Model Work Health Safety Regulations

2. Model Work Health Safety Regulations Module: Common WHS Hazards Workbook p24

3. What are common hazards? • The common hazards likely to be found in most workplaces are considered to be: • Electrical work • Noise • Falls • Hazardous manual tasks • Plant and Structures • Hazardous chemicals Workbook p24 Q.1, 2

4. Electrical Safety The regulation mainly applies to specialist electrical work but has some common workplace application. Electrical Equipment is defined generally but does not include vehicles. Electrical installation is a group of electrical equipment permanently connected (not plug and socket connection). Electrical work covers the work done by licensed people and not tasks such as changing a light bulb. Workbook p24

5. Electrical WorkResidual Current Devices • Must be used if supplying electricity to equipment through a socketoutlet where: • The equipment is used in hostile environments. • The equipment is frequently moved between locations as part of its normal use. • The equipment forms part of an amusement device. Workbook p25

6. Electrical SafetyEquipment and Installations • PCBU must • Ensure unsafe electrical equipment disconnected and repaired or replaced • Inspect and testequipment • Keep records of testing until next tested or permanently removed Workbook p25

7. Electrical Safety: Energised Electrical Equipment • Work on energised electrical equipment prohibited except in certain circumstances. • Must determine whether equipment is energised. • De-energised equipment must not be inadvertently re-energised. Workbook p25

8. Electrical Safety: Overhead & Underground Electric Lines • Ensure that no person, plant or thing at the workplace comes within an unsafe distance of an overhead or underground electric line. • If it is not reasonably practicable to comply, conduct a risk assessment Workbook p25

9. Falls • Manage the risk of a fall by a person from one level to another by: • Ensuring so far as is reasonably practicable that any work that involves the risk of a fall is carried out on the ground or on a solid construction. • Providing safe access to and exit from the workplace or any area within the workplace with the risk of a fall. Workbook p26 & 27

10. Falls • Manage the risk of a fall by a person from one level to another by: • Ensuring so far as is reasonably practicable that any work that involves the risk of a fall is carried out on the ground or on a solid construction. • Providing safe access to and exit from the workplace or any area within the workplace with the risk of a fall. Workbook p26 & 27

11. Falls • If not reasonably practicable to eliminate the risk of falling then minimise the risk by providing adequate protectionsuch as (in order): • Providing a fall prevention device or • Providing a work positioning system or • Providing a fall arrest system Workbook p26 & 27

12. Noise • Ensure that a worker is not exposed to noise levels above the exposure standard. • Audiometric testing is required if a worker frequently needs to wear hearing protection because noise exceeds the exposure standard andin combination with other factors. Workbook p28

13. Hazardous Manual Tasks • Take into account risk factors including: • Postures, force, duration and frequency. • Workplace environmentalconditions, design and layout of workplace. • Systems of work used. • Nature, size, weight and number of persons, animals or things involved in the hazardous manual task. Workbook p29

14. Hazardous chemicals • Correctly labelhazardous chemicals used in the workplace. • Obtain and provide access to Safety Data Sheets (SDS)for workers. • Display safety signs. Workbook p30

15. Hazardous chemicals • Provideinformation, training and supervision to workers. • Identify risks of physical or chemical reaction. • Keep chemicals isolated and stable. • Eliminate or minimise ignition sources. Workbook p30

16. Hazardous chemicals • Maintain aregisterof hazardous chemicals used at the workplace. • Prepare and display a manifestof hazardous chemicals if the quantity requires same. • Display aplacardif the quantity exceeds the placard quantity. Workbook p30

17. Plant and Structures • Controls risks in commissioningand de-commissioningof plant. • Ensure competent persons are used, provide information and undertake inspections. • If guarding is used to control risks a hierarchy from fixed or interlocked to presence guards is followed. Workbook p31

18. Plant and Structures • Ensure that plant not in use does not create a risk to the health or safety of any person. • Ensure that the maintenance, repair, inspection and, if necessary, testing of the plant is carried out by a competent person and in accordance with manufacturer specifications. Workbook p31

19. Plant and Structures • There are additional controls for some plant (e.g. tractors, earthmoving machinery and industrial lift trucks) • Certain plant has to be registered(e.g. tower cranes and lifts ) and also have additional controls Workbook p31

20. Key Changes: These hazards are no longer specified in the WHS Regulations • Abrasive blasting • Spray Painting • Welding • Electroplating • Molten metal Managing the risks associated with these hazards is a duty of a PCBU Workbook p31

21. Activity 4: Case study 1 If the noise is above the exposure standard, the PCBU must provide audiometric testing for the worker • Testing should be carried out by qualified persons and results made available • Depending on results, measures should be taken to reduce exposure (e.g. better maintenance of saw, up-rated hearing protection) Workbook p32

22. Activity 4: Case study 2 • The work meets the definition of a hazardous manual task ie may contribute to a musculoskeletal disorder, including the duration and frequency of the hazardous manual task (Clause 60 (2)(b) WHS Regulations) • What would be reasonably practicable to minimise the risk? • use mechanical picker for products above head height • stack heaviest product on lower racks • use shelf step Workbook p33

23. Activity 4: Case study 3 • Spray painting must continue to be undertaken without risk to health and safety • The hazards must be identified and risk controls used – the airborne contaminants, hazardous chemicals and lead process sections may all apply • Existing practices based on previous regulation and authoritative guidance will form the basis of the state of knowledge about the hazard and how it should be managed Workbook p34

24. Work Health Safety Regulations Module: High Risk Hazards Workbook p35

25. What is High Risk Work? Workbook p35

26. High Risk Work: Requiring a licence • New class • Reach Stackers • Discontinued classes • front-end loaders • front-end loader / backhoes • front-end loaders -skid steer • excavators Workbook p35

27. High Risk Work: Licensing A PCBU must ensure : Workbook p35

28. Demolition A PCBU must give written notice to the regulator at least 5 days before the work commences: demolition of a structure, or a part of a structure that is loadbearing and is at least 6 metres in height demolition work involving load shifting machinery on a suspended floor demolition work involving explosives Workbook p35

29. Asbestos • A PCBU must not carry out, or direct or allow a worker to carry out, work involving asbestos • A PCBU must ensure, so far as is reasonably practicable, that exposureof a person at the workplace to airborne asbestos is eliminated or if not practicable minimised Workbook p35

30. Asbestos • A PCBU must ensure asbestos at a workplace is identified. • A PCBU must assume a material is asbestos if reasonably believed to be so or is inaccessible but believed to be asbestos. • Indicate presence and location of asbestos. Workbook p35

31. Asbestos:Register A PCBU must: Workbook p35

32. Asbestos: Management Plan A PCBU must ensure: Workbook p35

33. Asbestos:Duty to limit use of equipment • The following equipment must not be used on asbestos or Asbestos Containing Material (ACM): • high-pressure water spray (except by fire-fighter) • compressed air • The following equipment must not be used unless controlled: • power tools • brooms • any other implements that cause the release of airborne asbestos into the atmosphere Workbook p35

34. Lead Work Lead risk processes include spray painting with lead paint, abrasive blasting on lead surfaces and foundry process involving melting or casting lead alloys Workbook p35

35. Lead Work PCBU duties include ensuring the following specific control measures are in place: Workbook p35

36. Activity 5: Case study 1 • If a small area (e.g. 5 sq metres) then it may be practicable to remove the sheeting • Another option would be to enclose the damaged area with a solid false wall and put bollards in the potential contact areas • Update the Asbestos register and Asbestos management plan to indicate what measures were taken and to indicate presence of AC sheeting behind the false wall Workbook p36

37. Activity 5: Case study 2 • The PCBU’s general duties apply including the responsibility to ensure that a worker is properly informed and trained has the necessary knowledge and skills to operate equipment • The Managing Risk section requires the PCBU to identify any risks and control them (e.g. complexity of tasks, operator skill and experience, worksite conditions) • The Plant section has requirements for powered mobile plant • Previously published competency standards for this equipment continue to provide sound guidance Workbook p37
