You'll cover atmospheric monitoring, ventilation, PPE selection, and emergency response from the ground up. Every regulation, every role, and every risk is addressed so your team goes in prepared and comes out safe.

Dedika for businesses

What you will learn:

You will learn how to classify confined spaces, recognize atmospheric and physical hazards, and apply the correct controls before anyone steps inside. The course covers gas detection instrument operation, ventilation planning, and permit writing from start to finish. You will understand the duties of every team member — entrant, attendant, and entry supervisor — and know exactly when to evacuate. Rescue planning, PPE selection, and emergency response procedures are all included. By the end, you will have the skills to build and manage a compliant confined space program at your worksite.

    Explains physiological effects of low and high oxygen concentrations and the conditions that create them. Establishes acceptable entry thresholds used in permit evaluation.

  • Lesson 2 • Toxic Atmosphere Identification

    Identifies common toxic gases found in confined spaces and their permissible exposure thresholds. Prepares students to select appropriate detection methods for each contaminant.

  • Lesson 3 • Continuous Monitoring During Entry

    Addresses how atmospheric conditions change during work and the protocols for ongoing monitoring. Connects real-time data to evacuation triggers and permit suspension criteria.

  • Lesson 4 • Gas Detection Instruments and Calibration

    Teaches instrument selection, bump testing, calibration, and proper sampling technique. Ensures accurate readings that support safe entry decisions.

  • Lesson 5 • Flammable and Combustible Atmospheres

    Covers lower and upper explosive limits, ignition sources, and conditions that produce flammable atmospheres. Links monitoring results to hot-work and ventilation decisions.

Chapter 3See details

Ventilation Strategies for Confined Spaces

  • Lesson 1 • Mechanical Ventilation Equipment

    Covers blower types, duct sizing, placement, and power source considerations for mechanical ventilation. Enables correct equipment selection for varied space configurations.

  • Lesson 2 • Ventilation Plan Development

    Guides students through documenting a site-specific ventilation plan as part of the permit process. Integrates monitoring data, equipment specs, and contingency measures into one document.

  • Lesson 3 • Principles of Confined Space Ventilation

    Explains airflow dynamics, dilution versus displacement ventilation, and how space geometry affects effectiveness. Provides the physical basis for all ventilation planning decisions.

  • Lesson 4 • Ventilation for Flammable Atmospheres

    Addresses purging, inerting, and continuous dilution techniques for spaces with flammable gases. Links ventilation outcomes to LEL monitoring thresholds before entry is permitted.

Chapter 4See details

Permit-Required Confined Space Program

  • Lesson 1 • Permit Elements and Completion

    Details every required element of a confined space entry permit and the sequence for completing it. Ensures students can produce a legally compliant, operationally useful permit.

  • Lesson 2 • Permit Review and Annual Audit

    Explains post-entry permit review, program auditing, and corrective action processes. Builds continuous improvement habits that keep the program current and effective.

  • Lesson 3 • Space Inventory and Identification

    Establishes the process for identifying, surveying, and labeling all confined spaces on a site. Creates the foundational inventory that drives permit issuance and hazard control planning.

  • Lesson 4 • Hazard Control and Isolation

    Covers lockout/tagout, blanking, blinding, and line breaking as methods to eliminate permit space hazards. Connects isolation procedures to permit completion and entry authorization.

  • Lesson 5 • Roles and Responsibilities

    Defines the duties of the entry supervisor, authorized entrant, and attendant for each phase of entry. Clarifies accountability chains that prevent role confusion during emergencies.

Chapter 5See details

Personal Protective Equipment for Confined Spaces

  • Lesson 1 • Respirator Fit Testing and Donning

    Teaches qualitative and quantitative fit test methods, donning sequence, and seal checks. Ensures respirators provide rated protection when worn in the field.

  • Lesson 2 • Respiratory Protection Selection

    Covers air-purifying and supplied-air respirator types, assigned protection factors, and selection logic. Prepares students to choose the correct respirator for each atmospheric hazard scenario.

  • Lesson 3 • Body and Head Protection

    Addresses hard hats, chemical-resistant suits, gloves, and footwear selection for confined space work. Links PPE choices to specific physical and chemical hazards identified on the permit.

  • Lesson 4 • PPE Inspection and Maintenance

    Establishes pre-use inspection criteria, storage requirements, and retirement criteria for all confined space PPE. Prevents equipment failure caused by undetected damage or degradation.

Chapter 6See details

Entry Procedures and Attendant Duties

  • Lesson 1 • Conditions Requiring Evacuation

    Identifies the specific conditions that require immediate evacuation and the attendant's authority to order it. Connects permit suspension criteria to the attendant's real-time decision-making.

  • Lesson 2 • Pre-Entry Briefing and Authorization

    Covers the entry supervisor's pre-entry briefing, permit sign-off, and final authorization steps. Establishes the communication baseline that all team members rely on during entry.
