4.     Have fly ash containerization and storage before disposal.

12    Health & Safety (Protective Gear)    1.     Staff handling waste must be well trained on safe handling of hazardous wastes
2    Feeding And Charging    Controlled hygienic, mechanical or automatic feeding methods have to be used which won’t influence the air temperature in the primary and secondary chambers of the incinerator negatively.

No waste is to be fed into the incinerator:

1.     Until the minimum temperatures have been reached.
All pollutant concentrations must be expressed at Oo C and 1.013 x 10 5 N/m2, dry gas and 11% oxygen correction.

Oxygen correction is computed as:

Es =     21 — Os    x EM

OM    = measured oxygen concentration

10    Operation    1.     Materials destined for incineration should be of known origin and makeup and must be only incinerated in a furnace that’s registered for the specific type of waste.

2.     A record must be kept of the amount, type and origin of the waste to be incinerated.
3.     The addition of dilution air after combustion in order to reach the requirement of these guidelines is unacceptable. The minimum exit velocity should be 10 m/s and at least twice the surrounding wind speed (Efflux velocity = wind speed x 2) whichever is greater to make sure no down washing of exiting gases.

5.     Point for the measurement of emissions shall be provided.

7    Instrumentation    Instrument for determining the interior wall temperature rather than burner flame temperature has to be provided for both primary and secondary chambers.

4.      Fire fighting equipment must be provided
5.     The incinerator must be in good working order at all times and must not be used if any part fails. Any malfunction ought to be recorded in a log book and reported to the relevant authority.
