•What is Intrinsically Safe?•Why is it important?•Where is it used, for what applications?•What does a solution look like?
What is Intrinsically Safe?
A design technique to limit energy (electrical and/or thermal) below a level required to ignite a specific hazardous atmospheric mixture.
Why is it important?•Minimize loss of life and injuries•Minimize property damage

APPLICATIONS forNEW ATEX SYSTEM – HygroFlex5-EX
What does this all mean?Let’s break it down,
first by Class
• Class 1- flammable gases or vapors
• Class 2- combustible dust present
• Class 3- ignitable fibers present
What does this all mean?Let’s break it down,
Next by division / quantifying
• Division 1- the hazardous material present has a high probability of producing an explosion
• Division 2- the hazardous material present has a low probability of producing an explosion
• Divisions in the EU are defines as Zones.
What does this all mean?Let’s break it down,
Next by group
• What materials are present to cause explosion.
