Meeting NFPA 86: Maintenance

We've discussed the 6 essentials of meeting NFPA 86, this week let's take a closer look at the sixth monitoring requirment: maintenance.

The system should be designed to provide the least amount of downtime, including routine calibration and maintenance of the sampling system and sensor.

Calibration frequency depends on sensor type:

1. catalytic sensors require the most frequent calibration checks.
2. Flame temperature sensors require the least frequent calibration check schedule.

Maintenance time also depends on sensor type and sampling system. Insufficiently heated sampling systems will result in condensation, clogging and excessive maintenance:

• Flame Ionization (FID) sensors typically require the greatest amount of maintenance
• Infrared, catalytic and flame temperature have lower maintenance requirements
