Minimum Standards

Today's message comes from the President of CIC:

No one would proclaim someone a good person simply because they haven’t been thrown in jail yet. Obeying the law is a minimum. It is not an ideal. It is not even an achievement. Likewise, the industry standards such as CENELEC or ATEX or NFPA norms are minimums. It is what is necessary and probably sufficient to prevent fires and explosions. We say “probably” sufficient because even installations that seem to meet all the code requirements still experience fires and explosions, just at a much lower rate than others. 

Flammability Analyzers for Process Applications

Industry standards have been established which set minimum levels of performance for flammable gas detectors. Sensors which are successfully tested and approved to these minimum standards can be listed and labeled. There are however, special requirements for solvent vapor moitoring. 

Our article in FS-World Magazine describes the considerations required when selecting a flammability analyzer for process applications.

Manufacturing Day 2015

Happy MFG DAY 2015!!

Manufacturing Day is a celebration of modern manufacturing meant to inspire the next generation of manufacturers. It's a celebration of what 12 million people around the United States, inlcuding employees of this company, experience every day - pride at working in manufacturing. Although Manufacturing Day officially occurs on the first Friday in October, any day can be a Manufacturing Day.

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:

Meeting NFPA 86: Reading Error

An interesting conversation arose after last week's discussion on calibration accuracy. What happens when a variety of solvents are used in a process? 

A note in NFPA 86 section 11.6.10.6 states “Where a variety of solvents are used, the solvent to which the controller is least sensitive shall be the primary calibration reference.”

Meeting NFPA 86: Calibration Accuracy

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

Meeting NFPA 86: Speed of Response

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