Electrical Safety Management Procedure (ESMP)

Purpose

This procedure describes how the Australian National University (ANU) manages electrical safety in the workplace, to ensure the safety of all staff, contractors, students and others from electrical hazards encountered at ANU.

This procedure ensures legal and other obligations of the Work Health and Safety Act 2011 (Cth), the Work Health and Safety Regulations 2011 (Cth) and the University’s Work Health & Safety (WHS) Management System are met. This procedure is linked to the Australian National University’s Work health and safety policy and is one of the Safe Work Procedures within the WHS Management System.

This procedure will form the basis for all electrical work carried out at the ANU. This procedure will also form the basis for local area procedures.

Responsibility to comply with these procedures lies with all ANU staff and it will be the responsibility of supervisors/managers to ensure compliance.

Scope

1. This procedure applies to the following electrical safety management requirements:

1. All electrical work on the University’s electrical installations. This work should also meet requirements within the Campus Buildings Requirements Manual; and shall only be undertaken by a competent person assigned the appropriate category (refer Table 2).
2. Electrical work undertaken at all University campuses shall comply with all relevant Commonwealth, State and Territory legislation, Codes of Practice, Australian Standards, guidance material and best practices.
3. Inspection, testing and tagging of equipment.
4. Work on ‘live’ electrical installations and equipment is to be avoided whenever practical;

38. The Australian Standard AS/NZS 3112 specifies larger pins and differently shaped ground pins for power points with current ratings of 15, 20, 25 and 32 amps. Power points are also available specifically for external use - these are required to have a special weather proofing rating (to a minimum of IP67).
39. Power boards (Electric Portable Outlet Devices, EPODs) where used, shall incorporate a current limiting device (circuit breaker) and, where practical, be mounted with the outlets in the vertical plane and protected from mechanical, electrical or water damage
40. CAUTION: Extension cords should only be used as a temporary (not permanent) solution and are not to be installed as fixed wiring.
41. CAUTION: Double adaptors and similar are NOT to be used in the University, as they have no overload protection.
42. All electrical equipment requiring in-service inspection and testing which:

127. has not been tested; or
128. has failed testing; or
129. is overdue for testing; or
130. is within 1 month of a test expiring.

Must not be used until it is tested in compliance with AS/NZS 3760 : In-service safety inspection and testing of electrical equipment.(ref Table 1)

43. CAUTION: Battery chargers, power supply units and transformers that have been disconnected from the device MUST be removed/isolated from power source when not in use. E.g. phone chargers, laptop chargers. Battery powered devices should not be left on charge longer than the manufacturers recommended charge times. Items on charge should not be covered, placed on flammable surfaces and should be located in well ventilated area.

Privately Owned Electrical Appliances

The use of privately-owned electrical equipment in University workplaces (except Halls of Residence and University House) is not permitted unless it is inspected, tested and tagged in accordance with Table 1 of this procedure.

44. The cost of testing and tagging by a competent person or external company is to be met by the appliance owner.
45. The use of privately-owned electrical equipment is not permitted for use in a laboratory or workshop regardless whether it is electrically tested and tagged or not. (See exclusions)
46. The University has provided power outlets, for the use of visitors. Privately-owned electrical appliances (for example, laptop computer or phone charges) may be used at these outlets provided that it complies with the appropriate Australian or international electrical manufacturing standard. The equipment must be inspected and maintained by the owner and be in a safe condition.
47. CAUTION: Not all power outlets at ANU are RCD protected.
48. WARNING: Battery chargers are not to be left connected to power outlet if not connected to a device. This can pose a fire hazard.

Section 1: Pre-work Operational Procedure

49. All electrical equipment within the ANU, or any electrical equipment used by ANU workers (see exclusions) which includes:

1. New equipment placed into service for the first time;
2. Already in-service electrical equipment;
3. Electrical equipment that has been serviced or repaired;
4. Second hand electrical equipment returning to or being placed in service; or
5. Electrical equipment available for hire.

Electrical Lockout Procedures

50. Isolate, De-Energise, Lockout and Tag out Plant

Isolation procedure

51. Isolation procedures in each workplace may vary because of differences in plant, power sources, hazards and processes. However, every isolation procedure should include the following basic steps:

Shut the plant down

52. The operation of a single switch or valve can usually shut down plant that has a single energy source. More complex plant may have to be shut down in a sequence, for example, one conveyor before another, or by shutting down several energy and control sources.

Identify all energy sources and other hazards

53. Isolation procedures should identify all energy sources likely to re-activate the plant and place people at risk.

The energy sources include:

131. Electricity, including mains, solar, UPS, battery and generator;
132. Fuels;
133. Heat;
134. Steam;
135. Fluids under pressure, such as water, air or hydraulic oil stored energy accumulate hydraulic pressure, battery power, air tanks and gravity;
136. Radiation; and
137. Fail safe devices – designed to move components when power fails.

54. Where possible, ANU workplaces should use original designer and installer 'as built' diagrams of plant installations showing location and details of various plant components, isolation points, switches, valves, energy lines, pipes, power sources and control points, including computers, as part of the isolation procedures.
55. If original designer and installer 'as built' diagrams of plant installations are not available, workplaces should develop new diagrams/photographs.
56. Shutting the plant down may require identifying other hazards and minimising or removing the risk of injury. For example, associated equipment may need to be locked-out to prevent re-activation, or valves on pipes and lines carrying gases or fluids may need to be locked shut or blanked off.
57. Depending on the plant, other hazards may include:

138. Hazardous substances, such as gases, acids, alkalis and solvents;
139. Falls;
140. Burns;
141. Asphyxiation from dust, fumes, low oxygen levels, confined spaces; and
142. Impact.

Identify All Isolation Points

58. All plant that could require an isolation procedure should have appropriate isolation points for all energy sources clearly marked so work on the plant can proceed safely.
59. It is important to identify all isolation points in a system, as it may be necessary to use a local isolator to shut down a specific part of the machine, a motor for example, while the rest of the associated plant remains in operation.
60. WARNING: Emergency stop buttons, lanyards and similar stop devices on their own are not satisfactory isolation points. It is dangerous to rely solely on emergency stopping devices, because they are not designed for frequent use, cannot be locked out in all cases and may allow energy to be re-activated. They may also allow control circuits to remain live. Consider remote control rooms and process computers when identifying isolation points.

Isolate all Energy Sources

61. The person in control of the ANU workplace should also identify a person (or persons) who knows and understands the complexities of the plant and appoint that person (or persons) to coordinate the isolation of all energy sources and hazards of the plant.
62. Identify and isolate all electricity sources, bearing in mind some plant will have several control stations and sections of plant may have independent electricity sources. If programmable logic devices control the equipment, then it is essential to use local isolating switches to achieve secure and safe isolation. Do not rely on programmable logic devices for the isolation of equipment, unless the device has been certified as a programmable logic controller (PLC) which can reliably isolate equipment by activating its controls.

Exception:

63. Where equipment connects via a plug and socket, isolation can be carried out by the equipment operator.
64. If equipment is hard wired (permanent connection), or has multiple sources or power, only a competent person, such as an electrician, should isolate and disconnect all electricity supply to an item of plant, not just the control circuit.
65. Having a competent person isolate and disconnect electricity supply makes sure equipment cannot be energised via another source or control system.

De-energise All Stored Energies

66. Take any of the following steps necessary to guard against energy remaining in the plant after it has been isolated from its energy sources:

143. Inspect the plant to make sure all parts have stopped moving.
144. Install ground wires.
145. Relieve trapped pressure.
146. Release the tension on springs, or block the movement of spring-driven parts.
147. Block or brace parts that could fall.
148. Block parts in hydraulic and pneumatic systems that could move from the loss of pressure.
149. Bleed the lines and leave vent valves open.
150. Drain process piping systems and close valves to prevent the flow of hazardous material.
151. Use a blank flange to block a line where there is no valve.
152. Purge reactor tanks and process lines.
153. Dissipate extreme cold or heat, or provide protective clothing.
154. If stored energy can re-accumulate, monitor it to make sure it stays below hazardous levels.
155. Dissipate stored electrical energy in capacitors etc.
156. Locking out all isolation points.

67. A wide range of devices are available for locking out energy sources and other hazards. As well as interlocked guards, lockout devices can include:

157. Padlocks and chains;
158. Safety lockout jaws or hasps which use multiple padlocks;
159. Switches with a built-in lock; and
160. Lockouts for circuit breakers, fuses and valves.

NOTE: Only devices that incorporate a lock or can accommodate one or more padlocks are suitable for locking out energy sources.

One Person, One Lock

68. If more than one person is working on the same plant, each person should attach their own lock to prevent the energy isolator being opened before all locks have been removed or opened. The isolation procedure should identify common lockout points to make sure energy cannot be restored while someone is still working on the plant.
69. If two or more people are working on plant that is isolated through several lockout points, each person should attach a lock and tag to each lockout point.
70. The need for multiple locks on each lockout point can be avoided by using a lock box. The lock box system uses only one lock at each lockout point. Keys to the locks of the plant's lockout points are inside a box which is locked by all the individual locks of people working on the same plant.

One lock, one key

71. Each person working on the plant should have their own lock, key and tag. There should be no duplicate key available for any lock, except a master or duplicate key for use in an emergency. The master or duplicate key should be secured and not readily available except in an emergency. (See WHS code of practice – Managing Risks of Plant and Equipment.)
72. During plant inspection, repair, maintenance, cleaning or adjustment, each person should only hold the one key to their lock. That person is responsible for both locking and unlocking the lockout device.

Multiple Energy Sources

73. If more than one energy source or hazard has to be locked out to enable safe shutdown of the plant, the same person should hold the single key to each lockout device.

Tagging

74. WARNING: A tag is not an effective isolation device. A tag acts only as a means of providing information to others at the workplace. A lock should be used as an isolation device, however where a lock is used a tag should also be incorporated to explain the purpose of the lockout.

Commonly used warning tags include:

Personal danger tags

75. A personal danger tag on the isolation devices of an item of equipment is a warning that the equipment is unsafe and that operating the equipment may endanger the person who attached the tag. Personal danger tags should be restricted to employees who will be working on equipment. Destroy all disposable personal danger tags after use.
76. A personal danger tag should be attached to an isolator in a visible position whenever the isolator is used to lock out an energy source to allow work to be done.
77. The personal danger tag should accompany each lock used in an isolation procedure and should identify the person who put the tag and lock in place, provide contact information of the person whom put the danger tag in place, the time and date this occurred, state the reason for the danger tag being placed and identify the item of plant that is being isolated.
78. The person doing the work should fasten their personal danger tag on all lockout devices involved in the isolation procedure. If more than one person is involved in the work, each person should attach their own lock and personal danger tag to the lockout device. Locks are available that have a personal danger tag incorporated to make sure the tag cannot be removed by any person other than the person who attached it.

Removal of Tags

79. Removal of a personal danger tag from an isolating device should be carried out as soon as possible after completing the work.
80. WARNING: Only the person whose name is written on a personal danger tag can remove the tag. This should be done before leaving the worksite at the end of the shift. If work is to continue the new worker will install a tag.
81. The workplace isolation procedure should include the course of action if a person does not remove a personal danger tag before leaving the worksite.
82. Where work on plant is not completed by the end of a working shift and the plant is required to remain isolated, arrangements should be made for out of service tags to be placed on each isolating point before the removal of personal danger tags. If work on the plant is to continue during the next shift, there should be a 'hand over' briefing by the shift leaving the site to the shift taking over the work. The briefing should include the status of the work and the removal or replacement of personal danger tags and locks.

Out of Service Tags

83. An out of service tag is a notice that states appliances or equipment are out of operation for repairs and alteration, or plant that is still being installed.
84. WARNING: Do not operate an appliance or equipment with an out of service tag attached. Out of service tags should not be relied upon to provide personal protection.
85. An out of service tag on an item of plant shows that the plant is unserviceable and should not be used. An out of service tag can be attached to non-powered plant such as ladders, jacks and trolleys and powered plant. Out of service tags should be attached to the main controls if possible, or to a prominent part if there are no controls, such as with damaged ladder.
86. A competent person with specific knowledge relating to the plant should attach out of service tags. Out of service tags should be placed on devices which isolate energy sources only when those devices are set in the 'off' or 'safe' position.
87. Before attaching an out of service tag, all required details on the tag should be clearly entered in the spaces provided, with emphasis given to the reason for placing the tag. Tags should be securely fixed so they are clearly visible.
88. Except in an emergency, out of service tags should only be removed by a person who is both familiar with the plant and fully understands why the tag was placed.
89. In the absence of any personal danger tag or lock, removal of an out of service tag releases plant for use, and should not be done before ensuring that:

161. All people known to have been working on the plant are clear of the plant.
162. An inspection of the plant shows that all machinery guards are in place, that all protective devices are functional, that all maintenance tools and aids have been removed, and that the equipment is safe for normal use.

90. Out of service tags should provide a clear 'DO NOT OPERATE' warning, and warn that failure to obey may cause damage to the equipment and/or injury to a person. It is essential that isolating mechanisms which have out of service tags attached are not switched, manipulated or interfered with while the tags are in place.
91. Personal danger tags and out of service tags should not be used together on the same item of equipment because they relate to different circumstances. An out of service tag should be removed when a personal danger tag is added, and vice versa. On completion of maintenance, cleaning or other work, remove the tags before the plant returns to operation.
92. CAUTION: Only those qualified people who are familiar with the equipment can remove the CAUTION tags.

Testing Isolation Procedure

93. After plant has been shut down, locked out and tagged, all isolated power sources should be tested, first with appropriate instruments and then by trying to re-activate the plant, before any person attempts to start work.
94. A person who understands the complexity of the plant, or parts of the plant should do testing and starting the plant, including remote control stations and computers.
95. CAUTION: It is not safe to assume an isolator has locked out an electricity source just because the isolator is in an open position. While the open position should create an air gap between contact points, electricity can weld the points together. If the contact points become welded together, the points remain connected even when the isolator appears to be open.
96. Work on the plant should not begin until tests have confirmed it is safe to do so. Before using any instruments that test isolation procedure, employers should make sure the testing equipment is calibrated and working properly.

Other Hazards:

97. Once electrical isolation has been achieved there are other hazards to consider such as:

163. Is confined space entry required.
164. Is working at heights required.
165. Will hazardous substances be used or encountered.
166. Is noise going to be an issue.
167. Manual handling hazards.
168. Fatigue and musculoskeletal hazards.
169. Hot and cold hazards.
170. Environmental hazards and risks.
171. Other hazards and risks as identified.
