Strong Sensitizer: CPSC Revising ‘Strong Sensitizer’ Definition

This news update on Strong Sensitizers is brought to you by OHS Online.



Among the hazards the law addresses are substances that are toxic, corrosive, flammable, combustible, or are strong sensitizers. Since 1961, the regulation listed five substances, including formaldehyde.


Since 1986, the U.S. Consumer Product Safety Commission has defined a “strong sensitizer” is a substance that causes an allergic response, meaning an irritant would not meet that definition; in addition, substances that produce a sensitivity reaction solely because of someone’s first exposure can be classified as strong sensitizers. CPSC is now moving to change the definition.


The new definition defines criteria for “severity of reaction” and also provides for the use of a weight-of-evidence approach to decide whether a substance is a strong sensitizer.
