A Confined Space means a space that

Is large enough and so configured that an
employee can bodily enter and perform assigned
work and
Has limited or restricted means of entry and
Is not designed for continuous employee occupancy

8
Permit Required Confined Space (PRCS)

Is a confined space that has one or more of the
following characteristics
Contains, or has a potential to contain, a
hazardous atmosphere
Contains a material that has a potential for
engulfing an entrant

Has an internal configuration such that an
entrant could be trapped or asphyxiated by
inwardly converging walls or by a floor which
slopes and tapers to a smaller cross section
Contains any other recognized serious safety or
health hazard

10
Non-Permit Confined Space

Is a space that does not contain or, with respect
to atmospheric hazards, have the potential to
contain any hazard capable of causing death or
serious physical harm

Definitionsto aid in understanding the OSHA
regulations...
21
Qualified (Competent) Person

A person designated by the Employer in writing,
as capable (by education and /or specialized
training) of anticipating, recognizing and
evaluating employee exposure to hazardous
substances or other unsafe conditions in a
Confined Space
This person shall be capable of specifying
necessary control and/or protective action to
insure worker safety.

22
Attendant

A trained individual, stationed outside the
Confined Space area who monitors authorized
entrants working in Permit-Required Confined
Spaces

23
Authorized Entrant

A trained individual who is authorized to enter a
Permit-Required Confined Space area to perform
work

24
Entry Supervisor

A trained individual who verifies that all
requirements for Permit-Required Confined Space
Entry have been met, authorizing and overseeing
entry operations, and for terminating entries

25
For every entry into a PRCS you will need

At least one attendant
At least one entrant
An entry supervisor
(although the entry supervisor does not need to
remain on site)

26
Hazardous Atmosphere

An atmosphere that may expose employees to the
risk of death, incapacitation, impairment of
ability to self-rescue (that is, escape unaided
from a permit space), injury or acute illness
from one or more of the following

Flammable gas, vapor, or mist in excess of 10 of
its Lower Flammable Limits (LFL)
Airborne combustible dust at a concentration that
meets or exceeds its (LFL)
Oxygen concentration below 19.5 or above 23.5

Concentration of any substance published in
Subpart G, Occupational Health and Environmental
Control, or Subpart Z, Toxic and Hazardous
Substances, in access of its dose or Permissible
Exposure Limits (PEL)
Note A concentration of any substance that is
capable of causing death, incapacitation or
impairment of ability to self-rescue, injury, or
acute illness due to health effects is not
covered by this provision

Any other atmospheric condition that is
Immediately Dangerous to Life and Health (IDLH)

30
Engulfment

The surrounding and effective capture of a person
by a liquid or finely divided (flowable) solid
substance that can be aspirated to cause death by
filling or plugging the respiratory system, or
that can exert enough force on the body to cause
death by strangulation, constriction, or crushing

31
Immediately Dangerous to Life and Health (IDLH)
Any condition that

Poses an immediate or delayed threat to life
Would cause irreversible adverse health effects
Would interfere with an individuals ability to
escape unaided from a permit space

32
Oxygen Deficient Atmosphere

An atmosphere containing less than 19.5 percent
by oxygen by volume

33
Oxygen Enriched Atmospheres

An atmosphere containing more than 23.5 oxygen
by volume

34
Inerting

Displacement of the atmosphere in a permit space
by a noncombustible gas (such as nitrogen) to
such an extent that the resulting atmosphere is
noncombustible

35
Isolation

The process by which a permit required confined
space is removed from service and completely
protected against the release of energy and/or
material into the confined space by such means
as
Blanking and bleeding
Removing sections of lines, pipes or ducts
Double block and bleed
Lock-out, tag-out, or tryout of all sources of
energy
Blocking or disconnecting of all linkages

36
Retrieval System

The equipment including a retrieval line, class
III harness, wristlets, if appropriate, and
lifting device) used for non-entry rescue of
workers from a permit-required confined space

37
Acceptable Entry Conditions

The condition that must exist in a confined space
to allow entry and ensure that employees involved
with a permit-required confined space entry can
work within the confined space safely

38
Entry

The action by which a person passes through an
opening into a permit required confined space,
and includes ensuing work activities in that
space
Considered to have occurred as soon as any part
of the entrants body breaks the plane of an
opening into the space

39
Entry Permit

The written or printed document provided by the
Authority Having Jurisdiction (AHJ) to allow and
control entry to a permit space

40
A permit is simply a checklist

Not issued by the Federal, State or Local
government
Minimum contents set by OSHA
Many formats

41
Content of each permit is based on the AHJs
identification and evaluation of each hazard of
that permit space, or class of spaces, and all
procedures the AHJs requires for protecting
entrants from those hazards during entry.

Each permit contains the information specified in
paragraph (f), ("ENTRY PERMIT") of the standard

42
Prohibited Condition

Any condition in a permit space that is not
allowed by the permit during the period when
entry is authorized

43
Requirements

General

44
The Employer will decide if the workplace
contains Permit Required Confined Spaces (PRCS)
45
If workplace contains Permit Required Confined
Spaces, the Employer must inform employees of
their existence, location and dangers
46
If the Employer decides employees will enter
permit spaces, the Employer shall develop and
implement a written entry program
47
The Employer may use alternate entry procedures
provided certain conditions and requirements are
met
48
When there are changes in use of configuration of
a non-permit confined space that might increase
the hazards to entrants, the Employer shall, if
necessary, reclassify as a permit space
49
If there are no actual or potential atmospheric
hazards and if all hazards within the space are
eliminated without entry, space may be
reclassified for as long as the non-atmospheric
hazards remain eliminated
50
If entry into a confined space is required to
eliminate hazards, it shall be according to
regulations and the confined space may be
reclassified for as long as the hazards remain
eliminated
51
The Entry Supervisor shall certify in writing
that all hazards in Permit Required Confined
Space have been eliminated and make this document
available to each entrant
52
If hazards arise in Alternate Entry Permit Space
or Non-Permitted Space, employees shall exit the
Confined Space and the Entry Supervisor shall
determine whether to reclassify the Confined Space
53
When the Employer arranges for contractor to
perform Permit Required Confined Space entry
work, the Employer shall
54

Inform contractor of the Employer's Permit
Required Confined Space Entry Program
Apprise contractor of particular PRCS hazards,
precautions and procedures implemented for
protection of employees in or near the Permitted
Spaces
Coordinate entry operations with contractor when
both will be working in or near Permitted Spaces
and debrief contractor after entries

55
Contractors shall comply with the Employers
Permit Required Confined Space Entry Program
during combined employee entries and coordinate
multiple entry operations

59
A confined space entered using Alternate Entry
Procedures may not have any hazard until after
the space is vacated
60
Major utility companies often use alternate entry
procedures
61

ventilation

Entry will not be permitted until hazardous
atmosphere is eliminated.
Ventilation shall be directed to immediate areas
where employees are or will be present and shall
continue until employees have left space.
Air supply shall be from a clean source and may
not increase hazards in space.
Atmosphere within space shall be continuously
tested.

62
Procedures when a hazardous atmosphere is
detected during entry

Each employee shall leave the confined space
immediately
Permit Space shall be evaluated to determine how
hazardous atmosphere developed
Measures shall be taken to protect employees from
the hazardous atmosphere before a subsequent entry

The Entry Supervisor shall certify in writing
that the confined space is safe for entry and
that all of the above requirements have been met
The Entry Permit will be available to each
employee before entry

139
SHOULD USE TWO MONITORS

When your alarm goes off - believe it

140
Testing must be continuous for the outside and
inside of the Confined Space

This makes sure that old problems don't reoccur
and new ones don't arise

141
(No Transcript)
142
Use meter to check air quality.

Monitor air outside space first.
Monitor air at confined space entry point second.
Monitor air inside entry point third.
Monitor air at half-way point (half-way between
entry point and farthest point inside confined
space) fourth.
Monitor air at farthest point (where victim is
located) last.

143
Use of ventilation to control the situation
144
Definition

The planned and systematic release and removal of
gases and the replacement of these gases with a
supply of fresh air
The same objective as at a structure fire

145
Consider characteristics of gases

Vapor densities
Stratification

146
Reasons for ventilation

When the type of construction is unsuitable for
natural ventilation
To remove dangerous gases
To reduce LEL's to safe levels
To produce a work environment with a temperature
conducive to human habitation

147
When to ventilate

Prior to and during entry of confined space

148
Where to ventilate

In the area where the confined space is occupied
During a rescue, the ventilation hose should be
directed at the victims face when possible

149
Ventilation must be continuous
150
Ventilation equipment should be intrinsically
safe if dealing with flammable gases
151
Tubing should be sized so escape air can be
released around it from the opening
152
Use upwind
153
Area outside the Confined Space should be clear
for dangerous expelled gases
154
Make sure you're not purging your Confined Space
with contaminated air from the outside

Car exhaust, small engine exhaust

155
An exhaust mode can draw flammable gases into
your equipment and BOOM!
Always operate the ventilator in the positive
pressure mode
156
How long to ventilate?

Until the confined space is free of toxic gases
and the LEL is at a safe level
MONITOR
Minimum of 5 minutes or
6 air exchanges in the space
Blower should be operated for one minute prior to
putting hose in confined space

157
Blower considerations

CFM (usually stamped on blower)
The length of blower hose and the number of bends
will affect the CFM achieved
Tubing in hole should not obstruct exhaust gases,
should allow one person to enter and exit
The blower should not be closer than 5 feet to
confined space opening

158
Placement of blower hose

In a vertical confined space with a 90 degree
bend, blow against the wall, at least one foot
below the surface, and two feet above the floor
In a horizontal confined space lay hose on the
floor with the end of the hose at least two feet
from the end wall. Be sure blower is out of the
path of the purged air
