Dalam proses pengajaran Papan Hitam, guru pasti akan mendapat habuk kapur di tangan mereka. Pada masa yang sama, zarah yang terapung di udara juga akan jatuh pada rambut, muka dan leher guru sehingga merengsakan selaput kulit. Jika ia dihidrolisiskan oleh peluh pada musim panas untuk menghasilkan bahan beralkali, ia akan merengsakan kulit dan membran mukus lebih banyak lagi, kerana persekitaran kulit manusia adalah persekitaran berasid yang lemah, yang memusnahkan persekitaran hidup asas kulit. Habuk mempunyai kesan alkali, dan habuk kapur menjadikan kulit kering dan kasar, disertai dengan gatal-gatal, yang menjadikan tubuh manusia tidak selesa. Dalam kes yang teruk, ia boleh menyebabkan jerawat, folikulitis, pyoderma, kulit pecah-pecah dan keguguran rambut secara besar-besaran, yang menjejaskan dan mengganggu kerja dan kehidupan biasa guru.
