    Product Details

    • Preface/Scope

    Preface


    This is the third edition of CSA Standard Z142 now CAN/CSA-Z142. The first edition was prepared in 1957 and the second in 1976. The need for a new edition of Z142 was prompted by the changing technology related to these machines and by a need felt by the authorities, management, labour, and producers for a document which reflects the latest thinking related to operator and equipment safety.


    A certain amount of repetition of various Clauses in this Standard occurs because of the choices available for powered supply and/or control, eg, pneumatic, hydraulic, mechanical, or electrical. This Standard is structured in such a way as to segregate these different forms of energy with distinct but occasionally repeated Clauses.


    This Standard was prepared by the Technical Committee on Punch Press and Brake Press Operation under the jurisdiction of the Standards Steering Committee on Workplace Safety and Health Practices, and was formally approved by these Committees. It has been approved as a National Standard of Canada by the Standards Council of Canada.


    Scope


    1.1

    The requirements of this Standard apply to all punch press and brake press installations and operations.


    1.2

    This Standard covers the occupational health and safety requirements for all classes of power punch presses and brake presses which are fitted with a ram (plunger or slide) and dies for the purpose of blanking, cutting, trimming, drawing, punching, forming (bending), stamping or assembling metal or other materials.


    1.3

    This Standard sets forth general health and safety requirements for punch presses and brake presses and details safety requirements in danger zones around the point of operation.


    1.4

    Special or additional guarding or other protection may be required where the devices and principles prescribed in this Standard are not directly applicable; including but not limited to machines including bulldozers and hot-forging metal presses. (See CSA Standard CAN/CSA-Z615, Code for Hot Forging Producers, Health and Safety Requirements.)


    1.5

    For the purposes of this Standard a cold material is any material that can be handled with gloved hands. Warm material is material with an upper processing temperature of 760°C (1400°F), handled by means of appropriate tongs or other such devices. Any material whose temperature during processing exceeds 760°C (1400°F) is associated with the metal-forging industry and is outside of the scope of this Standard. (See CSA Standard Z615.)


    1.6

    Any device used or incorporated as a safety device must be designed, manufactured, and supplied for that sole purpose.


    1.7

    The values given in SI(metric) units are the Standard. The values given in parentheses are for information only.
