List of Confined Spaces

• Silo
• Manhole
• Tank spill containment
• Etc..

7
Requirements of the Standard

• Employers must evaluate the workplace to
  determine if spaces are permit required confined
  spaces. (consult chart)
• Employer must inform employees.
• Written Program.
• Permit System.
• Training and Education

8
Requirements, continued

• Equipment
• 1. Testing and Monitoring
• 2. Rescue
• 3. PPE
• 4. Communications
• 5. Ventilating

9
Requirements, continued

• Contractor requirements
• 1. Inform of rules and hazards.
• 2. Equipment.

10
SIX STEPS TO SAFE CONFINED SPACE ENTRY

• Identify the Space
• Permit the Space
• Isolate the Space
• Ventilate the Space
• Test the Space
• Equip the Space

11
ID the SPACE

• Is it a Confined Space?
• Permit or Non-Permit?

12
PERMIT the SPACE

• Follow Permit Guidelines (see permit)
• Names and Signatures of Team
• Name and Signature of Supervisor

13
ISOLATE the SPACE

• DE-ENERGIZE (mechanical, pneumatic, hydraulic,
  gravity, pressure, etc.)
• BIG FIVE PROCEDURES
• 1- Permit 2- Hot Work
• 3- LOTO 4- Confined Space
  Entry
• 5- Linebreak (Purge)

14
VENTILATE the SPACE

• Mechanical Ventilation before and after Testing
• During Entry

15
TEST the SPACE

• Monitor for Oxygen (19.5-23.5)
• Monitor for LEL
• Test for other Contaminants
• Test at ALL LEVELS!

16
EQUIP the SPACE

• Permits should list all equipment and tools
  necessary for Entry and Rescue

17
SUMMARY

• OSHA has a CS Standard because of the continuing
  fatalities in confined spaces. The biggest
  killer involving confined spaces is lack of
  knowledge. Education, a written plan, and
  enforcement of rules can eliminate confined space
  fatalities.
