Environmental Properties

Vertrel® has zero ozone-depletion potential. It is used extensively to replace CFC-113, methyl chloroform, hydrochlorofluorocarbons (HCFCs), and perfluorocarbons (PFCs) in several applications.

Vertrel® SMT has been accepted by the U.S. Environmental Protection Agency (EPA) under the Significant New Alternatives Policy (SNAP) program, as a substitute for ozone-depleting substances. The methanol component of Vertrel® SMT is considered a hazardous air pollutant (HAP) and, therefore, subject to NESHAP regulations. Methanol is included in the SARA Title III Section 313 list of toxic chemicals, and is subject to SARA Title III (EPCRA) reporting requirements.

The components of Vertrel® SMT are listed in the TSCA inventory. One component, HFC-43-10mee, is subject to the Significant New Use Rule (SNUR) and should be used only in the applications indicated in the Vertrel® SMT Safety Data Sheet regulatory section.

Flammability and Toxicity

Vertrel® SMT exhibits no closed-cup flash point in accordance with the Pensky-Martens Closed Cup Tester (ASTM D-93) and is not classified as a flammable liquid by NFPA or DOT. However, the product does exhibit vapor flammability limits in air. Users should clear equipment of all vapors and liquids before performing any maintenance operations that may result in an ignition source.

Flash point data and limits of flammability in air provide the user with additional information that should be used as elements of a fire risk assessment and to determine guidelines for safe handling of volatile chemicals. Users should ensure compliance with NFPA standards and local fire codes.

Acute toxicity studies show that Vertrel® SMT has low toxicity. It could pose a slight skin and eye irritation and has low inhalation toxicity. For exposure limits please refer to the Vertrel® SMT brochure.
