A university chemistry department purchased a set of digital titrators from a new supplier. Within a month, a technician reported a “spark” when the device was switched on after a routine cleaning with water‑based solvent. The university’s safety officer traced the incident to insufficient IP protection. Because the manufacturer had adhered to IEC 60571’s ingress‑protection requirements, the equipment was re‑certified , the enclosure was upgraded, and the incident was avoided. The lab now references IEC 60571 in all purchase specifications, turning a near‑miss into a lasting safety policy.
