WARNING
8. Be certain your employer has determined that the breathing air source provides at least Grade
D breathable air. This respirator must be supplied with clean breathable air at all times.
9. Do not connect the respirator’s air supply hose to nitrogen, oxygen, toxic gases, inert gases or
other unbreathable, non-Grade D air sources. Check the air source before using the respirator.
Failure to connect to the proper air source may result in serious injury or your death.
10. Do not use this respirator in poorly ventilated areas, areas where oxygen content is less than
19.5%, or confined spaces such as tanks, small rooms, tunnels or vessels.10. Do not use this
respirator in poorly ventilated areas, areas where oxygen content is less than 19.5%, or confined
spaces such as tanks, small rooms, tunnels or vessels unless the confined space is well-ventilated
and contaminant concentrations are below the upper limit recommended for this respirator.
In addition, follow all procedures for confined space entry, operation and exit as defined in
applicable regulations and standards, including 29 CFR 1910.146.
11. If you have any questions concerning the use of this respirator, or
if you are not sure whether the atmosphere you are working in is immediately dangerous to your
life or health (IDLH), ask your employer. All instructions for the use and care of this product must
be supplied to you by your employer as recommended by the manufacturer and as required by
Federal Law (29 CFR 1910.134).

WARNING
1. This respirator, when properly fitted and used, significantly reduces, but does not completely
eliminate, the breathing of contaminants by the respirator wearer. You may obtain better
respiratory protection from other types of respiratory protection equipment such as a valve-
operated pressure-demand airline respirator or a pressure-demand self-contained breathing
apparatus respirator.
2. Before using this respirator, be sure your employer has determined that airborne contaminant
concentrations do not exceed those allowed by applicable OSHA, MSHA, EPA, NIOSH or ACGIH
regulations and recommendations, or any other applicable regulations for continuous-flow airline
respirators. Federal law requires that your employer measure and monitor airborne contaminant
levels in the work area.
3. Improper respirator use may damage your health and/or cause your death. Improper use may
also cause certain life-threatening delayed lung diseases such as silicosis, pneumoconiosis or
asbestosis.
4. DO NOT wear this respirator if any of the following conditions exist:
- Atmosphere is immediately dangerous to your life or health (IDLH).
- You CANNOT escape without the aid of the respirator.
- Atmosphere contains less than 19.5% oxygen.
- Work area is poorly ventilated.
- Unknown contaminants are present.
- Contaminants are in excess of regulations or recommendations (as described in item
2 above).
5. Bullard recommends that you not wear this respirator until you have passed a complete
physical exam (perhaps including a lung x-ray) conducted by qualified medical personnel and
have been trained in the respirator’s use, maintenance and limitations by a qualified individual
(appointed by your employer) who has extensive knowledge of the Bullard GR50 respirator.
6. DO NOT modify or alter this respirator in any manner. Use only NIOSH- approved Bullard GR50
components and replacement parts manufactured by Bullard for use with this respirator.
Failure to use NIOSH-approved Bullard components and replacement parts such as lenses, hoses,
flow control devices and climate control devices, voids NIOSH approval of the entire respirator,
invalidates all Bullard warranties and may cause death, lung disease or exposure to other
hazardous or life-threatening conditions.
7. Inspect all components of this respirator system daily for signs of wear, tear or damage that
might reduce the degree of protection originally provided.
Immediately replace worn or damaged components with NIOSH- approved Bullard GR50
components or remove respirator from service. (See INSPECTION, CLEANING AND STORAGE
section on pages 16 and 17 for proper maintenance of the GR50 Series respirator.)
