ASSIGNMENT#1
1) Research and compile a list of safety terms (signs, symbols, labels, and
jargon) commonly used in the field of Computer engineering or Computer
lab.
2) Provide a definition and explanation for each term
3) Include examples of how these terms are applied in real-world scenarios.

Following are the safety terms and their symbols :

1) Food and Drink Prohibited

• Definition: This symbol indicates that eating or drinking is not allowed in

the designated area.

• Explanation: Prohibiting food and drinks prevents spills that can damage
sensitive electronic equipment and reduces contamination risks.

• Location in Lab: Commonly placed at entrances or within computer labs,

near workstations, or around equipment like servers and PCs.

• Real-world Application: In computer labs, food and drinks are

prohibited to avoid accidental damage to keyboards, circuit boards, or other
components due to liquid spills.
2) First Aid Symbol

• Definition: Indicates the location of first aid supplies or a medical station

where basic medical treatment can be administered.

• Explanation: This symbol helps quickly locate first aid kits or assistance
during injuries or emergencies in the lab.

• Location in Lab: Found near the entrance, safety stations, or close to

high-risk areas such as near soldering stations or equipment that could cause
injury.

• Real-world Application: In a computer lab, if someone gets a small cut

or burn while working on hardware, they can quickly access first aid
supplies for immediate treatment.

3) High Voltage Symbol

 • Definition: Warns of areas or equipment with high electrical voltage that
poses a risk of electrical shock or electrocution.
• Explanation: The symbol alerts individuals to the danger of exposure to
high voltage, ensuring they take proper precautions.

• Location in Lab: Found near power supplies, server racks, or electrical

distribution panels where high-voltage equipment is used.

• Real-world Application: In computer labs or data centers, technicians

working on server equipment are alerted to areas with high-voltage lines,
ensuring they wear appropriate protective gear or follow safety protocols.

4) Restricted Entry Symbol

• Definition: Indicates that access to a particular area is restricted to

authorized personnel only.

• Explanation: This sign helps control access to sensitive or hazardous

areas, ensuring only trained or authorized individuals enter.

• Location in Lab: Typically found at the entrance to server rooms, data

centers, or sections with specialized equipment.

• Real-world Application: In computer labs with valuable or sensitive

equipment, restricted entry signs ensure only qualified personnel, such as IT
staff or engineers, can access certain areas to prevent accidents or
unauthorized tampering.
5) No Open Flam Symbol

• Definition: This symbol indicates that open flames, such as candles or

lighters, are prohibited in the area.

• Explanation: It prevents fire hazards, especially in environments with

flammable materials or sensitive electronic equipment.

• Location in Lab: Found near areas with flammable liquids, solvents, or

delicate equipment like computer components.

• Real-world Application: In computer labs or workshops, this sign

ensures that open flames are not used near soldering stations or chemical
solvents that could ignite and cause fires.

6) Fire Extinguisher Symbol

• Definition: Indicates the location of a fire extinguisher, providing

information on its type and usage.
 • Explanation: This symbol alerts individuals to the presence of fire safety
equipment, essential for quick action in the event of a fire.

• Location in Lab: Typically placed near exits, in hallways, or close to

equipment that poses a fire risk, such as electrical appliances or soldering
stations.

• Real-world Application: In a computer lab, if a fire starts due to

overheating equipment, the fire extinguisher symbol guides individuals to
the nearest extinguisher, enabling rapid response to control the situation and
prevent further damage.

7) Electric Hazard Symbol

• Definition: Warns of potential risks associated with electrical equipment,

including the risk of electric shock or arc flash.

• Explanation: This symbol indicates areas where electrical hazards are

present, urging individuals to exercise caution.

• Location in Lab: Commonly found near high-voltage equipment, power

supplies, or in areas where electrical maintenance is performed.

• Real-world Application: In a computer lab or data center, the electrical

hazard symbol alerts technicians to take precautions, such as wearing
insulated gloves or using insulated tools when working on live circuits to
prevent accidents or injuries.
8) Grounding Symbol

• Definition: Indicates that electrical equipment or devices must be properly

grounded to prevent electrical shock and ensure safe operation.

• Explanation: This symbol highlights the importance of connecting

electrical devices to the earth to safely dissipate excess electricity and avoid
hazards.

• Location in Lab: Found on electrical outlets, power supplies, and near

equipment that requires grounding, such as computers, servers, and
laboratory instruments.

• Real-world Application: In computer labs, grounding is essential for

preventing static electricity buildup and protecting sensitive equipment.
Technicians use grounded outlets and wear anti-static wristbands when
handling circuit boards to ensure safety and minimize the risk of damage.

9) Surge Protection Symbol

 • Definition: Indicates that a device or outlet is equipped with surge
protection to guard against voltage spikes that can damage electronic
equipment.
• Explanation: This symbol informs users that the connected devices are
protected from sudden increases in electrical voltage, which can occur
during storms or power fluctuations.

• Location in Lab: Typically found on power strips, surge protector units,

or near electrical outlets designated for sensitive electronic equipment.

• Real-world Application: In computer labs, surge protection is crucial

for safeguarding servers and computers against damage caused by power
surges, ensuring the longevity and reliability of the equipment, especially
during electrical storms or when heavy machinery is used.

10) Circuit Breaker Symbol

• Definition: Indicates the location of a circuit breaker, which is a safety

device that automatically stops the flow of electricity in a circuit during
overloads or faults.

• Explanation: This symbol serves to inform users of the presence of a

circuit breaker, ensuring they know where to reset or cut power in case of an
electrical issue.

• Location in Lab: Commonly found on electrical panels, walls, or near

areas with heavy electrical equipment, such as server rooms or workstations.

• Real-world Application: In a computer lab, if there is a power surge or

short circuit, the circuit breaker will trip to prevent equipment damage and
 potential fires. Technicians can quickly reset the breaker to restore power
safely, protecting both the equipment and users.

11) Manual Handling Safety Symbol

• Definition: Indicates areas or tasks where manual handling of heavy

objects is involved and highlights the need for proper lifting techniques.

• Explanation: This symbol reminds users to lift heavy equipment correctly

to prevent injuries, such as strains or sprains.

• Location in Lab: Typically placed near storage areas for heavy

equipment, such as server racks or large components that require lifting.

• Real-world Application: In a computer lab, when technicians are

required to move heavy servers or equipment, the manual handling safety
symbol prompts them to use team lifting or equipment like dollies, reducing
the risk of injury while transporting items.
