DIRECTIVE 2006/42/EC ANNEX I_EHSR


1.3. PROTECTION AGAINST MECHANICAL HAZARDS
1.3.1. Risk of loss of stability
Machinery and its components and fittings must be stable enough to avoid overturning, falling or uncontrolled
movements during transportation, assembly, dismantling and any other action involving the
machinery.
If the shape of the machinery itself or its intended installation does not offer sufficient stability, appropriate
means of anchorage must be incorporated and indicated in the instructions.
1.3.2. Risk of break-up during operation
The various parts of machinery and their linkages must be able to withstand the stresses to which they are
subject when used.
The durability of the materials used must be adequate for the nature of the working environment foreseen by
the manufacturer or his authorised representative, in particular as regards the phenomena of fatigue, ageing,
corrosion and abrasion.
The instructions must indicate the type and frequency of inspections and maintenance required for safety
reasons. They must, where appropriate, indicate the parts subject to wear and the criteria for replacement.
Where a risk of rupture or disintegration remains despite the measures taken, the parts concerned must be
mounted, positioned and/or guarded in such a way that any fragments will be contained, preventing hazardous
situations.
Both rigid and flexible pipes carrying fluids, particularly those under high pressure, must be able to withstand
the foreseen internal and external stresses and must be firmly attached and/or protected to ensure that no risk
is posed by a rupture.
Where the material to be processed is fed to the tool automatically, the following conditions must be fulfilled
to avoid risks to persons:
— when the workpiece comes into contact with the tool, the latter must have attained its normal working
condition,
— when the tool starts and/or stops (intentionally or accidentally), the feed movement and the tool movement
must be coordinated.
1.3.3. Risks due to falling or ejected objects
Precautions must be taken to prevent risks from falling or ejected objects.
1.3.4. Risks due to surfaces, edges or angles
Insofar as their purpose allows, accessible parts of the machinery must have no sharp edges, no sharp angles
and no rough surfaces likely to cause injury.
1.3.5. Risks related to combined machinery
Where the machinery is intended to carry out several different operations with manual removal of the piece
between each operation (combined machinery), it must be designed and constructed in such a way as to
enable each element to be used separately without the other elements constituting a risk for exposed persons.
For this purpose, it must be possible to start and stop separately any elements that are not protected.
1.3.6. Risks related to variations in operating conditions
Where the machinery performs operations under different conditions of use, it must be designed and
constructed in such a way that selection and adjustment of these conditions can be carried out safely and reliably.

1.3.7. Risks related to moving parts
The moving parts of machinery must be designed and constructed in such a way as to prevent risks of
contact which could lead to accidents or must, where risks persist, be fitted with guards or protective devices.
All necessary steps must be taken to prevent accidental blockage of moving parts involved in the work. In
cases where, despite the precautions taken, a blockage is likely to occur, the necessary specific protective
devices and tools must, when appropriate, be provided to enable the equipment to be safely unblocked.
The instructions and, where possible, a sign on the machinery shall identify these specific protective devices
and how they are to be used.
1.3.8. Choice of protection against risks arising from moving parts
Guards or protective devices designed to protect against risks arising from moving parts must be selected on
the basis of the type of risk. The following guidelines must be used to help to make the choice.
1.3.8.1. Moving transmission parts
Guards designed to protect persons against the hazards generated by moving transmission parts must be:
— either fixed guards as referred to in section 1.4.2.1, or
— interlocking movable guards as referred to in section 1.4.2.2.
Interlocking movable guards should be used where frequent access is envisaged.
1.3.8.2. Moving parts involved in the process
Guards or protective devices designed to protect persons against the hazards generated by moving parts
involved in the process must be:
— either fixed guards as referred to in section 1.4.2.1, or
— interlocking movable guards as referred to in section 1.4.2.2, or
— protective devices as referred to in section 1.4.3, or
— a combination of the above.
However, when certain moving parts directly involved in the process cannot be made completely inaccessible
during operation owing to operations requiring operator intervention, such parts must be fitted with:
— fixed guards or interlocking movable guards preventing access to those sections of the parts that are not
used in the work, and
— adjustable guards as referred to in section 1.4.2.3 restricting access to those sections of the moving parts
where access is necessary.
1.3.9. Risks of uncontrolled movements
When a part of the machinery has been stopped, any drift away from the stopping position, for whatever
reason other than action on the control devices, must be prevented or must be such that it does not present a hazard.
