Share your requirementsWho usually fills this role
Usually ITI, diploma or B.Sc. holders, many promoted from helpers. Test at hiring with reading a process instruction, unit conversion and safety knowledge. Ask what they would do for a temperature rise, leak or power cut. Look for discipline with steps and PPE.
Skills ladder
Stage 1
New joiner
- Wears PPE and follows the batch instruction
- Charges materials by weight under supervision
- Records temperature, pressure and time
Stage 2
Independent
- Runs reactor steps and takes samples as per the instruction
- Responds to alarms by procedure
- Cleans equipment and completes records
Stage 3
Senior or lead
- Handles critical steps and troubleshooting
- Leads shift operations and reports deviations
- Trains operators on safety and process
Training path
First weeks
- 1
Chemical safety
The safety officer explains hazards, PPE, spill and emergency response for the block. The joiner demonstrates PPE and emergency actions.
- 2
Process instruction
The supervisor goes through the batch instruction and each critical step. The joiner repeats the steps and explains why.
- 3
Equipment basics
A senior shows reactor, valves, condensers and instruments. The joiner identifies parts and lines.
First year
- 1
Supervised batches
The operator works with a senior on full batches. The chemist reviews records and discusses deviations.
- 2
Emergency drills
The safety officer runs drills for leaks and fire. The operator performs roles and gets feedback.
- 3
Records and sampling
QC shows sampling and recording. The operator's entries are checked by QA.
Towards senior
- 1
Critical steps
The supervisor allows the operator to lead critical steps like addition rate control. Reviews follow.
- 2
Troubleshooting
The chemist shows causes of temperature or yield variation. The operator solves a mock case.
- 3
Training
The operator coaches juniors using the instruction. The supervisor checks results.
Performance review
Daily feedback from the supervisor, a monthly review of records, deviations and safety observations, and a written half-yearly review. Keep brief written notes of each review.
What to measure
| Measure | How it is seen |
|---|---|
| Following the instruction | Record audit and observation |
| Safety behaviour | Observation and near-miss reports |
| Accuracy of readings and charging | Weigh and reading checks |
| Response to alarms | Incident reviews |
| Cleaning and equipment care | Cleaning records |
| Deviation reporting | Deviation log |
Evidence to bring
- Batch records
- Near-miss reports
- Drill records
- Cleaning records
- Training sign-offs
Questions to ask in the review
- Which step in the process worries you?
- Did any alarm or leak happen? What did you do?
- What PPE is missing or uncomfortable?
- What makes batches vary?
- What records are hard to fill?
- How does the shift handover go?
- What would you like to learn?
- What can the chemists explain better?
Pitfalls
- Skipping drills because production is busy
- Treating a leak as the operator's failure
- Not training on why steps matter
- Rotating staff between blocks without hazard briefing
