What information should be included on de-icing fluid label warnings?

Including health warnings and environmental impact information on de-icing fluid label warnings is crucial for safety and environmental protection. De-icing fluids often contain chemicals that can pose health risks if inhaled or if they come into contact with skin. By providing health warnings, users are informed of potential hazards and can take appropriate precautions when handling or applying the fluid.

Moreover, the environmental impact information is vital as de-icing agents can affect waterways and ecosystems. Providing details about the environmental effects of the ingredients helps users make informed decisions about the use and disposal of the fluid, promoting safer environmental practices.

The other options, while they offer certain information, do not address the critical safety and environmental considerations that are essential in handling de-icing fluids. Price and volume information, for example, may be relevant for purchasing decisions but does not assist in ensuring safe usage. Manufacturer's history and origin and details about color and consistency may be interesting but do not pertain to health risks or ecological impact, making them less relevant for de-icing fluid labels.
