What should handhole enclosure covers have to identify their function?

Handhole enclosure covers need to have an identifying mark or logo to clearly indicate their function. This is crucial for maintenance and safety, as it allows personnel to quickly recognize the purpose of the enclosure without needing to open it or examine it closely. Depending on the industry, these marks or logos can signify electrical, telecommunications, or other utilities, helping prevent errors during inspection or repair work.

While specific colors, numerical codes, or technical drawings may provide useful information in some contexts, having a clear identifying mark or logo is the most effective way to ensure that anyone working with the enclosure can quickly and accurately discern its function. This reduces the risk of accidents or miscommunication regarding the enclosure's contents and purpose.
