5. PERIODIC CHECKING

5.1 GENERAL

The following sections describe the periodic
checks to be performed on a machine fitted
with a Tapeswitch safety mat system. If the
machine is fitted with additional safety devices
the periodic checks prescribed by the
manufacturer of these devices should be
incorporated into the periodic checking regime
described below.

If the machine fails any of the prescribed
checks the machine must be isolated and must
not be used until the fault has been identified
and rectified.

5.2 COMMISSIONING CHECKS

The commissioning checks should be carried
out by persons who are competent and who
have access to all the information supplied
with the machine and its safety equipment.
The results of the examination should be
recorded and copies of this record should be
kept by the user and the employer of the
person performing the examination.

The person carrying out the examination
should, as a minimum, perform the following
checks:

(a) 

Check that the CKP/

Solo

 is suitable for

use in the application:

(i) Check that the level of safety integrity
provided by the CKP/

Solo

 is suitable for

the level of risk presented by the  machine.

(ii)Check that the environment is suitable
for the use of the CKP/

Solo.

(b)

 Check that the dimensions and position of

the CKP/

Solo

 are correct taking into account

the operating mode. For this purpose it will be
necessary to check the overall system response
time using a device designed for this purpose.

(c) 

Check that adequate measures have been

taken to prevent access to the dangerous parts
of the machine from any direction not covered
by the CKP/

Solo

.

(d) 

Examine the machine controls and

connections to the CKP/

Solo

 to ensure that

the requirements described in this manual and
in the machine manual have been met.

(e) 

Check that the CKP/

Solo 

is fixed in

position and that no trip hazards are present
within the dangerous area.

(f) 

 Except where the device is used solely as

a trip device, check that it is not possible for
a person to stand in the dangerous area
without actuating the CKP/

Solo

.

(g)

 Check that it is not possible for the

dangerous parts of the machine to be set in
motion while the CKP/

Solo

 is actuated.

(h) 

Check that actuation of the CKP/

Solo

during a dangerous phase of operation of the
machine results in the dangerous parts being
arrested, or where appropriate, assuming an
otherwise safe condition, before any part of
a person could reach them.
