Under this option, products made, in whole or in part, of PUF that contains TCEP and intended for children under three years of age are prohibited from manufacture, advertisement, and sale in and importation into Canada. Children under the age of three are the focus of this prohibition as a result of the Screening Assessment Report identifying this subgroup as the most highly exposed population. The frequent mouthing behaviour children in this age range are known to exhibit increases the likelihood they will be exposed to TCEP and its potentially harmful effects. The same level of risk as a result of dermal and inhalation exposure to TCEP was not identified in the Screening Assessment Report.
