What are the recognized ways that hazardous materials can harm people?

Hazardous materials can harm individuals primarily through acute and chronic effects along with different routes of entry. Acute effects refer to immediate adverse health effects that appear shortly after exposure to hazardous materials, such as symptoms from chemicals causing irritation or poisoning. Chronic effects develop over time, often as a result of long-term exposure, which can lead to conditions such as cancer or respiratory issues.

Additionally, the routes of entry are critical in understanding how hazardous materials affect human health. These routes typically include inhalation, ingestion, skin absorption, and injection, each presenting different risks and responses depending on the nature of the hazardous substance involved. This comprehensive approach to examining both the type of effects and the pathways of exposure is essential for effectively assessing the risks posed by hazardous materials.

In contrast, other options do not capture the full scope of how hazardous materials can harm individuals. Changes in temperature and humidity do not directly pertain to the effects of hazardous materials on health. Increased pressure and treatment resistance are not features typically associated with the direct harmful effects of hazardous substances. Asphyxiation and numbness of the extremities may occur as a result of specific types of exposure but do not encompass the broader range of acute and chronic health effects. Thus, understanding both the type of health effects
