Guards, machine-safety

Normally a guard is installed on a moving part of the machine, which acts as a barrier to prevent the entry of any part of the human body in the hazardous area. It is also possible that a safety device is installed that prevents or interrupts the operation if part of the operator s body is in a hazardous area or requires its withdrawal prior to machine operation. The guard or safety device itself must not constitute a hazard, must be safe, low maintenance, easy-to-use, automatically controlled, or fixed on the machines. There are different types of guards and safety devices available according to the design and demands of machines. 

Electric field transducers can also be used. They generate a capacitive field in a hazard area. Any grounded object in the field can he detected. Operators working in that area are grounded and can he sensed by this method to stop the machine before its activation. These are different guards and safety devices that are normally used to avoid mechanical hazards. 

This section addresses additional requirements according to EN 60204-1 (lEC 204-1) for the electrical safety of industrial machines. The requirements presented in the previous sections are applicable to machines and are for the most part contained in EN 60204-1 or other associated standards. I will point out some of the key electri-cai safety items that are often overlooked by the beginning machine safety inspector. EN 60204-1 does not cover all machine safety requirements for guarding, interiocks, control, and so on that are also applicable and listed in the Machinery Directive. 

Machine guards, such as a hard guards or safety light screens, that are designed to protect personnel from hazardous machine motion when close to the machine s point of operation. 

Additional electro-sensitive safety devices and hard guarding measures used for the purpose of preventing a person from reaching over, under, or around the defined area of an installed safety light screen system and into the point of operation of the guarded machine.

Guards and safety devices should be considered when the machinery is being planned, fabricated or purchased. The guard should, as far as possible, appear and function as part of the total machine. 

Think about this. How many companies have you heard of building service (repair) centers as they are designing a new product We have a tendency to anticipate that the product we are building is going to fail. Do we want this in our management system This is the same as someone developing safety policies and procedures or guarding machines after an... 

A prerequisite for securing the safety of automatic machines is that. the machine will function in the intended manner. To prevent or minimize the effects of the potential hazards of the machine adeguate guards and safety devices must be provided. 

By law certain guards and safety devices must be fitted to a variety of work and other equipment. Where such guards and devices are not provided as with, for instance, an imported machine, the importer/supplier could be liable under criminal law, e.g. the Health and Safety at Work Act 1974. 

Once you have access to the Internet, there are several good search engines that are helpful in finding information (Internet sites). These have names such as Google, which is the most conunon. These search engines allow you to find the sites or locations of the information that you are interested in (i.e., machine guarding, fire safety). Internet addresses are constantly changing, so the ability to search is critical. 

Safety guards Devices to protect operators from moving machine parts. 

INDUSTRIAL SAFETY PROVISIONS. In the design of the APE and associated operational shield, conventional machine design practices are used to protect operators from hazards associated with moving parts. Proper techniques for guarding of hazardous machine areas are used, including the use of interlocks In the control system to prevent movements until certain conditions are satisfied, or to stop movements In emergency situations... 

Standard safety precautions for the operation of the machine must be adhered to at all times, and the guarding of the machine must be operational and used. Personal protective equipment must also be used. Eye protection is particularly important. The part must be correctly mounted on the machine with just sufficient force to prevent it from moving and coming loose during the operation. The tool and its holder must not interfere with the part when internal work is being done. This may cause the part to come loose under speed.
