HARVEST can be a time of huge pressure for farmers and contractors - and it is at the busy times in the farming year when accidents are most likely to happen. Dr Peter Dodman of the Health and Safety Executive offers advice on avoiding accidents over the harvest period.

Maintaining equipment properly before starting work can not only prevent accidents but also reduce the time jobs take, he says. Brakes on vehicles need to be efficient, particularly on tractors and trailers.

Vehicles should have suitable reversing mirrors which are kept clean, although avoid reversing at all if you possibly can. Where reversing is necessary, do not allow anyone on foot in the vicinity, other than someone who is trained to help.

When emerging from a field on to a public road, maximise your visibility and take particular care.

Never carry passengers unless the vehicle is designed to take them.

Keep well clear of overhead power lines where there could be a risk of contact with them, particularly when using combines, tipping trailers, telehandlers or other high pieces of equipment.

Make sure grain pits are adequately covered and do not attempt to walk on grain or oil seed rape inside a silo. Grain dust can cause lung disease so, where possible, provide good extraction or wear a suitable dust mask.

Bales should be stacked safely and work at heights avoided unless a safe means of access is used.

If equipment does break down or need maintenance, always stop it before attempting repairs, adjustments or greasing it. Nobody wants a repeat of the recent horrific accident in which a local man lost a hand while working on a baler which was running at the time.

Finally, says Dr Dodman, always take the time to think: "What might happen if ...?" - and take any necessary precautions. Do not knowingly take risks or shortcuts - it is never worth it in the long run.

Much of this advice may seem obvious, he says, but too many farmers are still having accidents. Thinking ahead and taking steps to ensure the harvest is carried out as safely as possible is time well spent.
