Questions and Answers

1.

Oil or grease in contact with __________ will cause and explosion.
- A.
  
  A gas cylinder
- B.
  
  Acetylene
- C.
  
  Compressed oxygen
- D.
  
  Combustible materials
Correct Answer
C. Compressed oxygen

Explanation
When oil or grease comes into contact with compressed oxygen, it can cause an explosion. This is because compressed oxygen supports combustion, making it highly reactive with flammable substances. When oil or grease mixes with oxygen under pressure, it increases the likelihood of ignition and can lead to a violent explosion. Therefore, it is crucial to prevent any oil or grease from coming into contact with compressed oxygen to ensure safety in industrial settings or any other environment where compressed oxygen is used.

2.

Flash burns are caused by exposing your eyes to ____________.
- A.
  
  Ultraviolet light
- B.
  
  Oxygen and acetylene
- C.
  
  Petroleum products
- D.
  
  Zing oxide fumes
Correct Answer
A. Ultraviolet light

Explanation
Flash burns are caused by exposing your eyes to ultraviolet light. Ultraviolet light is a type of radiation that is not visible to the human eye. When the eyes are exposed to high levels of ultraviolet light, such as from a welding torch or a bright flash, it can cause damage to the cornea and the retina. This can result in symptoms such as pain, redness, blurred vision, and sensitivity to light. It is important to protect the eyes from ultraviolet light by wearing appropriate eye protection, such as safety goggles or welding masks.

Rate this question:
3.

A ___________ is attached to a cylinder valve to reduce the high cylinder pressure to the require lower working pressure.
- A.
  
  Safety valve
- B.
  
  Regulator
- C.
  
  Torch assembly
- D.
  
  Compression hose
Correct Answer
B. Regulator

Explanation
A regulator is attached to a cylinder valve to reduce the high cylinder pressure to the required lower working pressure. A regulator is a device that controls the flow and pressure of a gas or liquid. In this case, it is used to decrease the pressure from the cylinder to a level that is suitable for the intended application, ensuring safety and efficient operation.

Rate this question:
4.

A confined space _____________..
- A.
  
  Has a limited amount of ventilation
- B.
  
  Has no means of entry
- C.
  
  Is too small to work in
- D.
  
  May be entered by untrained employees
Correct Answer
A. Has a limited amount of ventilation

Explanation
A confined space is a space that has limited ventilation, meaning there is not enough fresh air circulating in the area. This can be dangerous as it can lead to a lack of oxygen or the buildup of harmful gases, posing a risk to anyone entering the space. Therefore, it is important to take precautions and ensure proper ventilation when working in confined spaces to maintain a safe environment.

Rate this question:
5.

All internal combustion engines give off a deadly odorless, tasteless, invisible gas called __________ as part of their exhaust.
- A.
  
  Carbon tri-oxide
- B.
  
  Carbon monoxide
- C.
  
  Carbon dioxide
- D.
  
  Carbon cyanide
Correct Answer
B. Carbon monoxide

Explanation
Carbon monoxide is a deadly gas that is produced as part of the exhaust of all internal combustion engines. It is odorless, tasteless, and invisible, making it difficult to detect without proper monitoring equipment. Carbon tri-oxide, carbon dioxide, and carbon cyanide are not gases typically produced by engines and do not pose the same level of danger as carbon monoxide.
