B.2. Identify risks by area: risks identified in each area are as follows: Refining area
Continuous casting machine area
- Heat release - Falling of the load - Gas leakage - Sparks during temperature rise
- Oxygen leakage - Manual handling - Burns - Inhalation - Slip
- Gas leakage - Oxygen leakage - Fall of the load - Release of heat - Sparks during the temperature rise
- Mechanical handling - Falling on the floor - Burns - Manual handling
Fluid area
Refractory area
- Slip (welder lance) - Fire/ explosion
-Electrification - Flame back
- Falling to the ground - Release of heat
- Projection of sparks - Contact with a hot element - Handling with a crane - Exposure to noise - Exposure to vibration
- Projection of molten metal - The falling object (tundish preparer)
Common area
Maintenance area
Degraded mode
- Falling objects (dispatcher)
- Slip (cst agent) - Fire/ explosion (cst agent) - Electrification (cst agent) - Fall from height (cst agent)
- Fall of liquid steel and dirt at zero level - Overflow at the converter level, water leakage at the skirt level - Explosion
- Contact with metal (operations manager) - Loss of control (driver)
