Your Challenge

1)Use the SCORE CARD provided as a guide to the presentation.

2)Make an honest evaluation of your understanding of the topics discussed.

3) Focus your organization’s “improvements” on the issues scored “ UNCOMFORTABLE ”.

The three conditions that define a confined space…

1 . Large enough to enter,

2. Limited means of access

3. Not designed for continuous occupancy

What must an employer develop as part of their Confined Space

Entry program…

An inventory of all spaces including the hazards, space classifications, equipment requirements, and rescue procedures

Challenge #1

Can your employees identify a Confined

Space (CS)?

Whenever possible confined spaces should be identified using this method…

Space – Entry by Permit Only –

CONFINED SPACE

Considered to be the most common and dangerous hazard in a confined space…

“Atmosphere”

If a confined space has an oxygen atmosphere between

_____% and _____ %, it may be safe to enter.

“19.5% - 23.5%”

Atmospheric monitors display flammability as a percentage of this measurement…

“Lower Explosive Limit or

LEL”

Challenge #2

Are there procedures and supervision in place to test the atmosphere prior to, and during, every

Confined Space Entry

(CSE)?

Lake Hemet Water District CSE

Fatality

Other than atmosphere, name four other hazards may one face in a confined space…..

“Engulfment, internal configuration, or job introduced hazards such as electrical, moving parts, pressure piping, welding, chemicals,….”

The frequency with which gas monitors need to be calibrated…

“According to the manufacturer’s recommendations”

Appendix B of the Cal/OSHA confined space regulation states that the atmosphere should be tested every 4 feet because the potential for…

“Stratification” or

“Layering”

Gas Stratification in Confined

Spaces

Floats

CHECK

Drifts

ALL

LEVELS

Sinks

The primary means of control used to maintain safe atmospheric conditions…

“Mechanical Ventilation”

Space Ventilation

WIND WIND

POSITIVE PRESSURE

One opening

Lighter than air gases

NEGATIVE PRESSURE

One opening

Heavier than air gases

This happens when ventilation air moves directly from the inlet to the exhaust outlet, without reaching the other areas of the space…

“ Short-Circuiting”

Space Ventilation

WIND WIND

SHORT CIRCUTING

Hose too short Air turns to path of least resistance

RECIRCULATING

Fan intake in downwind

Hazardous air is drawn into fan

Challenge #3

Do your employees know how atmospheric control equipment works?

The three types of confined space entries that may be performed…

“Permit Required Entry”

“Alternate Procedure “C(5)” Entry “

“Declassified / Non-Permit Required

Entry”

Which of the three types of confined spaces require atmospheric testing prior to entry?

“ALL OF THEM!”

The confined space regulation states that an entry supervisor must complete this document before anyone enters a confined space…

“Confined Space Permit”

Challenge #4

Can your employees determine the proper classification of a confined space?

The four duty positions required by Cal/OSHA for a

Permit-Required confined space entry…

Entrant, Attendant,

Supervisor, Rescue

What every confined space position must know prior to an entry being made?

The hazards and how to control or eliminate them

Confined space entry has occurred when any part of the body…

“Breaks the plane of a space”

The action that must be taken if the attendant leaves the space…

“Personnel must exit the space”

The person who has overall responsibility for the entry…

“Entry Supervisor”

Who has the obligation to inform outside contractors about all known hazards and precautions normally taken when entering a confined space….

“Host Contractor/Host

Agency”

Challenge #5

Is your staff adequately trained for CSE operations?

In the past, 50-60 % of fatalities in confined spaces were these types of persons…

“Would be rescuers”?

List at least five pieces of rescue equipment you would want to have available…

“Tripod, Harness, Winch,

Gas Monitor, Ventilator,

SCBA, Annual Training….”

Rescue teams must conduct a training drill at least once every…

“12 months”

Challenge #6

Do you, without a doubt , have a rescue capability for every

CSE?

Thank you for taking the
