01 / Categories of liquid lab wastes

Liquid wastes are the unavoidable byproduct of many laboratory processes, whether from clinical medical tests & procedures or laboratory research & experimentation. Thus, liquid lab waste disposal is of particular interest to the EPA, besides as to many statewide agencies, many of which accept stricter regulations than their federal counterparts.

For the purposes of this discussion, liquid lab waste matter is separated into ii categories:

02 /Listed and Feature liquid lab wastes

There are 2 kinds of chancy chemical waste co-ordinate to the EPA: Listed and Characteristic.

Listed wastes. The EPA maintains 2 lists of substances that it considers hazardous waste, called the "P" and "U" lists. (Hence, "listed wastes.") The primary departure between the 2 is their level of risk. Stated succinctly, U-listed wastes are "toxic," significant they can impairment an organism to 1 caste or another; and P-listed ones are even more unsafe.

Characteristic wastes. Wastes that don't announced on the U or P lists might nonetheless be deemed hazardous waste product for their "characteristics." (Hence, "characteristic wastes.") There are four characteristics, three of which are adequately self-explanatory: ignitability, corrosivity, and toxicity.

The fourth—reactivity—is a bit more complicated. It's the tendency of one substance to become ignitable, corrosive, or toxic in the presence of another, pregnant that if you dispose of both into a mutual container, they become a hazardous waste, even though each is benign lone.

E.m. mixing an acrid and so mild that we sprinkle information technology on a salad—vinegar—with something every bit relatively benign as household bleach—Clorox®—volition generate highly toxic chlorine gas.

Also consider: mixing different chemical wastes that are already hazardous past themselves tin can form a compound that's even more than corrosive, ignitable, reactive, and/or toxic than any 1 of its constituents, so even more than dangerous.

E.g., obviously water in the presence of sodium hydride or alkali metals (such as sodium or potassium), will generate flammable hydrogen gas. Or mixing it with sodium phosphide will yield highly toxic phosphine gas.

So, as in all things involving hazardous waste product disposal, it's crucial to get expert advice.

03 /You demand a plan for separating laboratory chemical wastes

Given that certain laboratory chemic wastes are reactive when combined, it's crucial that you continue them separated.

Thereby, you cannot allow individual employees to be making ad hoc decisions about what to do with a random chemical lab waste when it presents itself. You need a arrangement: the prosaic place for everything and everything in its place.

One time you've developed such a system—and ensure anybody'due south trained about it—it'south much less likely that dangerous or potentially litigious mistakes will exist made.

Likewise, when liquid wastes are properly separated and safely stored, your workplace operations will be inherently safer—and less likely to run afoul of OSHA rules.

04 /Guidelines for handling laboratory chemical wastes

Use containers that won't dethrone with exposure to sunlight or the chemical itself.

Keep all chemical wastes separated. Don't accept untrained staff making advert hoc decisions about which might be compatible with the other.

Designate & label storage areas where food, flammables, and other specific substances should not be introduced.

Label storage containers with important information, such equally when received, opened, tested, etc.

Continue an inventory of in-house chemical wastes awaiting hazardous waste disposal.

05 /Biological and "RMW" laboratory liquid wastes

Unlike from being Listed or Feature, a laboratory liquid waste tin can be "hazardous" for existence a "biological waste material" or "regulated medical waste product" (RMW). These are liquid wastes that are infectious, radioactive, or otherwise unsafe, including but not express to:

Anything that'due south been soaked in blood (gloves, gauze, gowns, etc.)

Cultures of infectious diseases and/or agents

Regulated medical waste product (RMW) presents a number of compliance challenges considering most rules governing it are divers at the country level. Adding to the complication, rules for medical waste disposal often emanate from multiple state agencies.

Nigh all states have enacted medical waste product regulations, just standards vary widely. Some state medical waste disposal rules are fashioned after the Medical Waste Tracking Deed, while others carry footling resemblance.

"In most states, the environmental protection agency is primarily responsible for developing and enforcing regulations for medical waste management and disposal. Although in some states, the department of health may play an important function (e.g., MO, OK) or even serve every bit the primary regulatory agency (e.g., CO). Where both agencies are involved, typically the department of wellness is responsible for onsite management and the environmental agency is responsible for transportation and disposal (eastward.g., LA, MO)."

06 /Biological and "RMW" laboratory liquid wastes

Once your wastes are properly identified, categorized, and separated, you must ensure that they're transported to the correct category of waste disposal facility. Due east.g., in that location are chemical wastes vs. biological wastes vs. corrosive wastes vs. reactive wastes, etc.

Different companies are "permitted" to transport each. Unlike facilities are "permitted" to receive them for treatment and/or disposal. And the onus is entirely upon you to cull amongst them correctly.

Also bear in listen that because of your EPA "cradle-to-grave" responsibilities for any hazardous waste you generate, the legal consequences for engaging a legally-unqualified supplier is entirely upon yous.
