Acid Etching Precautions
酸液蚀刻防护要点
标签：安全,通风橱,耐酸防护,废酸中和,皮肤冲洗
所有酸蚀在通风橱进行，穿戴耐酸围裙、手套、护目镜与防毒面具；皮肤接触立即用大量清水冲洗并就医。废酸须中和（如小苏打）至 pH 6–8 后按危废处置，禁止直接倒入下水道。
Do all acid etching in a fume hood with acid apron, gloves, goggles and respirator; flush skin contact with copious water and seek care. Neutralize waste acid (e.g., with baking soda) to pH 6–8 before hazardous disposal—never pour down the drain. ---
