What is a carcinogen?

A carcinogen is specifically defined as a substance or chemical that is capable of causing cancer in living tissue. This definition is rooted in extensive scientific research that examines the effects of certain agents on human health, particularly in the context of cancer development. Carcinogens can lead to changes in cellular functions or DNA that result in uncontrolled cell growth, which is the hallmark of cancer.

Understanding the nature of carcinogens is vital in the context of workplace safety and health regulations, especially as outlined by OSHA. By identifying and properly labeling carcinogens, employees can be informed about potential risks and take appropriate precautions while handling such substances.

The other choices do not align with the established definition of a carcinogen. Chemicals that cause burns or skin irritation do pose health hazards but are not categorized specifically as carcinogens. Similarly, a harmless chemical cannot be classified as a carcinogen, as it does not have any cancer-related risk associated with it.
