Safe Handling of 10% Neutral Buffered Formalin
What is Formalin? Formalin is diluted Formaldehyde. It is a hazardous chemical. It is a colorless gas with a pungent odor. It is most often used in aqueous solutions for preserving specimens. It can be irritating to the skin if exposed; it can be irritating to the respiratory tract if inhaled. It can be carcinogenic if exposed to large quantities.
Storage Formalin containers are obtained from the main laboratory. Formalin may be found on bronchoscopy carts. Formalin containers must be stored in a locked closet, in an upright position (to prevent leaks).
