Identify hazardous or special waste, maintain containment and labels, protect drains and respond to releases through the emergency environmental plan.
Boundary

Only trained and equipped people should respond to significant or unknown releases, classify waste or arrange regulated transport.
Application
How to reason through a site scenario
Identify the material if safe, protect people and drains, contain within training and escalate using the environmental emergency procedure.
Risk pitfalls and guardrails
washing a spill into a drain
Guardrail: Do not convert a remembered assessment answer into permission to perform a safety-critical practical task.
using an unlabelled container
Guardrail: Do not convert a remembered assessment answer into permission to perform a safety-critical practical task.
handling a substance without suitable PPE and information
Guardrail: Do not treat protective equipment as a substitute for elimination, isolation, collective protection or competent planning.
Memory anchors
First spill priorities?
Raise the alarm, stop the source if safe, contain and protect drains, then report through the site plan.
Why label hazardous waste?
So hazards, compatibility and lawful handling remain clear through storage and transfer.
May a spill be diluted into a drain?
No. Prevent pollution and use the approved containment and disposal route.
Unknown waste found?
Do not open, mix or move it casually; isolate the area and obtain competent identification.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
