Understanding the Role and Importance of Pressure Relief Valves (100 PSI) in Lab Safety

by

Why 100 PSI Matters

In microbiology autoclaves and fermenters, overpressure incidents above 100 PSI account for 14 % of lab safety alerts (OSHA, 2024). A properly rated pressure relief valve (PRV) prevents catastrophic vessel failure.

Key Functions

  • Overpressure Protection: Opens within ±5 PSI of set point.
  • Automatic Reseal: Closes once pressure drops 10 % below set value.
  • Corrosion Resistance: 316L stainless extends service life to 5 years in humid environments.

Inspection Checklist

  1. Verify set point annually with a calibrated gauge.
  2. Check for seat deposits; debris can raise opening pressure by 20 %.
  3. Document serial numbers for ISO 9001 traceability.

Conclusion

A 100 PSI PRV is a small investment that averts costly equipment damage and safeguards lab personnel.
