A tar pusher is a laborer who works in road mending, roofing, or some other field that consists of placing asphalt or tar on a horizontal surface. ==Qualifications== A tar pusher is a physically and mentally taxing occupation. Thus, there are a some criteria that must be met in order to be considered even a novice tar pusher, and to be safe: * Medium to heavy build: This is rather important because the worker is, indeed, pushing tar. Tar is a very dense material and its viscosity is very high, making it difficult to push or move. * Stamina to withstand the long hours of repetitious and tedious tasks that are associated with tar pushing. * Sufficient knowledge of the materials being used, considering tar is a very dangerous substance. Different techniques should also be learned in order to work at one's best. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tar pusher」の詳細全文を読む スポンサード リンク
