Questions and Answers
1.
It is easier on the back to:
A.
Push a heavy item
B.
Pull a heavy item
C.
Lift a heavy item
D.
Carry a heavy item
Correct Answer
A. Push a heavy item
Explanation Pushing a heavy item is easier on the back because it allows the person to use their leg muscles more effectively. When pushing, the force is directed forward and the person can use their leg muscles to propel the item, reducing strain on the back. On the other hand, pulling a heavy item can put more strain on the back as it requires the person to use their back muscles to maintain balance and control. Lifting a heavy item can also strain the back if proper lifting techniques are not used. Carrying a heavy item can distribute the weight unevenly and put strain on different parts of the back.

The way to sleep that places the least amount of strain on the back is:
A.
On a firm mattress and thin pillow, on your stomach
B.
On a firm mattress and thin pillow, flat on your back or on your side
C.
Flat on your back or on your side
D.
On your stomach
Correct Answer
B. On a firm mattress and thin pillow, flat on your back or on your side
Explanation Sleeping on a firm mattress provides more support for the back, reducing strain and promoting proper alignment. Using a thin pillow helps maintain a neutral spine position. Sleeping flat on the back or on the side also helps distribute body weight evenly and reduces pressure on specific areas, minimizing strain on the back. Sleeping on the stomach can lead to excessive strain on the neck and lower back, making it the least ideal position for minimizing back strain.

When you must stand to do your job:
A.
Tuck the head back and keep shoulders relaxed
B.
Stand with feet about one foot apart
C.
Use a small footstool and change sides frequently
D.
All of the above
Correct Answer
D. All of the above
Explanation The correct answer is "All of the above" because when you must stand to do your job, it is important to tuck the head back and keep shoulders relaxed to maintain good posture. Standing with feet about one foot apart helps to distribute weight evenly and maintain balance. Using a small footstool and changing sides frequently helps to alleviate pressure on the legs and prevent fatigue. Therefore, all of these actions are necessary when standing to do your job.

A back support should:
A.
Be at least 9 inches wide
B.
Have two closures and a slip resistant material on inside surface
C.
Have suspenders and a place to hold tools
D.
Have two closures
Correct Answer
B. Have two closures and a slip resistant material on inside surface
Explanation The back support should have two closures to ensure a secure fit and adjustability. Additionally, it should have a slip-resistant material on the inside surface to prevent it from sliding or shifting during use. These features are important for providing proper support and stability to the back, reducing the risk of injury and promoting good posture. The presence of suspenders and a place to hold tools are not mentioned in the given requirements, so they are not necessary for a back support.

Drinking 6 to 8 glasses of water a day:
A.
May be substituted with juice, soda pop, or coffee
B.
Is not necessary
C.
Reduces the chances of a tearing type injury
D.
Maintains the proper fluid balance in the body
Correct Answer
C. Reduces the chances of a tearing type injury
Explanation Drinking 6 to 8 glasses of water a day helps to reduce the chances of a tearing type injury. This is because staying hydrated helps to keep the body tissues, including muscles, tendons, and ligaments, flexible and less prone to tearing or injury. Water plays a crucial role in maintaining the overall health and function of the body, including proper lubrication of joints and tissues. Therefore, consuming an adequate amount of water on a daily basis can contribute to reducing the risk of tearing injuries.

Most workplace back injuries occur:
A.
Within the first two hours of a shift
B.
Within the last two hours of a shift
C.
Close to break periods
D.
During the first two months of a new job
Correct Answer
A. Within the first two hours of a shift
Explanation Back injuries in the workplace are most likely to occur within the first two hours of a shift. This could be due to a number of factors such as employees not being properly warmed up or stretched before starting work, fatigue from the previous day, or lack of focus and attention at the beginning of the shift. It is important for employers to implement proper training and safety measures to prevent these injuries from happening during this critical time period.

The best lifting technique is:
A.
(1) Pull load close to body, (2) back straight, (3) knees bent, feet apart
B.
(1) Feet apart and knees bent, (2) back straight, (3) keep load close to body
C.
(1) Feet apart and knees bent, (2) lift with legs, (4) keep load close to body and back straight, (5) turn by moving feet, not the body
D.
(1) Back straight, (2) feet apart, (3) knees bent, (4) lift with legs
Correct Answer
C. (1) Feet apart and knees bent, (2) lift with legs, (4) keep load close to body and back straight, (5) turn by moving feet, not the body
Explanation The correct answer emphasizes the importance of maintaining proper body mechanics while lifting. It states that the best lifting technique involves keeping the feet apart and the knees bent, which helps to provide a stable base of support. Lifting with the legs rather than the back helps to distribute the weight evenly and minimize strain on the spine. Keeping the load close to the body and maintaining a straight back further reduces the risk of injury. Additionally, the answer mentions that when turning, it is important to move the feet rather than twisting the body, which helps to avoid strain on the spine.

A proper back support:
A.
Eliminates the need for back safety training
B.
Reminds the wearer to lift with the legs
C.
Provides adequate support for lifting heavy items
D.
Is only as good as the body mechanics of the person wearing it
Correct Answer
D. Is only as good as the body mechanics of the person wearing it
Explanation A proper back support is only effective if the person wearing it has good body mechanics. This means that even with a back support, if the person does not use proper lifting techniques and engage their leg muscles, they can still risk injuring their back. The back support can provide some support and remind the wearer to lift with their legs, but ultimately it is up to the individual to use proper body mechanics while lifting.

If you are in a hurry and a heavy item must be moved to another location:
A.
Use good body mechanics and a back support and carefully lift and move the item
B.
Apply a back support and carefully lift and move the item
C.
Evaluate the lift. If you need another person to help, find someone
D.
Use good body mechanics and carefully lift the item
Correct Answer
C. Evaluate the lift. If you need another person to help, find someone
Explanation The correct answer is "Evaluate the lift. If you need another person to help, find someone." This answer is the most appropriate because it emphasizes the importance of assessing the lift before attempting to move the heavy item. It acknowledges that sometimes a single person may not be able to safely move the item alone and suggests finding someone to assist. This approach prioritizes safety and reduces the risk of injury.
