Safety is another critical aspect of a high-quality electric blanket. Good electric blankets are equipped with advanced safety features like automatic shut-off mechanisms, which turn off the heating element after a set period to prevent overheating. Overheat protection sensors are also vital, ensuring that the blanket maintains a consistent temperature and avoids any potential fire hazards. Compliance with safety standards and certifications, such as UL or ETL marks, is an indicator that the blanket has undergone rigorous testing and meets recognized safety requirements.
