Scaffolding in New Zealand - Best Practice Guideline Policy Rules Definition:  Scaffolding Latin word: Scaffaldus Section Scaffolding  Health and Safety in Employment Regulations 1995 under Clause & Policy & legislation Rules Act.  Any structure or framework, swinging stage, suspended scaffolding, or boatswain's chair, of a temporary nature, used or intended to be used for the support or protection of workers for the purpose of carrying out their work or for the support of materials used in connection with any such work. Scaffolding includes any scaffolding erected as such and not dismantled, whether or not it is being used as scaffolding; and also includes any plank, coupling, fastening, fitting, equipment, item or device used in connection with the construction, erection, dismantling or use of scaffolding References:

PROPRIETARY SCAFFOLDING Proprietary scaffolds have been designed by a chartered engineer as reflected in the manufacturer's specifications for the design and use of the equipment References:13

PROPRIETARY SCAFFOLDING General scaffolding terms applied to proprietary scaffolding References:16

Particular Scaffolds and Scaffolding Structures  Mobile scaffolds  Rakers and outriggers  Scaffolds for roof edge protection (guard railing)  Scaffolding over verandahs, gantries or roofs  Cantilevered scaffolds  Heavy duty gantries  Vessel scaffolds  Hanging scaffolds  Tube and fitting hanging scaffold  Screening or containment sheeting  Mechanical lifting appliances on a scaffold  Mast-climbing work platforms  Barrow ramps  False work or propping  Timber scaffolds References:17

Suspended Scaffolding  A suspended scaffold is a working platform that: Is suspended by ropes from overhead outriggers, needles, parapet hooks or brackets fixed to a building or structure. Is capable of being raised and lowered by hand haulage on fiber ropes, or by hoists that are either manually or mechanically operated using wire ropes References:18

Terminology  Scaffold area The horizontal length of a scaffold in meters times the average height of the scaffold will give the scaffold area in square meters. So: Length (m) x Average Height (m) = Area (m 2 ) The height of the scaffold may be taken from of the height of the top- working platform or alternatively from the top guardrail References:

Health & Safety, Guidelines References: Contractors.html?show_text=1 (Photo) Health and Safety in Employment Act 1992 Scaffolding

Health and Safety in Employment Act 1992 Under the Health and Safety in Employment Act 1992, ‘Serious Harm’ means death or a range of conditions that result in permanent loss of bodily function or temporary severe loss of bodily function References: 21

References:22

2008 Scaffolding fails inspection  59% of the scaffolding failed guard railing safety checks  51% failed on platform checks  A total of 63 Serious Harm incidents involving scaffolding were reported to the Department in the July-June 2006/07 year  45 Serious Harm incidents involving scaffolding had been reported, of which 12 occurred in Auckland References: 23

NZ Scaffolding Scenario Scaffold companies guilty of safety failures A Rotorua company A-Z Rigging and Scaffolding Limited - fined $30,000 and $15.00 in reparation (Sept,2012) Two men have been injured after a scaffolding accident at Charteris Bay NZ (Nov,2012). A Rotorua man was knocked unconscious and spent two days in hospital after he fell from scaffolding when it gave way, the Rotorua District Court has been told (Nov,2012) References: (Photo) 24

References: Strong winds tore a sheeted scaffolding system from this building.

Basic Health and Safety considerations when developing plans, designs or projects include the following: 1. Human Factors 2. Public Interactions 3. Environmental Factors 4. Emergency Provisions

Health & Safety  Scaffolds must be issued with the appropriate Certificate of Compliance and set of guidelines.  Scaffolding exceeding a height of 5m is notifiable to OSH.  Scaffolding must not be erected closer than 4m to any overhead power lines  Scaffolding must be protected from accidental damage by traffic and other causes  Sound and safe means of access should be provided to scaffolding platforms  Scaffolding over verandas, gantries or roofs should be certified as safe by a registered engineer Reference:
