5.1 - COSHH for Mobile and Home-Based Workers

The same COSHH law applies whether you work in a high-street salon, a converted spare room, or a client's kitchen. But the challenges are completely different. At home you have no commercial extraction system. On the road you're carrying chemicals in your car and working in spaces you don't control. This guide covers the specific risks and practical solutions for mobile and home-based beauty workers.

Quick rule of thumb: if you wouldn't leave a chemical next to a toddler's lunch or use it in a sealed car, don't assume your home salon or client's spare room is any safer.

The law hasn't changed - your setup has

COSHH (Control of Substances Hazardous to Health Regulations 2002) applies to every self-employed person who uses hazardous substances at work. The Health and Safety at Work etc. Act 1974, Section 3, makes it your duty to protect yourself and anyone else affected by your work - including family members at home and clients in their own houses.

The HSE doesn't give you a pass because you work from a bedroom. If anything, the risks are higher because domestic spaces weren't designed for chemical work.

Your COSHH assessment needs to reflect your actual working environment - not a generic salon template. A COSHH assessment written for a shop-front salon with commercial ventilation is useless if you're doing acrylics in a box room.

Tip for new starters: Your spare room is not a salon. Write your COSHH assessment for the actual space you work in, not a generic template. If your ventilation is one small window, say so and explain what you do about it.

Home-based workers: the specific risks

Ventilation is worse - sometimes much worse

A commercial salon should have mechanical ventilation or extraction. Your spare room probably has a window and a door. That's it.

This matters most for:

• Acrylic nails - monomer (methyl methacrylate or ethyl methacrylate) produces fumes that cause headaches, dizziness, and respiratory sensitisation. In a small room with the window shut, fume concentration builds fast.
• Keratin treatments - some release formaldehyde when heated. In a salon with extraction, fume levels stay below workplace exposure limits. In a small bathroom or bedroom, they can exceed them within minutes.
• Gel polish removal - acetone is highly volatile. Soaking 10 nails in a small room with no airflow means you're breathing it in the whole time.
• Spray tans - DHA (dihydroxyacetone) mist hangs in the air. Without extraction, it settles on every surface in the room and you inhale it throughout the treatment.

What to do:

• Open the window. Every time. Even in January.
• Use a portable extraction fan or desk-top fume extractor (£30-80). Position it between the chemical source and your face so fumes are pulled away from you, not across you.
• If you're doing spray tans, use an extraction tent (£150-300) with a built-in fan. Without one, DHA mist coats your walls, your carpet, your lungs.
• Never work in a room with no window at all. If your only option is an internal room, that service cannot safely be done there.

Storage is a genuine hazard

In a salon, chemicals live in a locked cupboard or store room away from the public. At home, they share space with your family.

The risks:

• Children accessing chemicals. Acrylic monomer, acetone, developer, colour - all toxic if swallowed, all capable of causing burns.
• Chemicals stored near food. Your kitchen cupboard is not a chemical store.
• Heat exposure. Products stored near radiators or in direct sunlight can degrade, produce fumes, or become more hazardous.
• Mixed storage. Oxidising agents (peroxide, developer) stored next to flammable liquids (acetone, monomer) is a fire risk.

What to do:

• Get a lockable metal cabinet (£40-80 from Screwfix or Amazon). Store all chemicals in it.
• Keep it in your work room, not the kitchen, bathroom, or anywhere children go unsupervised.
• Store oxidisers and flammables separately - or at minimum on different shelves with nothing flammable directly above the oxidisers.
• Check the safety data sheet (SDS) for storage temperature requirements. Most salon chemicals need to be kept below 25°C and away from direct sunlight.

Waste disposal is entirely on you

A salon usually has a commercial waste contract. At home, you don't. But the rules still apply.

• Leftover hair colour, developer, and bleach cannot go down the domestic drain in large quantities.
• Acetone cannot go down the drain - it's a solvent and a water pollutant.
• Sharps (if you do any treatments involving needles or blades) need a yellow sharps bin collected by a registered waste carrier.
• Empty chemical containers with hazard symbols should be rinsed and disposed of according to local council guidance - some can go in household recycling, some can't.

What to do:

• Small amounts of mixed colour can be rinsed down the drain with plenty of water (manufacturer guidance usually permits this).
• Bulk waste acetone: let it evaporate in a well-ventilated area, or collect it in a sealed container and take it to your local household waste recycling centre (HWRC). Check your council's rules - some accept small quantities of solvents, some don't.
• Get a sharps bin (£5-10 from pharmacy or online) if you do any treatments involving sharps. Arrange collection through a registered waste carrier (typically £80-150 per year for quarterly collection).
• Keep a waste disposal log. Note what you disposed of, how, and when.

Mobile workers: the specific risks

Transporting chemicals in your car

You're driving around with potentially hazardous substances in your vehicle. This isn't illegal for small quantities, but you need to do it safely.

The risks:

• A spill in a sealed car. Acetone or monomer spilling in your boot fills the car with fumes. At best, a headache. At worst, you're driving impaired.
• Containers tipping over. Developer, colour, bleach leaking onto upholstery, clothing, or other products.
• Heat. A car parked in direct sunlight can reach 50°C+ inside. Aerosols can explode. Peroxide degrades. Acetone fumes build up.

What to do:

• Keep all chemicals in a sealed, upright container - a plastic toolbox or dedicated carry case with a secure lid.
• Never transport chemicals in the passenger area. Boot only, ideally in a non-spill tray.
• Carry products in their original containers with lids securely fastened. Never decant into unlabelled bottles.
• Don't leave chemicals in the car overnight or in hot weather. Take them inside.
• Keep the SDS for every product you carry in the car (digital copies on your phone are fine).
• Carry a small spill kit: absorbent pads, disposable gloves, sealable plastic bags.

Working in client homes - you don't control the environment

This is the biggest challenge for mobile workers. You can't install extraction. You can't choose the room. You can't guarantee ventilation.

Common scenarios and what to do:

Keratin treatment in a small bathroom: The client's bathroom has no window and a weak extractor fan. Keratin treatments release fumes when you use the straightening iron. Formaldehyde workplace exposure limits can be exceeded in minutes in an unventilated room. The HSE short-term limit is 2 ppm over 15 minutes.

Solution: Don't do it. Move to the largest room in the house with openable windows. If the client insists on the bathroom, explain the health risk - to them and to you. If there's no suitable room, decline the booking. Your COSHH assessment should state the minimum ventilation requirements for this service.

Acrylic nails in a bedroom with no window open: The client wants to chat in their cosy bedroom with the heating on and windows shut. Within 20 minutes, monomer fume concentration is high enough to cause headaches and nausea.

Solution: Open the window before you start. Bring your portable extraction fan. Position it so fumes are drawn away from both of you toward the open window. If the client won't open the window, explain it's a health and safety requirement and you can't proceed without it.

Spray tan in a living room: DHA mist goes everywhere. It coats the sofa, the TV, the carpet, the client's cat. The client breathes it in. You breathe it in. It takes hours to settle.

Solution: Use a pop-up spray tan tent (essential for mobile spray tanners - not optional). The tent contains the overspray. Use a tent with extraction if possible. Lay down protective sheeting around the tent. The client should wear a nose filter. You should wear an FFP2 mask. After the session, wipe down the tent and leave it to air before packing it away.

Tip for new starters: Put your ventilation and space requirements in your booking confirmation message. It saves awkward conversations when you arrive and the room has no windows.

No control over the environment

When you arrive at a client's home, you might find:

• Children running around near your chemicals.
• Pets in the treatment area.
• No suitable table height, leading to you bending over and breathing in fumes at close range.
• A kitchen table that will be used for dinner in an hour - and you're using hair colour on it.

What to do:

• Set expectations in your booking confirmation. "Please ensure the room is well ventilated with a window open, children and pets are kept out of the treatment area, and a clear table/workspace is available."
• Bring protective sheeting for surfaces.
• Bring your own towels - don't rely on the client's.
• If conditions aren't safe, you can decline to proceed. You're within your rights. A polite "I can't safely do this service in this space - let's rearrange" is professional, not awkward.

Your COSHH assessment must reflect your actual setup

A generic COSHH assessment template won't work. Your assessment needs to cover:

Review your COSHH assessment every year, or whenever you add a new product, change your workspace, or start offering a new service.

PPE: the same rules, harder to enforce

At home and on the road, it's tempting to skip PPE because it feels less "professional" or you're in a casual setting. Don't.

• Gloves: Nitrile, every time you handle chemicals. Not latex (allergy risk to you and clients).
• Mask: FFP2 minimum for spray tans, acrylic dust, and any fume-producing treatment. A standard surgical mask does nothing for chemical fumes.
• Apron: Protects your clothes and skin from splashes. You're not in a salon uniform - your own clothes aren't disposable.
• Eye protection: If you're mixing bleach or developer, safety glasses prevent splashes. Yes, even at someone's kitchen table.

What happens if you get this wrong

• HSE enforcement: The HSE can inspect home-based and mobile businesses. It's rare, but it happens - especially after a complaint or incident. Fines start at £1,000 and can reach unlimited amounts for serious breaches.
• Insurance: Your public liability and professional indemnity insurer will ask whether you have COSHH assessments. If you don't, and a client has a reaction or injury, they may refuse to pay out.
• Civil claims: A client who suffers a chemical burn, allergic reaction, or respiratory issue can sue you. Without a COSHH assessment showing you identified and controlled the risk, you have no defence.

What to do next

1. List every chemical product you use - including cleaning products.
2. Get the safety data sheet for each one (manufacturer's website or ask your supplier).
3. Write a COSHH assessment that describes YOUR workspace - your actual room, your actual ventilation, your actual storage.
4. If you're mobile, set minimum requirements for client homes and put them in your booking confirmation.
5. Buy a lockable storage cabinet, a portable extraction fan, and proper PPE if you haven't already.
6. Review annually.
