Alan's first-aid skills saves the life of colleague.
Mr Bennett, aged 33, and colleagues at Christian Salvesen's depot at Rowley Regis, West Midlands, have been commended by the county's ambulance service for giving Dave Brown 'the best possible chances of survival'.
Mr Brown, aged 56, is now making a good recovery at home.
The events showed the importance of encouraging first-aid training within a business organisation.
The emergency began when Mr Brown, who is also a warehouse supervisor and first-aider, collapsed at work.
Mr Bennett ran to him and began checking his pulse and breathing while operations manager Ed Ross telephoned for an ambulance.
'When I got to Dave, he was still breathing and his pulse was very rapid,' said Mr. Bennett.
'Then his condition deteriorated and he 'died' on me.'
With the help of Christian Salvesen driver Lee Ball, Mr Bennett turned Mr Brown on to his back and began mouth-to-mouth resuscitation while Mr Ross called the ambulance service again to relay details of Mr Brown's condition.
Other colleagues began removing barriers to make it easier for paramedics to reach their patient.
'When the paramedics arrived, they told me I was doing a good job and to keep giving Dave mouth-to-mouth while they set up a defibrillator to give his heart an electric shock,' said Mr Bennett.
Mr Brown, whose heart stopped five times during the emergency, was taken to Russells Hall Hospital, at Dudley, where he spent ten days before being discharged.
'One of the first things Dave did after he left hospital was to visit the depot to thank me and the lads,' said Mr Bennett.
'It was the first time I had dealt with anything on this scale, and I am just relieved I remembered my training and did not panic.'
Mr Bennett is one of seven first-aiders providing day and night cover at the Rowley Regis depot which handles a wide range of products for leading manufacturers, including automotive parts and chemicals.
Christian Salvesen encouraged him to become a first-aider four years ago and sent him on a St John Ambulance training course.
'I would recommend it to others,' Mr Bennett added.
'Learning basic first-aid skills is not difficult and you could save someone's life at home or in the street, as well as at work.'
Dave Betts, managing director UK of Salvesen's industrial division, said: 'The safety and welfare of our people is paramount.
'Alan and all those involved clearly saved the life of one of their colleagues. I cannot praise them enough.'
