Standards
For Incinerators
All incinerators shall meet the following operating and emission
standards:
A. Operating
standards
1. Combustion
efficiency (CE) shall be at least 99.00 %.
2. The combustion efficiency is

Note:
-
Suitably

with the incinerator
to achieve the above emission limits, if necessary.
-
Wastes
to be incinerated shall not be chemically treated with any chlorinated
disinfectants.
-
Toxic
metals in the incineration ash shall be limited within the regulatory
quantities as defined under
the Hazardous waste (Management and Handling) Rules, 1989.
-
Only
low sulphur fuel like LDO/LSHS/Diesel shall be used as fuel in the
incinerator
Standards
For Waste Autoclaving
The autoclave
should be dedicated for the purpose of disinfecting and treating biomedical
waste.
1. When
operating a gravity flow autoclave, medical waste shall be subjected
to:
i. A
temperature of not less than 121 oC and pressure of 15
pounds per square inch (psi) for
an autoclave residence time of not less than 60
minutes; or
ii. A
temperature of not less than 135 oC and a pressure of 31
psi for an autoclave residence time
of not less than 45 minutes; or
iii. A
temperature of not less than 149 oC and a pressure of 52
psi for an autoclave residence time of
not less than 30 minutes.
2.
When operating a vacuum autoclave, medical waste shall be subjected
to a minimum of one
per vacuum pulse to purge the autoclave of all air. The
waste shall be subjected to the following
i. A
temperature of not less than 121 oC and a pressure of 15
psi per an autoclave residence time
of not less than 45 minutes; or
ii. A
temperature of not less than 135 oC and a pressure of 31
psi for an autoclave residence time
of not less than 30 minutes; or
3. Medical
waste shall not be considered properly treated unless the time, temperature
and pressure
indicators indicate that the required time, temperature
and pressure were reached during the autoclave
process. If for any reasons, time, temperature
or pressure indicator indicates that the
required temperature, pressure or residence time was not
reached, the entire lead of medical waste
must be autoclaved again until the proper temperature,
pressure and residence time were achieved.
4. Recording
of operational parameters.
Each
autoclave shall have graphic or computer recording devices which will
automatically and
continuously monitor and record dates, time of day, lead
identification number and operating
parameters through out the entire length of the autoclave
cycle.
5. Validation
test:
Spore
testing: The autoclave should completely and consistently kill the
approved biological indicator
at the maximum capacity of each autoclave unit. Biological
indicator for autoclave shall be Bacillus
stearothermophilus spores using vials or spore strips,
with at least 1*104 spores per million. Under
no circumstances will an autoclave have minimum operating
parameters less than a residence time of
30 minutes, regardless of temperature and pressure, a
temperature less than 121 oC or a pressure less
than 15 psi.
6. Routine
tests
A
chemical indicator strip/tape that changes colour when a certain temperature
is reached can be used
to verify that a specific temperature has been achieved.
It may be necessary to use more than one
strip over the waste package at different location to
ensure that the inner content of the package has
been adequately autoclaved.
Standard
For Liquid Waste
The effluent
generated from the hospital confirm to the following:
|
Parameter |
Permissible limit |
| pH |
6.5
– 9.0 |
| Suspended
solids |
100
mg/l |
| Oil
and grease |
10
mg/l |
| BOD |
30
mg/l |
| COD |
250
mg/l |
| Bioassay
test |
90%
survival of fish after
96
hours in 100% effluent |
These limits are
applicable to those hospitals which are either connected with sewers
without terminal
sewage treatment plant or not connected to public sewers with terminal
facilities, the general standards
as notified under the Environment (Protection) Act, 1986 shall be
applicable.
Standards
Of Micro waving
1. Microwave treatment shall not be used for cytotoxic, hazardous
or radioactive wastes, contaminated
animal carcasses, body parts and large metal items.
2.
The microwave system shall comply with the efficacy tests/routine
tests and a performance guarantee
may be provided by the supplier before operation of the
unit.
3.
The microwave should completely and consistently kill bacteria and
other pathogenic organism that is
ensured by the approved biological indicator at the maximum
design capacity of each microwave unit.
Biological indicators for microwave shall be Bacillus
Subtilis spores using vials or spore strips with a
least 1*104 spores per millilitre.
Standards
For Deep Burial
1. A pit or trench should be dug about 2 m deep. It should
be half filled with waste, then covered with
lime within 50 cm of the surface, before filling
the rest of the pit with soil.
2. It
must be ensured that animals do not have access to burial sites. Covers
of galvanised iron/wire
meshes may be used.
3. On
each occasion, when wastes are added to the pit, a layer of 10cm of
soil be added to cover the
wastes.
4. Burial
must be performed under close and dedicated supervision.
5. The
deep burial site should be relatively impermeable and no shallow well
should be close
to the site.
6. The
pits should be distant from habitation, and sited so as to ensure
that no contamination occurs
of any surface water or ground water. The area should
not be prone to flooding or erosion.
7. The location of the deep burial site will be authorised
by the prescribed authority.
8. The
institution shall maintain a record of all pits for deep burial.
