Helmets in cricket were developed in the 20th century. History There are recorded instances of cricketers using scarves and padded caps to protect themselves throughout cricket history. Patsy Hendren was one of the first to use a self-designed protective hat in the 1930s. Helmets were not in common use until the 1970s. The first helmets were seen in World Series Cricket, with Dennis Amiss being the first player to consistently wear a helmet which was a customised motorcycle helmet. Mike Brearley was another player who wore his own design. Tony Greig was of the opinion that they would make cricket more dangerous by encouraging bowlers to bounce the batsmen. Graham Yallop of Australia was the first to wear a protective helmet to a test match on 17 March 1978, when playing against West Indies at Bridgetown. Later Dennis Amiss of England popularised it in Test cricket. Helmets began to be widely worn thereafter. The last batsmen at the highest (Test match) level to never wear a helmet throughout his career was Viv Richards, who retired from the international game in 1991. Modern day cricket helmets Modern day cricket helmets are made in compliance with the recent safety standards of the International Cricket Council (ICC) and have to conform to the British Standard BS7928:2013. Materials used for making cricket helmets are impact resistance materials like ABS Plastic, Fibreglass, carbon fibre, titanium, steel and high density foam etc. Main parts of a cricket helmets are grill (made with steel, titanium or carbon fibre), chin strap, inner foam material, outer impact resistant shell etc. Legislation As of 2017, the ICC has refused to pass laws requiring the wearing of helmets, rather leaving the decision to each test nation to decide for themselves. However, although it is not obligatory for a batsman to wear a helmet, should he chose to do so, the helmet must comply with specific safety requirements, a rule all the test playing nations have agreed to. In first class cricket, as of 2016, England requires all batsmen, wicketkeepers and fielders closer than 8 yards from the wicket to wear helmets. This is mandatory even when facing medium-pace and spin bowling. New Zealand and India do not require batsmen to wear helmets. Australia requires helmets to be worn by batsmen if facing fast or medium-paced bowling; wicketkeepers if keeping up to the stumps; and all fielders in positions within 7 metres
