L.P. Book HAZMAT / Lesson #7 HAZMAT – Monitoring Methods & Equipment

1.

The first responder must be able to detect the presence of a ___________ ____________ at the scene of an emergency
- A.
  
  Command Post
- B.
  
  Fire Engine
- C.
  
  Hazardous Material
- D.
  
  Re-hab area
Correct Answer
C. Hazardous Material

Explanation
The first responder must be able to detect the presence of hazardous material at the scene of an emergency. This is important because hazardous materials can pose significant risks to both the responders and the public. Identifying the presence of hazardous material allows the responders to take the necessary precautions and implement appropriate safety measures to mitigate the risks associated with its presence.

Detection can usually be achieved by observing the leaking container from a _______ distance outside the spill area
- A.
  
  Close
- B.
  
  Safe
- C.
  
  Undefined
- D.
  
  All of the above
Correct Answer
B. Safe

Explanation
Detection can usually be achieved by observing the leaking container from a safe distance outside the spill area. This means that in order to detect any leaks or spills, it is important to maintain a distance that ensures the safety of the observer. By staying at a safe distance, one can effectively observe and identify any leaking containers without putting themselves at risk of being exposed to hazardous substances or accidents.

Examples of methods for detecting hazardous materials include: Physical signs of leaking containers, Labels, Placards, and
- A.
  
  Observing container shapes
- B.
  
  Tasting product on the ground
- C.
  
  Drawing in a big breath of air
- D.
  
  None of the above
Correct Answer
A. Observing container shapes

Explanation
Observing container shapes can be a method for detecting hazardous materials because certain shapes or designs of containers can indicate the presence of hazardous substances. For example, containers with specific markings, symbols, or colors may be used to store or transport hazardous materials. By observing the shape and design of a container, one can identify potential hazards and take appropriate precautions.

Physical signs of leaking containers include:
- A.
  
  Vapors
- B.
  
  Frost
- C.
  
  Chemical reactions
- D.
  
  All of the above
Correct Answer
D. All of the above

Explanation
The correct answer is "All of the above". This is because physical signs of leaking containers can include vapors, frost, and chemical reactions. Vapors can be seen as gases or fumes escaping from the container. Frost can form on the outside of the container due to the escaping gas cooling the surrounding air. Chemical reactions may occur when the leaked substance comes into contact with other substances, causing visible changes such as color changes or the formation of bubbles. Therefore, all of these signs can indicate a leaking container.

Monitoring instruments may be required to determine specific
- A.
  
  Flammability
- B.
  
  Toxicity
- C.
  
  Oxygen-deficient concentrations
- D.
  
  All of the above
Correct Answer
D. All of the above

Explanation
Monitoring instruments may be required to determine specific flammability, toxicity, and oxygen-deficient concentrations in order to ensure safety in various environments. Flammability monitoring instruments can detect the presence of flammable gases or vapors, helping to prevent fires or explosions. Toxicity monitoring instruments can measure the concentration of harmful substances in the air, protecting individuals from exposure to toxic fumes. Oxygen-deficient concentrations monitoring instruments can assess the level of oxygen in the air, alerting to potential suffocation risks. Therefore, all of the above options are correct as monitoring instruments are necessary to determine these specific factors.

The type and location of monitoring equipment should be
- A.
  
  Documented in the Incident Action Plan
- B.
  
  Documented in the Site Safety Plan
- C.
  
  Identified prior to any incident
- D.
  
  Only know to the Incident Commander
Correct Answer
C. Identified prior to any incident

Explanation
The correct answer is "Identified prior to any incident." This means that the type and location of monitoring equipment should be determined and recorded before any incident occurs. This allows for proper planning and preparation, ensuring that the necessary equipment is available and ready to use when needed. By identifying the equipment in advance, it also helps to streamline the response process and ensure that all necessary resources are in place to effectively monitor the situation.

Most command types of monitoring equipment are
- A.
  
  Combustible gas or explosive meters
- B.
  
  Oxygen meters
- C.
  
  Toxicity monitoring devices
- D.
  
  All of the above
Correct Answer
D. All of the above

Explanation
The correct answer is "All of the above". This means that most command types of monitoring equipment include combustible gas or explosive meters, oxygen meters, and toxicity monitoring devices. In other words, all three types of equipment are commonly used for monitoring purposes.
