Final answer:
Members of the public can be exposed to chemical hazards through inhalation, skin contact, and ingestion, especially in areas with poor ventilation or contaminated environments. Protective measures and employer responsibilities are crucial in preventing exposure.
Step-by-step explanation:
Members of the public can be exposed to hazards in a chemical plant via several routes. The three main routes of exposure to chemicals are inhalation, skin contact, and ingestion. In a chemical plant, exposure can occur through the inhalation of pesticide fumes or other harmful vapors, particularly in settings with inadequate ventilation such as greenhouses or tractor cabs. Skin contact, especially on exposed areas such as hands and face, can lead to direct absorption of harmful substances. Additionally, contaminants can enter water sources or soil, leading to ingestion of these toxins through contaminated food or water. Preventative measures include using less toxic chemicals, ensuring proper ventilation, and providing education and personal protective equipment (PPE) for workers and the community. Employers are responsible for implementing safety procedures to minimize risks, in compliance with regulations like those from the Occupational Safety and Health Administration (OSHA).
