Which of the following is a common workplace hazard related to chemical exposure?

Inhalation of toxic substances represents a significant workplace hazard related to chemical exposure. When employees are exposed to chemicals, they can breathe in vapors, gases, or dust that can harm their respiratory systems or overall health. This type of exposure can lead to various health issues, ranging from short-term effects like irritation of the eyes, skin, or respiratory tract to long-term effects such as chronic lung diseases or cancers. Proper ventilation, personal protective equipment, and training on the handling of hazardous materials are crucial to mitigate this risk in the workplace.

The other options, while they present real hazards in a workplace setting, do not specifically relate to chemical exposure in the same way. Electrical shocks pertain to hazards associated with electricity, fire hazards relate to potential ignitable materials, and slip and trip risks involve physical conditions that can lead to falls, none of which directly involve the inhalation or handling of chemicals.
