If a hazardous material touches your skin and causes a chemical injury at the site of contact, this is considered a _________ toxic effect.

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

Answer: (D)

Local toxic effects occur where the substance touches the body—the tissue at the contact site bears the injury. When a hazardous material hits the skin and causes a chemical burn, the damage remains confined to that area, not spreading through the bloodstream to distant organs. Systemic toxicity would require absorption with effects elsewhere in the body, which isn’t described here. Delayed refers to when effects appear after some time, and acute describes rapid onset, but neither term denotes the injury’s location. So, the injury is a local toxic effect.
