Introduction
The programme “High-Voltage and Electrical Hazard Prevention” develops professional practice in Occupational Health and Safety. It connects the subject with workplace challenges by examining existing evidence and practices and choosing methods appropriate to the organization and its available resources.
The learning progresses from electrical systems, control, and operational efficiency to process safety, barriers, and management of change, with practical work on occupational safety, risk assessment, and prevention, risk assessment, controls, and response, crisis management, communication, and response. Participants prepare outputs to support workplace application and review the quality and results of implementation.
Learning objectives
- Read a training electrical system and identify inspection, protection, and control requirements in an application related to “High-Voltage and Electrical Hazard Prevention”.
- Prepare a work risk assessment and prevention and response plan based on the hierarchy of controls.
- Prepare a risk register connecting causes, consequences, controls, and treatment responsibilities.
- Prepare a crisis response and communication plan covering roles, messages, and escalation.
- Analyze an operational hazard scenario and review barriers and change control responsibilities.
Learning areas
1. Electrical Systems, Control, and Operational Efficiency
- Read a training single-line or control diagram, identifying supply, loads, protection and measurement devices, and system boundaries.
- Analyze load, power quality, and efficiency requirements and fault indicators, checking data accuracy and conformity with equipment specifications.
- Identify the roles of protection, earthing, isolation, coordination, and control, referring settings and execution to specialists and approved technical references.
- Design an inspection and testing checklist covering criteria, tools, responsibilities, safety procedures, and permits without instructions for intervention on an energized circuit.
- Prepare a technical report comparing readings with approved limits and presenting possible causes, proposed actions, and approval requirements before execution. The application examines a case related to “High-Voltage and Electrical Hazard Prevention”.
2. Occupational Safety, Risk Assessment, and Prevention
- Identify task hazards, exposed people, and site conditions, gathering information from observations, records, and equipment instructions.
- Estimate the risk level and select appropriate controls from elimination, substitution, engineering controls, administrative controls, and personal protective equipment.
- Review work procedures, permits, isolation, communication, and supervision according to the task, and define responsibility for stopping unsafe work.
- Analyze an incident or near miss using facts and evidence, examining systemic causes and failed controls beyond blaming individuals.
- Prepare a tabletop emergency exercise and an inspection, awareness, and follow-up plan, assigning field execution to qualified personnel under approved procedures.
3. Risk Assessment, Controls, and Response
- Define the work context, objectives, and assessment boundaries, and distinguish the risk source, potential event, and effects on results.
- Gather risks from processes, data, past incidents, and interviews with responsible staff, and document causes and existing controls.
- Estimate likelihood and impact using stated criteria, and review control effectiveness to determine residual risk levels.
- Select a response proportionate to the risks, resources, and authority, and specify the owner, deadline, and early warning indicator.
- Test a scenario involving changing circumstances, update the risk register, and present material risks and required decisions to the appropriate authority.
4. Crisis Management, Communication, and Response
- Identify crisis scenarios, warning indicators, and effects on people, services, and reputation, and define response activation thresholds.
- Allocate crisis team roles, decision-making authority, and escalation paths, and establish a mechanism for collecting and updating verified information.
- Draft an initial message explaining confirmed facts, actions, and update channels, avoiding speculation or disclosure of sensitive information.
- Run a simulation involving changing information, time pressure, and multiple parties, recording decisions, their rationale, and their timing.
- Conduct a post-crisis review comparing the plan with execution, and define improvement actions, owners, and dates for retesting readiness.
5. Process Safety, Barriers, and Management of Change
- Identify sources of hazardous materials and energy and process boundaries, distinguishing process safety from individual occupational safety in the case presented.
- Analyze the sequence, causes, and consequences of a hazardous event, and identify preventive and mitigating barriers and evidence for verifying their readiness.
- Review work permits, isolation, and coordination among parties under facility procedures, and identify hold points requiring specialist approval.
- Prepare a change request identifying its rationale, risks, and effects on documents, training, and emergencies, with technical review before implementation.
- Conduct a tabletop exercise involving a hypothetical barrier failure or leak, and document escalation and response actions, lessons, and the subsequent verification plan.
Practical outputs
- A functional diagram, checklist, and preliminary analysis of electrical system performance.
- A task risk assessment and an inspection, training, and response plan.
- A risk register, control matrix, and prioritized treatment plan.
- A crisis plan, decision register, initial statement template, and simulation exercise.
- A register of risk scenarios and barriers, and an operational change review plan.
Who should attend
- Engineers, technicians, supervisors and operations staff whose work relates to the programme subject.
- Managers and teams working in occupational health and safety, according to their practical responsibilities.
- Professionals responsible for applying the outputs of “High-Voltage and Electrical Hazard Prevention” within their organizations.
