Overview
- At least 60 holidaymakers were taken to Marbella’s Costa del Sol Hospital with eye and throat irritation, coughing and vomiting after a pool chemical incident at an unnamed hotel in Benahavis on Tuesday.
- Authorities say a circuit breaker on the pressure pump that injects chlorine and acid appears to have tripped, stopping the dosing systems and allowing toxic gases to form.
- Hotel staff and emergency teams treated other guests on site and sealed the pool, which remains closed while technicians carry out maintenance and safety checks.
- Scientists from a public health and clinical laboratory based at Malaga TechPark are testing pool water and air samples as part of an ongoing regional investigation.
- The episode echoes a major chlorine leak in Majorca in July 2022 and underscores risks when automated chlorine and pH systems fail, which can cause respiratory and eye injuries and trigger regulatory reviews.
