Midterms Flashcards
refer to unsafe conditions or potential dangers that pose a risk of electric shock, arc flash, or fire explosion resulting from electrical energy being present or misused.
Electrical hazards
Caused by direct contact with live wires or components.
Electric Shock
Occur when unintended connections are made in electrical circuits, causing excess current flow.
Short Circuits
A sudden release of energy due to a rapid increase in electrical current, potentially leading to explosive bursts of heat and light.
Arc Flash
Common Types of Electrical Hazards in Computer Engineering Environments
Electric Shock
Arc Flash
Electrical Fires
Overloads & Short Circuit
High Voltage
What are the Potential Risks Associated with Electrical Hazards
Injury or Death: Direct exposure to electrical currents can lead to severe injuries or fatal accidents.
Burns: Arc flashes can cause thermal burns or ignite flammable materials.
Equipment Damage: Short circuits and overheating can damage electrical and electronic equipment.
Fires: Electrical faults can lead to fires, risking property and personal safety.
Downtime: Equipment failure due to electrical hazards can lead to significant operational disruptions.

Safety practices in handling electrical equipment
- Guidelines for safe handling of electrical equipment
- Importance of proper insulation and grounding
- Procedures for safe installation and maintenance of electrical components
Guidelines for Safe Handling of Electrical Equipment:
- Always ensure that electrical equipment is de-energized before handling. This involves turning off power at the source and testing equipment to confirm it’s not live.
- Use appropriate personal protective equipment (PPE), such as insulated gloves, safety goggles, and flame-resistant clothing to minimize risks.
- Maintain a clear understanding of the equipment’s user manual and safety instructions to avoid misuse.
Importance of Proper Insulation and Grounding:
- Insulation: Adequate insulation on wires and components prevents accidental contact with live parts and minimizes shock hazards. Regularly inspect insulation for wear and damage.
- Grounding: Proper grounding of electrical systems provides a safe path for fault currents to dissipate, significantly reducing the risk of shock and electrical fires. This includes grounding conductors and equipment to ensure that fault conditions are safely handled.
Procedures for Safe Installation and Maintenance of Electrical Components:
- Follow established procedures and local electrical codes during installation to ensure compliance with safety standards.
- Conduct routine inspections and maintenance to identify potential hazards such as loose connections, frayed wires, or overloaded circuits.
- Document any modifications or maintenance activities to maintain consistency and safety in future operations.

Overview of Electrical Safety Standards and Regulations:
Electrical safety standards and regulations provide guidelines to ensure safe practices in the design, installation, operation and maintenance of electrical systems, particularly in computer engineering contexts. These standards aim to protect individuals and property from electrical hazards through structured safety protocols.
Examples of Relevant Standards:
- IEEE (Institute of Electrical and Electronics Engineers): Provides standards related to the design and implementation of electrical systems, emphasizing the safety of electrical equipment and installations.
- ANSI (American National Standards Institute): Oversees the development of consensus standards for a wide range of products, including those in electrical engineering, ensuring they meet safety and efficiency criteria.
- NFPA (National Fire Protection Association): Develops codes and standards to reduce the risk of fire and electrical hazards, particularly the National Electrical Code (NEC), which outlines safe electrical installation practices.
