formaldehyde solutions shipped by highway only do not require classification as a hazardous material.) Guidance for shipping these solutions are provided in Paragraphs 2 and 4 of this Fact Sheet. • 10% Formalin solutions contain 3-4% Formaldehyde and are not regulated for transport by air or highway.
Formaldehyde fixatives | The Microscopy Alliance | The A fixative labeled as 10% buffered formalin is actually only a 4% solution of formaldehyde. This is because 10% buffered formalin is an example of old-time histologist's jargon describing a 10% solution made from a stock bottle of 37-40% formaldehyde (or more precisely: a 3.7-4% solution of formaldehyde) .

10% neutral buffered formalin is a general histological tissue fixative. Contains formaldehyde buffered to a neutral pH. DETAILS Use: Required for tissue/specimen fixation. For laboratory use only. Hazards: contains paraformaldehyde, chemical known to cause cancer. Handling: with care. Warning! Harmful if swallowed, inhaled or absorbed to skin. Formaldehyde- Safe Work Practices formaldehyde solution is classified as a Category 4 flammable liquid with a flashpoint of 64 °C (147 °F). Formaldehyde becomes a fire or explosion hazard in the presence of heat, flames or other sources of ignition. Upon ignition, the chemical decomposes into carbon oxides (i.e. carbon monoxide, carbon dioxide), which can be hazardous to humans.

This mixture of formaldehyde in isotonic saline was widely used for routine histopathology prior to the introduction of phosphate buffered formalin. It often produces formalin pigment. 4.
