What is the difference between passive and active protection?

• A. Passive uses barriers and signs; active uses personnel actively guarding and signaling
• B. Passive is more dangerous
• C. Active requires no protection
• D. Both identical

Answer: (A)

Passive protection consists of safeguards that operate without needing people to act at the moment danger could arise. These are physical or design features like barriers, fences, safety signs, warning lights, and other features that prevent access or alert people automatically. Active protection relies on human action or automated monitoring that requires ongoing intervention to prevent an incident. This includes personnel patrolling or directing traffic, flaggers or signalers guiding trains or road users, and alarms or remote signaling systems that respond to a hazard. So, passive uses barriers and signs to reduce risk automatically, while active protection involves people or systems actively directing, signaling, or intervening to prevent danger. The other options don’t fit: passive isn’t inherently more dangerous; active protection doesn’t imply it’s unnecessary; and the protections aren’t identical.
