Hazardous substance
Ethylene dibromide
REPORTABLE QUANTITY1.0 lb
EQUIVALENT0.454 kg
What this means
Federal rules list Ethylene dibromide as a hazardous substance, with the reporting threshold — called the reportable quantity, or RQ — shown above. If this much (or more) is spilled or released, it has to be reported to authorities. For regular chemicals and waste codes, that threshold is measured in pounds and kilograms. Knowing the RQ is one piece of hazmat compliance, not the whole picture — you'll still need to confirm the proper shipping name, packaging, and labeling separately.
