Doffing the GR50
Inspection, Cleaning and
Storage
Bullard GR50 Series respirators have a limited
service life. Therefore, a regular inspection and
replacement program must be conducted.
The Bullard GR50 Series respirator and all
component parts and assemblies should be
inspected for damage or excessive wear before
and after each use to ensure proper functioning.
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 complete NIOSH-approved Bullard
GR50 Series components and replacement parts
on this respirator. Refer to parts list for correct
part numbers.
Since respirator use and the quality of
maintenance performed vary with each job site,
it is impossible to provide a specific time frame
for respirator replacement.
This respirator should be cleaned and sanitized
at least weekly, or more often if subjected to
heavy use. Respirators used by more than one
person must be cleaned, inspected and sanitized
after each use. If not cleaned, contamination
may cause illness or disease.
REMEMBER, THE AIR YOU BREATHE
WILL NOT BE CLEAN UNLESS THE
RESPIRATOR YOU WEAR IS CLEAN.
Hood and Headband
INSPECTION: Inspect the hood 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.
Disassemble the breathing tube from the hood
by removing the nylon hose clamp. To remove
the hose clamp, slide the locks sideways in
opposite directions.
Remove the headband suspension and optional
chin strap from the hood. Inspect headband
for cracks, frayed or cut crown straps, torn
headband or size adjustment slots, loss of
pliability or other signs of excessive wear. Check
the chin strap for loss of elasticity, cuts and
cracked hanger clips.
If damage is detected, replace immediately
with Bullard replacement part(s) or remove the
respirator from service.
CLEANING: To clean the GR50 respirator hood,
remove suspension and optional chin strap.
With MB1 or GRHOL1 lens attached, hand-
wash the GR50 hood in warm water using a
mild liquid detergent. Rinse hood with cold
water and allow to air-dry. After cleaning and
before reassembling, inspect the hood for signs
of excessive wear, following the inspection
instructions on this page. If damage is detected,
remove the respirator from service.
The inner lens, headband suspension and
optional chin strap should be hand-sponged with
warm water and mild detergent, then rinsed and
air-dried. Before reassembling, carefully inspect
parts for signs of damage.
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.

Doffing
When finished working, leave work area wearing
respirator and with air still flowing. Once outside
contaminated area, remove respirator and then
disconnect the air supply hose using the quick-
disconnect fittings.
NOTE
If using V20 Series (1/2”
I.D.) air supply hose, the hose
quick-disconnect coupler does
not have a shut-off valve.
Therefore, air will continue
to flow freely after hose is
disconnected from respirator.

WARNING
Leave work area immediately if:
- Any respirator component becomes damaged.
- Airflow into respirator hood stops or slows down.
- Air pressure gauge drops below the minimum specified in Breathing Air Pressure Table (page 9).
- Breathing becomes difficult.
- You become dizzy, nauseous, too hot, too cold or ill.
- You taste, smell or see contaminants inside respirator hood.
- Your vision becomes impaired.
�
WARNING
DO NOT LEAVE RESPIRATOR IN WORK AREA OR LEAVE IT UNATTENDED IN A CONTAMINATED
ENVIRONMENT. RESPIRABLE CONTAMINANTS CAN REMAIN SUSPENDED IN AIR FOR MORE
THAN ONE HOUR 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 SET THE RESPIRATOR DOWN 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.
