If a chemical's label states it can cause skin irritation and respiratory problems, what type of hazard does this indicate?

A label indicating that a chemical can cause skin irritation and respiratory problems clearly points to a health hazard. Health hazards are defined as substances that can cause significant health issues upon exposure, such as irritation, sensitization, and other longer-term effects on human health. The specific mention of skin irritation relates to dermatological effects, while respiratory problems indicate potential harm to the respiratory system, both of which are direct impacts on health.

Physical hazards, in contrast, involve risks such as fire, explosions, or reactivity, which do not pertain to the health effects indicated in the label. Chemical hazards generally refer to substances that possess properties that can lead to adverse reactions but are more aligned with their physical and chemical characteristics than with direct health implications. Environmental hazards involve risks associated with ecological damage or harm to wildlife and ecosystems, which is also not applicable in this context since the label is directly concerned with human health effects.
