31REMEMBER . . .
- Call EHS if area is questionable
- 99 of entries are alternate entry
- The campus has changed over time, and is still
changing, so dont rely on past history - Use the decision flow chart each time!
- Only the Entry Supervisor may downgrade
- All rescues are non-entry
- Be safe!
