1.3 Respiratory and Health Alerts
WARNING
TOXIC DUST POISONING
Research by the Occupational Safety and Health
Administration (OSHA) has discovered potential
risks of lead and other heavy metal poisoning to
unprotectedabrasiveblastingoperatorsandother
personnel who may be exposed to toxic dust in
the abrasive blasting vicinity. Toxic dust is pro-
ducedprimarilybytheremovalandbreakdownof
lead or other heavy metal coatings during abra-
sive blasting.
The breakdown of toxic coatings and hazardous
abrasive causes the contaminants to become
airborne. Breathing toxic dust from lead or other
heavy metal coatings may cause health and life
threateningtoxicpoisoningandcandamagevital
organs.Breathinghazardousdustproducedfrom
silica abrasive may cause delayed life threaten-
ing respiratory disease such as silicosis.
Lead is one of several toxic dusts that may be
present in an abrasive blasting operation. It is
imperative that blasting contractors identify all
material being removed by blasting, and obtain
material safety data sheets (MSDS) for the blast-
ingabrasivepriortoblasting.Itistheresponsibil-
ity of the employer to identify all airborne con-
taminantsintheblastvicinity,andensuretheydo
not exceed the permissible exposure limit (PEL)
Ref. 29 CFR 1910.1000 and 29 CFR 1926.62. Thor-
ough examinations should be made by an indus-
trial hygienist or other qualified professional to
identify all contaminants generated by blasting
and in the blasting vicinity.
Exposure to dangerous levels of lead or other
toxic or hazardous dust is not restricted to blast
operators. There may be an equal or greater
dangeraftertheblastingprocessduetolingering
airborne dust particles, and especially from dust
generated during cleanup activity. Heavy metal
paint, asbestos, sand or other silica, and other
toxic material dusts will cause serious lung dis-
ease or death without the use of properly de-
signed, and maintained NIOSH-approved, sup-
plied-air respirator equipment by blasting opera-
tors and all personnel within the work site area.
Leadpoisoningcancausedeath.OSHAhasstated
that the permissible exposure limit of lead is 50
micrograms per cubic meter of air (50 µg/m3),
averaged over an 8-hour workday.
The Apollo supplied-air respirator system is ap-
provedbyNIOSHasaType-CE,continuous-flow,
abrasive blast, supplied-air respirator, in accor-
dancewith title 42CFRPart84.TheNIOSHrecog-
nized assigned protection factor (APF) for any
supplied-air respirator equipped with a loose-
fitting hood or helmet and operated in a continu-
ous flow mode is 25, based upon the NIOSH
Respirator Decision Logic (Pub. No. 87-108). In
other words, any Type-CE respirator should be
used only in atmospheres in which the contami-
nant level does not exceed 25 times the permis-
sible exposure limit. However, in its Memoran-
dum for Regional Administrators dated August
30, 1995, OSHA has stated that select individual
Type-CE continuous-flow, abrasive blast, sup-
plied-air respirator models that pass stringent
tests conducted by independent third party test-
inglaboratorieswillbegrantedAPFvalueshigher
thantheNIOSHrecognized25.Clemcocontracted
with Los Alamos National Laboratory to conduct
the independent testing. Based upon the results
of these tests, OSHA will treat the Apollo Sup-
plied-Air Respirator (NIOSH Approval TC-19C-
339) as having an APF of 1000 times the permis-
sibleexposurelimit,or50,000µg/m3whenusedin
lead removal applications.
The employer must provide and maintain appro-
priateapprovedrespirators,inadditiontoprovid-
ing operator training and employing required
work site safety practices.
To avoid any potential danger of respiratory in-
jury, approved, supplied-air respirators must be
worn at all times in the presence of any type of
dust. The respirator must be maintained as de-
scribed herein. Improper use of any respirator
may cause life threatening respiratory disease,
and immediate poisoning from toxic dust. Respi-
rators should be removed only after the ambient
airhasbeentestedwithadustmonitor,andfound
to be safe to breathe.
Toxic dust poisoning may also occur by eating,
drinking, or smoking in a contaminated area, or
by eating, drinking, or smoking in a non-hazard-
ous area before thorough washing of hands and
face. Do not eat, drink or smoke in the blast area.

APOLLO 20 LP SUPPLIED-AIR RESPIRATOR Page 3
Thoroughly wash hands and face to remove con-
taminants before eating, drinking, or smoking
outside the blast area.
This manual does not contain all the health and
safety requirements regarding toxic and hazard-
ous dust exposure. Obtain copies of the OSHA
regulations and consult a safety professional
and/or industrial hygienist for complete require-
ments.
Within this manual we refer to hazardous or con-
taminatedenvironments.Theseenvironmentscan
be any place around the blast area that could
contain toxic or hazardous dust.
Ifthesewarningsarenotcompletelyunderstood,
or if further information is required, contact a
local OSHA office. If any personnel in the abra-
siveblasting vicinity cannotreador comprehend
these warnings and the entire content of this
instructional material, assign a qualified person
to instruct him/her.

1.5 Special Use Limitations
1.5.1 Air pressure at the point of attachment (the point
of attachment is where the respirator supply hose is
connected to the respirable air source) must be main-
tained between the minimum and maximum pressures as
shown in the table in Section 4.2.2.
WARNING
Failure to maintain the minimum pressure at the
pointofattachmentmayreduceairflowbelowthe
minimum flow required by OSHA. Reduced air
flow may result in ingress of hazardous toxic
dust,subjectingtheusertoimmediatehealthand
lifethreatening poisoningandsubsequent respi-
ratory disease.
1.5.2 Use no more than 3 sections of respirator hose to
obtain a total maximum length of 300 feet as noted in the

1.5.3 The respirator is designed for specific use in
abrasive blasting applications. Do not use in other opera-
tions such as painting or welding.
1.5.4 Do not supply compressed air to this respirator.
Air from compressors poses hazards, especially from
Carbon Monoxide, that are not covered in these instruc-
tions.
1.6 Protection
1.6.1 Assigned Protection Factor (APF): The NIOSH
recognized assigned protection factor for any Type-CE
respirator(theApollorespiratorisaType-CErespirator)is
25 times the permissible exposure limit (PEL). In other
words,CErespiratorsshouldbeusedonlyinatmospheres
in which the contaminant level does not exceed 25 times
thePEL. However,based uponthe resultsofindependent
testing,OSHAwilltreattheApolloSupplied-AirRespirator
ashavinganAPFof1000timesthePELwhenusedinlead
removal applications.
1.6.2 Head: The respirator protects the wearer’s head
and neck from minor impact and from abrasion caused by
rebounding abrasive. However, the respirator does not
meet the requirements for industrial head protection as
stated in ANSI Z89.1-1997.

APOLLO 20 LP SUPPLIED-AIR RESPIRATOR Page 4
1.6.3 Face: The Apollo 20 inner lens meets impact and
penetration requirements under ANSI Z87.1-1989.
1.6.4 Eyes: Apollo respirators do not provide primary
eye protection. Wear approved eye protection with the
respirator.
1.6.5 Hearing:NoisegeneratedbytheApollorespirator
and measured inside the helmet do not exceed 80 deci-
bels. (42 CFR part 84.140) When any exterior noise
causes the internal noise level to exceed 80 decibels, the
user must wear additional hearing protection. A variety of
hearing protectors can be worn with the respirator.
1.7 Description
1.7.1 The Clemco Apollo 20 Supplied-Air Respirator is
approved by the National Institute of Occupational Safety
and Health (NIOSH).
WARNING
OSHA/NIOSH approval applies only when this
supplied-air respirator is used as a complete
system. Do not make any non-approved modifi-
cation, deletion, or substitution. Non-approved
components voids the NIOSH approval and may
permit ingress of toxic and hazardous dust, and
resultintoxic poisoning and respiratory disease.
1.7.2 The respirator comes with a Constant-Flow Con-
nector assembly, that connects the respirator hose to the
breathing tube.
1.7.3 Therespiratorisdesignedforusewithambientair
pumps only, that deliver 6 to 15 cfm within the approved
pressure range as noted in the table in Section 4.2.2.
WARNING
Do not supply compressed air to this respirator.
Air from compressors pose hazards, especially
from carbon monoxide that are not included in
theseinstructions.Compressorsusedforbreath-
ingair require safetyandmonitoringdevicesthat
are not included in these instructions. Using
compressors that are not suitable for breathing
air could result in death. Reference OSHA Regu-
lations 1910.134(d) and 1910.94(6).
1.7.4 High Pressure Conversion Kit: This optional ac-
cessory kit contains parts and instructions to convert the
Apollo 20 LP (respirator for use with ambient air pump), to
Apollo 20 HP (respirator for use with Grade “D” Com-
pressed Air). The kit is listed in Section 10.1.
2.0 INSPECTION
NOTE: A Clemco respirator hose must be used with the
ApolloRespirator.Ifoneisnotavailable,itmustbeordered
from an authorized distributor of Clemco products. Hoses
are not included with respirators, because blast operators

pare the respirator for operation per Section 3.0. See
Figure 1 for a typical arrangement.
3.0 PREPARATION
3.1 Adjust Helmet Suspension per Section 6.1.
3.2 Lens Assembly
WARNING
Never use the respirator without the fixed inner
lens and middle lens in place. The fixed lens
provides support for the window gasket, and the
middle lens compresses the gasket. If the gasket
is not adequately supported and compressed,
leakscan occur whichcould permit entryof toxic
and hazardous dust or abrasive into the helmet.
3.2.1 The lens system is an important part of the respi-
rator assembly. The helmet is supplied with an inner lens,
secured by a thick rubber gasket. Held in place on top of
theinnerlensbythelensframe,arethemiddlelensandup
to three perforated cover lenses.
3.2.2 Checkthat the innerlensis inplace.(See Section
9.1)
3.2.3 The middle lens and perforated cover lenses are
secured to the helmet by the lens frame. The middle lens
will not need to be changed often because it is protected
by perforated cover lenses. As one cover lens becomes
frostedduringblasting,itcanbetornofftoexposethenext
lens. Check that the perforated cover lenses are in place.
(See Section 9.2)
3.3 Belt
3.3.1 Using the spring clip attached to the Constant-
Flow Connector, attach the connector to the belt slide.
3.4 Breathing Tube Assembly
3.4.1 Attach the red end of the breathing tube to the
threaded air inlet fitting at the back of the helmet.
3.4.2 Attach the swivel connector on the black end, to
the Constant-Flow Connector, or alternate air control
device.
WARNING
The red end of the breathing tube must attach to
the helmet, and the black end to the Constant-
Flow Connector. Failure to properly attach the
tube may increase noise levels beyond OSHA
limits.
3.4.3 Use the molded-in handle to carry or hang the
respirator. Never hold, carry or hang the respirator by the
breathing tube. Mishandling the respirator in this manner
may damage the tube or helmet inlet. Any leaks or breaks
in the breathing tube will alter the air flow through the
respirator and affect user’s safety and comfort.
3.5 Respirator Hose
3.5.1 RespiratorhosemustbeNIOSH-approvedClemco
respirator hose. Use one or two 50 foot hose(s), or one to
three100 ft.respirator hoseto produceamaximumof300
feet. Attach the female end of the respirator hose to the
Constant-Flow Connector. Attach the other end of the
respirator hose to an ambient air pump. Refer to table in
Section 4.2.2.
4.0 AIR SUPPLY
WARNING

WARNING
Neverconnectabreathingairlinetoanairsource
that has not been tested for gas and particulate
contamination. The presence of unacceptable
levels of carbon monoxide (CO) or other gases in
the breathing air will cause death to the user.
4.1.2 Breathingairusedtosupplytherespiratormustbe
respirable breathing air and contain no less than 19.5
volume-percent of oxygen. Breathing air shall also meet
the requirements for Grade D or higher quality, as de-
scribedinCompressedGasAssociationCommoditySpeci-
fication pamphlet G-7.1., titled Commodity Specification
For Air, published by Compressed Gas Association Inc.,
Arlington, VA. (42 CFR Chapter 1).
4.1.3 Prior to using the respirator, read the owner’s
manual and all instructions, labels, and warnings relating
to the ambient air pump.
4.1.4 Take precautions to prevent contaminants from
entering through the air pump’s inlet filter. Locate the air
pump’s inlet filter away from all sources of contaminants
including carbon monoxide, which is found in engine
exhaust, and in any form of combustion. Place the pump
in an area away from vehicle traffic. Do not locate the
pump’s inlet filter near any exhaust system outlet, ventila-
tion flue, or source of fumes or particles of any kind. If the
ambient air pump cannot be placed in an area where
respirableaircanbeguaranteed,useanairinletextension
hose as specified by the pump manufacturer to bring air
from an area where clean respirable air is ensured.
4.2 Air Volume and Pressure
4.2.1 The Apollo 20 LP respirator is designed for use
with ambient pumps, that provides 6 to 15 cfm of Grade D
breathing air at pressures as noted in the table in Section
4.2.2. According to OSHA regulations, the respirator
provides adequate protection at 6 cfm. While 6 cfm is the
minimumrequired airflow, testdata showthatwhen7cfm
or more is used it provides even greater protection for the
user.

9.1.7 Slide one end of the gasket (with lens) onto the
window opening flange, so the holding tab on the opening
is inserted into the gasket retaining slot.
9.1.8 Pushthegasket against theflange,while working
from inside the helmet, push the gasket toward the tab,
until the tab is fully inserted into the retaining slot.
9.1.9 Repeat the process on the opposite side. The
gasket must be pushed beyond the holding tab in order to
insert it into the slot.
9.1.10 Repeat the process on the top and bottom to lock
the gasket in place.
9.1.11 Place perforated cover lenses and one middle
lens in the lens frame per Section 9.2 before closing the
frame.
9.1.12 To maximize the wear life of the inner and middle
lenses, do not remove the last perforated cover lens (See
Section 9.2). The respirator must never be used without
the inner and middle lenses in place.
9.2 Replacing Perforated Cover Lenses, Figure 4
9.2.1 Unlatch and open the lens frame, and remove
remnants of old lenses. If the middle lens is not damaged,
save it for reuse.
9.2.2 Inspect the lens frame gasket and replace if worn
or damaged.
9.2.3 Up to three cover lenses may be installed at one
time. For maximum visibility, install only enough lenses to
last during a work period.
9.2.4 Preparing lenses in the following manner will
permit lenses to be pulled off easily by a user wearing
heavy gloves.
9.2.5 Place the middle lens on a clean flat surface.
Place up to three cover lenses on top of it.
9.2.6 Fold the tab of the bottom lens down as shown in
Figure 4.
9.2.7 Fold the tabs of the second, and top lens up.
9.2.8 Place the stack of prepared lenses into the lens
frame so the folded tab of the top lens sticks through the
front of the lens opening. When placed correctly, the
perforatedlenseswillbeagainsttheframe,andthemiddle
lens will be behind them offering additional support.
9.2.9 Installing the lenses in this manner will prevent
unintentional removal of the last perforated lens and
prolong the life of the middle and inner lenses. It will be
easier to remove the cover lens while wearing heavy
gloves, if the tab is bent outward slightly.
