Why is “PPE” at the bottom of the hierarchy of control?

Correct Answer: D

Rationale: The correct answer is D because Personal Protective Equipment (PPE) is at the bottom of the hierarchy of control as it is the least effective method for controlling hazards. A: PPE may not be effective if not worn properly - True, improper use reduces effectiveness. B: PPE may not be effective if not worn consistently - True, inconsistent use leaves individuals exposed. C: PPE may cause other safety issues - True, improper use can lead to issues like restricted movement or impaired vision. Therefore, D is correct as it encompasses all the reasons why PPE is considered the least effective control measure.

Correct Answer: A

Rationale: The correct answer is A: One third. According to data from the Centers for Disease Control and Prevention (CDC), approximately one-third of injury deaths in the US are classified as "unintentional." This includes deaths resulting from accidents such as car crashes, falls, and poisoning. The other choices are incorrect because: B: Half - While unintentional injuries are a significant cause of death, they do not account for half of all injury deaths. C: Two thirds - This choice overestimates the proportion of unintentional injury deaths. D: Nine tenths - This choice greatly overestimates the proportion of unintentional injury deaths.

Correct Answer: D

Rationale: Proper hand washing falls under the category of maintenance of accepted hygiene practices because it involves following established protocols to prevent the spread of germs and maintain personal cleanliness. It is crucial for reducing the risk of infections and illnesses. Other choices are incorrect as A pertains to equipment safety, B to personal routines, and C to workplace cleanliness, which are not directly related to the specific hygiene practice of hand washing.

Correct Answer: B

Rationale: The correct answer is B: short-term or long-term. This dimension characterizes behavioral consequences based on the time frame over which the consequences are observed. Short-term consequences have immediate effects, while long-term consequences have effects that manifest over an extended period. This dimension is important in understanding the impact of behaviors and helps in predicting future behavior patterns. A: immediate or delayed - This dimension focuses on the timing of consequences rather than the duration, making it different from the dimension in the question. C: limited or extensive - This dimension describes the scope or magnitude of consequences, not the time frame over which they occur. D: compliance or performance - This dimension pertains to different aspects of behavior (following rules vs. achieving outcomes) rather than the duration of consequences.

Correct Answer: C

Rationale: Correct Answer: C Rationale: 1. Goal setting helps to mobilize efforts by providing a clear target to work towards. 2. It increases motivation and focus on achieving the desired outcome. 3. Setting specific goals enhances efficiency and productivity. 4. By defining objectives, individuals can prioritize tasks and allocate resources effectively. Summary: A: While goal setting can contribute to persistence, it is not the primary reason why it is crucial in a multi-tasking world. B: While goal setting does direct attention, the key importance lies in mobilizing efforts to achieve tasks. D: While goal setting may lead to new strategies, its primary role is to drive efforts towards task accomplishment.
