Basic electrical safety information for the physical therapist is presented, and the most hazardous areas in a physical therapy clinic are identified. Physical therapy modalities are no safer than the power receptacle (wall outlet) into which they are plugged. High frequency physical therapy equipment should never be operated without a three-prong polarized plug and a matching polarized wall receptacle. Three-to-two prong adapters must never be used. Hydrotherapy is an especially dangerous area and should be equipped with ground fault detector receptacles with ground fault interrupters that cut the current when the electrical ground is lost. Ultrasound leakage current measurements on many older ultrasound units may now exceed today's acceptable standards. An external isolation transformer may be required to modify older ultrasonic units before they meet present standards. Physical therapists must never assume that rountine electrical safety inspections are being conducted by hospital maintenance personnel. The physical therapist is responsible for ensuring that all hazardous areas are rountinely checked for electrical safety.
本文介绍了物理治疗师应掌握的基本电气安全信息，并指出了物理治疗诊所中最危险的区域。物理治疗设备并不比其所插入的电源插座（墙上插座）更安全。高频物理治疗设备绝不能在没有三极极化插头和匹配的极化墙上插座的情况下运行。绝不能使用三极转二极适配器。水疗区域特别危险，应配备带有接地故障断路器的接地故障检测插座，当地线丢失时可切断电流。许多老式超声设备的超声泄漏电流测量值现在可能超过当今可接受的标准。在老式超声设备符合当前标准之前，可能需要使用外部隔离变压器进行改装。物理治疗师绝不能认为医院维修人员会定期进行电气安全检查。物理治疗师有责任确保定期检查所有危险区域的电气安全。
