A+A 2021 – the leading International Trade Fair for Safety, Security and Health at Work – drew to a successful close. 1,204 exhibitors from 56 nations and more than 25,000 trade visitors travelled to Düsseldorf, Germany to attend the sector’s most relevant trade fair. With these figures A+A – and the concurrently held International Congress for Occupational Safety and Occupational Medicine – again clearly reflected the significantly increased relevance of safety at the workplace.
