IEC 60745: Hand-held Motor-operated Electric Tools - Safety Requirements




Hand-held motor-operated electric tools are widely used in various industries and applications for tasks such as cutting, drilling, grinding, and fastening. The safety of these tools is of utmost importance to protect operators from hazards such as electrical shock, mechanical injuries, and exposure to harmful substances. The International Electrotechnical Commission (IEC) standard IEC 60745 sets forth safety requirements for hand-held motor-operated electric tools to ensure their safe and reliable operation. This article explores the key safety requirements specified in IEC 60745 and their significance in promoting operator safety and preventing accidents.


Key Safety Requirements in IEC 60745 for Hand-held Motor-operated Electric Tools


IEC 60745 establishes a range of safety requirements for hand-held motor-operated electric tools to address potential hazards and risks associated with their use. Some of the key safety requirements specified in the standard include:


1. Electrical Safety: The standard includes requirements for electrical insulation, grounding, protection against electric shock, and compatibility with electrical supply systems to ensure the safe use of electric tools.


2. Mechanical Safety: IEC 60745 addresses mechanical hazards such as blade or disc breakage, excessive vibrations, and ergonomic design to prevent injuries due to tool failure or improper handling.


3. Thermal Safety: The standard specifies requirements for heat dissipation, temperature limits, and thermal protection mechanisms to prevent overheating and fire hazards during tool operation.


4. Ergonomics and Human Factors: IEC 60745 includes provisions for handle design, vibration levels, noise emissions, and user-friendly controls to minimize operator fatigue, discomfort, and musculoskeletal injuries.


5. Protection Against Harmful Substances: The standard covers requirements for protection against exposure to harmful substances, including dust, fumes, and chemicals, to safeguard operator health during tool use.


6. Safety Labels and Instructions: IEC 60745 mandates the inclusion of safety labels, warnings, and user instructions on electric tools to provide operators with vital information on safe handling, maintenance, and potential hazards.


Applications of Hand-held Motor-operated Electric Tools


Hand-held motor-operated electric tools are used in a wide range of industries and professions, including:


1. Construction: Electric tools such as drills, saws, grinders, and sanders are commonly used in construction sites for various tasks such as drilling, cutting, and finishing.


2. Manufacturing: Electric tools play a key role in manufacturing processes for tasks like assembly, machining, welding, and material handling.


3. Automotive: Electric tools are used in automotive repair and maintenance for tasks such as fastening, grinding, polishing, and painting.


4. Woodworking: Electric tools such as routers, planers, saws, and sanders are essential in woodworking shops for shaping, cutting, and finishing wood.




IEC 60745 sets safety requirements for hand-held motor-operated electric tools, emphasizing the importance of operator safety, tool reliability, and accident prevention. Compliance with the safety provisions outlined in the standard is essential for manufacturers, distributors, employers, and users of electric tools to ensure safe working conditions, reduce the risk of injuries, and promote a culture of safety in workplaces.
