No processo de ensino do Blackboard, os professores inevitavelmente sujarão as mãos com pó de giz. Ao mesmo tempo, partículas flutuando no ar também cairão no cabelo, rosto e pescoço do professor, irritando a membrana da pele. Se for hidrolisado pelo suor no verão para produzir substâncias alcalinas, irritará ainda mais a pele e as mucosas, porque o ambiente da pele humana é um ambiente fracamente ácido, que destrói o ambiente básico de vida da pele. A poeira tem efeito alcalino, e a poeira do giz torna a pele seca e áspera, acompanhada de coceira, que incomoda o corpo humano. Em casos graves, pode causar acne, foliculite, pioderma, pele rachada e queda de cabelo maciça, que afeta e interfere no trabalho e na vida normal dos professores.
