TRANSCRIPT
Why this training? 1. Confined space can contain gases or a lack of
oxygen that can harm you or be fatal.
2. Follow proper safety procedures.
3. If you don’t know how, then don’t do it!4. Always asks yourself, what am I working with,
how can it hurt me, what do I need to do to protect myself?
5. NEVER ENTER A CONFINED SPACE before first checking for hazardous atmosphere!
Learning ObjectivesBy the end of this training you should be able to answer the following questions:
1.What is a confined space? What hazards exist in a confined space?
2.What is a confined space entry permit? When is it used? How do I use a 4‐gas meter?
3.What engineering controls can be used?
4.What personal protection equipment needs to be used?
What is a confined space?California Code of Regulations (CCR), Title 8, Section 5156(b), 5157 and 5158.
• Prevent employee exposure to confined space hazards in silos, tanks, vats, vessels, boilers, compartments, ducts, sewers, pipelines, vaults, bins, tubs, and pits.
• Trenches and excavations are considered potential confined spaces by Cal/OSHA.
What is a confined space? (Part 2)Confined space means a space that:• Is large enough and so configured that
an employee can bodily enter and perform work: and
• Has limited or restricted means of entry or exit; and
• Is not designed for continuous employee occupancy.
What is a confined space? (Part 3)A space defined by the existence of the following conditions:• Existing ventilation is insufficient to remove
dangerous air contamination, oxygen enrichment and/or oxygen deficiency which may exist or develop.
• Access or egress for the removal of a suddenly disabled employee is difficult due to the location and/or size of the opening(s).
What is a confined space? (Part 4)Section 5158 also states:
• The employer shall implement training before any employee is permitted to enter a confined space. Including required standby persons.
• The air shall be tested with an appropriate device determine whether dangerous air contamination, oxygen enrichment and/or an oxygen deficiency exists. A written record of testing results shall be made and kept.
What hazards exist in confined spaces?
• Lack of breathable oxygen or to rich an oxygen environment.
• Methane gas (flammable/explosive).
• Hydrogen sulfide gas. Odorless, invisible, called instant death.
• Carbon Monoxide gas. Odorless, invisible, called sleeping death.
Don Chapin Company Safety Policy
NEVER enter a confined space without first testing for the presence of dangerous gases
or oxygen deficient atmosphere!
Example of Confined Space Hazard #1
Applying waterproofing to the interior of tanks, Henry’S HE101, chemical fume.
Example of Confined Space Hazard #2
Active storm drain and sewer, manholes and pipelines, can contain hydrogen sulfide and
methane gas or oxygen deficiency.
Example of Confined Space Hazard #3
Septic tank inspection and repair have methane and hydrogen sulfide gases.
Example of Confined Space Hazard #7
Carbon monoxide poisoning from gas powered equipment operated in trenches.
Example of Confined Space Hazard 9
Use of chemical coatings or solvents inside box culvert structures
Is this a confined space hazard?
Yes!Operating gas powered tools without ventilation
will create a carbon monoxide hazard .
What is the entry permit?
Entry permit means the written or printed document that is provided by the employer to allow and control entry into a permit space and that contains the information specified (see DCCI entry‐permit form)
When is the entry permit used?
Always, when ever a potential hazard exists to an employee.Note, Title 8, Section 5157 does provide for the reclassification to a non‐permit confined space (This only applies under specific conditions).
How do I use a 4‐gas meter?4‐gas meter detect hazardous atmospheres.
Lack of oxygen (O2)
Oxygen rich environment
Lower explosive limit (LEL)
Hydrogen Sulfide (H2S)
Carbon Monoxide (CO)RKI Instruments RX‐2009/RP‐2009
What engineering controls can be used?
Mechanical ventilation is used in confined spaces to supply fresh air and disperse contaminants
