NIST GCR 01-814
A Guide to the EU Machinery Directive
- The manufacturer must envisage not only the normal use of the machinery, but also uses that could reasonably be expected.
- The machinery must be designed to prevent abnormal use if such use would engender a risk.
- Discomfort, fatigue and psychological stresses upon the operator must be reduced to the minimum possible. (See Machinery Harmonized Standards* for ergonomics standards listed at the end of this report)
- The manufacturer must take into account the possible use of personal protective equipment and the constraints they will put upon the operator. Note: The use of personal protective equipment worn to prevent risks inherent in the machinery must be part of the information supplied by the manufacturer in the instructions.
- Machinery must be supplied with any special equipment or accessories that will enable it to be maintained and used without risk.
Note: The manufacturer should also be aware that there is a European law (Directive 89/655/EEC) and there are local (national) regulations that place some of the burden of safety on professional machine users. Employers, for example, must provide certain training and worker information and take some responsibility for providing instructions on the use of machinery. Likewise, the manufacturer is not responsible for modifications to a new machine by the user. The Declaration of Conformity (See NIST SP 951 A Guide to EU Standards and Conformity Assessment, Page 26) only covers the machine in its original state.
- Material that is used to construct the machinery or products used and created during its use must not put people at risk or endanger their safety or health. Where fluids are used, for example, machines must be designed for use without risks during filling, use, recovery, or draining.
- The manufacturer must supply suitable lighting where its lack is likely to cause a risk, even when there is normal ambient lighting. There should be no shadows, dazzles, and no dangerous stroboscopic effects due to the lighting provided by the manufacturer. Internal parts requiring frequent inspection and adjustment and maintenance areas, must also be provided with appropriate lighting.
