Nathan said: “Just before he collapsed, Raj was about to drive a truck, and the outcome could have been very different had he been behind the wheel when he was taken ill. Or it could have happened when he was on the scaffolding and would have fallen from a height.
“I ran out to find Raj lying on the floor in our yard and, at first, it looked like he was having a seizure. At that point he was still conscious, so I put him in the recovery position.
“All the lads were standing around in disbelief. Then Raj made a kind of snoring sound before I realised he wasn’t breathing. I asked someone to call an ambulance, and the call was put on loudspeaker. The operator told me to start CPR, which I did.
“Raj’s son Harvey, who also works for us, came into the yard at the time and I told people to take him inside.
“I was giving chest compressions for around six or seven minutes before the ambulance arrived. The paramedics told me to carry on while they set up their equipment, including a mechanical CPR machine.
“They then used a defibrillator and after four or five shocks they got Raj’s heart going again. The paramedics are the real heroes.
“They were working on him for about 40 minutes before he was taken to Queen Elizabeth Hospital in Birmingham.”
Raj, 52, was in hospital for over a week and had a stent fitted. He had also suffered a stroke and a heart attack and was in an induced coma for two days. He is still off work and recovering at his Willenhall home.
Nathan, who updated his training with a two-day refresher course at St John Ambulance’s Dudley base last February, added: “Two or three days after coming out of hospital, Raj phoned me to thank me for what I had done.
“The incident really affected everyone at the yard. We had to send some of the lads home, and it took a couple of days for everything to sink in. We have all known each other for years, we are all friends, and it did shake them up.
“I managed to remain calm, and from somewhere, at the back of my brain, the training came flooding back. I can’t express how important these first aid courses are. I never thought this moment would come but when I needed to act, I didn’t panic and the training kicked in.”
