Scaffolds and ladders

                         4.4.4.   Every scaffold should be maintained in  good  and proper condition, and
                     every part should be kept fixed or secured so that no part can be displaced  in
                     consequence of normal use.

                         4.4.5.   No scaffold should be partly dismantled and left so that it is  capable  of
                     being used, unless it continues to be safe for use.



                     4.5.   Lifting appliances on scaffolds


                         4.5.1.   When a lifting appliance is to be used on a scaffold:
                     (a)  the parts of the scaffold should be  carefully inspected  by  a  competent  person  to
                         determine the additional strengthening and other safety measures required;
                     (b)  any movement of the putlogs should be prevented;

                     (c)  if practicable, the uprights should be rigidly connected to a solid part of the building
                         at the place where the lifting appliance is erected.



                     4.6.   Prefabricated scaffolds

                         4.6.1.   In the case of prefabricated scaffold systems the instructions provided by
                     the  manufacturers  or suppliers should be strictly  adhered to. Prefabricated scaffolds
                     should have adequate arrangements for fixing bracing.

                         4.6.2.   Frames of different types should not be intermingled in a single scaffold.



                     4.7.   Use of scaffolds


                         4.7.1.   The  employer  should  provide competent supervision to ensure that all
                     scaffolds are used appropriately and only for the purpose for which they are designed or
                     erected. In transferring heavy loads on or to a scaffold a sudden shock should not be
                     transmitted to the scaffold.


                         4.7.2.   When necessary to prevent danger, loads being hoisted on or to scaffolds
                     should be controlled, e.g. by a hand rope (tag line), so that they cannot strike against the
                     scaffold.

                         4.7.3.   The load on the scaffold should be evenly distributed, as far as practicable,
                     and in any case should be so distributed as to avoid disturbance of the stability of the
                     scaffold.

                         4.7.4.   During the use of a scaffold care should constantly be taken that it is not
                     overloaded or otherwise misused.

                         4.7.5.   Scaffolds should not be used for the storage of material except that
                     required for immediate use.



                                                                                                         17
