What term is used for chemicals that may cause acute or chronic health effects after exposure?

The term "health hazard" refers to substances that pose a risk to health, either immediately (acute) or over a longer period (chronic) following exposure. This includes a wide variety of chemicals that can lead to health issues, such as respiratory problems, skin irritation, or long-term conditions like cancer, depending on the level and duration of exposure. Understanding health hazards is crucial in workplaces such as those involving lineman activities, where workers may encounter various substances that could jeopardize their health.

In this context, "toxic substance" is closely related but more specific; it refers particularly to chemicals that are poisonous. "Environmental risk" generally pertains to substances that could harm ecosystems rather than directly affect health. "Non-hazardous material" indicates materials that do not pose health or safety risks, so they are not relevant in this situation.
