Gas Detection & Toxic Exposure Limits
Industrial gas detection systems are designed based on exposure limits defined by OSHA, NIOSH, and ACGIH. Typical thresholds include CO (35 ppm REL), H2S (100 ppm IDLH), and oxygen deficiency below 19.5%.
These parameters directly influence detector selection, alarm setpoints, and ventilation system integration in enclosed areas such as basements, DG rooms, and tunnels.
View Questions →HVAC & Ventilation (Air Changes Per Hour, Smoke Control)
Ventilation systems are engineered based on air changes per hour (ACH), pressure differentials, and smoke control requirements as per ASHRAE and NFPA standards.
Typical applications include basement ventilation (6 ACH), stairwell pressurization, and smoke extraction systems in commercial buildings.
View Questions →Fire & Life Safety
Fire and smoke control systems must comply with UL555 and UL555S standards for damper leakage and operational integrity under elevated temperatures.
System design includes fire dampers, smoke dampers, and integrated detection systems aligned with NFPA codes.
View Questions →Electrical Systems (Cable Sizing, Ampacity, Grounding)
Electrical system design involves cable sizing, ampacity calculations, grounding systems, and load analysis based on IEC, NEC, and IEEE standards.
Critical considerations include temperature derating, installation conditions, and fault protection mechanisms.

Common Toxic Gas Exposure Limits (CO, H2S, Oxygen) – OSHA / NIOSH Reference Table
The following table summarizes commonly referenced toxic gas exposure limits used in industrial safety and gas detection system design:
| Gas | Limit Type | Value |
|---|---|---|
| Carbon Monoxide (CO) | NIOSH REL | 35 ppm |
| Hydrogen Sulfide (H2S) | IDLH | 100 ppm |
| Oxygen (O₂) | Deficiency Level | < 19.5% |
