BREATHING AIR QUALITY TESTING

Compressed breathing air quality testing is essential to ensuring the safety of individuals relying on such air for breathing.  Especially in environments like scuba diving, firefighting, and industrial settings, where breathing air quality standards need to be ensured.

The breathing air quality analyzers from SUTO iTEC are engineered to provide outstanding precision and dependability when assessing the compressed breathing air quality. By using cutting-edge sensor technology, these devices can identify and measure contaminants in the breathing air. Thanks to this precise measurement, the breathing air analyzers make sure that the breathing air either exceeds or meets the strict requirements established by industry guidelines and regulatory organizations.

The following are some important questions and answers about checking compressed breathing air quality:

Breathing Air Quality Testing: Frequently Asked Questions

Why is Compressed Breathing Air Quality Testing Important?

  • Ensuring safety: Immediately identify and address air quality issues to ensure occupant safety.
  • Compliance confidence: Meet and exceed regulatory requirements with real-time monitoring data.
  • Preventive Action: Promptly address potential hazards and prevent health risks before they escalate.

What Contaminants Are Typically Tested in Compressed Breathing Air?

In response, typical contaminants include particulate parts, water vapor, oil, carbon monoxide (CO), and carbon dioxide (CO2). The health risks associated with each contaminant are unique, and their concentrations need to stay below reasonable bounds.

Which Standards Apply to the Quality of Compressed Breathing Air?

Depending on the use, different international norms and laws are applicable. OSHA requirements for industrial breathing air, NFPA 1989 for firefighter breathing air, and CGA Grade E for compressed breathing air used in scuba diving are examples of common regulations.

What Steps Should Be Taken if Contaminants Exceed Acceptable Levels?

When the breathing air quality testing indicates that the levels of contaminants are higher than acceptable, corrective actions are required. This could entail changing filters, performing routine maintenance on the compressor system, and retesting the air until it satisfies the requirements. Affected people should also get medical help if they have come into contact with contaminated air.

Are There Portable Tools for Compressed Breathing Air Testing on-Site?

In order to test compressed breathing air quality in real time on-site, portable breathing air analyzers are available. With their ability to provide quick feedback on air quality, these devices are especially helpful in field applications.

Thomas Fischer

Operators of breathing air systems are required to fill respiratory air in line with international standards such as EN 12021 or CFSR 1910.134(d). Potential hazards due to impurities in the breathing air can have consequences which endanger health or which are even life-threatening.

Regular checks with the Breathing Air Analyzer S605 is an indispensable part for a safe operation.

State-of-the-art Measurement Technology

With the powerful combination of several sensor technologies, SUTO iTEC’s Breathing Air Quality Analyzers and testing equipment are capable of monitoring all relevant breathing air quality contaminants.

Thomas Fischer

1. Oxygen Measurement (O2)

For safety reasons, it is recommended to measure the oxygen level in the breathing air. The optical oxygen sensor monitors the Ocontent and indicates deviations from the standard concentration.

Thomas Fischer

2. Carbon Dioxide Measurement (CO2)

The intake air may also be exposed to an increased concentration of carbon dioxide. Filter material used in compressed air can adsorb, but also release CO2. The gas is measured by the NDIR sensor to avoid extreme concentrations above 1000 ppm.

Thomas Fischer

3. Carbon Monoxide Measurement (CO)

The compressor intake air may be contaminated with CO due to nearby combustion engines or heating systems. Carbon monoxide is a toxic and life-threatening gas that will be monitored accurately by an electrochemical sensor.

Thomas Fischer

4. Humidity Measurement (H2O)

High humidity can cause corrosion and, in severe cases, lead to bursting air containers. In a cold environment, it can freeze and block the air supply. The integrated dew point sensor is crucial to checking the proper water removal of the dryers and filters.

Thomas Fischer

5. Oil Vapor Measurement

Atmospheric oil vapor contained in industrial air environments can get into the system through the compressor or intake. Compressed into the breathing air, the oil contaminants can cause health issues. The state-of-the-art sensor technology detects the oil contaminants immediately.

6. Pressure Measurement

The pressure sensor provides additional pressure data about the compressed air system using state of the art sensor technology.
