The event, held annually in Ashton, Northamptonshire, has been organised by the village's conker club since 1965. About 500 entrants from Jamaica, the US, Brazil, the Philippines, Benin and mainland Europe are among those due to compete to be crowned conker champion. The health and safety organisation is also entering a team in the event, held on 12 October.
It says the suggestion they asked children to wear goggles when playing conkers was a myth. IOSH president Ray Hurst said: "We do not, and never have, required children to wear goggles to play conkers. Health and safety doesn't require goggles at conker matches, and it doesn't ban goggles from swimming pools," he added.
The Health and Safety Executive (HSE) website says that it was a headteacher that suggested children should wear goggles to play conkers; other schools then banned the game on health and safety grounds. The HSE said the safety risk from playing conkers was "incredibly low and not worth bothering about".
Mr Hurst added: "I'm looking forward to captaining my team to glory at the championships to show that health and safety people are not spoilsports. You just have to manage the risks, not ban them into oblivion."
