What should you always wear when dealing with PCB replacement?

1. Flame-resistant gloves

2. Heavy boots

3. Grounding wrist strap

4. High-visibility vest

The correct answer is: Flame-resistant gloves

When dealing with PCB (Printed Circuit Board) replacement, the most critical consideration is the risk of electrical shock and the safe handling of electronic components. Wearing flame-resistant gloves provides essential protection against risks associated with handling live circuits or components that may still retain a charge. These gloves are designed to protect the skin from potential burns or injuries caused by unexpected electrical discharges, making them a vital piece of personal protective equipment in such scenarios. Other equipment like heavy boots or high-visibility vests have their own safety purposes but are less critical to the specific context of dealing directly with PCBs. Grounding wrist straps are useful for preventing electrostatic discharge (ESD), especially when sensitive electronic components are involved, but they do not offer the same level of protection against electrical hazards that flame-resistant gloves provide. Thus, the choice of flame-resistant gloves as the primary protective gear highlights the importance of safety while handling potentially hazardous electrical components.
