The Team That Didn't Hand Over
A laboratory runs two shifts. On Friday, the morning technician, Sophie, prepares a batch of diluted bleach solution for surface disinfection. She labels it 'Bleach - made Friday' and leaves it on the bench. The afternoon technician, Ravi, assumes it is fresh and uses it to wipe down benches and equipment. On Monday morning, a third technician, Amir, finds the same bottle still on the bench and uses it again. No one checks the concentration or the date. Meanwhile, a new casual staff member, Jess, has been asked to prepare a chemical solution she has never made before; she asks Ravi for help, but he is busy and says 'just follow the sheet'. The sheet is a photocopy with a step missing. Jess proceeds anyway and the solution turns out weaker than required.
1. Analyse the communication and documentation failures in this scenario.
Read the worked answer
Failures:
- Inadequate labelling - 'Bleach - made Friday' lacks the date, concentration, preparer's name, and expiry. Diluted bleach loses potency over time, so a Friday batch used on Monday may be ineffective.
- No handover - Sophie did not tell Ravi the bottle's age or status. Ravi assumed freshness; Amir assumed the same. Assumptions replaced communication.
- No verification step - neither Ravi nor Amir checked concentration or date before use. A simple check would have caught the problem.
- Inadequate supervision and induction - Jess was given an unfamiliar task with a defective procedure and no proper support. 'Just follow the sheet' is not training, especially when the sheet is incomplete.
- Poor document control - a photocopied procedure with a missing step should not be in use. Procedures must be current, complete, and controlled.
Underlying theme: The laboratory relies on informal assumptions rather than explicit, recorded communication.
2. What should each person have done differently?
Read the worked answer
Sophie: Label the bottle fully - chemical name, concentration, date and time prepared, preparer, expiry. Tell Ravi at handover what was made and when. Store it appropriately.
Ravi: At the start of his shift, check the labelling and age of any prepared solutions. If the bottle was made Friday and it is now Friday afternoon, it may still be usable, but he should confirm the required concentration and the expiry. He should not assume. He should also make time to support Jess, or direct her to someone who can - 'just follow the sheet' is not an acceptable answer for an unfamiliar task.
Amir: On Monday, the bleach is three days old. He should check the label and the laboratory's rule on bleach shelf life (often 24 hours for diluted bleach). If in doubt, make fresh solution and discard the old.
Jess: She was right to ask for help. When the answer was inadequate, she should have escalated - to the supervisor or another experienced staff member - and refused to proceed with an incomplete procedure. She should also report the defective sheet.
3. Propose improvements to the laboratory's systems to prevent recurrence.
Read the worked answer
Systems improvements:
- Standardised labelling - a template requiring name, concentration, date/time, preparer, expiry, and hazard symbols. Provide labels at the preparation bench.
- Written handover - a shift handover sheet or log recording prepared solutions, equipment status, and outstanding issues. Both shifts sign.
- Shelf-life rules - a clear, displayed rule for unstable preparations such as diluted bleach, with a discard-by date on the label.
- Document control - procedures must be current, complete, version-controlled, and reviewed. Photocopies with missing steps must be withdrawn.
- Induction and competency - new staff should not perform unfamiliar preparations unsupervised until competency is demonstrated and recorded.
- Speak-up culture - staff should feel able to escalate when a procedure is incomplete or support is unavailable, without fear of blame.
- Regular review - audit labelling and handover compliance periodically, and discuss findings at team meetings.
