Lab No Entry Without Teacher

This prohibition sign reads NO ENTRY INTO LABORATORY – WITHOUT A TEACHER PRESENT, with Dilarang Masuk Ke Makmal – Tanpa Kehadiran Guru in Bahasa Malaysia. A Chinese version (无教师在场禁止进入实验室) is available. The crossed-out figure makes the message clear even to younger students. It belongs on the door of every makmal sains, makmal komputer, bengkel kemahiran hidup and living-skills room in SK, SMK and SJK schools, as well as college and matriculation laboratories throughout Malaysia. Many schools pair it with the full Science Laboratory Rules sign inside the room. Choose a sticker to apply straight onto the lab door or the glass panel beside it, PP hollow board for a low-cost rigid sign, or PVC foam board for a smarter, durable panel. Sizes from A6 to A1 and five language versions. Every sign is printed to order and delivered nationwide.
