What is an example of an acute health effect from construction activities?

An immediate allergic reaction is a prime example of an acute health effect from construction activities. Acute effects are typically characterized by their quick onset and short duration, often occurring right after exposure to a trigger. In the context of construction, workers may encounter various allergens, such as dust, chemicals, or mold, that provoke immediate physiological responses. These reactions can include symptoms such as hives, swelling, or even more severe respiratory difficulties, showcasing the rapid impact on health due to exposure.

In contrast, long-term respiratory issues, cumulative stress, and chronic fatigue represent chronic health effects that develop over a longer period, often as a result of cumulative exposure. These effects can manifest symptoms that grow progressively worse over time rather than appearing suddenly in response to a specific incident or exposure. Therefore, immediate allergic reactions are distinguished by their acute nature, making them the correct choice in this scenario.
