Safety Guidelines

General Safety Measures

Authorized Access Only:

Only trained and authorized personnel may operate, service, or maintain the PSA nitrogen generator.
Unauthorized access to the equipment is prohibited.

Personal Protective Equipment (PPE):

Always wear appropriate PPE, including safety glasses, gloves, and steel-toe boots.
Use hearing protection in high-noise environments

Site and Environment:

Ensure the generator area is well-ventilated to prevent oxygen displacement.
Maintain a clean, debris-free workspace to avoid tripping hazards and ensure proper airﬂow.
Check that all warning labels and safety instructions are clearly visible and legible.

Emergency Preparedness:

Know the location of ﬁre extinguishers, eyewash stations, and emergency stop buttons.
Familiarize yourself with site-speciﬁc emergency evacuation plans and shutdown procedures.

Daily Safety Checks

Inspect for Leaks: Perform a visual inspection to check for gas leaks, wear, or damage to piping, hoses, or ﬁttings.
Check Pressure and Purity: Verify system pressure, nitrogen purity, and ﬂow rate against expected values.
Monitor Ambient Conditions: Ensure the area is within the temperature and humidity range speciﬁed by the manufacturer.
Power Supply: Inspect cables and electrical connections for damage or loose ﬁttings.

Day-to-Day Operational Guidelines Daily Startup Procedure

Pre-Startup Inspection:

Check that all valves are in their proper positions.
Ensure ﬁlters are clean and installed correctly.
Conﬁrm that the air compressor supplying the generator is operational and within its speciﬁed parameters.

System Initialization:

Follow the manufacturer's startup procedure step by step.
Gradually open isolation valves to prevent pressure surges.
Monitor the initial startup for any unusual sounds, vibrations, or pressure irregularities.

System Monitoring:

Continuously monitor the system dashboard or indicators for key metrics:
- Nitrogen purity (%).
- Pressure levels (PSI/bar).
- Flow rate (SCFM or other unit).
Log these parameters for tracking and troubleshooting.

Daily Operational Best Practices

Performance Monitoring:

Check nitrogen purity levels at regular intervals to ensure consistent output quality.
Verify that system pressure remains within safe operating limits.
Observe ﬂow rates to match the demand requirements of your process.

System Cooling and Ventilation:

Ensure that the generator's cooling system (if applicable) is functioning correctly.
Verify that the ventilation system is unobstructed and eﬀectively dissipates heat.

Preventative Measures:

Do not exceed the generator's rated capacity for prolonged periods.
Avoid unauthorized adjustments to system controls or settings.

Environmental Monitoring:

Use oxygen detectors in enclosed areas to ensure safe breathing conditions.
Avoid using the generator near ﬂammable or corrosive substances.

Daily Shutdown Procedure

System Shutdown:

Follow the manufacturer’s recommended shutdown procedure.
Depressurize the system by slowly closing the isolation valves.
Turn oﬀ the power supply to the generator.

Post-Shutdown Inspection:

Inspect for leaks or abnormalities that may have occurred during operation.
Check oil levels and coolant levels (if applicable) in associated compressors.

Documentation:

Record system performance metrics and note any irregularities in a maintenance log.
Report unusual issues to the site supervisor immediately.

Maintenance and Servicing

Routine Maintenance (Daily/Weekly):

Filter Inspection: Check and replace air intake and coalescing ﬁlters if they show signs of clogging or wear.
Visual Inspection: Inspect all connections, hoses, and valves for signs of wear, corrosion, or damage.
Drain Maintenance: If applicable, ensure condensate drains are functioning correctly and are not clogged.

Periodic Maintenance (Monthly/Quarterly):

System Calibration: Test purity analyzers and recalibrate if necessary to ensure accuracy.
Adsorbent Maintenance: Replace the molecular sieve or adsorbent material as speciﬁed in the maintenance schedule.
Pressure Relief Devices: Test and verify the functionality of pressure relief valves to ensure safety.

Incident Response

Gas Leaks:

Evacuate the area immediately if a leak is suspected.
Use gas detectors to conﬁrm the presence of nitrogen or air leaks.
Notify site safety personnel and follow emergency response procedures.

System Failures:

Shut down the system if alarms indicate critical issues.
Do not attempt repairs without proper authorization and training.

Emergency Shutdown:

Activate the emergency stop button if required to protect personnel or equipment.

Documentation and Reporting

Daily Logs:

Maintain a log of daily performance metrics, including purity, pressure, and ﬂow rates.
Record any maintenance performed or irregularities observed.

Incident Reports:

Document all incidents, including gas leaks, system alarms, or operator errors.
Submit reports to supervisors for review and corrective action.

Important: Always refer to the manufacturer's manual for speciﬁc instructions and site-speciﬁc safety protocols. Consistent adherence to these safety and operational guidelines will ensure optimal performance and the safety of personnel.
