Meeting NFPA 86:Summary

For the past several weeks we've been discussing how to select a continous solvent vapor analyzer to meet NFPA 86 requirements, specifically focusing on the 6 essentials necessary to do so:

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:

Meeting NFPA 86: Failsafe Malfunction Logic

We've discussed the 6 essentials of meeting NFPA 86, this week let's take a closer look at the fifth monitoring requirement: failsafe malfunction logic.

According to section 11.6.10.8 of NFPA 86, "alarms shall be provided to indicate any sample, flow, circuit or controller power failures."

Meeting NFPA 86: Avoiding Condensation

We've discussed the 6 essentials of meeting NFPA 86, this week let's take a closer look at the fourth monitoring requirement: avoiding condensation.

NFPA 86 Section 11.6.10.11 requires that “the sensor and sample system shall be maintained at a temperature that prevents condensation.”

Condensation of any part of the vaporized sample will create two types of problems:
