![]() ![]() Solid chemical wastes are usually disposed of in landfills or incinerated. Waste disposal may be either land disposal or incineration. A combination of treatment options may be required to meet site-specific regulatory requirements and protect human health and the environment.ĭisposal refers to the final resting place of hazardous waste after all possible treatments have been applied. The choice of a treatment method depends on the characteristics of the hazardous wastes being treated, as well as site-specific considerations. Specifically, these methods include physical/chemical treatment such as thermal treatment (incineration), chemical treatment (acid/alkaline hydrolysis), and biological treatment. Treatment methods for laboratory hazardous wastes can be divided into two broad categories: environmentally acceptable or technologically enhanced methodologies. Next, identify the type of waste and store them separately in labeled containers for future disposal and treatment. The first step is to segregate hazardous waste from other wastes. Handling hazardous laboratory waste involves professionals who can carry out all these processes. Gases such as methane, hydrogen sulfide, and carbon monoxide are all examples of gas-based laboratory waste products. Gaseous hazardous waste contains toxic gases that pose a risk to humans because they can irritate the eyes, nose, and throat or cause headaches and nausea. They may include thinners, solvents, and stains. These wastes must be neutralized before being disposed of otherwise, they could cause burns or create an explosive environment. Liquid hazardous waste includes chemical solutions containing acids or bases, organic solvents, and water from chemical reactions. It can be placed in plastic bags and stored as-is, as long as the area it's being stored in is properly ventilated. Solid hazardous waste includes infectious or pathological wastes, culture dishes, discarded chemical reagents, and glassware. Laboratory hazardous waste must be segregated into three categories: solid, liquid, and gaseous. Most countries have developed their hazard codes based on ASTM standards to comply with their regulatory bodies. The outcome of this process is a set of characteristics or properties of the waste called its "hazardous waste code" or "identifier." The most widely used hazard codes are produced by the American Society for Testing and Materials (ASTM), but other systems are also used worldwide. Waste characterization is performed by industrial hygienists, safety professionals, waste generators, or regulators and involves determining whether a waste is ignitable, corrosive, toxic, or reactive. Waste characterization is a waste management process that identifies the health and environmental risks of each waste stream and classifies them to determine the appropriate disposal method to minimize risks to workers, communities, and ecosystems. Laboratory Hazardous Waste characterization Record-keeping and reporting requirements.Īs a general rule of thumb, laboratory hazardous waste management is an activity that requires regular involvement by the principal investigator (PI) to ensure compliance with relevant regulations. ![]() ![]() Treatment and disposal of hazardous wastes and.Storage of wastes containing one or more hazardous components.Separation of hazardous from non-hazardous wastes.Proper characterization of wastes to determine their hazards.These wastes are usually complex, toxic, and potentially dangerous to human health and the environment if not managed properly. The activity focuses on handling specific wastes generated from laboratory experiments and research. Laboratory Hazardous Waste Management is more complex than ordinary waste management.
