Machine guard location

Companies can define the scope and focus of the audit in terms of organizational, geographical, functional, and compliance contexts (National Safety Council 1997,102). These boundaries include departments within the organization, activities, and safety areas such as fire protection, industrial hygiene, and machine guarding. The audit instrument should provide the auditor with a thorough understanding of the scope of the audit process. This would ensure that areas that need to be addressed are not bypassed. The audit protocol is the auditor s plan to accomplish the objectives of the audit (National Safety Council 1997,107). The protocol provides the auditor with instructions on the locations to audit and the areas that should be addressed. Descriptions of the situations that indicate compliance and non-compliance with the audit protocol should be included with the audit items. 

Equipment must be designed so that convenient accessibility is provided for maintenance facilities and tools must be designed such that maintenance related service controls, instruments, lube points, shut off valves etc. are visible and fully accessible from the shop floor in a convenient location outside of machine guarding. 

The system boundary could be drawn at various levels — e.g. in the guarding example it could be drawn at the level of the department in which the machine is located, the works, the company, or the country (in the last case there might be inputs across the boundary (frontier) of materials, designs or EEC regulations which would still make it an open system). For a full systems analysis and model it is usually necessary to produce a hierarchy of diagrams showing the total system, main sub-systems and sub-sub-systems etc. 

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. 

The top has a 5 mm wide slot along its centre, through which the heat passes. Fig. 14.5. When the material is pliable, it can be located in a former and bent to the required angle, e.g. in making a splash guard for a lathe, Fig. 14.6. The material can be removed from the former when the temperature drops to about 60 °C. Formers can be simply made from any convenient material such as wood. For volume production large-scale industrial machines are available which can have multiple bending areas and advanced heat control. 

Safeguards include guards, devices, distance, or location. Safeguards for machines fall into two major groups mechanical power transmission safeguards, and point-of-operation safeguards. 

These are devices which require the operator to have both hands In a safe place (the location of the controis) before the machine can be operated. They are an option on machinery that is otherwise very difficult to guard but they have the drawback that they only protect the operator s hands. It is therefore essential that the design does not allow any other part of the operator s body to enter the danger zone during operation. More significantly, they give no protection to anyone other than the operator. 

Before mounting the grinding wheel, the speed of the machine shall be checked to ensure that it does not exceed the maximum operating speed marked on the grinding wheel. Safety guards shall be adjusted to allow maximum protection for the grinding wheel operator. Grinding wheels shall be stored in a clean and dry location.
