Long-time trucker Andy has been in the lorry game for three decades. He’s a specialist driver, trained to transport extra heavy loads of steel. After a 3am start, he’s picking up from a titan of the Welsh economy - Tata Steel in Port Talbot. Today he’s hauling a particularly hefty load. Work environments don’t come much more hazardous than this, as massive furnaces burn throughout the day and night, breathing sparks, steam and fire. Andy needs to watch his step.
