A _________ effect occurs at the point of contact with a hazardous substance

• A. Global
• B. Systemic
• C. Local
• D. Delayed

Answer: (C)

Local effects occur at the point of contact with a hazardous substance. When a chemical touches the skin, eyes, or mucous membranes, the damage happens right there—causing burns, irritation, or corrosion at that site. In contrast, systemic effects come from the substance being absorbed and circulating through the bloodstream to affect organs elsewhere in the body, not just where contact occurred. Delayed effects are those that don’t appear immediately after exposure, showing up hours or days later. Global isn’t a standard term for this context. So the immediate, site-specific damage described is best called a local effect.
