Part E3 Lift installations

Part E3 Lift installations

Introduction to this Part

This Part is intended to ensure that lifts are safe to use, including by people with a disability and emergency services personnel. This Part is also intended to ensure occupants know when lifts should not be used (e.g. during a fire) and, in the event of lift malfunction, for conditions in a lift car to remain tenable and occupants to able to call for assistance.

Objectives

2019: EO3

All people using a building, including those with disabilities, must be able to travel safely in a lift. Lifts must help emergency services personnel to evacuate sick or injured people. Lifts should also help the fire brigade to transport firefighters and their equipment.

Functional Statements

2019: EF3.1

E3F1 only applies where a passenger lift is provided. Under E3F1(a), the lift must be suitable for people with a disability.

2019: EF3.2

In high-rise buildings and those Class 9a buildings that have patient care areas above road or open space level, a lift must be able to assist emergency services personnel such as:

  • ambulance officers carrying equipment to assist a sick or injured person; and
  • the fire brigade with equipment.

Lifts in these buildings must also assist with the evacuation of any person unable to use a stairway unassisted.

2019: EF3.3

A building having a passenger lift is to be provided with measures to alert occupants about the use of the lift in an emergency.

Performance Requirements

2019: EP3.1

Under E3P1(a), where emergency lifts are required under E3P2, at least one of those required lifts, to the degree necessary, must have stretcher facilities. Where there is a single emergency lift it must be the stretcher lift.

Under E3P1(b), where passenger lifts are provided (and E3P1(a) does not apply because an emergency lift is not required under E3P2), at least one of those passenger lifts must have stretcher facilities.

When a person becomes injured in a building, a stretcher may be needed to evacuate them.

E3P1 does not contain any specification of what is acceptable as “stretcher facilities”. However, as a guide, E3D3 contains suitable dimensions for a lift car required to accommodate a stretcher.

 

2019: EP3.2

In high-rise buildings (i.e. with an effective height of more than 25 metres), and those Class 9a buildings which have patient care areas above road or open space level, a lift must be available to aid the fire brigade and any other emergency services personnel.

Emergency lifts must service the same floors as any other lift. Therefore, if a level such as a plant-room level does not have any lifts serving it, there is no necessity to provide an emergency lift service to that plant-room level.

2019: EP3.3

A suitable notice must be provided, or other measure taken, to alert people about the use of a lift during a fire or other emergency. This applies to all passenger lifts.

2019: EP3.4

E3P4 should be read in conjunction with Part D4. Where access to upper floors is provided by lifts to satisfy Part D4, or where lifts are installed in a building that is required to be accessible under Part D4, those lifts must be suitable for use by people with a disability.

E3D7 and E3D8 provide information on limitations to the use of various types of passenger lifts in certain situations. They also provide information on the size of lift cars and platforms, the application of features such as lighting, door opening widths, handrails and audible and visual information for specific lift types.

Verification Methods

2019: EV3.1

E3V1 is a means to verify that an automatic warning system complies with E3P2 to alert occupants about the use of lifts in an emergency, and requires a sound system that activates when a building fire is detected. This method acts as an alternative to the Deemed to Satisfy method of using signage to alert occupants about the use of lifts in an emergency. E3V1 nominates that the automatic warning system must be designed to cancel the normal operation of lift call buttons, thereby compelling occupants to use regulated evacuation routes. The automatic warning system must be capable of being manually overridden by emergency personnel in order to minimise any impact on fire-fighting activities.

2019: EV3.2

E3V2 is a means to verify that an emergency alert system for lifts complies with E3P3 by providing an automatic warning for the use of a lift during an emergency. 

Deemed-to-Satisfy Provisions

2019: E3.0

To clarify that E3P1 to E3P4 will be satisfied if compliance is achieved with E3D2 to E3D12 in the case of all buildings, Part G6 in the case of occupiable outdoor areas and, for public transport buildings, Part I2.

Where a solution is proposed to comply with the Deemed-to-Satisfy Provisions, compliance with E3D2 to E3D12, Part G6 and Part I2 achieves compliance with E3P1 to E3P4.

Where a Performance Solution is proposed, the relevant Performance Requirements must be determined in accordance with A2G2(3) and A2G4(3) as applicable. (See commentary on Part A2).

2019: E3.1

E3D2 requires that an electric passenger lift and an electrohydraulic passenger lift installation in a building comply with Specification 24 for building-related matters. This would include ventilation and lighting of the lift car and foyer access as well as ventilation of the lift shaft.

The conditions in the lift car and the lift shaft machinery are dependant on the conditions in the lift shaft. If the lift shaft air temperature can be elevated due to the effects of the sun, then adequate treatment such as ventilation may be required to maintain safe conditions in the lift shaft along with satisfactory operating temperatures for the lift car machinery and car.

An electric passenger lift may also be a combined electric passenger and goods lift.

An electrohydraulic passenger lift may also be a combined electrohydraulic passenger and goods lift.

2019: E3.2

To require lifts to be able to accommodate a stretcher.

Under E3D3(1), stretcher facilities are required in one of the emergency lifts required by E3D5. Where no emergency lift is required and passenger lifts are provided, then stretcher facilities are to be provided to one lift serving any storey above an effective height of 12 metres.

Where there is just a single emergency or passenger lift that lift must have stretcher facilities.

E3D3(2) sets out the minimum dimensions of a lift car to accommodate a stretcher. It is allowable to have a protuberance or an openable recess in the lift car to accommodate a stretcher with the dimensions stated.

2019: E3.3

To alert people to the dangers of using lifts during a fire.

E3D4 applies to all passenger lifts, even if the building has an effective height of less than 12 metres.

A suitable warning sign must be provided near a lift or lift call button, so that people do not use a lift at an inappropriate time (note that E3D4(3) and Figure E3D4 specifies that such a sign must warn occupants against lift use during a fire).

E3D4 does not apply to small lifts, such as “dumb waiters”, not intended to accommodate a person.

E3D4(3) and Figure E3D4 specify the nature, content, and minimum dimensions for the warning sign. The size and colour of the lettering on the sign are important, so that the sign can be easily read and stand out against the background colour.

2019: E3.4

To require that lifts be suitable for their purpose and also be available for emergency services personnel.

E3D5(1) to (4) only applies to buildings with an effective height above 25 metres, and in certain Class 9a buildings. E3D5(2) clarifies that a passenger lift may be used as an emergency lift, provided it satisfies the other provisions of E3D5.

An emergency lift must serve all the floors in a building served by passenger lifts but is not required to serve other floors such as those containing only plant and equipment.

One emergency lift is not required to serve all floors in a building. Just as one bank of passenger lifts may serve certain floors, so may emergency lifts.

E3D5(3)(a) requires that where more than one passenger lift serves a floor, at least two emergency lifts must serve that floor.

E3D5(3)(b) requires that if the passenger lifts are in separate shafts, the emergency lifts must also be in separate shafts. This maximises the probability of the emergency lifts operating in an emergency, by minimising the risk that a fire in one shaft will endanger both lifts. It also excludes from its requirements a lift that is within an atrium and not wholly contained within a shaft.

To protect people using an emergency lift during a fire, E3D5(4) requires it to be within a fire-resisting shaft in accordance with the requirements of C3D11.

The E3D5(4)(b)(i) dimensions for an emergency lift in a Class 9a building serving a patient care area are to accommodate a stretcher or bed for non-ambulatory patients.

The E3D5(4)(b)(ii) requirement for an emergency lift in a Class 9a building serving a patient care area to be connected to a standby power supply (if the building has such a system) is in recognition of the risk likely in the event of a power failure.

Under E3D5(4)(c), all emergency lifts serving buildings with an effective height of more than 75 metres must be capable of carrying a weight of at least 600 kg or 900 kg if provided with a stretcher facility. This recognises the increased difficulties emergency services personnel (particularly fire brigade officers) face in carrying heavy equipment to such heights.

2019: E3.5

To require that safe movement be available to and from lift landings.

E3D6 requires access to and egress from lift landings to comply with Parts D2, D3 and D4, including access for people with a disability.

2019: E3.6, Table E3.6a, Table E3.6b

Passenger lift types, limitations and required features

E3D7 Passenger lift types and their limitations

E3D7 only applies when a passenger lift is required by D4D4(b) for vertical movement in a building required to be accessible. E3D7 details the limitation of each defined type of lift.

There are a number of limitations on the use of stairway platform lifts including that they must not be installed if it is possible to use another type of passenger lift described in E3D7.

Some types of lifts must not be used in high traffic public use areas of certain buildings. For example, a stairway platform lift or a low-rise, low-speed constant pressure lift must not be used at the entry to a theatre. However, these types of lifts may be used to provide access to the stage in a theatre because the access to the stage is not considered to be a high traffic public use area.

E3D8 and specific components of AS 1735.12 referenced by E3D8 require passenger lifts to have specific features.

2019: Table E3.6a, Table E3.6b

Passenger lift types, limitations and required features

E3D8 Accessible features required for passenger lifts

E3D7 only applies when a passenger lift is required by D4D4(b) for vertical movement in a building required to be accessible. E3D7 details the limitation of each defined type of lift.

There are a number of limitations on the use of stairway platform lifts including that they must not be installed if it is possible to use another type of passenger lift described in E3D7.

Some types of lifts must not be used in high traffic public use areas of certain buildings. For example, a stairway platform lift or a low-rise, low-speed constant pressure lift must not be used at the entry to a theatre. However, these types of lifts may be used to provide access to the stage in a theatre because the access to the stage is not considered to be a high traffic public use area.

E3D8 and specific components of AS 1735.12 referenced by E3D8 require passenger lifts to have specific features.

2019: E3.7

To require fire service controls for lifts serving any storey above an effective height of 12 m.

By having all lift cars serving any storey above an effective height of 12 m fitted with fire service controls there is no confusion as to which lift car can be used by emergency services personnel, and it also increases the reliability of having an operational lift in the event of an emergency (where more than one lift is provided). This does not require lifts to be increased in size to take a stretcher.

Fire service controls include a fire service recall control switch complying with E3D11 and a lift car fire service drive control switch complying with E3D12.

2019: E3.8

To require the installation of a lift where residents of a Class 9c building are on levels not having access to a road or open space.

E3D10 applies to Class 9c buildings. It requires all levels of residential care buildings to have direct access to a road or open space via a ramp or lift capable of carrying a stretcher. This is to overcome the difficulty experienced by some residents negotiating stairways and enable the use of stretcher facilities on all levels of a residential care building. It also assists with the daily functioning of the building, especially with the use of mobile baths and other equipment.

2019: E3.9

To specify the fire service recall control switch required for passenger lifts.

E3D11 details the switch, labelling, key and operation procedures for a fire service recall control switch. A group of lifts is where a number of lifts are under the same sequence controls.

2019: E3.10

To specify the fire service drive control switch required in all passenger lifts.

E3D12 details the switch initiation, labelling and operation for the fire service drive control switch.

A multi-deck installation is a lift car with passengers on more than one deck. The most common multi-deck lift car has two levels opening to two landings at each storey served.
