Standard Test Methods for Screening of Reactive Sulfides in Waste

Significance and Use

5.1 These test methods are intended for use by waste treatment, storage, disposal, and remedial facilities, in order to show the presence of potentially hazardous sulfide.

5.2 Method B: Gas Detector Tube—This proposed test method was designed to measure gases migrating into an air space at a height of 10 units (for example, 10 ft) from a receiving or mixing pit of 10 units square (for example, 100 ft2). In essence, the total volume of the atmosphere is approximately 10 times the surface area of the sample and test solution.

Scope

1.1 These test methods are applicable to the screening of reactive sulfides in wastes, liquids, sludges, semisolids, and solids by using the following methods:

 

Sections

  Test Method A—Lead Acetate Paper

9 – 14

  Test Method B—Gas Detector Tube

15 – 19

1.2 These test methods are not applicable in determining the type and concentration of reactive sulfides.

1.3 These test methods are designed and intended as a preliminary test to complement the more sophisticated quantitative analytical techniques that may be used to determine sulfide concentration. These test methods offer, to the user, the option and the ability to screen waste for potentially hazardous levels of reactive sulfide when the sophisticated techniques are not available and the total waste composition is unknown.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific hazard information is given in Section 7 and 11.3.
