This study aims to investigate laws and standards(including technical guidelines) related to safety criteria for 22 kitchen machines frequently used in commercial kitchens. The study was based on literature survey, interviews with charge persons in kitchen machines manufacturing companies, cafeteria providing group meals and relevant association, and web surfing. The results showed that there are two types of safety criteria such as legally forced ones by laws and optional ones by national industrial standards or technical guidelines. High pressure safety control act, safety control and business of liquefied petroleum gas act and city gas business act prescribed gas use apparatus safety criteria, rational energy utilization act did those of pressure vessel such large rotary caldron, industrial health and safety act did those of food processing machinery, and electrical appliances safety control act did those of electrical kitchen appliances. Compulsory or optional standards or guidelines related to safety criteria for kitchen machines were presented by 22 kitchen machines. Safety devices shown in the laws, standards and guidelines were also summarized by kitchen machines and their risk factors.

The purpose of this study is to investigate EU, UK and USA’s laws and standards related to safety criteria for commercial kitchen machines. The study was based on literature survey and web surfing. The results revealed that EU has relevant directives by kitchen machines and harmonized standards according to the directives. The directives and harmonized standards are translated into the laws and standards of EU member countries, respectively. The kitchen facility relevant legal systems of UK and USA do not prescribe the safety devices or measures, but only the basic health and safety requirements. The requirements were forcefully implemented through the certificate systems such as CE(Confommite European), UL(Underwriters Laboratories), etc. Only products with CE, UL or NRTL(ationally Recognized Testing Laboratory) certificate marking can be placed on the market of EU and USA, or put into service. For achieving the certificates, all requirements regulated in the relevant standards should be met. The standards of UK and USA were presented by kitchen machines or by standards themselves, respectively. Safety devices required by the standards were also summarized by kitchen machines and their risk factors.
