What's in a Spill Kit? (Oil vs Chemical vs Universal)

A standard spill kit contains: sorbent pads, sorbent socks/booms, a sorbent roll (cut-to-size), heavy-duty disposal bags and ties, gloves, goggles, and a laminated spill response instruction card. Chemical kits also include compatible PPE and neutralising agents. The sorbent colour (white = oil-only; grey = universal; yellow = chemical) is the fastest visual indicator of kit type.

Spill kits are not all the same. The contents vary significantly between oil-only, chemical/hazmat, and universal kits, and using the wrong kit for the wrong substance is both ineffective and potentially hazardous. This guide explains what a standard spill kit contains, how the three main types differ, and how to verify that your kit is correctly specified for your site.

Standard Spill Kit Contents (All Types)

The following items are included in all correctly specified spill kits, regardless of whether they are oil-only, chemical, or universal:

How the Three Kit Types Differ

• 1
  Oil-Only Spill Kit: What's Different? Oil-only kits use white sorbents, a hydrocarbon-selective material that absorbs oils and fuels but repels water. This makes them effective on wet surfaces (standing water or rain), outdoors near drains, or near watercourses, because the sorbent picks up the oil and leaves the water behind.

  Do NOT use universal (grey) sorbents in oil-only applications near water. They will absorb the water as well as the oil, becoming saturated faster and leaving less capacity for the hazardous material.

  • Sorbent colour: white
  • Absorbs: hydrocarbons (diesel, petrol, motor oil, hydraulic fluid, lubricating oil)
  • Repels: water
  • Best for: fuel storage areas, vehicle workshops, outdoor drains, waterside sites, roads and infrastructure
• 2
  Chemical / Hazmat Spill Kit: What's Different? Chemical kits contain yellow sorbents, a universal sorbent compatible with acids, bases, and most solvents. Critically, they also include chemical-resistant gloves (not standard nitrile, which degrades in contact with many solvents and acids), a chemical-resistant apron or coverall in larger kits, a neutralising agent (acid spill: sodium bicarbonate-based; alkali spill: citric acid-based), pH indicator strips in some kits to confirm neutralisation before handling, and larger disposal bags with chemical-hazard labelling.

  Using a standard universal kit on a chemical spill without compatible PPE is hazardous: the kit absorbs the liquid but the first responder is not protected. Chemical kits must be specified to the specific substances held on site.

• 3
  Universal Spill Kit: What's Different? Universal kits use grey sorbents that absorb oils, fuels, water, coolants, and non-aggressive liquids. They are the most commonly held general-purpose kit for maintenance environments, vehicle workshops, and indoor use.

  Universal sorbents absorb water. They are NOT recommended for oil-spill response near water or in outdoor situations where rain is present, because the sorbent will absorb rainwater rather than remaining available for the oil.

  • Sorbent colour: grey
  • Absorbs: oils, fuels, coolants, water, most non-aggressive liquids
  • Best for: indoor maintenance, machinery areas, coolant leaks, non-hazardous liquid spills

What Is NOT in a Spill Kit (and Should Be Kept Nearby)?

• 1
  Fire extinguisher: some spill scenarios involve ignition risk (petrol, solvent). A CO2 or dry-powder extinguisher should be co-located with spill kits in fuel-risk areas.
• 2
  Drain seals: a separate product (a spill drain cover or drain guard) used to block drain inlets before a spill reaches them. Not standard kit contents but critical for sites near drains or watercourses.
• 3
  Used-sorbent waste manifest: required when passing used sorbents to a licenced waste contractor. Not provided in the kit but required for waste compliance.
• 4
  EPA incident notification contact: NESC (National Emergency Services Coordinator) number for EPA, IFI, and local authority notification in the event of a significant spill. Should be posted at or near the kit.

Frequently Asked Questions

• What is in a spill kit?

  A standard spill kit contains: sorbent pads, sorbent socks/booms, a sorbent roll, heavy-duty disposal bags and ties, gloves, goggles, and a laminated spill response instruction card. Chemical kits also include chemical-resistant PPE and neutralising agents.
• What is the difference between an oil spill kit and a universal spill kit?

  Oil-only kits use white sorbents that absorb hydrocarbons but repel water, ideal outdoors and near drains. Universal kits use grey sorbents that absorb oils and water, suited to indoor maintenance. Use oil-only kits near water sources; use universal kits for general indoor maintenance.
• What colour is a chemical spill kit?

  Chemical spill kits use yellow sorbents. The colour coding is: white = oil-only; grey = universal; yellow = chemical/hazmat.
