Why High Voltage Safety Matters
Electrical hazards remain among the most serious occupational risks in the utility, energy, and construction industries. Understanding and controlling these hazards is not optional — it is a professional and legal imperative.
Annual Fatalities
Electrical incidents claim over 1,000 lives in the Americas each year, with many more resulting in permanent injury.
Arc Flash Losses
Estimated annual cost of arc flash incidents globally, including medical, legal, and productivity losses.
Preventable
The vast majority of serious electrical incidents are preventable with proper training, PPE, and safe work procedures.
Arc Flash Energy
Arc flash events can release up to 30,000 amperes of fault current — enough to cause fatal burns and explosive blasts.
Course Overview
The High Voltage Safety & Risk Control for Lineworkers programme is a comprehensive, six-week course built on international safety standards, including NFPA 70E, IEEE, and OSHA frameworks, adapted to Caribbean operational environments. Participants gain both theoretical grounding and hands-on practical experience across seven structured modules.
By course completion, participants will hold a Certificate of Completion from ASTI and be equipped to contribute meaningfully to a culture of electrical safety within their organisations.

Overview of generation, transmission (33kV–400kV), and distribution (11kV–33kV) infrastructure as found across the Caribbean grid.
Utility Infrastructure & Equipment
Identification of poles, towers, transformers, switchgear, substations, and associated components and their operational roles.
Hazard Identification in the Field
Systematic approach to identifying electrical hazards during site surveys and pre-task planning activities.
Electrical Hazard Recognition
Understanding the specific mechanisms by which electricity injures and kills is fundamental to preventing incidents. This module covers the five primary electrical hazards encountered in high-voltage environments, using technical diagrams and real-world case studies to reinforce recognition and response.
Each hazard type requires a distinct set of controls and PPE selections. Correct hazard identification is the first — and most critical — step in preventing electrical injuries and fatalities on the job site.
Personal Protective Equipment (PPE)
Proper PPE selection, inspection, and use forms the last line of defence against electrical hazards. This module provides participants with the knowledge to select the correct PPE for every electrical task — and the discipline to never compromise on its use.
PPE Selection
Matching PPE category to arc flash incident energy levels and voltage exposure according to NFPA 70E / IEC 60900 standards.
Inspection Procedures
Pre-use and periodic inspection protocols for electrical-rated gloves, sleeves, blankets, and arc-rated clothing to identify damage and degradation.

Risk Assessment & Job Hazard Analysis
Systematic risk assessment is the cornerstone of a safe electrical worksite. This module provides participants with a structured methodology for identifying hazards, evaluating risks, and implementing effective controls before any high-voltage work begins.
Assessment Process
Hazard Identification
Identify all potential electrical, physical, and environmental hazards present at the work location.
Risk Ranking
Evaluate likelihood and consequence using a risk matrix to prioritise hazards requiring immediate control.
Job Safety Analysis (JSA)
Break each task into steps, identify hazards at each step, and specify the required control measure.
Control Measures & Work Planning
Apply the Hierarchy of Controls — elimination, substitution, engineering, administrative, and PPE.
Risk Matrix
Lockout / Tagout Procedures
Lockout/Tagout (LOTO) is one of the most critical safety procedures for anyone working on electrical systems. This module provides comprehensive training in energy isolation and control practices that prevent the unexpected re-energisation of equipment during maintenance and repair operations.
