EP8HL HAZARDOUS BLOWER
FORM GOM7069501, VERSION 1.2

CONFINED SPACE REGULATION DISCLAIMER.

Before  operating  the  Blower,  obtain  a  copy  of
OSHA  Standard  29  CFR  1910.146  and/or  current
revision. This standard provides a comprehensive
regulatory  framework  by  which  employers  can
effectively  protect  employees  who  work  in
confined work spaces. 
BASIC 

INFORMATION 

AND 

DEFINITIONS

PERTAINING 

TO 

CONFINED 

SPACE

REGULATIONS.

Many confined work places contain spaces which are
considered  "confined"  because  their  configurations
hinder  the  activities  of  any  workers  who  must  enter,
work in or exit them. For example, employees working
in process vessels generally must squeeze in and out
through narrow openings and perform their tasks while
cramped  or  contorted.  In  addition  there  are  many
instances  where  employees  who  are  working  in
confined  work  spaces  also  face  increased  risk  of
exposure  to  serious  hazards.  In  some  cases,
confinement itself poses entrapment hazards. In other
cases  confined  space  work  keeps  workers  closer  to
hazards  such  as  asphyxiating  atmospheres  or  the
moving parts of a mixer, than they would be otherwise.

Accordingly, under the regulation, OSHA distinguishes
between  confined  work  spaces  that  pose  a  threat  of
death  or  serious  bodily  harm  and  those  that  pose  no
such  threat---existing  or  potential.  This  distinction  is
accomplished  through  a  series  of  three  definitions
essential to the application of the standard. The first is
defined as follows:

1) The space is large enough and so configured that a
worker can bodily enter and perform assigned work.

2) The space has limited or restricted means for entry
or exit.

3)  The  space  is  not  designed  for  continuous  worker
occupancy. 29 CFR 1910.146(d).

The term "non permit required confined work space" is
defined  in  the  standard  as  follows:  "a  confined  space
that  does  not  contain  or  with  respect  to  atmospheric
hazards  have  the  potential  to  contain  any  hazard

capable  of  causing  death  or  serious  harm.  29  CFR
1910.146(b).

The  term  "permit  required  confined  space"  means  a
confined  space  that  presents  or  has  a  potential  to
present one or more of the following:

1) An atmospheric hazard.

2) An engulfment hazard.

3) A configuration hazard.

4)  Any  other  recognized  serious  hazard.  29  CFR
1910.146(b).
Under  29  CFR  1910.146(c)(1),  the  employer  shall
evaluate  the  workplace  to  determine  if  any  spaces
require a permit to enter. If the work space requires a
permit,  then  29  CFR  1910.146(c)(2)  requires  the
employer to inform exposed workers of such dangers
by posting signs or any other equally effective method
or means to communicate the potential dangers. If the
employer  decides  its  employees  will  not  enter  a
confined work space requiring a permit, he must follow
the protocol found in 29 CFR 1910.146(1), (2), (3), (6)
and (8).

If workers will enter a confined work space requiring a
permit, then the employer shall develop and implement
a  written  permit  confined  work  space  entry  program
found in 29 CFR 1910.146(d).
