Sudden cardiac arrest can happen without warning and requires immediate action. Rapid access to CPR and an Automated External Defibrillator can significantly improve the chances of survival, which is why AED provision is now a key consideration within BS8599-1:2026 workplace first aid guidance.
Businesses with an estimated five or more people on site during operating hours should review AED provision as part of their first aid needs assessment. Employers should make a realistic estimate of maximum and regular occupancy, including employees, visitors, contractors and customers where relevant.
An AED should be clearly displayed in a cabinet or wall-mounted position and accessible within two minutes from any location on the premises. Larger workplaces, multiple-building sites or sites with public access may need more than one AED to meet this response expectation.
