A review was undertaken against the following local legislative requirements: • AS 1657:2018 Fixed platforms, walkways, stairways and ladders • AS/NZS 1891.1:20 20 Part 1: Harnesses & Ancillary Equipment • AS/NZS 1891.2:2001 Part 2: Horizontal Lifeline and Rail Systems • AS/NZS 1891.3: 2020 Part 3: Fall Arrest Devices • AS/NZS 1891.4:2009 Part 4: Selection, use and maintenance • AS/NZS 1891.5:2020 Part 5: Lanyard Assemblies and Pole Straps • AS/NZS ISO 22846.1:2020 Fundamental Principles for a System of Work – Rope Access System • Local State Workplace Health & Safety Act • Local State Workplace Health & Safety Regulations • Managing the Risk of Falls at Workplaces: Code of Practice 2018 (QLD) • Managing the Risk of Falls at W orkplaces: Code of Practice 2019 (NSW) • Managing the Risk of Falls at Workplaces: Code of Practice 20 20 (NT) • Managing the Risk of Falls in the Workplace: Code of Practice 20 20 (SA) • Prevention of Falls from Height at Workplaces: Code of Practice 2020 (WA) • Prevention of Falls in General Construction 201 9 (VIC) 2.1 Risk Management. The audit identifies hazards and control measures that have been prioritised in accordance with o perations requirements. Priority Labelled Colour Risk rating Time frame to Action 1 Significant Immediate Administration controls to be implemented until risk is mitigated 2 Moderate 6 Month Administration controls to be implemented until risk is mitigated 3 Minor 12 Months Administration controls to be implemented until risk is mitigated 5 Height Safety Audit N1720 – Goulburn Square V2. 2 2.2 Risk Assessment. Involves estimating the level of risk – estimating the probability (likelihood) of an event occurring and the magnitude of effects (Consequence) if the event does occur. Essentially risk assessment lies at the heart of risk management, be cause it assists in providing the information required to respond to a potential risk. In a resource management setting, the risk assessment may be used to help manage, for example: occupational hazards (falling, system failures). Key to risk rating : Significant Moderate Minor Likelihood Very High 100 90 70 50 30 10 High Medium Low Very Low Negligible Negligible Very Small Small Medium Large Very Large Magnitude 6 Height Safety Audit N1720 – Goulburn Square V2. 2 2.3 How to use the audit document, and an explanation example shown below: The map reference number (MR) found in the audit findings corresponds with the same number plotted on the roof layout plans. The MR number plotted on the roof layout plan indicates the precise location of the identified hazard No fall protection to roof edge for gutter maintenance requirements – parapet 800mm high (Refer to Reference Guide 8.7 & 10.3) MR -‐ 20 Install guardrail ( 900 mm high) as fall protection to roof edge for gutter maintenance requirements (60m) Appendix 22 Appendix 23 Appendix 24 Priority 1 2.4 Alternative mitigation using the hierarchy of controls can be reviewed. Centre management may review areas of roof that have minimal frequency or plant maintenance access requirements, these areas can be identified as “No Go Zones as an example. 2.5 Disclaimer The assessors believe the information contained within this risk assessment report to be correct at the time of printing.
