Signal words indicate acute toxicity categories used on U.S. EPA labels. Use them as a hazard cue before handling or application planning.
Highest acute toxicity category. Treat this product as high hazard and follow strict PPE, handling, and exposure controls from the label.
Moderate acute toxicity category. Careful handling and label-level protections are still required for safe use.
Lower acute toxicity category relative to Danger/Warning, but it still requires full label directions and local rules.
Signal word communicates hazard severity, not permission to use. Always follow the full product label, PPE requirements, and local/state regulations.
This EPA source record is marked cancelled. Confirm whether a current replacement or allowed label record should be used before you continue.
Once the EPA record, product label, and local requirements line up, continue in SprayLedger to capture a complete application record with traceable history and export later.
