4.4 Using Common Safety Procedures

This article provides an overview of essential safety procedures for handling electronic components and maintaining a safe workspace, as required for the CompTIA A+ exam.

CompTIA A+ Exam Domain: Domain 4.4 - Given a scenario, use common safety procedures.

Electrostatic Discharge (ESD) Protection

ESD Straps

• Purpose: Prevents static electricity from damaging sensitive components.

• Usage:

  • Wear the strap around your wrist.

  • Attach the grounding clip to an unpainted, grounded metal surface (e.g., PC chassis).

  • Ensure constant contact with the strap while handling internal components.

ESD Mats

• Purpose: Provides a grounded surface to dissipate static electricity.

• Usage:

  • Place the mat on a workstation before handling components.

  • Connect the mat to a proper ground source.

  • Store sensitive parts on the mat when not in use.

Equipment Grounding

• Purpose: Prevents electrical hazards by ensuring proper grounding of equipment.

• Usage:

  • Ensure that outlets and surge protectors are properly grounded.

  • Use three-pronged power cords.

  • Ground all electrical components to prevent surges.

Proper Power and Component Handling

Proper Power Handling

• Ensure devices are unplugged before performing maintenance.

• Use a surge protector or UPS (Uninterruptible Power Supply) to prevent voltage spikes.

• Follow manufacturer guidelines when replacing power supplies or working inside a system.

Proper Component Handling and Storage

• Hold components by the edges to avoid damaging circuits.

• Avoid touching exposed pins or connectors.

• Store sensitive components in antistatic bags when not in use.

Antistatic Bags

• Purpose: Shields electronics from static electricity.

• Usage:

  • Store RAM, CPUs, GPUs, and motherboards in antistatic bags.

  • Keep parts in their original packaging if possible.

  • Never store components on metal surfaces without proper insulation.

Compliance with Government Regulations

• Follow OSHA (Occupational Safety and Health Administration) guidelines for workplace safety.

• Adhere to EPA (Environmental Protection Agency) regulations for electronic waste disposal.

• Dispose of batteries and hazardous materials in accordance with local and federal laws.

Personal Safety Practices

Disconnect Power Before Repairing a PC

• Always unplug power sources before opening a device.

• Press and hold the power button for a few seconds to discharge remaining power.

Lifting Techniques

• Use proper lifting posture to avoid injuries:

  • Bend at the knees, not the waist.

  • Keep heavy objects close to your body.

  • Use a partner or mechanical aid for bulky equipment.

Electrical Fire Safety

• Never use water on an electrical fire.

• Use a Class C fire extinguisher for electrical fires.

• Ensure work areas have accessible fire extinguishers.

Safety Goggles

• Wear safety goggles when handling compressed air, cutting cables, or working with hazardous materials.

Air Filtration Mask

• Use an air mask when cleaning systems with dust buildup or handling chemicals.

• Prevents inhalation of harmful particles from compressed air or thermal paste.

Final Thoughts

Following safety best practices ensures a secure and efficient working environment. The CompTIA A+ exam evaluates an IT professional’s ability to apply ESD protection, handle power and components safely, comply with regulations, and maintain personal safety while performing technical tasks.
