1.     OBJECTIVE OF THE PROGRAMME

 

The objective of the programme is to select technical criteria suitable for tender specification purposes that will enable the South African Department of Health to obtain the services and equipment necessary for the primary health care clinics to carry out small-scale incineration for the disposal of medical waste.

 

2.     STRUCTURE OF THE PROGRAMME

 

The test programme is being carried out in phases, as follows:

Phase 1         A scoping study to decide the responsibility of the different parties and

consensus on the test criteria and boundaries of the laboratory tests. The criteria for accepting an incinerator on trial was approved by all parties involved.

Phase 2         Laboratory tests with a ranking of each incinerator and the selection of the incinerators to be used in the field trials.

Phase 3         Completion of field trials, to assess the effectiveness of each incinerator under field conditions.

Phase 4         Preparation of a tender specification and recommendations to the DoH for the implementation of an ongoing incineration programme.

 

This document provides feedback on phases 2 and 3 of the work.

5.3.   Emission testing: laboratory method

 

Sampling of emissions followed the US-EPA Method 5G dilution tunnel method for stove emissions. Adjustments to the design were made to account for flames extending up to 0.5 m above the tip of the incinerator and the drop out of large pieces of ash. Emissions were extracted into a duct for isokinetic sampling of particulate emissions. The sampling arrangement is shown by a schematic in Figure 1. A photograph of the operation over the Molope gas fired incinerator unit is shown in Figure 2.

 

All tests were performed according to specified operating procedures. The instructions provided by the supplier of the equipment were followed in the case of the C&S Marketing Unit. No operating procedures were supplied with the Molope Gas, Molope auto-combustion and PaHuOy units. These procedures were established by the CSIR personnel using their previous experience together with information provided by the supplier.

 

Test facilities were set up at the CSIR and measurements were carried out under an ISO9001 system using standard EPA test procedures or modifications made at the CSIR.

5.6.   MAIN FINDINGS OF THE LABORATORY TRIALS

 

The main conclusions drawn from the trials are as follows:

 

:::          All four units can be used to render medical waste non-infectious, and to destroy syringes or render needles unsuitable for reuse.

:::                           The largest potential health hazard arises from the emissions of smoke and soot.              (the combustion efficiency of all units lies outside the

regulatory standards). The risk to health can be reduced by training operators to avoid the smoke or by installation of a chimney at the site.

:::          The emissions from small scale incinerators are expected to be lower than those from a wood fire, but higher than a conventional fire-brick-

lined multi-chambered incinerator.

:::          Incomplete combustion, and the substantial formation of smoke at low height rendered the PaHuOy unit unacceptable for field trials. Figure 3

below shows this unit during a trial burn. Molten plastic flowed out of

the incinerator, blocked the primary combustion air feed vents, and burnt outside of the unit.

5.7.   COMPARISON OF THE FIELDS TRIALS WITH THE LABORATORY TRIALS

 

The CSIR performed a quantitative trial in the field for gas combustion efficiency, temperature profiles and mass destruction rate on the Molope Auto wood-fired unit at the Mogale Clinic.

 

The results of this trial are compared to the laboratory trial results below:

 

• Waste loading: Disposable rubber gloves were observed in addition to needles syringes, glass vials, bandages, dressings, and paper w
• Temperatures and combustion efficiency: The same performance in gas combustion        efficiency   was    obtained    for    wood    .

Temperatures were higher but for a shorter time and this was

correlated with the type of wood available to the clinic. The fuel was burnt out before the medical waste was destroyed completely and this resulted in lower temperatures, lower combustion efficiency and higher emissions while burning the waste.

• Emissions: Large amounts of black smoke were observed and this was correlated directly to cooling of the unit as the wood fuel was exhausted

prior to full ignition of the waste.

• Destruction efficiency: The destruction efficiency was similar to that in the laboratory measurem
• Usability: The unit is difficult to control as the result of the variability of the quality of wood
• Acceptability: the smoke was not acceptable to the clinic, the community, or the local

 

It was concluded that:

• The performance with fuel alone indicates that laboratory trial data can be used to predict emissions in the
• The Molope Auto unit is too difficult to control for the available staff and fuel at the

 

 

 

5.8.   RECOMMENDATIONS FROM THE LABORATORY TRIALS

 

The following recommendations are made as the result of the laboratory trials:

:::     A comprehensive operating manual must be supplied with each unit.

Adequate training in the operation of the units must be provided, especially focussed on safety issues.

:::     It is recommended that the height of the exhaust vent on all units be

addressed.     In order to facilitate the dispersion of emissions and reduce the exposure risk of the operators.

:::     The suppliers of the incinerators must provide instructions for the safe handling and disposal of ash.

 

 

 

5.9.   RECOMMENDATIONS FROM THE STEERING COMMITTEE

 

 

 

After completion of the laboratory trials, the project steering committee recommended that the Molope Gas and C&S Marketing units be submitted for field testing. The Molope Auto was recommended for field testing on the condition that the manufacturer modified the ash grate so as to prevent the spillage of partially burnt needles and syringes.

 

 

 

6.     FIELD TRIALS

 

6.1.   OBJECTIVE OF THE FIELD TRIALS

 

The objective of the field trials was to obtain information in the field and assess the strengths and weaknesses of each of the incinerators during use at primary health care clinics.

 

A participative decision making process was used for the trials. It was based on expert technical evaluation by the CSIR and the National Department of Health as well as participation in the trials by experienced end users and participating advisors. All decisions were made by the Steering Committee, which consisted of representatives of stakeholders in the clinical and medical waste disposal process. These included representatives from the National, Provincial, and Local Government departments of Health, Safety and the Environment, as well as Professional Associations, Unions, NGOs, UNICEF, the WHO and local community representatives.

6.3.   COORDINATION OF THE TRIALS

 

The criteria for the ranking of the incinerators in accordance with performance in the field were:

 

• Safety (occupational and public health)
• Destruction capability
• Usability
• Community acceptability

 

The South African National Department of Health coordinated the field trials.

 

Information regarding the field trials as well as questionnaires were supplied to the coordinators in the participating provinces.

 

The team in the field consisted of the operator, supervisor and inspector (coordinator). The manufacturer of the incinerators did the training of the operators.

 

The questionnaires used during the trials were set so as to obtain information with regard to the criteria set for the ranking of the incinerators in accordance with performance in the field. The questionnaires were received from the clinics at two-weekly intervals.

 

Questions with regard to the criteria were the following:

 

A.  SAFETY (occupational and public health)

 

• Smoke Emission

y Volume and thickness

y Colour

y Odour

• Ash Content
• Are the filled sharps boxes and soiled dressings stored in a locked location while waiting to be incinerated?

 

 

 

B.  DESTRUCTION CAPABILITY

 

• Destruction Rate

y Complete

y Partial

y Minimal

y Residue content

 

C.  USABILITY (for the available staff)

• Can the incinerator be used easily?

 

 

• Is the process of incineration safe?
• Has training been successful?
• Is protective clothing such as gloves, goggles, dust masks and safety boots available?

 

D.  COMMUNITY ACCEPTABILITY

 

• What is the opinion of the following persons on the use of the incinerator?

y Operator
