Exam objective
Core 2 4.0: Safety and Environment Controls
Safety and Environment Controls for A+
This A+ topic covers technician-level safety controls and local environmental controls that protect people and equipment during hardware service. It focuses on actions a technician must take or recognize: ESD controls and component handling, basic electrical and personal safety, workspace control (storage and cable management), disposal-handling guidance linked to MSDS, local environmental factors (temperature, humidity, ventilation, dust), and basic power-event protection (UPS vs surge suppressor).

Common mistakes to avoid
- 'If I'm wearing rubber-soled shoes I'm safe' is false; typical footwear can insulate rather than dissipate charge. Grounding the technician or the work surface is the correct control.
- Confusing ESD grounding with electrical safety grounding: ESD straps ground static; electrical safety requires removing power and using certified safe procedures.
- Confusing neatness with safety: a visually neat bundle can still cause strain on connectors if it is forced into tight bends. - Using permanent cable ties where frequent service is required; Velcro is preferable for serviceable connections.
- Confusing disposal handling with data destruction: proper disposal handling ensures safety and environmental compliance; data sanitization and destruction methods are separate topics.
