Label-free real-time techniques provide the kinetics of the cytotoxic response rather than just a snapshot like many colorimetric endpoint assays. Material that has been determined as cytotoxic, typically biomedical waste, is often marked with a symbol that consists of a capital letter "C" inside a triangle. [7] [8]
Hazard pictograms form part of the international Globally Harmonized System of Classification and Labelling of Chemicals (GHS). Two sets of pictograms are included within the GHS: one for the labelling of containers and for workplace hazard warnings, and a second for use during the transport of dangerous goods.
Hazard symbols may vary in color, background, borders, or accompanying text to indicate specific dangers and levels of risk, such as toxicity classes. These symbols provide a quick, universally understandable visual warning that transcends language barriers, making them more effective than text-based warnings in many situations.
Biomedical waste should be collected in containers that are leak-proof and sufficiently strong to prevent breakage during handling. Containers of biomedical waste are marked with a biohazard symbol. The container, marking, and labels are often red. Discarded sharps are usually collected in specialized boxes, often called needle boxes.

The previous hazard symbols for chemicals, were introduced in the Directive Directive 67/548/EEC, in 1967, and required to be adopted no later than 1 January 1970. [6] The symbols were also included as a part of Directive 1999/45/EC. [7] The symbols were replaced from 1 December 2010 to 1 June 2017, via a gradual phaseout. [1]
“Water waste reduction is an important thing too,” said Drew. “There are a lot of old homes or condos that have leaks.” Converting to smarter homes is one way to capitalize on technology ...
