A leaking drum in a warehouse, hydraulic fluid beneath machinery and a container of cleaning chemical knocked over during maintenance are all workplace spills, but they may require very different responses.
Knowing what substances are present on site can help businesses prepare suitable spill-control equipment, procedures and training before an incident happens.
Here are seven common types of workplace spills and some practical points to consider when preparing for them.
1. Oil spills
Oil spills are common in workshops, manufacturing facilities, warehouses and locations where vehicles or machinery are operated.
They can involve:
- Engine oil
- Hydraulic oil
- Lubricating oil
- Gear oil
- Compressor oil
Even relatively small leaks can spread across smooth floors and create a slip hazard. Oil may also reach drains, equipment or pedestrian routes if it is not contained quickly.
Oil-only absorbents are designed for hydrocarbon-based liquids and are particularly useful where oil needs to be separated from water.
Typical products may include oil-only absorbent pads, socks, rolls and complete spill kits.
Regularly checking machinery for leaks can also help identify small problems before they develop into larger spills.
2. Fuel spills
Diesel, petrol and other fuels may be present around vehicle fleets, generators, workshops, construction equipment and fuel-storage areas.
Fuel spills require careful management because of the additional hazards associated with flammable substances and vapours.
Workplaces handling fuel should consider:
- Where fuel is stored or transferred
- The largest potential spill
- Nearby drains and waterways
- Sources of ignition
- Suitable absorbent products
- How contaminated materials will be disposed of
Oil-only absorbents may be suitable for many hydrocarbon fuel spills, but the workplace procedure and relevant safety information should always be followed.
Large, hazardous or uncontrolled fuel spills may require specialist assistance rather than routine workplace clean-up.
3. Chemical spills
Chemical spills can vary significantly depending on the substance involved.
Examples include:
- Acids
- Alkalis
- Cleaning chemicals
- Solvents
- Process chemicals
- Laboratory substances
Before attempting to deal with a chemical spill, workers need to know what the substance is and whether they are trained and equipped to respond.
The product label and Safety Data Sheet can provide important information about hazards, personal protective equipment, incompatibilities and emergency measures.
Chemical absorbents are available for many aggressive liquids, but one absorbent should never automatically be assumed suitable for every chemical.
Where there is uncertainty about the substance or the spill presents a serious risk, the area should be isolated and the site's emergency procedure followed.
4. Water and water-based liquid spills
Not every spill involves a hazardous substance.
Water, coolant, beverages, cleaning solutions and other water-based liquids can still create significant operational and slip hazards.
Common sources include:
- Leaking pipes
- Cleaning activities
- Damaged containers
- Roof leaks
- Process equipment
- Refrigeration systems
- Entrances during wet weather
General-purpose absorbents are commonly used for water and a range of non-aggressive workplace liquids.
The source should also be investigated rather than repeatedly treating the symptoms. A recurring puddle beneath equipment, for example, may indicate a maintenance problem that needs attention.
5. Coolant and maintenance-fluid spills
Workshops and manufacturing environments may use a variety of coolants, cutting fluids and other maintenance liquids.
These spills can occur when:
- Machinery develops a leak
- Containers are being transferred
- Equipment is serviced
- Hoses or connections fail
- Fluids are being replaced
Some maintenance liquids can leave floors extremely slippery even after the majority of the liquid has been absorbed.
The area may therefore require appropriate cleaning after the initial spill has been contained and absorbed.
Keeping suitable absorbents close to maintenance areas can help teams respond without searching for equipment elsewhere on site.
6. AdBlue and other vehicle-fluid spills
Sites operating diesel vehicles may store AdBlue alongside fuels, lubricants and other vehicle fluids.
A dedicated response arrangement can make sense where particular fluids are stored or dispensed frequently.
Common spill locations include:
- Fleet depots
- Transport yards
- Vehicle workshops
- Distribution centres
- Refuelling areas
Separating response equipment can also reduce confusion over which absorbents should be used.
Clear labelling of spill kits and storage locations can help workers identify the correct equipment quickly.
7. Unknown spills
An unidentified liquid should be treated differently from a familiar maintenance spill.
If workers cannot confidently identify what has leaked, they should not simply select an absorbent and begin cleaning it up.
Instead:
- Keep people away from the affected area
- Try to identify the source from a safe position
- Check nearby containers and labels
- Inform the responsible person
- Follow the site's emergency procedure
- Seek specialist assistance where necessary
Unknown substances may present chemical, biological, electrical or fire-related hazards that are not immediately obvious.
Matching spill-control equipment to the risk
There is no single spill kit that is automatically suitable for every workplace.
When deciding what equipment to keep on site, consider:
- The substances stored and used
- The maximum likely spill volume
- Where spills are most likely to happen
- Whether the area is indoors or outdoors
- Nearby drains and sensitive areas
- The distance to the nearest spill kit
- Who is expected to respond
- Required PPE
- How contaminated absorbents will be handled afterwards
Different areas of the same workplace may require different spill-control arrangements.
For example, a vehicle yard may benefit from oil-only spill equipment while an indoor production area may require general-purpose or chemical absorbents.
Keep spill equipment ready to use
Spill-control equipment should not simply be purchased and forgotten.
Include spill kits in regular workplace checks to confirm that:
- Kits remain in their assigned locations
- Absorbents are clean and dry
- Previous usage has been replenished
- Labels and instructions remain readable
- Disposal bags and supporting equipment are present
- Access to the kit is not obstructed
A simple inspection routine can help ensure the equipment is available when it is actually needed.
Prepare for the spills your workplace could realistically face
Effective spill preparation starts with understanding the liquids already present within the workplace.
Identifying likely spill types, locations and quantities can help businesses select more appropriate absorbents and position response equipment where it can be accessed quickly.
