The Royal Society for the Prevention of Accidents has promoted Errol Taylor to chief executive.
Taylor, who has been the charity’s deputy chief executive since 2006, takes over from Tom Mullarkey, who stood down in April after almost 11 years in the role.
Taylor, who has been acting up as chief executive, joined the charity in 2004 as head of its commercial activities.
The charity, which had an income of £7.6m in the year to the end of March 2016 and employs about 120 people, is marking its centenary this year.
Mike Parker, chairman of Rospa, said: "The board believes that Errol’s passion for accident prevention, energy, skills and experience will ensure RoSPA’s continued success for the foreseeable future.
"His enthusiasm for working in partnership with Rospa’s many like-minded stakeholder organisations should, in time, lead to a significant reduction in the burden of accidental injury."
Taylor said: "I am proud to lead a fantastic team of dedicated colleagues and look forward to continuing to develop RoSPA’s valued relationships with other individuals and organisations across the health and safety community."
A spokesman was unable to confirm how much Taylor would be paid for his new role.
According to the charity’s most recently available accounts, for the year to the end of March 2016, its highest-paid staff member, who is not named, was paid between £160,001 and £170,000.
