Codes of Practice: provide practical

guidelines to complywith legislation

are used to support enforcement and prosecution

Electrical SafetyElectrical Safety avoid exposed live electrical wiring

earth leakage protection fitted to power sources

electrical leads stored away from traffic, water and ground moisture

regular inspection and maintenance of equipment

avoid long lead lengths, piggy backs and double adaptors

use spotter, NO GO Zone near power lines risk

Electrical SafetyElectrical SafetyInspection and Tagging tools/leads inspected and tagged every 3 months tools, plant, leads inspected prior to use electrician’s current colour-coded tag displayed on

tools/leadsExtension Leads use heavy duty leads maximum length limited by amp rating must not run from one floor to another must be suspended over head from insulated stands

or hooks

OHS Training 2003 99OHS Training 2003Induction

Electrical SafetyElectrical SafetyEarth Leakage Protection power supply to all sites (new constructions and

refurbishments) must have earth leakage or residual current device protection

plugging into any General Purpose Outlet connection should be through self-contained earth leakage box

Demolition/Major RefurbishmentAll work must be subject of site specific JSA covering: isolation of pre-existing power sources establishing an earth leakage protected switchboard inspection for rogue cables, live wiring

Hazard IdentificationHazard Identification

Classification of HazardsHazards can be classified in two ways:1. Class 1, Class 2, Class 3

• Class 1: hazards that have potential to cause death or permanent disability

• Class 2: hazards that have potential to cause lost time injury

• Class 3: hazards that have potential to result in first aid treatment

2. High, Medium, Low (same as Class 1, 2, 3)

OHS Training 2003 1515OHS Training 2003Induction

Risk AssessmentRisk AssessmentAsk these questions about the risk: how significant is risk? can risk be eliminated? what control measures can be implemented to

reduce if not eliminate risk? can expending resources to remove or reduce

risk be justified?

OHS Training 2003 1616OHS Training 2003Induction

Risk AssessmentRisk Assessment

Who should be responsible for risk assessments?

site managers site teams safety

representatives OH&S committees subcontractors

OHS Training 2003 1717OHS Training 2003Induction

Risk AssessmentRisk Assessment Key Factors to Assess

consequence: the most likely injury outcome

exposure: how often people are exposed to the risk

probability: likelihood of an accident occurring

OHS Training 2003 1818OHS Training 2003Induction

Job Safety AnalysisJob Safety Analysis (JSA)(JSA)

Job Safety Analysis:

is a safe working procedure involving the assessment of risk

identifies potential hazards and determines safest way to complete tasks

analyses the tasks involved in a job concentrating on: risks, safety, quality, efficiency

integrates health and safety principles and practices into a particular operation

OHS Training 2003 1919OHS Training 2003Induction

Job Safety AnalysisJob Safety Analysis (JSA)(JSA)Job Safety Analysis will:

ensure hazards are identified ensure degree of risk is quantified revise, modify and document work methods give employees input into their own work methods give site team and other contractors

understanding of particular work methods allow site team to monitor/review work methods

and safety

OHS Training 2003 2020OHS Training 2003Induction

roofing steel erection demolition formwork erection

and stripping work near

electricity work in lift shafts

work in stairwells installation of stairs installation of

precast panels installation of fire

services installation of

ductwork

The following tasks involving Class 1 and serious Class 2 hazards always require production of a JSA:

OHS Training 2003 2121OHS Training 2003Induction

JSA DevelopmentJSA DevelopmentJob Safety Analysis can be developed by:

a contractor drafting the JSA in consultation with the principal contractor and the health and safety representative

employees who perform a common task working with their supervisor to draft the JSA

OHS Training 2003 2222OHS Training 2003Induction

JSA - Essential RequirementsJSA - Essential Requirements

site and task specific, not generic sufficient detail to cover the actual task analysis drafted in sequential fashion each identified risk requires a specific control must be readily understood by all members of

site team employee input optimised by formally inducting

workers into a JSA before work starts
