Stop and escalate
For an unknown substance, damaged package, leak, reaction, vapour, heat or fire, isolate the area and follow the product-specific emergency plan. Do not clean up without competent direction.
Know what is present
- Maintain an approved inventory with product identity, classification, quantity, package size, location and responsible owner.
- Keep current safety data sheets accessible to workers and emergency responders.
- Verify labels at receipt and quarantine unidentified, damaged or leaking packages.
- Track maximum approved quantities by room, zone and storage class.
Segregate by compatibility
- Use the competent site assessment and applicable rules to define separation, cabinets, bunding and dedicated zones.
- Do not assume products are compatible because they share a hazard symbol or supplier.
- Protect packages from heat, sunlight, moisture, impact and unauthorised access as required.
- Keep drains, escape routes, fire equipment and electrical panels clear.
Control handling and emergencies
- Define approved equipment, PPE, decanting limits and ignition controls for each task.
- Provide spill materials suited to the substances present; generic absorbent may be unsuitable for some products.
- Train people to raise the alarm, isolate the area and use the product-specific emergency information.
- Report exposure, loss of containment, damaged packaging and inventory differences immediately.
Compliance evidence
- Approved inventory and location plan.
- Safety data sheet register and review dates.
- Receipt inspections, storage inspections, training and emergency exercises.
- Waste transfer or disposal evidence and closed corrective actions.
Questions for the supervisor review
- Can the team produce a current location-and-quantity inventory during an emergency?
- Are compatibility decisions supported by approved information?
- What happens when a package arrives without a readable label or current safety data sheet?
- Can waste and returned material be traced to authorised disposal or return?
Useful measures
Use your own verified history and risk profile rather than a generic target. Review these measures together:
- Unidentified or damaged packages
- Quantity-limit and location exceptions
- Safety-data-sheet gaps
- Spills, exposures and overdue corrective actions
Turn the review into action
Record the exact location, observation, immediate control, risk, accountable owner, due date and closure evidence. Review repeated or overdue issues with management and the competent specialist for the subject.

Original field application
Work the problem from evidence to closure
Practice situation
A new chemical SKU arrives before its approved storage location has been confirmed. The useful response is not a generic target or a tick-box answer. Start by defining the exact event, location, item, time period and decision owner so that another reviewer can reproduce what happened.
Decision path
Stop putaway, identify the substance from its label and safety data, then obtain competent advice on segregation and controls. Record assumptions before changing the process. Compare the proposed control with the current condition, test it on a limited scope where appropriate, and define the condition that would require work to stop or management to escalate.
Evidence pack
Safety data sheet, inventory, compatibility decision, approved location, inspection and emergency information. Keep the source record with the action rather than copying only a summary into a presentation. A complete pack should show who reviewed the information, what was excluded, the date of the decision and proof that the action was later checked.
Supervisor walkthrough
- Observe the work at the location and ask the operator to explain the normal sequence.
- Compare the observed sequence with the written standard and system record.
- Separate an isolated exception from a repeated condition by checking recent history.
- Agree one immediate control and one corrective action with a named owner and realistic date.
- Return after implementation and verify the result with evidence, not verbal confirmation.
Common failure to avoid
Do not close the review with “team advised” or “monitor closely.” Those statements do not identify a changed control, accountable owner or effectiveness check. A useful closure states what changed, where it changed, when it was checked and what result would reopen the issue.
