The nursery manager learned about putting warning signs on traffic cones during a class on Reentry Intervals (REI).
Remember, pick up the cones when the REI is over. Workers may start to ignore warning signs if they are left out.
Setup & use
- Attach adhesive warning signs to orange traffic cones.
- Place cones along the edge of treated areas before applying pesticides. Locations include: entry corners points; roads & pathways; edges within 100 feet of worker housing.
- Ensure that at least two cones are visible at any point along the edge of the treated area.
- Pick up cones promptly after the REI is over.
- Orange traffic cones (28”H)
- Lime traffic cones (28”H)
- Adhesive vinyl WPS warning signs that comply with EPA regulations (16”H x 14”W)
- Select traffic cones for the durability and stability. Sport cones are too lightweight.
- Use lime green cones for other temporary hazards like potholes and broken irrigation pipes.
- Use pole stands and hand carts for moving and storing stacked cones.
- Attach a pole stand to application equipment or a farm vehicle to transport stacked cones to the field.
