Bullard CAB Serie Manual De Usuario

Breathing Air Quality
Respirable, breathable air must be supplied and is the responsibility of the user or employer. Supplied
breathing air must AT MINIMUM meet the requirements for Type 1 gaseous air described in the
ANSI/Compressed Gas Association Commodity Specification G-7.1 for Grade D or higher quality as
specified by Federal regulations 42 CFR, Part 84.141(b) and 29CFR1910.134(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 .............................................................................*
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) or
www.cganet.com for complete details on Commodity Specification G-7.1.
Air Source
Locate the source of supplied air, whether it is a breathing air compressor or an ambient air pump, such as a Bullard Free-Air
far enough from your work site or hazardous exhaust emissions to ensure the air remains contaminant-free.
Always use an inlet filter on your air source. Use suitable after-cooler/dryers with filters, and carbon monoxide monitors and alarms, like the Bullard COM5 OR COM10 CO monitor, 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.
Filtration Efficiency
1st Stage ..................................Particulate/Bulk Liquid Separation .............................................. Auto drain, filter change indicator
2nd Stage .................................Oil Coalescing and Ultra Fine Particulate ................................... Auto drain, filter change indicator
3rd Stage ..................................Activated Charcoal .......................................................................... Manual drain, filter change indicator
These units will not remove Carbon Monoxide (CO), Carbon Dioxide (CO2), Nitrogen, or other toxic gases or fumes. These units will not increase the oxygen content of an air supply
and should not be used when air entering the system is oxygen deficient. Air filtration systems must be operated in the upright position to allow the auto drains to properly seat.
The standard Clean Air Box (CAB) filtration units are not explosion proof and should not be located in an explosive environment.
