When a chemical spill occurs, the time between the incident and the first responder making contact with the hazardous substance is measured in seconds. Having the correct personal protective equipment (PPE) to hand — and knowing how to use it — is not simply best practice. Under the Control of Substances Hazardous to Health Regulations 2002 (COSHH) and the Personal Protective Equipment at Work Regulations 1992, it is a legal duty.
This guide sets out the PPE requirements for spill response in UK workplaces, covering the selection, specification, and maintenance of each type of equipment.
The Legal Basis: COSHH and PPE Regulations
COSHH requires employers to assess the health risks from hazardous substances — including the risk of skin and eye contact during spills — and to implement appropriate controls. PPE is the last line of defence in the hierarchy of controls; engineering measures and procedural safeguards must be considered first. However, for spill response situations — which are by nature unplanned — PPE is often the primary and most immediate protection available to the first responder.
The PPE Regulations require that PPE provided to employees must be:
- Appropriate for the risks involved and the conditions of use
- Compliant with relevant standards (CE or UKCA marked)
- Compatible with any other PPE being worn simultaneously
- Maintained in good repair and replaced when necessary
- Accompanied by training in correct use
PPE Selection for Chemical Spill Response
The specific PPE required depends on the chemicals involved. Always consult the Safety Data Sheet (SDS) for each substance — Section 8 sets out the recommended PPE. The following table provides a general guide for common spill response scenarios.
| PPE Item | Minimum Specification | When Required |
|---|---|---|
| Chemical-resistant gloves | EN ISO 374-1 rated, appropriate material (nitrile, neoprene, butyl, PVC) | All chemical spill response |
| Safety goggles / face shield | EN 166 rated, sealed indirect-vent goggles or full-face shield | Acids, alkalis, solvents, any splash risk |
| Chemical splash suit / coverall | EN 13034 (Type 6) minimum for light splashes; EN 14605 (Type 4) for heavier exposure | Large spills, concentrated chemicals, overhead drips |
| Chemical-resistant boots | EN ISO 20345 with chemical resistance rating | Floor-level spills, pooled liquid |
| Respiratory protection | FFP3 minimum; full-face respirator with appropriate cartridge for vapours/gases | Volatile chemicals, confined spaces, large spills |
| Apron | PVC or neoprene, EN 13034 compliant | Light chemical work, minor spills |
Gloves: Getting the Material Right
Chemical-resistant gloves are the single most important item of PPE for spill response — and also the most commonly selected incorrectly. The key is matching the glove material to the specific chemicals you are handling. A nitrile glove that provides excellent protection against oils and fuels may offer minimal resistance to concentrated acids or ketone solvents.
The main glove materials and their general suitability:
- Nitrile — excellent for oils, fuels, many solvents and dilute acids; poor against ketones and concentrated oxidising acids
- Neoprene — good broad-spectrum resistance; suitable for acids, alkalis, and many solvents
- Butyl rubber — best resistance to highly polar solvents (acetone, MEK) and gases; highest specification for hazardous chemicals
- PVC — adequate for dilute acids and alkalis; poor solvent resistance; lowest cost option
- Latex — limited chemical resistance; primarily used for biological hazards; risk of allergic reaction
Always check the manufacturer's breakthrough time data for the specific chemical in question. A glove with a 10-minute breakthrough time is not suitable for an extended spill clean-up operation.
Eye and Face Protection
Safety spectacles (EN 166) provide impact protection but are not sufficient for chemical splash risk. For spill response involving liquids, use sealed indirect-vent goggles — these prevent liquid from entering around the lens. Where there is a risk of significant splash (large volumes, pressurised containers, overhead work), a full-face shield worn over goggles provides the highest level of protection.
Stocking Your Spill Kit with the Right PPE
Your spill kit should include appropriate PPE for the hazard level it is designed to address. A standard hydrocarbon spill kit typically includes nitrile gloves and safety goggles. For chemical spill kits used near more hazardous substances, consider including a disposable coverall and face shield as standard.
PPE included in spill kits must be inspected when the kit is checked and replaced as part of the kit restock process. Degraded or expired PPE provides a false sense of security and represents a serious risk to anyone relying on it in an emergency. Browse our range of chemical spill kits with integrated PPE to ensure your team is always prepared.
Training: The Missing Piece
Even the best PPE provides no protection if it is not worn correctly. COSHH requires employers to provide adequate information, instruction, and training. For spill response, this means regular drills, competency checks on donning and doffing procedures, and clear emergency procedures displayed in storage areas.
