Free MSHA Mine Rescue Questions and Answers — Questions and Answers
Question 1: If the problem statement states mine has three headings and the team enters from the side, how do you explore? The team map also shows headings.
- Explore each heading sequentially starting from the leftmost heading and moving to the right. (Correct answer)
- Explore each heading randomly without any specific order.
- Explore only the central heading and disregard the others.
- Explore the closest heading first and then move to the next closest.
Correct answer: Explore each heading sequentially starting from the leftmost heading and moving to the right.
Explanation: <br> By exploring each heading sequentially from left to right, the mine rescue team ensures systematic coverage of the mine and minimizes the risk of missing any areas. This approach aligns with standard mine rescue procedures and ensures thorough exploration of the mine.
Question 2: By law, a team is only required to have 6 team members. Can a team with only 6 team members compete at the National Contest?
- Yes, as long as they meet the legal requirement of 6 team members.
- No, they must have at least 7 team members to compete. (Correct answer)
- Yes, they can compete with a waiver from MSHA.
- No, they must have at least 8 team members to compete.
Correct answer: No, they must have at least 7 team members to compete.
Explanation: <br> While the legal requirement set by 30 CFR Part 49 mandates a minimum of 6 team members, the National Rules for Mine Rescue Contests stipulate a minimum of 7 team members to compete. Therefore, a team with only 6 members would not meet the eligibility criteria for the National Contest.
Question 3: A team is advancing in an entry and is stopped by an unsafe roof. There is a gas placard 10 feet out by the unsafe roof. The other entries are blocked, but the team has timbers. If the team timbers through the unsafe roof, does the gas extend through the unsafe roof?
- Yes, the gas extends through the unsafe roof regardless of the presence of a placard.
- Yes, the gas extends through the unsafe roof if there are other entries blocked.
- No, the gas does not extend through the unsafe roof if there was no placard indicating its presence. (Correct answer)
- No, the gas does not extend through the unsafe roof if the team has timbers to secure it.
Correct answer: No, the gas does not extend through the unsafe roof if there was no placard indicating its presence.
Explanation: <br> According to mine safety regulations, the presence of a gas placard indicates the extent of the gas. Since there is no placard at the unsafe roof, the gas is not assumed to extend beyond that point. Therefore, timbers can be used to secure the unsafe roof without the assumption that gas extends through it.
Question 4: Can smoke return in the mine after ventilation is changed? How would that be indicated to the team?
- Yes, smoke can return if ventilation changes are not properly managed, as indicated by increased smoke levels in the mine. (Correct answer)
- No, smoke cannot return once ventilation changes are implemented.
- Yes, smoke can return, but it would be indicated by audible alarms in the mine.
- No, smoke cannot return as long as ventilation changes are made according to the mine's ventilation plan.
Correct answer: Yes, smoke can return if ventilation changes are not properly managed, as indicated by increased smoke levels in the mine.
Explanation: <br> Smoke can potentially return in the mine if ventilation changes are not effectively controlled or if there are unforeseen circumstances. Increased smoke levels would indicate this issue to the mine rescue team, highlighting the importance of constant monitoring and adjustment of ventilation systems to maintain safe working conditions.
Question 5: Can you hold a curtain up to a rib corner that has an unsafe roof running across the imaginary rib line?
- Yes, as long as the curtain is securely fastened to the rib.
- No, holding a curtain up to an unsafe roof is not allowed under any circumstances.
- Yes, but only if the unsafe roof is actively being monitored by the team.
- No, unless the unsafe roof has been properly supported, then holding a curtain is permissible. (Correct answer)
Correct answer: No, unless the unsafe roof has been properly supported, then holding a curtain is permissible.
Explanation: <br> Holding a curtain up to a rib corner with an unsafe roof running across it is generally not allowed due to safety concerns. However, if the unsafe roof has been properly supported and secured by the team, then holding a curtain up to the rib corner can be considered safe. It's essential to ensure the structural integrity of the roof before implementing any safety measures.
Question 6: If timbers are previously set through an area of unsafe roof, does the team have to set its own timbers?
- No, as long as the previously set timbers are still in place and secure.
- No, as long as the mine operator confirms the stability of the previously set timbers.
- Yes, teams must always set their own timbers for safety reasons. (Correct answer)
- Yes, unless authorized by the mine operator to use the existing timbers.
Correct answer: Yes, teams must always set their own timbers for safety reasons.
Explanation: <br> For safety and accountability, mine rescue teams must set their own timbers rather than relying on previously set ones. This ensures that the timbers are properly installed and meet safety standards, reducing the risk of roof collapse or other hazards during rescue operations.
Question 7: If there is an irrespirable atmosphere in an intersection and a barricade 7 feet into the entry ahead, can the team just airlock and go in, or does the team have to clear the intersection first?
- No, the team must always clear the intersection before proceeding.
- Yes, as long as the barricade is secure and there is no irrespirable atmosphere immediately outby it. (Correct answer)
- No, the team must wait for ventilation to clear the intersection before proceeding.
- Yes, if the team feels confident in the barricade's stability, they can airlock and proceed.
Correct answer: Yes, as long as the barricade is secure and there is no irrespirable atmosphere immediately outby it.
Explanation: <br> If there is a barricade 7 feet into the entry ahead and no irrespirable atmosphere immediately outby it, the team can airlock and proceed into the entry. As long as the barricade is secure and there are no immediate hazards, it is safe for the team to advance into the entry.
Question 8: Do patients’ arms have to be strapped down?
- No, it is not necessary to strap down patients' arms as it may impede their ability to remove their mask or CareVent in an emergency. (Correct answer)
- Yes, patients' arms must always be strapped down to prevent movement during transport.
- It depends on the severity of the patient's condition and the recommendation of the medical team.
- No, as long as the patient is conscious and cooperative, their arms do not need to be strapped down.
Correct answer: No, it is not necessary to strap down patients' arms as it may impede their ability to remove their mask or CareVent in an emergency.
Explanation: <br> Strapping down patients' arms may hinder their ability to remove their mask or CareVent quickly in case of an emergency. Therefore, it is generally recommended not to strap down patients' arms during rescue operations to ensure their safety and ability to respond effectively in emergency situations.
Question 9: Should the symbol for FPA be placed on the map in the direction of travel?
- Yes, the symbol for FPA should always be placed in the direction of travel for clarity.
- No, the orientation of the symbol does not matter as long as it is in the correct location. (Correct answer)
- Only if time permits; otherwise, it is not necessary to orient the symbol.
- No, the symbol should be placed randomly on the map without regard to direction.
Correct answer: No, the orientation of the symbol does not matter as long as it is in the correct location.
Explanation: <br> The orientation of the FPA symbol on the map does not affect its functionality. The primary concern is to accurately mark its location for navigation purposes, regardless of the direction of travel.
Question 10: On the fire as a quitter scenario, if a team puts the fire out prior to retreating, will the team be discounted for that?
- Yes, the team will be discounted for putting out the fire before retreating out.
- It depends on the severity of the fire and the judgment of the team captain.
- No, the team will not be discounted as long as they perform all required functions before retreating. (Correct answer)
- No, the team should prioritize extinguishing the fire before retreating out to ensure safety.
Correct answer: No, the team will not be discounted as long as they perform all required functions before retreating.
Explanation: <br> While it's important for the team to retreat promptly in a fire scenario, extinguishing the fire before retreating may not necessarily result in disqualification as long as all required team functions are performed in the designated areas. Safety protocols should be followed, and necessary actions taken to ensure the safety of all team members.
Question 11: If the direction of the fan cannot be changed, do teams still have to put BLOWING OR EXHAUSTING?
- Yes, teams must indicate whether the fan is blowing or exhausting. (Correct answer)
- No, indicating the direction of the fan is optional if it cannot be changed.
- Only if requested by the team captain.
- It depends on the specific mine ventilation plan.
Correct answer: Yes, teams must indicate whether the fan is blowing or exhausting.
Explanation: <br> Even if the direction of the fan cannot be changed, it is still important for teams to accurately indicate whether the fan is blowing air into the mine or exhausting air out of the mine. This information helps in understanding the ventilation flow within the mine and is essential for safety and rescue operations.
