Dedika is a platform for learning by doing: whether it's creating a business proposal, becoming a manicurist, or using a new tool, for example. Whatever your goal, the best content on the subject already exists. But it's often in another language, expensive, scattered around, lacking practical activities, or part of a course that's too long for a busy routine. That's why Dedika has its own method: we find this material wherever it is, organise what makes sense for your goal, review it with the help of experts who are available to answer questions, and create practical exercises so you can learn by doing. You are the most important part of your journey and no one knows it better than you: choose the content and course length, decide whether to learn online or offline, and pick your preferred format. It could be video, text, audio, or a summary. Your way, only with what makes sense for you. Here, every moment of dedication counts for more and you reach what matters faster.

Our courses include a summary at the end of each chapter, from which you can download a PDF and print it.

Chapter 3See details

Hazardous Area Classification in Practice

Lesson 1 • Classification Review and Validation
Establishes criteria for peer review, management of change, and periodic revalidation. Ensures classification remains accurate as processes and facilities evolve.
Lesson 2 • Source of Release Analysis
Teaches identification and grading of continuous, primary, and secondary release sources. Directly determines zone type and spatial extent on site drawings.
Lesson 3 • Classification Methodology and Process
Outlines the step-by-step process for conducting hazardous area classification studies. Establishes a repeatable workflow applicable to any industrial site.
Lesson 4 • Producing Classification Drawings
Guides creation of scaled zone drawings with correct notation and legend standards. Drawings form the core deliverable of the classification study.
Lesson 5 • Ventilation Assessment Techniques
Covers natural and forced ventilation evaluation and its effect on zone extent. Ventilation grade directly modifies zone boundaries in classification outputs.

Chapter 4See details

Explosion-Proof Equipment Selection

Lesson 1 • Temperature Class and Gas Group Matching
Explains how to match equipment temperature class and gas group to site hazards. Prevents ignition by ensuring equipment surface temperatures remain safe.
Lesson 2 • Protection Concepts for Electrical Equipment
Surveys flameproof, intrinsic safety, increased safety, and other protection types. Enables informed selection based on equipment function and zone location.
Lesson 3 • Equipment Procurement and Verification
Covers specification writing, supplier qualification, and certificate verification processes. Ensures only compliant equipment enters the classified area.
Lesson 4 • Equipment Protection Levels and Categories
Defines equipment protection levels and their correspondence to zone requirements. Provides the decision matrix for equipment selection in any classified area.
Lesson 5 • Non-Electrical Equipment Protection
Addresses protection concepts for mechanical, pneumatic, and hydraulic equipment. Extends selection competency beyond electrical systems to all equipment types.

Chapter 5See details

Explosion Risk Assessment Methods

Lesson 1 • Risk Assessment Documentation and Review
Establishes standards for recording, communicating, and updating explosion risk assessments. Ensures assessments remain valid and actionable throughout the facility lifecycle.
