Blackboard'un öğretim sürecinde öğretmenlerin ellerine kaçınılmaz olarak tebeşir tozu bulaşacaktır. Aynı zamanda havada yüzen parçacıklar da öğretmenin saçına, yüzüne ve boynuna düşerek cilt zarını tahriş eder. Alkali maddeler üretmek için yazın ter tarafından hidrolize edilirse, cildi ve mukoza zarlarını daha da tahriş eder, çünkü insan derisinin ortamı, cildin temel yaşam ortamını yok eden zayıf asidik bir ortamdır. Toz alkali bir etkiye sahiptir ve tebeşir tozu cildi kuru ve pürüzlü hale getirir, buna kaşıntı eşlik eder ve bu da insan vücudunu rahatsız eder. Şiddetli vakalarda akne, folikülit, piyoderma, çatlamış cilt ve öğretmenlerin normal iş ve yaşamlarını etkileyen ve engelleyen yoğun saç dökülmesine neden olabilir.
