CSA Z432 Safeguarding of Machinery — 3rd Edition

If you build machin­ery for the Cana­di­an mar­ket, or if you mod­i­fy equip­ment in Cana­di­an work­places, you will be famil­iar with CSA Z432, Safe­guard­ing of Machin­ery. This stan­dard has been around since 1992, with the last major revi­sion pub­lished in 2004. CSA has recon­vened the Tech­ni­cal Com­mit­tee respon­si­ble for this impor­tant stan­dard to revise the doc­u­ment to reflect the cur­rent prac­tices in the machin­ery mar­ket, and to bring in new ideas that are devel­op­ing inter­na­tion­al­ly that affect what Cana­di­an machine builders are doing.

If you have inter­est in this stan­dard and would like to have your thoughts and con­cerns com­mu­ni­cat­ed to the Tech­ni­cal Com­mit­tee, please feel free to con­tact me with your sug­ges­tions. Work starts on 28-Jan-14. Your input is wel­comed!

EC Machinery Working Group meets

From our friends at MachineBuilding.net.

It is now more than a year since the new Machin­ery Direc­tive (2006/42/EC) came into force, but the sit­u­a­tion is still fair­ly flu­id in some respects. The EC Machin­ery Work­ing Group meets reg­u­lar­ly to dis­cuss mat­ters relat­ing to the Direc­tive and cor­re­spond­ing stan­dards; the last meet­ing took place on 21/22 Decem­ber. Accord­ing to the Stake­hold­er Report pub­lished in the UK by BIS (the Depart­ment for Busi­ness, Inno­va­tion & Skills), a num­ber of issues were dis­cussed, which demon­strates that the Machin­ery Direc­tive is not as ‘black and white’ as might be expect­ed.

For exam­ple, EN 12635 (Indus­tri­al, com­mer­cial and garage doors and gates — Instal­la­tion and use) is cur­rent­ly har­monised to the Machin­ery Direc­tive, but the UK has raised a for­mal objec­tion against this stan­dard, as it would appear that there is scope for improve­ment. Oth­er top­ics under dis­cus­sion ranged from vari­able reach trucks, tail lifts and loader cranes, to stave split­ters, dynamome­ters and ‘grey’ imports of machin­ery.

If you would like more infor­ma­tion, copies of the cur­rent and pre­vi­ous Stake­hold­er Reports are avail­able in PDF for­mat from the UK Depart­ment of Busi­ness Infor­ma­tion & Skills (BIS) web site.

Retained fastenings for fixed guards

If you are build­ing machin­ery that will be CE marked or is sub­ject to the EU Machin­ery Direc­tive, you need to read this arti­cle at MachineBuilding.net

This arti­cle reviews some of the retained fas­ten­ings that are avail­able for use on fixed machine guards, as required by the new Machin­ery Direc­tive 2006/42/EC and the guard­ing stan­dard EN 953:1997+A1:2009.

One of the changes in the new Machin­ery Direc­tive is that the Essen­tial Health and Safe­ty Require­ments (, fixed guards), states: “fix­ing sys­tems must remain attached to the guards or machin­ery when the guards are removed.” This new require­ment has also been added to the amend­ed EN 953.

Var­i­ous types of retained fas­ten­ing — such as cap­tive screws and quar­ter-turn fas­ten­ers — are avail­able, but machine builders need to spec­i­fy these with care if they are to find the opti­mum com­bi­na­tion of pur­chase cost, instal­la­tion cost and ease of use. Also bear in mind the require­ment that “fixed guards must be fixed by sys­tems that can be opened or removed only with tools.” What fol­lows is a sum­ma­ry of some of the prod­ucts and sup­pli­ers oper­at­ing in this field.
