Hazardous Area Classification Training
Drawing zones that reflect the release sources rather than copying the last drawing
Area classification drawings are frequently inherited, rarely re examined, and often wrong after a plant modification. This course teaches classification from source of release upward, covers both the IEC zone system and the North American division system, and addresses equipment selection and the inspection regime that keeps the protection valid.
This course sits alongside our Hazardous Area Classification consulting work, so what is taught is what we do.
Who should attend
Course content
Every module is taught with worked examples and exercises drawn from real plant, and adapted to your own process where the course runs in house.
Fundamentals
- Flammable limits, flash point, autoignition and how each drives classification
- Gas groups, temperature classes and the properties behind them
- Grade of release from continuous through primary to secondary
Classification method
- Identifying every source of release rather than the obvious ones
- Release rate, ventilation availability and dilution
- Zone 0, 1 and 2 and the equivalent division system
- Zone extent estimation and the point method
- Combustible dust classification and the zone 20, 21 and 22 set
Equipment selection
- Protection concepts including flameproof, increased safety and intrinsic safety
- Marking, certification and understanding what a certificate covers
- Cable entry, glanding and the failures found in practice
Keeping classification valid
- Inspection grades and frequencies
- Management of change when a source of release is added or moved
- Common findings from area classification audits
What you receive
- An area classification worksheet and source of release register
- Worked zone extent calculations
- An equipment selection and inspection checklist
- Assessment result and attendance record
What changes afterwards
- Classification drawings reflect the plant as it now stands
- Equipment installed in classified areas is genuinely suitable for the zone
- Inspection regimes are set to a defensible grade and frequency
- Modifications trigger reclassification instead of quietly invalidating the drawing
Standards and references
We teach Hazardous Area Classification Training against IEC 60079 series, particularly parts 10 1 and 10 2 for classification and the codes listed with it, at the edition current when you run it.
