Environmental & Spill Control

Back to all safety programs

Overview

Spills can reach soil, drains and waterways in minutes; the goal is to prevent them and respond fast and correctly.

Prevention uses containment, storage and SDS; response follows STOP–CONTAIN–CLEAN-UP–REPORT with spill kits on hand.

Prevention

Secondary containment / bunds at least 110% of the largest tank.
Drip trays under taps, pumps, generators and transfer points.
Store chemicals and fuels away from drains and watercourses.
Keep an SDS on file for every substance and label all containers.

Step-by-step spill response

STOP the source — close the valve or stop the transfer if safe.
Raise the alarm, put on the correct PPE and check the SDS.
CONTAIN — block drains and surround the spill with booms and pads.
Never wash the spill toward storm drains or waterways.
CLEAN-UP — recover the liquid and soak up residue.
Bag and label used absorbents and contaminated soil as hazardous waste.
REPORT internally and notify authorities at reportable quantities.
Restock the spill kit and review the cause to prevent recurrence.

Waste management

Segregate waste into general, recyclable and hazardous streams.
Dispose of hazardous waste only via a licensed contractor, with a manifest.
Keep spill kits stocked near every storage and transfer point.

Roles & responsibilities

Role	Responsibility
Worker	Stops the source, gives first response and reports immediately.
Supervisor	Directs the clean-up, controls the area and escalates as needed.
HSE / Environmental Officer	Handles waste disposal, statutory reporting and the investigation.

Common mistakes to avoid

Hosing a spill into a storm drain to make the area look clean.
Storing drums with no bund or containment near a drain.
Mixing hazardous with general waste, or using an unlicensed disposer.

Frequently asked questions

What is Environmental & Spill Control?

Spills of fuel, oil, chemicals and waste can contaminate soil, block or pollute drains and reach waterways within minutes. On an engineering site the goal is twofold — prevent spills through good storage and containment, and respond fast and correctly when one does happen.

Who is responsible?

Worker: Stops the source, makes the first response and reports the spill immediately.; Supervisor: Directs the clean-up, controls the area and escalates as needed.; HSE / Environmental Officer: Handles waste disposal, statutory reporting and investigates the cause.

What are the most common mistakes to avoid?

Hosing a spill into a storm drain to make the area look clean. Storing drums with no bund or containment near a drain. Mixing hazardous waste with general waste, or using an unlicensed disposer.
