What was the reason there was a pollution “disaster” at Love Canal?

Correct Answer: A

Rationale: The correct answer is A. Hazardous chemicals were disposed of improperly at Love Canal, leading to the pollution disaster. This is supported by historical evidence and investigations that revealed the dumping of toxic chemicals by Hooker Chemical. Choice B is incorrect as it inaccurately states that Hooker Chemical donated their waste dump to the school system. Choice C is incorrect because the development of the land did not ignore the fact that it was a former waste dump; rather, it was developed without awareness of the extent of pollution. Choice D is incorrect as it suggests that the development was done in ignorance, which is not accurate based on the facts of the case.

Correct Answer: D

Rationale: The correct answer is D: Asthma. Asthma is the most common occupational respiratory disease due to exposure to various triggers in the workplace. It is characterized by inflammation and narrowing of the airways, leading to symptoms like wheezing and shortness of breath. Emphysema (A) and Chronic Obstructive Pulmonary Disorder (B) are typically caused by long-term exposure to cigarette smoke, not necessarily occupational factors. Lung cancer (C) is often associated with smoking or exposure to carcinogens, not specifically related to occupation. Asthma is the most common occupational respiratory disease due to exposure to triggers like dust, chemicals, or fumes in the work environment.

Correct Answer: B

Rationale: The correct answer is B because referring to unintentional injuries as "accidents" may imply that they were unavoidable or could not have been prevented. By not using the term "accidents," it emphasizes the importance of preventive measures and encourages a proactive approach to safety. Choice A is incorrect as fault may still exist in unintentional injuries. Choice C is incorrect, as accidents, by definition, are not intentional. Choice D is incorrect as legal precedent does not dictate the terminology used for unintentional injuries.

Correct Answer: B

Rationale: The correct answer is B: The external cause of the injury. The International Classification of Injury categorizes injury data based on the external cause of the injury, such as falls, car accidents, or sports injuries. This classification system helps identify trends, risk factors, and prevention strategies. Choice A is incorrect because the classification is not solely based on whether the injury causes death. Choice C is incorrect as it does not focus on individual risk but rather on the external cause. Choice D is incorrect as job category is not the primary factor in organizing injury data.

Correct Answer: A

Rationale: The correct answer is A: job rotation. Job rotation involves periodically shifting employees between different roles to reduce monotony, prevent overuse injuries, and provide variety. This intervention can help improve occupational health and safety by reducing the risk of musculoskeletal disorders, fatigue, and burnout. Skills training (B) focuses on enhancing employees' abilities but may not directly address safety concerns. Workstation redesign (C) aims to optimize ergonomics but may not impact overall safety. Forming a safety committee (D) is important for promoting a safety culture but is not a direct behavioural intervention for improving occupational health and safety.
