Description

  The present invention relates to a dangerous place display device, and more particularly to a marking device for notifying a dangerous place such as a road to the surroundings to promote warning and danger avoidance.

  It has been a problem that residents and fire brigade members have fallen into fire protection tanks during fire fighting and injured. Each fire department is also looking for measures to recognize the importance of fall prevention measures and to take safety measures.

  As an attempt to prevent the fall, for example, it is a common practice to install a road cone around a manhole or a fire protection water tank which is opened by removing a lid to prompt a warning. However, such an aspect does not cover the open area but causes a gap, so that it is insufficient as a fall prevention treatment, and another countermeasure has been desired.

  As another countermeasure as described above, it has been conventionally proposed to install a drop prevention ladder at an open portion or to cover a drop prevention lid. However, the proposal of such a fall preventing ladder and a fall preventing lid has been a problem in terms of the complexity of handling and the cost aspect, and has not reached widespread use until now.

  The present applicant has the concept of transportability, storability, and ease of installation under the idea that it can not provide a marking device excellent in identification of the open area and reliable noticeability and visibility to the surroundings as a fall prevention treatment. We have developed a sign body that is excellent in the ease of handling, and lead to the proposal of the "danger spot sign body" according to the present invention.
