Which types of clothing are likely to generate a static charge?

Wool
Cotton
Silk
All of the above

Correct Answer

A. All of the above

Explanation

Wool, cotton, and silk are all likely to generate a static charge. These materials have the ability to rub against other surfaces and create friction, which leads to the buildup of static electricity. When two materials with different electrical properties come into contact and then separate, electrons can be transferred, resulting in a static charge. Therefore, all three types of clothing mentioned can generate a static charge.

Which recommendation should be followed first when a fire in the workplace is out of control?

Try to use the elevators or lifts to get out of the building
Try to get out of the room and contact the emgergency services
Open all windows and jump for it
Run around screaming until someone punches you in the face

Correct Answer

A. Try to get out of the room and contact the emgergency services

Explanation

When a fire in the workplace is out of control, the first recommendation that should be followed is to try to get out of the room and contact the emergency services. This is the most logical and practical course of action to ensure personal safety and to alert the appropriate authorities for immediate assistance. Trying to use elevators or lifts may be dangerous as they could malfunction or become inaccessible during a fire. Opening windows and jumping is also extremely risky and should be avoided. Running around screaming is not a helpful or productive response in such a situation.

Which of these conditions refers to a dramatic increase in voltage, which is usally caused by lightening?

Pulse
Sag
Call the techies my PC is fried!
Spike

Correct Answer

A. Spike

Explanation

A spike refers to a dramatic increase in voltage, usually caused by lightning. This sudden surge in voltage can potentially damage electrical equipment, including computers. It is important to protect electronic devices from spikes by using surge protectors or unplugging them during storms to prevent damage.

What does ESD stand for?

Electrostatic detectives
Electrostatic dymanics
Electrostatic dummies
Electrostatic discharge

Correct Answer

A. Electrostatic discharge

Explanation

ESD stands for Electrostatic Discharge. Electrostatic discharge refers to the sudden flow of electricity between two objects with different electrical potentials. It occurs when there is a buildup of static electricity on one object and it discharges to another object. ESD can cause damage to electronic components and devices, which is why measures such as grounding and ESD protection are important in handling sensitive electronics.

What are the major causes of noise?

Generators and Lightening
Squeeky doors
Chris Moyles
Christmas bells

Correct Answer

A. Generators and Lightening

Explanation

Generators and lightning are major causes of noise because they both produce loud and disruptive sounds. Generators, especially industrial ones, are known for their loud operation and can generate a constant noise that can be heard from a distance. Lightning, on the other hand, produces thunder, which is a loud noise caused by the rapid expansion of air due to the intense heat of the lightning bolt. Both generators and lightning can create significant noise pollution and can be disruptive to the surrounding environment.

Which of these is a fact sheet that summarises information about material identicication?

MSFS
MIFS
MILFS
MSDS

Correct Answer

A. MSDS

Explanation

MSDS stands for Material Safety Data Sheet, which is a fact sheet that provides essential information about a particular material or substance. It summarizes important details such as the material's identification, hazards, handling and storage instructions, emergency procedures, and more. MSDSs are commonly used in workplaces to ensure the safe handling and use of materials, and they are an important resource for employees to understand the potential risks associated with a substance and how to mitigate them.

Which screwdriver should be used to remove screws that have a star-like depression on top?

Torox
Flat head
Hex driver
Bus driver

Correct Answer

A. Torox

Explanation

A Torox screwdriver should be used to remove screws that have a star-like depression on top. This type of screwdriver has a tip that matches the star-like shape of the screw, allowing for a secure and precise fit. Using any other type of screwdriver, such as a flat head or hex driver, may result in damage to the screw or the tool itself. A "Bus driver" is not a type of screwdriver and is not relevant to this question.

Which command is used to prepare a hard drive to store information?

Defrag
Format
Boot Disk
Boot Computer

Correct Answer

A. Format

Explanation

The command "Format" is used to prepare a hard drive to store information. This command erases all the data on the hard drive and sets up the file system, making it ready to store new information. It creates a new file allocation table and directory structure, allowing the operating system to organize and access the data efficiently.
