    Authorized Gas Tester Level 1

    Course Objectives: 

    • Worksites contain a wide variety of Safety and Health Hazards. In terms of worksite hazards, it is important to classify major hazards that are known to cause further harm in the workplace if they are not assessed. Gas Testing is the facilitation of detecting and measuring the concentrations of various, often hazardous, or otherwise unwanted components in indoor air as well as fuel, process, and waste gases. Supervisors and Line Managers, therefore, need to have a higher level of tasks and responsibilities in areas that contain highly dangerous gases with the potential to harm workers and damage property. 
    • The Authorized Gas Tester training program is designed to meet the initial training and knowledge assessment requirements for personnel preparing to work as Authorized Gas Testers. Authorized Gas Testers in the Level 1 Program shall provide a comprehensive overview of Gas Testing hazards, procedures, different gas detectors, and their mechanisms, and the relevant control measures. Therefore, the aim and objectives of the Authorized Gas Tester training program are to ensure that personnel preparing for a gas tester role are equipped with the knowledge to conduct gas tests for oxygen levels, and flammable, and toxic gases safely. 
    Course Aims: 
    The following points shall be discussed in the course:
    • Understanding general Health and Safety Hazards of gases
    • The importance, scope, and steps of the Permit to Work System 
    • Roles and responsibilities of Line Supervisors in Gas Testing Procedures
    • Determining gas/atmosphere types.
    • Understanding environmental harm related to gas exposure
    • Understanding toxic risk to gas exposure 
    • Understanding flammable gases and their risk exposures 
    • How a flammable gas or vapor clouds arrive at the work site 
    • Different types of gas test equipment. 
    • Selecting and calibrating equipment appropriate for the workplace.
    • Determining gas testing regime/sampling patterns.
    • Identifying hazards from possible atmosphere contaminants. 
    • Implementing hazard control measures, including the use of PPE. 
    • Using gas testing equipment to test gas. 
    • Interpreting and reporting readings. 
    • How to monitor gas.
