WESTERN AUSTRALIA POLICE BUILDING CODE

CUSTODIAL DESIGN GUIDELINES

REVISION 4 October 2011/ PRINTED 17:22 09/08/2012 1

1 CUSTODIAL DESIGN GUIDELINES1.1 BACKGROUNDUntil convicted by a Court, a person detained by the police is presumed innocent and afforded a number of rights.Custodial facilities enable the police to detain people charged with an offence. The detainee may be in a stimulated/ aggressive condition. Once convicted of an offence, a prisoner may serve their sentence in the facility.

With the number of deaths in custody during the 1980's, the community became increasingly concerned with the

treatment of detainees within both the Prison system and Police Lockups, culminating with the Royal Commissioninto Black Deaths in Custody.

In response to these concerns and the Royal Commission, the Australian Police Ministers Council endorsed anindicative model for the design and operation of custodial facilities in all jurisdictions. See Standard Guidelines forPolice Custodial Facilities in Australia.

Using this model, the Western Australia Police Service developed a set of standards, comprising the

Lockup Management Manual, and Custodial Design Guidelines (previously the Safe Cell Guidelines).ACKNOWLEDGEMENTThe Police Service acknowledges the involvement of the Department of Housing & Works (DHW), previously theDepartment of Contract & Services, Western Australian Building Management Authority, in the development of theSafe Cell Guidelines.

1.2 INTRODUCTIONThe Custodial Design Guidelines

outline the specialised technical requirements for the design of custodial facilities, and standardises the critical building components / elements required in a safe cell. The approved components (see

page 26) have been selected after extensive testing. Ongoing testing will result in regular updating of this

guide.

Variations from these guidelines must be approved by Police Land & Building Management Branch or a delegatedrepresentative.

1.2.1 STANDARD DETAILSA complete set of standard details stamped preliminary will be issued with the brief. The commissioned consultant

shall advise the DHW Contract Manager of the standard details required for incorporation into the contractdocuments. A non-preliminary set of required standard details will be issued. These shall be bound unalteredin thecontract specification.

Please notify the Client Manager (Police) - Client Services - Department of Housing & Works Services of anyerrors or discrepancies in the standard details.

Refer to the Standard Detail section for an index of the current standard details.

1.3 DESIGN PHILOSOPHY1.3.1 CUSTODIAL FACILITIESThe basic philosophy behind the design standards is that all detainees are entitled to certain recognised standards of

care which provide for their basic human rights in an environment that ensures respect for human dignity andsafeguards the individuals health and well-being.

Detainees should have access to certain services and in some cases, be given control over those services, i.e. toilet,drinking water from a hygienic source, etc.

The design should emphasise human interaction between detainees and personnel and allow an appropriate meansof visual and / or audible communications between them.

The custodial facilities cell and office areas should not appear overtly punitive or repressive.

The purpose of a custodial facilities is seen to be for the secure custody / detention of a person while awaiting bail,court attendance, or serving a short sentence. The level of security should reflect the majority of the types of

charges individuals are detained for, rather than the possibility of the need to detain a maximum security prisoner.For example, in an area where the majority of charges relate to offences against good order, cells should bedesigned for that level of security while providing for the environment of that particular region.

1.3.2 SAFE CELLSThe philosophy of safe cell design is to create a cell environment that is:

not degrading or unsafe to the detainee; not unsafe to the police; and assists the police in the supervision of detainees.

1.3.3 DUTY OF CAREThe operational requirements associated with exercising "a duty of care" have resulted in custodial facilities onlybeing provided in District Complexes and isolated stations. In all other stations, holding rooms will be provided toenable short term secure detention for a detainee awaiting charging or transfer to a overnight custody / detentionfacility.

The provision of electronic surveillance is intended as a further aid to assist operational staff in determining the

health of detainees held in custody. These systems are intended to provide on-site surveillance only. The WA PoliceBuilding Code does not address the issue of off-site monitoring.

1.4 DESIGN OBJECTIVES1.4.1 CUSTODIAL FACILITIESWithin a custodial facility there are two secure areas:

Office Areas where detainees are bailed and receive visitors, processed and questioned with access to medical facilities;

Cell Areas where detainees are detained.The size and complexity of these areas varies.

The design of a custodial facilities should take into account:

the purpose of a custodial facilities; the need to restrict public visibility; the ethnicity or culture of the majority of the detainees coupled with the need to detain a variety of cultural

backgrounds;


3/39




the type of offence the person is detained for; the provision to the detainee of an environment which is pleasant and provides access to basic facilities; the elimination of all potential suicide aids within cells; the need to detain a maximum security prisoner without the risk of escape or placing police at risk; that if a courthouse is located in town, the number of detainees held will increase; the recommendations of the final report of the Royal Commission into Aboriginal Deaths in Custody.The design process of such facilities should include consultation with relevant groups.

Detainees considered at risk of self harm, both in the metropolitan area and near country centres, will be transferredto East Perth Custodial facilities.

1.4.2 SAFE CELLSTo design a totally suicide proof cell is almost impossible. These guidelines seek to eliminate the opportunitiespresented in the construction of the cell to inflict self harm.

For ease of supervision and access, cells need to be grouped together and in close proximity to staff areas e.g.

General Office, Charge Room, Staff Entry, etc.

Separation of male and female detainees is required.

1.4.3 CUSTODIAL FACILITIES TYPESCustodial facilities design can be divided into three broad categories, depending on locality. These are considered to

be ideal for the specified area. However, the design should reflect the unique requirements of each town or area,while adhering to the basic philosophy of custodial facilities design.

1.4.3.1 REMOTE AREA CUSTODIAL FACILITIESThe custodial facilities population is substantially aboriginal, usually male and generally detained for offencesagainst good order. There is also the likelihood of a number of sentenced prisoners (trustees) serving short terms ofimprisonment.

The design of the custodial facilities should provide for maximum security prisoners (male, female and juveniles)who can be detained separately with access to secure but separate exercise yards.

The majority of aboriginal detainees / prisoners prefer to share a cell with access to a security compound wherethey can sleep when the weather is hot, and cook and consume food. The security compound should be in line ofsight, or at least within hearing, of the General Office, enabling detainees / prisoners to attract the attention of anofficer.

A visiting area should be provided to allow families to visit detainee / prisoners while maintaining some level ofsecurity. This area should:

be fenced and grassed allowing detainees / prisoners contact visits, or where practicable, visitor access throughthe dual security compound fences;

have trees or shelters; and have a drinking fountain.The custodial facilities should be designed to take advantage of prevailing winds and be sited in such a way as toavoid the harshness of the prevailing climate.

This is recommended for places like Fitzroy Crossing, Roebourne or Laverton. The custodial facilities at Halls

Creek is an example of this design.


4/39




1.4.3.2 COUNTRY CUSTODIAL FACILITIES DESIGNThis is recommended for towns in the wheatbelt or the south west of the State where the custodial facilitiespopulation is predominantly aboriginal. There will be fewer prisoners serving short sentences as each station wouldhave access to a prison. A shaded and grassed fenced visiting area should be incorporated to allow detainees /

prisoners contact visits, or where practicable, visitor access through the exercise compound fence. The extent of the

custodial facilities office area is increased over that provided in a Remote Area Custodial facilities.

1.4.3.3 CITY / MAJOR CENTRE CUSTODIAL FACILITIES - OVERNIGHTDETENTION

This design is recommended for the city / metropolitan area or for larger country towns where the custodial

facilities population is likely to be more transient and diverse. In addition, detainees face a wider variety of charges,often of a more serious nature. There will be fewer prisoners serving short sentences as each station would haveaccess to a prison.The custodial facilities at Kalgoorlie and Joondalup are examples of this design.

1.4.3.4 CITY / MAJOR CENTRE CUSTODIAL FACILITIES - NO OVERNIGHTDETENTIONThis design is recommended for the city / metropolitan area or for larger country towns where the custodialfacilities population is likely to be more transient and diverse. In addition, detainees face a wider variety of charges,

often of a more serious nature. If overnight detention is required the detainees are transferred to another facility.There will be no prisoners serving short sentences.

The custodial facilities at Cannington and Australind are examples of this design.

1.4.4 CELL TYPEThe five types of safe cell, which are described in detail on the activity space data sheets, are:

Padded Cell; General Cell Level A, B and C; Trustee Cell; Police Holding Cell Type A; and Court Holding Cell Type B.

1.4.4.1 DETERMINATION OF CELL TYPE AND NUMBERThe number and type of cells provided in a station varies. However, General Cell Type B and Holding Cell Type Aare considered to be standards.

The following criteria shall be used in assessing the number and type of cells required:

length of custody / detention time; number and sex of detainees; number of detainees held in isolation; availability of other cells; staff numbers available for detainee supervision; distance of cells from continually manned location; number of detainees likely to attempt self harm; type of offences committed by detainees; and number of trustees located in the custodial facilities.

1.4.4.2 CELL COMPONENTSThe following table outlines the building components / elements that shall typically be provided in each cell type.Refer to activity space data sheets for more information.

1.5 DESIGN CRITERIA1.5.1 CUSTODIAL FACILITIESGenerally, the technical requirements for custodial facilities, excluding cells, is described in the Technical CriteriaSection. The following outlines unique or specialised technical requirements for the design of custodial facilities.

1.5.1.1 GENERALThe design shall allow for the easy movement of sick / injured detainees by stretcher from the custodial facilities to

an Ambulance.

All glass in the custodial facilities areas, where detainee may be left unattended, shall be of the approved type andpane size. Elsewhere, a laminated glass shall be used. Each pane of glass shall have the brand name indeliblymarked in one corner.

Walls in heavy wear areas such as Charge Rooms, cell corridors etc. shall have approved anti- vandal paint applied

to a height of 1550 mm.


6/39




The cleaning of custodial facilities, usually undertaken by detainees, often involves the use of considerable volumeof water. Accordingly, adequate drainage both internally and externally shall be provided.

Man holes shall not be located in those spaces where detainees may be left unattended e.g. search room, as they canbe used as an escape route.

1.5.1.1.1 CONTROLSAll mechanical system controls that to be used by the occupiers shall be clearly labelled indicating the name, as perthe brief, of activity space(s) served and the type of system. e.g. Charge Room Exhaust Fan, etc.

All electrical switches that to be used by the occupiers shall be clearly labelled indicating the name, as per the brief,of activity space(s) served and the type of system. e.g. Holding Room Lights, Security Compound Power Point

Isolating Switch, etc. Where a large control panel is provided, typically in the Charge Room, the switches shall begrouped by function.

1.5.1.2 ELECTRICALEmergency lighting and exit lighting shall be installed in all detainee handling areas in accordance with theBuilding Code of Australia.

To minimise the risk of electrocution, should a light fitting be dismantled, lighting to cells and exercise yards shallbe put on separate final sub circuit(s) and fed from 30mA residual current circuit breakers.

1.5.1.2.1 POWERNo GPO's shall be installed in detainee handling corridors or exercise yards.

Electrical accessories located in the Charge Room and the associated Custodial facilities areas shall be Clipsal flush

stainless steel plate type or similar. Secure switch mechanisms to the flush plate with fixing screws.

1.5.1.2.2 COMMUNICATION SYSTEMSThere are a range of communication systems which may be installed in custodial facilities to assist operational staffin determining the well being of detainees held in custody. These systems are intended to provide on-sitesurveillance and monitoring only.

The operation of the systems is to be as simple as possible, so that police officers transferring to a station can be

quickly instructed in its operation.

The activity space data sheets indicate the communication systems, which shall be provided in each activity space.The detailed requirements for each system are described below.

1.5.1.2.2.1 CELL ALARMS AND AUDIO MONITORINGThese systems provide detainees with a mechanism to instigate calls for staff assistance.

1.5.1.2.2.1.1CUSTODIAL FACILITIES ALARM CONTROL PANELDepending on the systems installed, the following shall be incorporated on the Control Panel:

Custodial facilities layout, including illuminated cell numbers / room names. LED's for staff duress alarmbuttons outside area of layout should be located under the layout and clearly labelled. Different colour LEDsshall be used to differentiate between cell and staff alarm points.

Cell Alarm System - illuminated buzzer mute buttons (yellow LED steady), when muted light to remain on; tamper indicator lights (red LED steady); buzzer test switch;


7/39




duress indicator lights (red LED flashing); and power on switch (green LED steady).

Audio Monitoring System - illuminated cell selection switches (yellow LED flashing call request, green LED steady call

accepted);

cell audio monitoring volume controls,

illuminated cell radio / music selection switches, audio monitoring speaker including volume control, and microphone;

Brief instructions (up to 4 lines) covering system(s) operation. An illuminated text display indicating location and type of alarm.

The control panel shall be mounted flush with finished wall or cupboard, depending on location, surface.

The control panel shall be duplicated in the Security / Communications Room or a continually manned location i.e.General Office and the Charge Room, unless these two rooms are immediately adjacent, or the Charge Room isoccupied on a 24-hour basis.

In large custodial facilities, a dedicated printer or Personal Computer shall be attached to the Cell Alarm and AudioMonitoring system for alarm logging. The logging device should be located in the Security / CommunicationsRoom or Communications Room / Alcove and shall be programmed to log the time, date and cell number of alldefined activities. The defined list of activities includes buzzer mute on / off, cell alarm call and reset, cell callacknowledge and cell call reset and tamper. The control panel shall hold up to 1,000 events before over writing thefirst event. The event log shall not be lost if the control panel looses power.

When the station is not manned 24 hours a day the Cell Alarm System and Audio Monitoring System shall becapable of being switched to the Officer in Charge's residence. Provide a duplicate alarm panel in a discretelocation within the quarters. Ensure the buzzer can be clearly heard in the main bedroom. For off-site cellmonitoring see also Duty of Care on page 2.

1.5.1.2.2.1.2CELL ALARM SYSTEMA push button cell alarm enabling a detainee to call for assistance.

When activated by depressing the cell alarm button an intermittent buzzer on the control panel(s) and / or otherwiselocated, shall sound and a yellow LED on the control panel(s) indicating the cell calling and will remain flashinguntil the call is acknowledged. Furthermore, an LED, incorporated in the cell alarm button and in the cell alarmreset button located outside the cell / holding room requiring assistance, shall be illuminated to show the call hasregistered. This alarm shall only be reset outside the cell / holding room in alarm. The intermittent buzzer shall becapable of being muted at the control panel if a detainee is creating a nuisance in using the alarm. The mute shallautomatically reset after a predetermined time period, typically five minutes. The loudness of the buzzer on the

mimic panel in the General Office shall enable staff to clearly hear it. Consideration shall also be given to theinstallation of a small ceiling mounted strobe light activated when the buzzer sounds. The mute must automatically

reset upon the alarm being reset at the alarm reset button. Muting the Cell Alarm buzzer shall not alter the operationof the indicating LED, which shall remain on until the reset button is depressed and the alarm call cleared from thesystem.

The alarm call shall electrically latch, so that only momentary use of the alarm push button in the cell will activatethe alarm, remaining on at the both nominated locations until the alarm reset button outside the calling cell / holding

room is depressed.

All wiring to the cell alarms in the detainee areas (including cells / holding rooms) is to be at maximum 24V (a.c. ord.c.).

The cell alarm system shall be tamper monitored at the control panel.

For details of the cell alarm push-button plate see page 25.

1.5.1.3 FIRE PROTECTION CRITERIA

1.5.1.3.1 CLASSIFICATIONClassification as defined in the Building Code of Australia for:

Custodial facilities is Class 3; and


12/39




Police Stations is Class 5.

1.5.1.3.2 GENERAL - BUILDING CODE OF AUSTRALIACustodial and Police Stations are to comply with the Building Code of Australia and Annexure 1 Building Code

Alternative Solution For Custodial Accommodation Police Stations Condensed Report. The Design Requirementsare to be incorporated into cell and Police Station design. Where items are not listed and/or specified in the reportsthey are to comply with the Deemed to Satisfy (DTS) provisions of the Building Code of Australia.

1.5.1.3.3 EGRESSThe Custodial facilities shall be designed to enable detainees, under police supervision, to exit the custodialfacilities into open space with the distance of travel minimised. A cell or holding room door should be within 6m ofeither an external exit or a point enabling a choice of two exit paths. A direct external exit shall be provided fromthe cell area of a custodial facility. This exit shall enable the evacuation of the custodial facilities should the stationbe on fire and should be in addition to the normal exit via the Charge Room. These doors shall be keyed alike with

the cell doors. All doors shall open 180oand be able to be latched in the open position.

The CSIRO Smoke Exhaust assessment, refer to Smoke Exhaust System on page 13, established that the Trusteecells should be fire isolated from the other cells because of the higher fire loading in the Trustee cells. The door of

the fire-isolated cell shall be non-lockable, but the corridor in the vicinity of this cell shall be provided withlockable doors/gates. This allows the occupant of the Trustee cell to escape from the fire isolated compartment inthe event of a fire, but he or she is still locked in once outside of the fire affected cell.

Egress Requirements1. The custodial facilities are to be designed in accordance with the Alternative Building Solution (Annexe

1). Where the cell numbers are greater than 2, an additional egress point direct to open space is to beprovided;

1.5.1.3.5.1 SMOKE DETECTIONSmoke detectors / fire alarms shall be installed in all areas of the Police Station including custodial facilities.

Consideration, based on life cycle cost, maintainability and reliability, should be given to the use early warningsmoke detectors

The lack of combustible materials in cells and exercise yards means that smoke detectors provide more appropriateprotection than thermal detectors. One detector per cell or exercise yard is preferred and:

located within the return or exhaust air ducts; duct mounted detectors shall be accessible via manholes located outside the cell / exercise yard area; and integrated with the mechanical services design.Additional smoke detector(s) shall be provided in high points in the ceiling where smoke from the cells or exerciseyards could collect. Such detectors should be no closer than 1500 mm from any openings in the cell exercise yardfronts large enough for a person's arm.

The system shall sound an alarm and illuminate a location indicator on a control panel located / duplicated in theSecurity / Communications Room or a continually manned location i.e. General Office and the Charge Room,unless these two rooms are immediately adjacent, or the Charge Room is occupied on a 24-hour basis. When thestation is not manned 24 hours a day, the alarm shall be capable of being switched to the Officer in Charge'sresidence.

The alarm shall be incorporated in the Electronic Control System. See Security Systems section in the TechnicalCriteria.

1.5.1.3.5.2 SMOKE EXHAUST SYSTEMSmoke extraction from cells, holding and waiting rooms shall be designed in accordance with the following

guidelines

1.5.1.3.5.2.1BackgroundThe following design guide is based on the outcomes of a smoke exhaust assessment carried out by the CSIRO withassistance from the WA Police Service, Department of Housing & Works (previously Department of Contract andManagement Services) and the WA Fire Brigade. The CSIRO assessment was carried out to establish the minimum

smoke exhaust rates in various cells, including holding rooms, taking into account the likely fire load and size ofthe cell(s) or holding room(s). The assessment included computer modeling and real fire tests using the flame

retardant "Just Kidding" - Safe Guard - Proban P.U. S300" cell mattress

Operational aspects relating to fire safety are to be in accordance with the Building Code of Australia.

1.5.1.3.5.2.2Description of the cells.The smoke exhaust design guidelines are based on the following assumptions:

the Trustee Cells are overnight and short-term detention cells where trustee detainees are locked in the cellovernight but not during the day.

the General Cells are overnight and short-term detention cells and the occupants are locked in their cells at alltimes.

the holding / waiting rooms are short-term detention cells and the occupants are locked in the cells during theday, but there is no overnight detention.

the floor areas of the cells, holding / waiting rooms vary between 10 m2and 20 m2.

1.5.1.3.5.2.3Smoke Exhaust Options


14/39




Smoke exhaust options include mechanical exhaust and natural smoke exhaust through the ceiling vents and wallvents. Wall vents are not as efficient as ceiling vents and therefore require larger areas to achieve the requiredresults. The smoke exhaust requirements and the various options are:
