A pesticide handler was preparing to apply pesticides in a greenhouse room. He posted the large warning sign on the door. Then an employee entered and claimed that he did not see the sign. Since the signs have covered the door handle, no one has entered a posted restricted area.
Remember to remove the warning sign each time after the REI ends. People may start to ignore signs, if they are left up after the REI.
Setup & use
- Use the full size (14" width x 16" height) warning sign.
- Cut a slot in the warning sign just big enough to slip over the fixed staple.
- Install the fixed staple to the door.
- Slip the sign over the staple and insert the linchpin.
- Warning sign (16" H x 14" W), stiff and waterproof
- Fixed staple with screws
- Center the slot horizontally.
- Place the staple and linchpin where they don’t obscure the words or images.
- Store the linchpin in the staple to be ready for next time.
- Use a lock in place of a linchpin for outside doors.
