Q

PUBLIC HEALTH ENGINEERING?

A
  • DEFINED AS THE ART AND SCIENE OF PREVENTING DISEASE, PROLONGING LIFE AND PROMOTING HEALTH THROUGH THE ORGANISED EFFORT OF SOCIETY
  • HUMANITARIAN CONTEXTS ARE CREATED WHEN AN EVENT OR SERIES OF EVENTS REPRESENTS A CRITICAL THREAT TO THE HEALTH, SAFETY, SECURITY OR WELLBEING OF A COMMUNITY OR OTHER LARGE GROUP OF PEOPLE, USUALLY OVER A WIDE AREA (EVENTS SUCH AS ARMED CONFLICTS, EPIDEMICS, FAMINE, NATURAL DISASTERS
  • PUBLIC HEALTH ENGINEERING IN THE HUMANITARIAN CONTEXT WORKS TO REDUCE EXPOSURE TO HEALTH RISKS IN A BID TO REDUCE MORBIDITY AND MORTALITY

Q

WATER SUPPLY IN A HUMANITARIAN CONTEXT - COLLECTION AND HOUSEHOLD STORAGE

A 
Collection and household 
storage
•Distribute containers
•Minimum storage capacity 
of 40 l/ household.
•Containers should have a 
small opening for pouring 
out water rather than 
large openings that allow 
for dipping to avoid 
contamination.
- Locally made materials (e.g. clay containers) can 
be used.
•Regular cleaning and 
disinfection of containers 
should be encouraged.

Q

WATER SUPPLY IN A HUMANITARIAN CONTEXT - PUBLIC WATER DELIVERY POINT

A 
Public water delivery point
•Should not exceed 100m 
distance.
•Planned to allow at least 
200-250 persons per tap.
•Good flow at minimum 10 
litres/minute/tap
•Hand pump wells should 
serve 500-750 persons 
per pump
•the design and 
construction must be 
sturdier than used in 
similar domestic 
connections.

Q

SANITATION PECULIARITIES IN A HUMANITARIAN SETTING (what is permitted in a humanitarian setting but wouldn’t be permitted in a non humanitarian setting)

A
  • Plastic bags are sometimes provided in acute situations. Advocacy
    on appropriate use should be provided.

• Defaecation field or controlled open defecation is designed as 0.5
m2/user/day.

• 1 improved trench latrine/100 users. (trench latrine: communal toilet option widely-used in emergencies)

• The recommendation is to provide family latrine closed to each dwelling (place of residence) or on a row not too far from general dwelling area. Each
family can padlock theirs.

• If this is not possible, the alternative is to construct one latrine per
lot of three or four dwellings (or about 20 people). It is called a
cluster latrine.

• The same number of bathing facilities as toilets per 50 persons (short-term) or 20 persons (long-term) should be provided for communities

Q

SOLID WASTE MANAGEMENT IN A HUMANITARIAN SETTING - HOUSEHOLD LEVEL VS COLLECTIVE

A

• Household-level management strategy should focus on education
and enlightenment.

Q

CATEGORIES OF MEDICAL WASTE

A
  • INFECTIOUS WASTE
  • RADIOACTIVE MATERIALS
  • PHARMACEUTICAL WASTE
  • CHEMICAL WASTE
  • GAS CONTAINERS
  • TOXIC SUBSTANCES
  • SHARP MATERIALS
  • HUMAN ORGANS
17
Q

THE MINIMUM THREE BIN METHOD TO COLLECT AND SEGREGATE MEDICAL WASTE

A

CATEGORIES:

1) GENERAL WASTE/NOT HAZARDOUS (E.G. PAPER); CONTAINER COLOUR/LABEL: BLACK
2) USED SHARPS/HAZARDOUS, INFECTIOUS (E.G. NEEDLES, INFUSION SETS, BROKEN GLASS..); CONTAINER COLOUR/LABEL: YELLOW, LABELLED ‘SHARPS’, LEAK-PROOF AND PUNCTURE PROOF
3) NOT SHARPS/ HAZARDOUS, INFECTIOUS (E.G. MATERIALS CONTAMINATED WITH BODILY FLUIDS, SUCH AS SWABS, DRESSINGS, LABORATORY CULTURES..); CONTAINER COLOR/LABEL: YELLOW, LABELLED AND LEAK-PROOF

18
Q

DESCRIBE VECTOR CONTROL THROUGH ENVIRONMENTAL CONTROL

A

Environmental Control:

Site selection and planning: Good location to reduce risk of exposure.

Water management: Avoid creation of breeding sites and removal of existing breeding sites.

Safe excreta disposal: Reduce the opportunities of insect vectors breeding on excreta dumps.

Waste Management: To avoid creating a breeding site/transmission site for vectors.

General Construction: Inclusion of insect screens, sealing of openings under doors, and use rodent baffles in drainpipes in buildings.

Removal of Vegetation: Cleaner environment. Mowing or even controlled burning of vegetation in the vicinity of buildings help control mites and ticks.

19
Q

DESCRIBE VECTOR CONTROL THROUGH PERSONAL PROTECTION

A

Personal hygiene and behaviour: Reduces risk of disease transmission by flies or lice.

Protection by clothing Increasing the thickness of clothing and the area of skin covered can reduce risk to insect bites. Clothing can also be
impregnated by appropriate insecticide/repellent.

Repellents: Can be natural or chemical to protect against insects. Chemical lasts longer but must be used appropriately.

Coils: Vapours from coils are quick and easy way to neutralise insects in rooms or enclosed areas. Does not require electricity.

Electric vaporiser systems: Requires electrical heating device to evaporate an insecticide from a base which is often refillable.

Aerosols: Often used in enclosed areas to kill flying or crawling insect. Those for flying insect killers have approximately 20 minutes
effective period while. Crawling Insect killers can last between 4 to 12 weeks before re-appearance of insects.

Long Lasting Insecticidal Nets (LN): Insecticide treated nets are one of the most effective ways of controlling malaria. They are also easy to distribute to the
populace/use in humanitarian settings. They can also be used to isolate an already infected person from further transmission.

Other insecticide-treated materials: Examples are blankets, curtains and other shelter materials.

20
Q

DESCRIBE VECTOR CONTROL THROUGH CHEMICAL CONTROL

A

Insecticide Residual Spraying (IRS): Widely used for control of mosquitoes, triatomine bugs and sandflies. It is applied to the surfaces inside a tent or house. The susceptibility of local vectors, duration of the residual effect in relation with the length
of the transmission season should be verified and considered.

Insecticide zooprophylaxis: Could be used here vectors bite domestic animals as well as humans. It is applied to the air and skin of domestic livestock using a sponge or
animal dip.

Insecticidal dusting: It consists of talcum powder, or another inert carrier powder mixed
with insecticides. Can be applied on rodent footpaths and habitats or
dusting people against lice.

Rodenticides: It should be a slow acting poison to reduce rats and mice related
health risks. Should be accompanied with health promotional
activities.

Larvicide: It is complex, requires expertise but highly effective. It is applied in
low concentrations to vector breeding sites (larva sites) that have
been mapped

21
Q

ROLES OF AID ORGANISATIONS IN DISPOSAL OF DEAD BODIES

A

Provision of morgues in health facilities

Cemetery or cremation sites

Provision of shrouds and /or transport

Provision of leak proof body bags, blanket, mats, clothes and coffins (in acute emergencies or where families cannot afford to provide them)

Provision of protective clothing for those coming in contact with the dead bodies

22
Q

DESCRIBE PROVISION OF MORGUES IN HEALTH FACILITIES IN HUMANITARIAN CONTEXT

A
  • 20 BED HEALTH FACILITY SHOULD PROVIDE SPACE FOR 2 DEAD BODIES
     Windows should be avoided.
     Vents should be protected from rodent’s entry.
     Floor should be smooth concrete with a 1% slope towards drain.
     Masonry tables should be avoid placing bodies on the floor.
     Privacy screens or curtains should be provided for relatives.
     Water point should be close to the morgue for body disinfection and washing.

27
Q

T-SHELTER?

A

THE TERM CAN MEAN EITHER:
- TEMPORARY SHELTER
- TRANSITIONAL SHELTER
(THE DEFINITIONS OF THE 2 OVERLAP WHICH CAN PROVIDE FLEXIBILITY WHEN THE TERMS TEMPORARY OR TRANSITIONAL ARE POLITICALLY UNACCEPTABLE)

28
Q

TYPES OF SHELTERS?

A

EMERGENCY - SHORT TERM

TEMPORARY - IN SOME LOCATIONS SUCH AS CAMPS WHERE THERE IS NO PLANNED END STATE, SHELTERS CANNOT BE ‘TRANSITIONAL’, AND TEMPORARY SHELTER MUST HAVE A LONG DURATION (CAN BE REMOVED AT A CERTAIN POINT)

TRANSITIONAL - an incremental process which supports the shelter of families affected by conflicts and disasters, as they seek to maintain alternative options for their recovery (SHELTERS WHICH ARE PHYSICALLY PERMANENT BUT PEOPLE USE THEM FOR A LIMITED AMOUNT OF TIME BEFORE SETTLING SOMEWHERE ELSE)

PROGRESSIVE - IN SOME COUNTRIES, THE TERMINOLOGY ‘TRANSITIONAL SHELTER’ MAY BECOME UNACCEPTABLE, ESPECIALLY WHERE RECONSTRUCTION ON A PERMANENT SITE IS POSSIBLE; THESE SHELTERS CAN BE CALLED PROGRESSIVE SHELTERS

CORE/PERMANENT HOUSING - IN SOME LOCATIONS IT IS POSSIBLE TO BUILD PERMANENT STRUCTURES (PERMANENT HOUSING), BUT FOR REASONS INCLUDING BUDGETS, EQUITY AND SPEED IT IS DECIDED TO BUILD ONLY A PART OF A FINAL HOUSE (CORE)
