Which statement about risk assessment in electrical workplaces is most accurate?

Which statement about risk assessment in electrical workplaces is most accurate?

• A. It is a purely qualitative exercise with no standards
• B. It is performed only during commissioning and not during design
• C. It identifies hazards, evaluates risks, and implements controls; guided by NFPA 70E and ISO 31000
• D. It requires only management approval and no field input

Answer: (C)

Risk assessment in electrical workplaces is about systematically identifying hazards, evaluating how likely they are and how severe the consequences could be, and then applying controls to reduce risk. It’s guided by recognized standards, notably NFPA 70E for electrical safety in the workplace and ISO 31000 for general risk management, which provide the framework and specific practices for handling electrical risks. Start by listing potential hazards such as electric shock, arc flash, arc blast, fire, and thermal injuries, taking into account the specific tasks, equipment, voltage levels, and environmental conditions. Then assess the risk by weighing both the probability of an incident and the potential severity, which helps decide where to focus controls. Implement a mix of measures: engineering controls (like proper guarding, interlocks, and safe equipment design), administrative controls (such as safe work procedures, permits, and training), and appropriate personal protective equipment. Finally, keep the assessment current by reviewing it regularly and whenever conditions change, and involve workers who actually perform the tasks, since field experience can reveal risks not evident from design alone. This ongoing, standards-guided, collaborative approach is what makes the statement the most accurate.
