What is a key reason industrial robots are used in hazardous environments?

• A. They substitute for humans in hazardous work environments.
• B. They are used to decorate warehouses.
• C. They require more hazard exposure.
• D. They operate only with human supervision.

Answer: (A)

Industrial robots are used in hazardous environments mainly to substitute for humans in dangerous tasks, so people aren’t exposed to risks like heavy lifting, extreme heat, toxic substances, or repetitive, high‑risk motions. Robots can endure harsh conditions, work continuously, and deliver consistent precision while safety systems guard workers around them. The other options don’t capture this purpose: decorating warehouses isn’t their function, increasing hazard exposure defeats safety goals, and operating only with human supervision ignores the autonomy and safety measures that enable robots to handle dangerous work.
