Back to the Basics: Safe reduction of ventilation

Last week we discussed the 2 cases at which the authorities have determined that certain industrial processes can proceed at solvent vapor concentrations up to, but not exceeding, some percentage of the Lower Flammable Limit.

Let’s focus on case #2: What happens when an analyzer and control system are used? 

Back to the Basics: Limits to solvent vapor concentration

The authorities have determined that certain industrial processes can proceed at solvent vapor concentrations up to, but not exceeding, some percentage of the Lower Flammable Limit. 

In general, there are two cases:

  1. The fundamental safety limit
  2. The limit when an analyzer and control system are used

This week let's take a look & expand upon Case #1: Fundamental ventilation requirements.

Back to the Basics: Temperature Effects on LFL

So we know what the LFL is and how it's determined, but what about the factors that can effect these values?

Back to the Basics: Variation in Published LFL Values

Now that we understand what the Lower Flammable Limit is, let's look at how these values are determined and what that means for your application. 

LFL is determined empirically. This means that there are variations in the values published by different authorities at different times. 

It is likely that the following test conditions account for the deviations in these published values:

Back to the Basics: LFL

For each flammable substance there is a level of concentration in air, usually expressed as a percent by volume, that is known as its Lower Flammable Limit, LFL, or Lower Explosive Limit, LEL. Below the LFL, the mixture of fuel and air is too lean to support combustion.

There are 3 important factors to consider when measuring flammability: 

Back to the Basics: The Role Of The Analyzer

Hello 2016.

The clean slate of the new year makes it the ideal time to make a firm decision to facilitate improvement in some area of your life or business.

Many businesses make resolutions, but when they don’t work, it’s often because the goals are impossible to achieve, the fixes that are needed can’t happen in a short time, or there are simply too many. Because the success rate for resolutions is so low, it would be wise to continually review your goals, examine what has brought success, and go back to the basics.

Plan for Resolution Success

Christmas is almost here. Your shopping is nearly complete. Friends and relatives are making plans to celebrate together. After all the season's greetings have come to an end, it will be time to ring in a new year.
