Sanders usage and safety

A sander is a useful tool to save both time and effort when it comes to getting surfaces as smooth as possible. But working with one carries a particular set of safety risks.

Sanders are essential power tools for smoothing, shaping, and removing material from surfaces such as wood, metal, and plaster.

The most popular type for DIY at home is a detail sander (also known as corner sander) which is specially shaped to get into tight corners and edges.

Belt sanders are more heavy-duty to sand rough surfaces, for trimming, and for rounding and shaping. Orbital sanders used to be tricky to operate but modern models have an oscillating disc that helps you easily create a smooth, scratch-free surface.

Electric or cordless orbital sanders are the most common type for DIY, but air-powered orbital floor sanders are also available.

Key points

  • All sanders (or their chargers) must be fitted with a UK 3-pin plug and fuse.
  • Whichever type you choose, avoid buying second-hand.
  • Check the tool for any damage and to ensure the blades are in good working order before using it.
  • Wear a dust mask, safety glasses and hearing protection, and keep loose clothing and jewellery clear of the tool.
  • Unplug a sander when not in use or when doing maintenance on it.

Buying a sander

  • Whichever you choose, buy from a reputable retailer rather than a third-party seller online, as it may not have passed all the necessary safety checks.
  • Avoid buying second-hand sanders as you won’t know their history and they may not meet the latest safety standards. 
  • Key safety features include adjustable guards, work rests, efficient dust extraction, and emergency stop controls.
  • Register your sander so you can be contacted easily if there is a safety recall. It’s also much easier to return a faulty product or order a repair if it’s registered. 

Using a sander safely

  • Before you start, carefully read the manufacturer’s instructions and follow them.
  • Be aware that homes built before the mid-1960s may have lead-based paint as it wasn’t formally banned for domestic use until 1992. Don’t attempt to sand lead-based paint as this can lead to lead poisoning.
  • Check your appliance has a UK 3-pin plug. If it doesn’t, don’t try to use a UK travel adaptor as it may not meek UK safety standards. Get in touch with the retailer and ask for their advice.
  • If it has a cable, make sure the cable is long enough to easily reach the area you’re working in. If it isn’t, plug the sander into a fully-unwound extension lead to extend your reach.
  • Wear appropriate eye protection and a dust mask. Belt sanders can be especially loud, so wear hearing protection. Keep loose clothing and jewellery away from moving parts.
  • Make sure the item you’re sanding is properly secured.
  • Check the ventilation slots of the sander are clear of dust and debris before you begin.
  • Ensure you have a firm grip on the handle of the sander before turning it on. The sander should be kept flat and should be constantly moving as you work.
  • Only apply gentle pressure when using a sander. Don’t push down as the weight of the sander should do the hard work.
  • Keep the cable well out of the path of the sander as you work – draping it over your shoulder is safest.
  • Keep the plate underneath clean and free from dust.
  • Using a sander on metal creates sparks so make sure the tool is free of all sawdust and empty the dust bag before using it on a metal surface.
  • Work slowly in the same direction, overlapping passes and allowing the sander to go past the end without dipping.
  • Metal parts of the sander may become hot during use, so take care when handling.
  • When finished, lift the sander off the wood, turn it off, and wait for it to stop.
  • Switch off and unplug the tool when it’s not in use or before doing any maintenance on it such as attaching sandpaper, fitting or removing the dust canister, replacing or adjusting the belt on a belt sander.
  • Store your sander somewhere dry and indoors.
  • If you notice a burning smell or any unusual noises, switch the tool off immediately and contact the retailer and/or manufacturer.
  • An RCD (residual current device) in your consumer unit (fusebox) protects you from electric shocks should there be a fault with the sander. If you don’t have RCD protection, use an RCD plug on the socket where the tool is plugged in.
  • For a cordless sander, only charge the battery using the original charger or a replacement charger obtained from the manufacturer or reputable retailer.
  • Charge it in a safe place on a stable surface and disconnect batteries once they are charged. Don’t leave it charging overnight as this could be a fire risk.
  • If the battery emits any unusual odours, sparks, smoke, swelling, cracks, or you see any form of damage, stop using the battery immediately and make sure it is unplugged from the charger.
  • If you need a replacement or additional battery, or if your current battery no longer holds a charge, buy directly from the original manufacturer or authorised retailer.
  • Don’t use batteries from other manufacturers or battery adapters, as these may pose safety risks.

ALWAYS

  • Do plenty of research first before buying.  
  • Buy a known and trusted brand from a reputable retailer.
  • Register your sander with the manufacturer.
  • Apply gentle pressure when using a sander.
  • Make sure the item you’re sanding is properly secured. 

AVOID

  • Buying second-hand sanders or from third-party sellers online.
  • Using the sander if you spot any signs of damage.
  • Leaving the tool plugged in after use or when doing maintenance on it.
  • Pushing down as the weight of the sander should do the hard work.
  • Attempting to sand lead-based paint as this can lead to lead poisoning. 

Stay safe with electrical products

Check plugs and sockets

Don't ignore burn marks, ‘arcing’ (buzzing or crackling) sounds, fuses blowing, circuit-breakers tripping, or if it feels hot to touch.

Unplug and contact the retailer, manufacturer, or a qualified repair technician. 

Protect with an RCD

An RCD (residual current device) in your consumer unit (fusebox) protects you from electric shocks if a product is faulty.

If you don’t have RCD protection, use an RCD plug on the socket where the product is plugged in.

Fit smoke and heat alarms

Ensure there is at least one smoke or heat alarm per floor in your property. Fit enough alarms to cover all areas where a fire could start.

Test alarms at least once a month. Replace them every ten years or when the replace by date is reached.

Additional info

Electric sanders generally consume between 300W and 1000W of electricity, making them relatively low-energy handheld power tools compared to heavier machinery.

Common handheld orbital or belt sanders typically run at 300W-500W, offering high efficiency and significant energy savings (up to 90 per cent) over pneumatic alternatives.

Selected FAQs

If you’re unsure about an appliance or product, you’re not alone. These FAQs bring together expert advice and answers to the questions people ask us most, so you can feel more confident at home.

It is recommended that periodic inspection and testing is carried out at the following times:

  • for tenanted properties, every 5 years or at each change of occupancy, whichever is sooner
  • at least every 10 years for an owner-occupied home
  • at least every 5 years for a business

The Landlords and Tenant Act 1985 requires landlords of properties with short leases to keep the electrical wiring in repair and in proper working order. We recommend landlords arrange for periodic inspection and testing to be carried out by a registered electrician at the relevant intervals shown above.

Periodic inspection and testing of the electrics should be carried out more frequently on the places and premises listed here:

  • 3 years for a caravan
  • 1 year for a swimming pool

Periodic inspection and testing should be carried out only by electrically competent persons, such as registered electricians.

First, you need to find out whether the electrician you used is actually registered. To do this, contact the operator of the scheme they have claimed to be part of, and they will tell you whether this is the case. If they are registered, the scheme operator can guide you through their complaints procedure.

If you find out the electrician misled you and is not registered, you should report this to your local Trading Standards Department as they are breaking the law. We would also recommend that you get an Electrical Installation Condition Report (EICR) carried out on your home; this will assess any work that has been undertaken and will act as sufficient documentation to certify that work. This needs to be carried out by a registered electrician and unfortunately will be an added cost for you.

Has your electrical product been recalled?

Electrical products are recalled more regularly than you might think, but the response rate to a recall is often worryingly low. This means there are potentially millions of recalled electrical items still in UK homes.
