Special Hazardous Substances

1.  For our school's laboratory waste disposal operations, in accordance with the campus waste management plan and environmental regulations reported in 2008 (97th year), waste management must include the submission of 'Waste Management Codes' to facilitate proper classification and storage, and to reduce the risk of hazards.
2. Laboratory waste liquids generated at various locations can be categorized into the following seven types:

• C-0201: Waste liquid with a pH value greater than or equal to 12.5
• C-0202: Waste liquid with a pH value less than or equal to 2.0
• C-0119: Other mixed waste containing toxic heavy metals that exceed leaching standard
• C-0299: Other corrosive industrial waste mixture
• C-0149: Other mixed waste containing organochlorine pollutants that exceed leaching standards

• C-0399: Other flammable industrial waste mixtures (with a flash point below 60°C)
• D-2399: General waste chemical mixtures (with a flash point above 60°C)

Please select the code(s) that correspond to the components of the laboratory waste liquid to facilitate proper classification and storage during disposal.
