Designing a safeguarding solution for work cells requires striking a balance between floor space, ease of installation控制工程网版权所有, productivity, safety, and initial and ongoing maintenance costs. When determining the proper method of machine safeguarding, however, it is important that other occasional operations like setup, cleaning控制工程网版权所有, maintenance and adjustments are also taken into account.
        European laws and directives require the equipment manufacturer to provide the necessary safety equipment to be delivered with the machine. However, in the U.S., the ultimate responsibility for safeguarding falls on the end user company to provide its employees an environment free of hazards that are likely to cause harm or injury. When employees do not have to worry about getting hurt on the job, they ultimately are more productive.
        Because there are many ways to safeguard a machine, a risk assessment should be performed first. This will identify the potential for injury at a machine, or the process of interacting with the equipment. Performing a risk assessment is particularly important控制工程网版权所有, considering that complete isolation between a hazard and an operator is often not practicalwww.cechina.cn, especially in instances where increased productivity is used to save money and/or increase revenue.
        The older and more common techniques of using hard guarding require special procedures when entering a hazardous area. Although hard guarding provides a good visual indication of the location of the hazardCONTROL ENGINEERING China版权所有, many processes require frequent interaction at or near the hazardous motion and, therefore, do not make hard guarding practical.
