BASIC INDUSTRIAL "Keep Door Closed" Safety Sign (Cambodian/Khmer) 270 x 420 mm, Thickness 3 mm

BASIC INDUSTRIAL "Keep Door Closed" Sign (Cambodian) Size 270 x 420 mm, Thickness 3 mm
The BASIC INDUSTRIAL "Keep Door Closed" sign is made from 3 mm thick plastwood. It is a mandatory sign used to establish guidelines for orderliness and safety within buildings. The sign conveys its message clearly with an open door symbol accompanied by an arrow indicating the closing direction inside a blue circular background, which is an international standard symbol indicating that passersby must shut the door completely every time. Installing this sign is primarily intended to help save energy consumed by air conditioning systems, prevent dust, insects, or disease-carrying pests from entering, and restrict access to unauthorized areas for security purposes. The plastwood material is lightweight and moisture-resistant, allowing for convenient installation on control room doors, cold room doors, or main building entrances.

Features
- Made of 3 mm thick plastwood sheet, lightweight, with clean straight edges; does not rust or corrode from general moisture exposure.
- Uses the standard blue color for mandatory signs and large text that is clearly visible at eye level, ensuring that passersby promptly comply with regulations.
​​​​​​​- The door and closing arrow symbol inside a blue circle is an internationally recognized icon that is immediately understood, minimizing miscommunication.
​​​​​​​- Features a smooth surface that can be easily wiped clean of dust or stains with a damp cloth.
​​​​​​​- Easy to install on smooth surfaces using heavy-duty double-sided tape on the back, or by drilling holes to secure with screws onto door panels, concrete walls, or glass walls.

Applications
​​​​​​​- Laboratories, cleanrooms, or research facilities where dust levels and air pressure must be strictly controlled.
​​​​​​​- Cold storage rooms, frozen warehouses, or temperature-controlled storage facilities to prevent outside heat from disrupting the cooling environment.
​​​​​​​- Office buildings, meeting rooms, or server rooms to help reduce air conditioning workload and save on electricity costs.
- Building entrances/exits, factory doors, or fire escape routes to prevent unauthorized entry and maintain round-the-clock security.
