The following information is provided as general safety guidance for South-Tek Systems nitrogen generators and boosters.
Always follow your facility’s Environmental Health & Safety (EHS) procedures and applicable local regulations.

Overview
High-pressure nitrogen systems can operate at pressures up to 5,000 psi. At these levels, proper safety practices are critical to protect personnel, equipment, and surrounding areas.
This page outlines common safety questions related to operating or maintaining South-Tek Systems nitrogen generators and boosters.
Why are high-pressure safety measures important?
High-pressure nitrogen contains stored energy that can be released suddenly if a fitting, hose, or valve fails.
Even small leaks can pose a hazard. Following the safety measures below helps prevent injury and system damage.
How should the area around the system be controlled?
- Restrict access to authorized and trained personnel only.
- Use temporary barricades or fencing to define a safety perimeter — typically a 10 ft minimum radius.
- Clearly post warning signs such as:
- “High-Pressure Gas System — Authorized Personnel Only”
- “Hearing and Eye Protection Required”
- “Pressurized System — Do Not Enter During Operation”
- Ensure that all piping, fittings, and connections are pressure-rated to at least the Safety Relief Valve (SRV) setting for that specific run.
This ensures the entire system can safely handle full operating and relief pressures, preventing line or component failures.
What personal protective equipment (PPE) is required?
- Eye protection: ANSI-approved safety glasses or face shield
- Hearing protection: Required when the compressor, booster, or venting operations are active
- Hand protection: Cut-resistant or impact-rated gloves when handling fittings or hoses
- Footwear and clothing: Safety shoes and long sleeves are recommended during all maintenance or startup work
Are warning signs required?
Yes. Post durable, easy-to-read signage near system components and entry points, showing:
- System operating pressure (e.g., “5,000 PSI Nitrogen System”)
- PPE requirements
- Emergency shutdown and venting locations
- Authorized personnel notice
Ensure all signage is at eye level and visible from multiple directions.
How can leaks or venting be handled safely?
- Increase system pressure gradually, checking gauges and fittings at each stage.
- Always stand to the side of pressurized components — never in front.
- Use soapy water or approved leak-detection spray; never an open flame.
- During venting or depressurization, ensure everyone is clear of the area and using hearing protection.
- Only trained personnel should perform these steps.
What should be done in an emergency?
If an unsafe condition, leak, or abnormal pressure occurs:
- Immediately shut down both the generator and booster.
- The booster includes a red “Kill Switch” safety button — press this to cut power instantly.
- Close the main nitrogen and air supply valves.
- Evacuate the area if there is any sign of pressure release or component failure.
- Notify your site’s safety officer and South-Tek Technical Support at support@southteksystems.com or via your open service ticket.
- Do not attempt to restart the system until a qualified technician inspects it.
Who can service or adjust the system?
Only qualified technicians or personnel trained by South-Tek Systems should perform any service, adjustment, or startup work.
Unauthorized repairs or pressure adjustments can create unsafe conditions and may void warranty coverage.
Where can I find additional guidance?
Refer to your system manual and the Safety Data Sheet (SDS) for nitrogen gas.
South-Tek can also provide:
- Example barricade and signage templates
- Startup and shutdown checklists
- Onsite safety training recommendations
