20LF Series Respirator Facepiece
User Manual for use with Supplied-Air Respirators
Inspection, Cleaning, and Storage
Bullard 20LF Series respirators have a limited service life. Therefore, a
regular inspection and replacement program must be conducted. Bullard
20LF Series respirators and all component parts and assemblies should be
inspected for damage or excessive wear before and after each use to ensure
proper function. Immediately remove the respirator from service and replace
parts or assemblies that show any sign of failure or excessive wear that
might reduce the degree of protection originally provided.
Use only Bullard 20LF Series respirator components and replacement
parts manufactured by Bullard and approved for use by NIOSH with these
respirators. Since respirator use and wear varies with each job site, it is
impossible to provide a specific time frame for respirator replacement.
Respirators used by more than one person must be cleaned, inspected, and
sanitized after each use.
WARNING
The air you breathe will not be clean unless the respirator you wear is
clean. Failure to heed this warning could result in death or serious injury.
WARNING
Do not use volatile solvents for cleaning this respirator or any parts and
assemblies. Strong cleaning and disinfecting agents, and many solvents,
can damage the plastic parts and reduce the protective properties of
the respirator. Failure to heed these instructions may result in minor or
moderate injury and/or equipment damage.
WARNING
Do not store the respirator in your work area or leave it unattended
in a contaminated environment. Respirable contaminants can remain
suspended in the air for several hours after work activity ceases, even
though you may not see them. Proper work practice requires you to wear
the respirator until you are outside the contaminated area. If you place
or store the respirator in a contaminated environment, contaminants,
dirt, and dust could get into the respirator. When you put the respirator
back on, you could breathe in contaminants upon reuse. Failure to heed
these instructions could result in death or serious injury.
Facepiece
Inspection
Before and after every use, inspect the facepiece material for rips, tears,
or damage from excessive wear that might reduce the degree of protection
originally provided. The respirator’s plastic lens should be inspected for
cracks, scratches or any other signs of damage.
If damage is detected, remove the facepiece from service and discard
immediately.
Cleaning
Bullard does not recommend laundering the facepiece. The facepiece should
be hand-sponged with warm water and mild detergent, rinsed, and air-dried.
Abrasive cleaning or solvents may damage the lens or leave harmful residue
in the facepiece if improperly rinsed or aired out.
Breathing Tube
Inspection
Inspect the breathing tube for tears, cracks, holes, or excessive wear that
might reduce the degree of protection originally provided. If any signs of
excessive wear are present, remove the breathing tube from service and
discard immediately.
Inspect the gasket seal on the flow control end, if missing or worn, remove
the respirator from service until replaced – there is no gasket seal on the
facepiece-end of threaded connections.
Cleaning
To clean the breathing tube, hand-sponge with warm water and mild
detergent, being careful not to get water inside. Rinse and air-dry. Avoid
solvents and harsh cleansers.
WARNING
Do not cut or remove the foam that is inside the 20LF Series Airline
Respirator breathing tube. The foam helps reduce the noise level of the
incoming air supply. It does not filter or purify your breathing air. NIOSH
has approved this respirator with the foam in place. Failure to follow
these instructions may result in minor or moderate injury and/or equip-
ment damage.
Flow Control Device
Inspection
Inspect the flow control device including adjustable knobs and tubes for
cracks, holes, or excessive wear that might reduce the degree of protection
originally provided. If any signs of excessive wear are present, remove the
flow control device from service. Replacement belts are available for all flow
controls.
Cleaning
To clean, hand-sponge with warm water and mild detergent, being careful not
to get water inside. Avoid solvents and harsh cleansers.
Air Supply Hoses
Inspection
Air supply hose(s) should be inspected closely for abrasions, corrosion, cuts,
cracks, and blistering. Be sure the hose fittings are crimped tightly to the
hose so that no air can escape. Make sure the hose has not been kinked or
crushed by any equipment that may have rolled over it.
If any of the above signs are present or any other signs of excessive wear are
detected, replace the hose(s) immediately and remove from service.
Cleaning
The air supply hose(s) should be hand-sponged with warm water and mild
detergent, rinsed and air dried. Do not get water inside the air supply hose.
Avoid solvents and harsh cleansers.
WARNING
Only use air supply hoses that are NIOSH approved for use with the 20LF
Series respirator. Other hoses could reduce airflow and protection, and
expose the wearer to life-threatening conditions. Failure to follow these
instructions could result in death or serious injury.
Storage
After reusable respirator components have been cleaned and inspected, place
them in a plastic bag or an airtight container. Store the respirator and parts
where they will be protected from contamination, distortion and damage from
elements such as dust, direct sunlight, heat, extreme cold, excessive moisture
and harmful chemicals. Five-year maximum shelf life.
