OPERATIONS
Limitations of Use
RESPIRATORY
This respirator is NIOSH approved (Continuous-Flow Class) for Type C appli-
cations. It can be worn for general purposes including: spray painting; tank
cleaning; chemical and pesticide handling; and other industrial or agricultural
applications.
This respirator is not approved for use in any atmosphere immediately
dangerous to life or health (IDLH), or from which the wearer cannot escape
without the aid of the respirator. This respirator is not approved for abrasive
blasting.
HEAD
Spectrum respirators DO NOT provide head protection. Wear approved head
protection if head protection is required.
FACE
This respirator’s lens meets ANSI z87.1-1989 faceshield requirements
for impact, penetration and optics. The lens provides LIMITED FACE
PROTECTION. The Spectrum lens is not shatterproof.
EYES
Spectrum respirators provide LIMITED EYE PROTECTION from flying particles
and splash per ANSI z87.1979. Primary eye protection should be worn when
necessary.
Breathing Air Requirements
AIR QUALITY
�
WARNING
THIS RESPIRATOR MUST BE SUPPLIED WITH CLEAN, BREATHABLE AIR,
GRADE D OR BETTER, AT ALL TIMES. THIS RESPIRATOR DOES NOT PURIFY
AIR OR FILTER OUT CONTAMINANTS.
Respirable, breathable air must be supplied to the point-of-attachment of
the approved Bullard air supply hose. The point-of-attachment is the point
at which the air supply hose connects to the air source. A pressure gauge
attached to the air source is used to monitor the pressure of air provided to
the respirator wearer (See Figure 2).
Supplied breathing air must AT A MINIMUM meet the requirements for Type
1 gaseous air described in the Compressed Gas Association Commodity
Specification G-7.1 (Grade D or higher quality), as specified by Federal
Regulations 42 CFR, Part 84.141 (b) and 29 CFR 1910.134 (i).
The requirements for Grade D breathable air include:
-Oxygen ................................................ 19.5-23.5%
-Hydrocarbons (condensed)
in mg/m3 of gas ......................5 mg/m3 max.
-Carbon monoxide ..............................10 ppm max.
-Carbon dioxide .............................1,000 ppm max.
-Odor ...............................lack of noticeable odor*
-No toxic contaminants at levels that make air unsafe to breathe.
*Specific measurement of odor in gaseous air is impractical. Air may
normally have a slight odor. The presence of a pronounced odor should
render the air unsatisfactory.
Contact the Compressed Gas Association (1725 Jefferson Davis Highway,
Arlington, VA 22202) for complete details on commodity Specifications G-7.1
AIR SOURCE
Locate the source of supplied air, whether it is an air compressor or an
ambient air pump, such as a Bullard Free-Air
®
pump, in a clean air envi-
ronment. Locate the air source far enough from your work site to ensure
the air remains contaminant-free. Always use an inlet filter on the air
source. Use suitable filters and carbon monoxide monitors and alarms,
like Bullard’s CAB Series of CO monitors, as necessary to assure clean,
breathable air at all times. The air should be regularly sampled to be
sure that it meets Grade D requirements.
Breathing Air Pressure
Air pressure must be continually monitored at the point-of-attachment while
operating this respirator. A reliable air pressure gauge must be present to permit
you to continually monitor pressure during actual respirator operation.

WARNING
FAILURE TO SUPPLY THE MINIMUM REQUIRED PRESSURE AT THE POINT-
OF-ATTACHMENT FOR YOUR HOSE LENGTH AND TYPE WILL REDUCE AIR-
FLOW AND MAY CAUSE INJURY, DISEASE OR DEATH.
The Breathing Air Pressure Tables (See pages 13-19) define the air pres-
sure ranges necessary to provide Spectrum-CF respirators with a volume
of air that falls within the required range of 4-15 cfm (Ref. 42 CFR, Part 84,
Subpart J.84.150) when operated in continuous-flow mode. Make sure you
understand the information in the Breathing Air Pressure Table (see page 10)
before using this respirator.
1. Be sure your Bullard air supply hose(s) (column 1) is approved for use
with your breathing tube assembly.
2. Determine that your Bullard air supply hose is within the approved length
(column 2).
3. Locate your flow control device (column 3).
4. Make sure you have not exceeded the maximum number of hose sections
(column 4).
5. Set the air pressure at the point-of-attachment within the required
pressure range (column 5) for your breathing tube assembly and air
supply hose type and length. Accurate pressure readings can only be
attained when air is flowing into the respirator.
