Labeling of Chemicals

There are few greater potential hazards around the laboratory than that of unmarked or improperly labeled chemicals. All chemicals must have complete identification securely fastened to the container. Chemicals of unknown stability and those which deteriorate with age shall have a preparation date clearly indicated on the label. Disposal of unlabeled bottles is dangerous and therefore very expensive and tightly regulated by law.

Required information on labels includes:

	The name of the material
	An appropriate hazard warning
	The target organ effect

Labels are displayed for the life of the container:

	Labels are not to be removed or defaced when received or in use
	Check to insure that labels are legible and affixed
	Make sure the label information is current
	If the label is destroyed, immediately mark the container with required information

Portable containers into which hazardous chemicals are transferred from labeled containers and intended for immediate use must be labeled with the product name.

Information concerning the hazards associated with a chemical can be obtained quickly from a notation developed by the National Fire Protection Association (NFPA). This notation uses a diamond shaped symbol which is subdivided into four square segments.

In addition, special precaution symbols may be used where necessary. The following are special precaution symbols which may be found in addition to the NFPA chemical hazard diamond.

Other additional safety information that may be located on a chemical label includes:
