• Acquire knowledge on the monitoring and protection of chemicals and the environment including the legislative control governing these chemicals, proper waste management and environmental impact assessment
• The documentation of the hazardous area

This programme is intended to give:

• An in depth understanding of hazardous areas from the initial nature of the problem
• Some case studies of industrial accidents, through the identification and classification of the hazard, selection and use of protected equipment
• The administration of hazardous areas in terms of record keeping and certificates

Training Methodology

This is an interactive course. There will be open question and answer sessions, regular group exercises and activities, videos, case studies, and presentations on best practice. Participants will have the opportunity to share with the facilitator and other participants on what works well and not so well for them, as well as work on issues from their own organizations. The online course is conducted online using MS-Teams/ClickMeeting.

Who Should Attend?

This five-day program is a single and comprehensive training package that involves a combination of formal lectures, practical exercises, demonstrations, and written exercises.

It is primarily aimed at:

• Safety  engineers or supervisors
• Electrical, instrumentation engineers or technicians

It is assumed that most attendees will be familiar with industrial electrical practice although specific prior knowledge of hazardous areas is not a prerequisite

Course Outline

Day 1:

• Introduction and History 
• A brief history of Industrial fires and explosions
• Materials 
• Understanding the important characteristics of hazardous materials and how they behave when they are ignited. Looking at the data tables and seeing how, Flashpoint, boiling point, L.E.L., etc. influence our approach to the materials
• Area Classification
• A look at the techniques and the procedures that result in the formal allocations of zones zero, one, and two
• Sources of Hazard, duration of release, the extent of zones, calculations, nature of the hazard, and release characteristics

Day 2:

• Area Classification Exercise
• An exercise carried out in syndicate groups where a small plant is classified against the IP code of practice. This will give attendees a much clearer idea of what zone 0, zone1, and zone2 really mean at their own place of work
• Apparatus Groups and Temperature Classes
• How apparatus and hazard materials are matched together in terms of ignition energies, flame transmission characteristics, and ignition temperatures. How groups and T Classes have changed over the years and from country to country and where to find the information to make comparisons
• Source of Ignition 
• A look at some of the possible sources of ignition, e.g. static electricity, light metal termite reactions, friction, etc., which can occur in hazardous areas. Also, consider some of the steps which can be taken to eliminate them
• Methods of Protection
• Considering the recognized methods of protection. The fundamental concept in each case and the zones in which they may be employed
• Ex d Flameproof
• Ex i Intrinsic Safety
• Ex e Increased Safety
• Ex p Pressurised
• Ex N Type N 
• Ex m, Ex o, Ex q, Ex s
• Exercise
• A written exercise in which the relationship between zones, Apparatus groups, temperature classes and certifies electrical equipment is examined
• Ex d Flameproof
• Considering in depth the concept of Flameproof protection, how it works, how is must be installed, how it must be inspected & maintained. Looking at weatherproofing, corrosion, gaps, fasteners, etc

Day 3:

• Equipment Inspection Exercise Session 1
• Examining samples and answering questions about them
• Intrinsic Safety
• As for flameproof, an in-depth look at the subject considering minimum ignition energies, associated apparatus and systems, simple apparatus, IS clean earth, floating systems, system matching, etc
• Intrinsic Safety Installation
• Segregation of cables, screens and armor, earthing and bonding, induction and invasion, creepage and clearance etc 
• Increased Safety
• An in-depth look at this concept of protection making comparisons with flameproof, and stressing the vital importance of correct installation. Also looking at weatherproofing IP rating, CTI, stoppers and bolts, derating etc.
