For the determination of capacity requirements of mortuaries refer to the recommendations further on in this guide. This guidance document relates to mortuaries located within and serving hospitals, with respect to persons that die due to natural causes in that hospital.
This guidance excludes mortuaries dealing exclusively with cases that require medico-legal investigation of deaths from unnatural causes. Post mortems conducted in hospital mortuaries should be limited to conducting investigations and procedures where no medico-legal investigation is required and death from natural causes is suspected. Hospital deaths from natural causes and those suspected to be of unnatural cases should not be managed in the same facility unless the hospital mortuary is equipped to comply with the specific staffing infrastructure and operational requirements as they relate to the legislated forensic pathology services mandates, etc.
The requirements for forensic-pathology service mortuaries are not exhaustively detailed in this document. It is also noted that some hospitals may opt to contract out the removal and storage of decedents to private undertakers and these hospitals may require only the minimum in terms of refrigerated body storage.

PLANNING AND DESIGN

Introduction

All state-run mortuary facilities fall within the domain of the Department of Health, both National and Provincial; and in an effort to provide engineers and architects who are required to either design new facilities or upgrade existing facilities, this document provides the minimum standards necessary to comply with existing legislation.
This document will provide designers of this type of facility with guidelines as to what is required in terms of the following:

  • Type of service and package of care being provided
  • Mortality rate
  • Access and egress
  • Discreet management of human remains
  • Size and dimensions of the actual facility
  • Positioning of mortuaries within hospitals
  • Finishes of surfaces in these facilities
  • Water-supply requirements
  • Drainage requirements
  • Electrical supply and lighting requirements
  • Installation requirements for equipment and services
  • Body-storage requirements
  • Body-handling facilities
  • Body-holding areas
  • Body-viewing area
  • Autopsy equipment (tables)
  • Air conditioning and ventilation requirements (for infection and indoor air quality control)
  • Security of the facility

In addition to the items listed above, it is also necessary to consider the needs of visitors to these facilities, particularly those wishing to, or who are required to, identify bodies. In line with this, it is also necessary to take the handling of bodies into consideration as it pertains to issues of patient dignity.
Forensic pathology mortuaries are not exhaustively described in this document, although the majority of hospital mortuaries do have basic facilities for general autopsies that are not medico-legal in nature. A forensic pathology service mortuary has laboratory facilities attached, as well as legislated operational requirements that are outside the scope of regular mortuaries found in hospitals. It should be noted that there are a number of principles that hold true for both hospital and forensic pathology mortuaries.
Compliance with the requirements of the Occupational Health and Safety Act (Act 85 of 1993 as amended) are to be complied with at all times during the design of a mortuary.

Location of the Mortuary and Access Routes

The position of the mortuary in a hospital should be such that the mortuary is easily accessible to mortuary staff and related service providers without presenting either aesthetic, emotional or ethical problems for unrelated hospital staff, patients or visitors. Visitors to the mortuary, however, should be provided with clear and direct access to the mortuary upon arrival at the hospital, without having to travel unnecessarily through hospital departments.
Where bodies are moved into or out of the mortuary, they should not be moved through general public-access areas. Appropriate routes would include technical service or goods corridors and through the hospital’s support services yard.
Special considerations should be given to plans for contingency access to the mortuary in the event of case-load surges, which may result from disasters.
Bodies should not be held for any period in any locations between the body-holding rooms within clinical areas and the mortuary.
Where a mortuary unit is used jointly between the hospital and the local authority it is beneficial for the mortuary to be in a building separate from the main hospital building.
The delivery of bodies to the mortuary and their subsequent removal from the facility is to be such that it is carried out in a manner that is not visible to the general public, preferably in a covered and enclosed area.
While siting and access are important aspects when locating a mortuary, it is also important to provide the mortuary with pleasant surroundings in order to promote the dignity of those working in or visiting the mortuary.

Facility Capacity

The layout and size of a mortuary is largely determined by the number of bodies stored and whether body storage needs to be in cabinets or in refrigerated rooms.
In order to determine the storage capacity of a hospital mortuary, it is recommended that historical data, where available, should be used. In the South African context, it is suggested that a storage capacity of between 5 and 10 bodies per 100 beds should be used. This varies with the rural or urban location of the facility. This capacity should not take into account the need to store bodies from deaths which are not hospital-related, typically motor-vehicle accident deaths and deaths from criminal activity. Requirements for contingency storage capacity related to disaster management should be considered. The body storage capacity required can be estimated on the basis of the number of deaths per year in the hospital, the length of time of holding and the required body store occupancy rate.

The number of body trays can be calculated from the equation:

BT=(D×S)/(365×R)

Where:
BT = Number of body trays
D = Number of deaths per year requiring body trays
S = Average length of stay (in days)
R = Required body tray occupancy rate


Example
The number of body trays required in a hospital that records 800 deaths per year (not necessarily all within the hospital per se but including bodies delivered to the hospital), with the average length of time that a body remains in the mortuary being 8 days and with a body tray occupancy rate of 80%.
BT = (D x S) / (365 x R) = (800 x 8) / (365 x 0.8) = 6400 / 292 = 21.92

With body cabinets generally having a storage capacity of three bodies per cabinet the calculated required capacity should be rounded up to the nearest multiple of three and as such in the above example 8 cabinets would be required.

The estimated storage capacity for bodies in a mortuary could be confounded by a number of local factors, such as:

  • Mortality rate from natural causes.
  • Mortality rate from infectious disease.(Highly contagious disease deaths require special storage facilities.)


Where the hospital is expected to place the body in cold storage until collection by forensic pathology services, the following additional factors should be considered with respect to numbers of unnatural deaths (accidental, suicidal, homicidal, unknown and procedure-related deaths) anticipated at any particular hospital, including:

  • Mortality rate from foul play (homicide) or suicide
  • Mortality rate from traffic or other accidents
  • Mortality rate from procedure-related deaths
  • Mortality rates from sudden, unexpected or unexplained deaths

Selecting Body-Storage Systems

Body-storage systems are principally divided into refrigerated rooms or body cabinets. Differences within these system types occur where specific temperatures or sizes are required based on risk, need and capacity requirements. Body cabinets should be arranged such that the lowest shelf would have sufficient capacity for the heaviest bodies.
Where a system of functionally separate body cabinets is selected, this system would have an inherent redundancy against failure, as the failure of a single unit would not necessarily imply a system failure. In contrast, a refrigerated room would require less maintenance and would have a lower frequency of failure; however, a single component failure could be critical if standby condensing units are not installed. For this reason,multiple-cabinet systems are recommended for areas where expected maintenance response times would negatively affect the mortuary’s operations.
It is possible to have a requirement for a mixture of refrigerated rooms and body cabinets. This could be affected by local cultural requirements such as for families who object to bodies sharing storage space, the caseload of the facility or the case profile.
Where there is a requirement for the long-term storage of bodies, these are to be kept at a lower temperature than would be the case in a refrigerated room. In this instance, separate body cabinets are required. Long-term storage of bodies is most often required when an indigent person dies and difficulty is experienced in locating the next of kin, as the person cannot legally be buried until this process has been completed.
In general, smaller facilities rely on body cabinets for the storage as these facilities do not have the space or the need for the large-scale storage of bodies, they would not appreciate the functional flexibility offered by these systems. By rule of thumb, any facility that has the requirement to store fewer than 12 bodies at any given time should use body cabinets. This gives the option of providing both short- and long-term storage with the smallest facility and equipment footprint.
Bodies suspected of having succumbed to a highly contagious and dangerous disease require special treatment. These should be stored in such a manner that they do not present a hazard to personnel working in the mortuary. Typically these bodies should be stored at the same temperature as long-stay bodies,e.g.-20°C, and should be placed in hermetically sealed plastic body-bags.
Provision for the secure cold storage of body parts should be provided.

Facility Layout

As mentioned, the layout and size of a mortuary are going to be largely determined by caseload and whether storage is in cabinets or refrigerated rooms. It is acceptable to have a mixture of refrigerated rooms and body cabinets.
In a mortuary facility, there are a number of separate areas that need to be considered other than the body-storage areas. These include:

  1. Reception area for members of the public who are required to visit the mortuary on official business – typically to identify bodies or to pay their last respects to a deceased person.
  2. Ablution areas for staff. Where unisex ablutions are provided it is recommended that no urinal is provided.
  3. Visitors’ admin space close to the reception area, where any admin or official business related to the identifying of a body can be completed.
  4. Staff admin space close to the point where a body is delivered to the mortuary so that pertinent documentation can be completed – both with respect to the delivery of the body, as well as when the body is released from the mortuary again.
  5. Office space for pathologists to write up reports in instances where this could be required. This is dependent on the size of the mortuary as small facilities would not require a separate room(s) for this function.
  6. Waiting and circulation areas for visitors to the mortuary.
  7. Viewing room, from where a body can be viewed through a curtained glass window between this space and the body-display room.
  8. Body-display room, where a body is placed for identification purposes. There is to be access to this area via a lockable door to the viewing room in instances where it is necessary for non-mortuary personnel to have direct access to a body in the viewing room. There is to be access to this room from the body-storage area to allow bodies to be brought in for display purposes.
  9. Body preparation area, where a body that is delivered to the mortuary needs to be attended to prior to it being placed in the viewing room.
  10. Shower facilities (staff)
  11. Changing room (staff)
  12. Storage space for equipment and clothing that is worn in the body-preparation and autopsy spaces.
  13. Body-storage facility (cold room or refrigerated cabinets), depending on the length of time that bodies are expected to be kept in the facility.
  14. Autopsy facility, where the cause of death can be determined. This facility will differ from mortuary to mortuary, depending on whether forensic pathology service or standard medical autopsies to determine the cause of death are conducted.
  15. The image below is an example of an adjacency diagram for a typical mortuary. In this instance, the proximity also relates to visual and physical access. It is also understood that not all mortuaries would require all of the spaces indicated in this diagram and that some of the spaces shown as being immediately adjacent could be included as a single area should functionality and privacy considerations permit it.
    Mortuaries Adjacency Diagram
  16. There remains abundant scope for variations in the planning of the layouts making up the mortuary. The hospital architect should consult with all stakeholders to arrive at an ideal solution.
  17. When developing the facility layout, careful consideration should be given to the routes through the facility of staff, bodies and visitors. These routes should overlap as little as possible and there should never be a common entrance for bodies and staff or visitors.
  18. The room requirement sheets are presented in USER ROOM REQUIREMENTS of this document.
  19. Storage space for body lifts must be provided.
  20. Suitable sluicing facilities are required to be able to clean equipment and fabrics after completion of any work in the mortuary facility.

Mortuary Equipment Requirements

1. Equipment for storage and transportation of bodies should meet environmental hygiene standards. 2. For mortuary trolley design and supply,the SABS published standard CKS336:2013 Mortuary Trolleys is recommended.It should be noted that this is not a normative South African National Standard,and individual requirements may differ. a. Body-cabinet selection and installation requires the following considerations: b. Three-level body cabinets could be selected which have a single door to give access to all of the body trays,for instances where separation between bodies is required.Alternatively,cabinets that provide a single door for access to all the body trays are acceptable. c. It is critical that bariatric (obese) bodies are catered for in each cabinet.The lowest-level tray should be designed for this purpose. d. Special consideration is to be given to the provision of capacity for storage of juvenile and infant decedents.The handling of these bodies is an especially sensitive and emotive issue,and separate storage in dedicated cabinets is recommended. e. Body lifts must be supplied to facilitate the loading of bodies into and removal of bodies from the cabinets.Body lifts help to preserve dignity when handling bodies,while at the same time making it easier and safer for mortuary personnel to handle bodies. f. A clear space must be provided in front of the body cabinets to allow for the placing of a corpse into the cabinets.It is recommended that there be at least a 3m clearance between the front of the cabinet and any fixed structure.This is to accommodate whatever means of conveyance is used to transport a corpse to the storage area and then load it into the cabinet. g. Due to the vast array of cabinets available on the market and the lack of an appropriate national standard,it is not yet possible to prescribe sizes for refrigerated cabinets in this guide. h. The required cabinet size is fundamental when designing a mortuary.Where space is not too limited and there are no indications that there may be cultural concerns relating to the storage of bodies together in a cold room,it is recommended that cold rooms be used.Cold rooms offer space savings when compared to cabinets. i. A temperature gauge must be installed close to the door of the facility to indicate the storage-space temperature.This gauge should have an alarm system connected to it to give a warning should there be an unacceptable rise in temperature in the storage space.Typically,if the temperature should rise more than 2?C above the set temperature,an alarm should be activated at a point that is manned at all times. j. Body cabinets and refrigerated rooms must be supplied with electrical power from the hospital’s essential services electrical supply. k. A slop hopper is to be provided to allow for the cleaning of the body preparation and autopsy areas,in particular after the completion of any work carried out in these areas. l. To allow for the rinsing of body parts and organs,during an autopsy procedure it is important that suitable basins be provided in close proximity to a downdraft autopsy table. m. Where there is transition between “clean” and “dirty” areas,provision is to be made to allow for the cleaning of footwear in a “transitional” area.This helps prevent the transport of contaminants from dirty areas.
