DQE developed the Sentry Shield line of personal protective kits to protect police officers and first responders from white powdery substances that could contain fentanyl, carfentanil, or other powerful opioid-based substances. The Sentry Shield kits are configured based on the recommendations of the National Institutes of Occupational Safety & Health (NIOSH) and the US Drug Enforcement Administration (DEA). These personal protection kits range in coverage based on the severity of exposure levels responders may encounter.
