칠판을 가르치는 과정에서 선생님들은 필연적으로 손에 분필가루가 묻을 것입니다. 동시에 공기 중에 떠다니는 입자도 선생님의 머리카락, 얼굴, 목에 떨어져 피부막을 자극합니다. 여름에 땀에 의해 가수분해되어 알칼리성 물질을 생성하게 되면 인간의 피부 환경은 약산성 환경이기 때문에 피부와 점막에 더욱 자극을 주어 피부의 기본적인 생활 환경을 파괴합니다. 먼지는 알칼리 작용을 하고, 분필가루는 피부를 건조하고 거칠게 하고 가려움증을 동반하여 인체를 불편하게 한다. 심할 경우 여드름, 모낭염, 농피증, 갈라진 피부, 대량 탈모 등을 유발하여 교사의 정상적인 업무와 생활에 영향을 미치고 방해가 됩니다.
