You will need

- - list the components of the waste;
- tables and calculations to determine hazard class.

To deliver the waste to the class of

**risk**by using the calculation method, find the rate (K) is a measure of the degree**of hazard***of the waste*for OPS (the natural environment). If the waste consists of several substances, calculate its score as the sum of indicators**of risk**of these substances (Ki). So first of all install:a) a list of components*of waste*(composition);b) the quantitative content of each component.As a rule, the composition*of waste*is determined by the composition of the feedstock, given the changes happening with him in the process, or on the basis of chemical analysis results.2

*Now calculate the indicator of the degree*

**of hazard**of each

*waste*according to the formula: Ki = Ci/Wi (Ci - concentration of component

*waste*, and Wi - the coefficient of the degree

**of danger**for OPS). For the determination of coefficient (Wi) in the Order of the Ministry of Natural resources "On approval of criteria for classification of hazardous waste to the class of

**hazard**for the natural environment" dated 15.06.2001 of the year there is a special table (see drawing).

If you have a degree

**of danger**components*of waste*in any natural environments, with their help it is possible to calculate the relative parameter**risk**component*of the waste*to CV (Xi). This is done by dividing the sum of scores of all parameters on the number of these parameters. The coefficient Wi can be calculated by one of several formulas (reference: http://www.ecology.ru/uploads/image006.gif).4

*The coefficients (Wi) view in the table (see picture). Here are the most common components of waste that can be dangerous for OPS.*

Once you have calculated the exponents

**of the danger**of the individual components*of the waste*Ki, calculate the index K as a sum of individual components (K=K1+K2+...+Kn).6

*Now calculate the class*

**of danger**

*of waste*on the natural environment in accordance with the table (see picture). If the waste falls into the fifth class

**of danger**should confirm his experimental method. Otherwise, you will have to qualify the class

**of danger**as 4th.

To determine the class

**of danger**of the pilot by contact specially accredited for these purposes, the lab.
