- Offshore platforms are hazardous environments where safety systems are mandatory to prevent accidents and protect workers.
- Permit to Work system (A): This ensures that potentially dangerous tasks such as hot work, confined space entry, or electrical work are carried out under controlled conditions with proper authorization.
- Fire and gas alarms (B): Essential safety measures to detect fire hazards, gas leaks, and potential explosions, allowing for immediate evacuation or suppression.
- Lock out-tag out (C): A system that ensures machinery and electrical equipment are isolated during maintenance to prevent accidental startup and injury.
- Financial monitoring system (D) is not a safety system—it deals with economic aspects and has no role in offshore worker protection.
- Hence, the correct safety systems required are (A), (B), and (C).
