What 化学製品製造オペレーター do

An English description is being prepared. Japanese description:

化学工場で各種装置を運転・制御して合成樹脂、化学肥料、化学繊維、洗剤、塗料などの化学製品を製造する。プラントオペレーターとも呼ばれる。(医薬品、化粧品等製造オペレーターについては「医薬品製造」「化粧品製造」を参照。)
 製品は日夜連続して生産され、なかには何年も連続で稼動する装置もある。また、運転員の担当は、「計器室担当」と「屋外担当」の大きく2つに分かれる。
 「計器室担当」は、中央制御室でコントロールパネルを監視し、さまざまな装置や機械の運転・操作をする。
 例えば、原料を製造装置に投入し、加熱、冷却、撹拌する機械を操作したり、ポリエチレン、塩化ビニールなどの樹脂を製造するために、押出装置を操作して粒状化する。製造した化学薬品を充填する機械の運転・監視もする。製造工程で異常な事態が生じた時は、マニュアルに則して原料の供給や温度、圧力などを操作し、化学反応をコントロールする。
 一方、「屋外担当」は、大型の装置など屋外のパトロール業務が中心となる。装置の稼動状況を確認し、異常の早期発見に努めるとともに、運転条件の各種変更に伴う機器の切り替えや、トラブル発生の際には、「計器室担当」と緊密に連携をとりながら対処することが求められる。また、数年に一度の定期的な点検・修理の際には、装置を止め、配管を1本ずつ確認しながらプラント内の可燃物を除く作業を行う。工事や配管等の交換が必要な場合は立ち会う。点検作業が終了後、プラントを再稼働するが、原料を一から投入し直したり、機械などに不具合がないか確認しながら行う。これらの作業を生産の遅れにならないように、一定の期間に終了しなければならない。

How AI is changing this job

A written analysis for this occupation is being prepared.

AI replacement risk compares the parts of a job that are easy to hand to AI or software (processing information, documentation, repetitive computer work) with the parts that are hard to automate (physical work, working closely with people, judgment in unpredictable settings), using the MHLW job tag survey on work activities, work context, skills and knowledge. The result is a relative position among all occupations in the country, scaled to 0–100%. Methodology →
