Why lead needs care
Lead is the standard material for dive weights because it is very dense: a compact piece weighs a lot and displaces little water. It is also a toxic metal. Handled sensibly it is safe to use, and divers have carried it for decades. Treated carelessly it can be a health hazard, particularly for children and for anyone who gets lead on their hands and then eats or touches their mouth. This guide covers how to handle, clean, store and dispose of lead weights.
How lead gets into the body
- Swallowing: through hand-to-mouth contact after handling, or by eating or drinking without washing.
- Dust or fumes: from sanding, cutting or melting lead, which divers should never do.
- Children: small weights and bare lead are especially risky if a child can reach them.
Safe handling: the rules
- Wash your hands with soap and water after handling weights, before eating, drinking or smoking.
- Keep weights away from food and out of kitchens and eating areas.
- Do not put weights in your mouth or hold them against your face.
- Keep them away from children and pets.
- Do not cut, sand, melt or cast lead at home, because this creates dust and fumes.
Coated weights
Many weights have a plastic or rubber coating that stops direct contact with the lead, protects equipment and reduces corrosion. It is worth choosing coated weights, but coatings wear and chip, so inspect them regularly.
Cleaning and rinsing
- After salt-water dives, rinse the weights, belt and pouches in freshwater.
- Dry them before storing, so that nothing corrodes or grows mould.
- Wipe belts, buckles and pockets, and check that buckles and clips work smoothly.
Inspecting your weights
| Check | What to look for | Action |
|---|---|---|
| Coating | Chips, cracks, bare lead | Replace the weight or re-coat it according to the maker |
| Belt webbing | Fraying, stretching | Replace the belt |
| Buckle | Corrosion, sticking | Clean or replace |
| Pouches and pockets | Torn stitching, leaking shot | Repair or replace |
| Clips and keepers | Loose or missing | Replace |
Storing weights
- Store them dry, in a cool place, away from direct sunlight.
- Keep them in a closed box or locked cupboard out of the reach of children.
- Do not stack heavy weights where they could fall.
- Label the box so that others know what is inside.
Moving and lifting
Lead is heavy and awkward to carry. Lift with your legs, carry weights in a sturdy bag or box rather than loose and avoid carrying more than you can manage. When travelling, check your airline’s rules before you pack any weights, and consider renting at your destination.
If a weight is damaged or lost
- Damaged coating: replace the weight or re-coat it following the manufacturer’s advice.
- Lost weight: replace it with the same size so that your balance and weighting stay the same, and re-check your buoyancy.
- Lead dust or bare fragments: wash your hands and avoid spreading them. Ask your local waste authority how to dispose of them.
Disposal and recycling
Do not put lead in household waste or throw it into the sea. Lead is recyclable, and many scrap yards, recycling centres, dive shops and hazardous-waste facilities accept it. Ask your local authority or dive centre where to take old weights.
Lead-free alternatives
Lead-free weights, such as steel, exist in some places. They are generally less dense, so for the same weight they are bulkier, which may affect comfort and trim, and they can cost more. If you are concerned about lead, ask your local dive shop what is available.
A short routine
- After the dive, rinse the weights and gear in freshwater.
- Dry them out of direct sun.
- Inspect coatings, buckles, pouches and clips.
- Wash your hands.
- Store the weights safely, out of reach of children.
Where lead hides in your kit
It is not only the belt. Lead may be in belt weights, integrated pouches, trim weights on a tank band, ankle weights, and even in some tank-weight accessories. Treat all of these the same way when handling and cleaning them, and keep an inventory so that you know where each piece is.
Caring for pouches and soft weights
- Rinse pouches in freshwater, and wash them with mild soap if they get dirty.
- Let them dry fully before storing, and do not use heat or a tumble dryer.
- Inspect the stitching and closures, and replace pouches that leak shot.
- Do not open soft weights over a sink or floor. Replace damaged ones.
Teaching young divers good habits
Young divers and anyone new to the sport should learn the basics: wash hands after handling weights, never put weights near the mouth, keep weights in a closed box and ask an adult if a weight is damaged. A simple routine after every dive makes safe handling second nature.
Common questions and myths
- “Is a quick touch dangerous?” Brief contact is generally low risk, but hygiene rules still apply because lead on the hands can reach the mouth.
- “Do coatings make weights completely safe?” They reduce contact, but only while they are intact.
- “Can I melt old weights to make new ones?” No. Melting lead produces harmful fumes and is not safe at home.
- “Is it fine to leave weights outside?” Store them dry and away from children and pets, and not in a place where rain or damp can corrode them.
A checklist for the dive bag
- Soap or hand wipes to clean your hands after packing weights.
- A small towel to dry the weights.
- A spare retainer clip or keeper.
- A closed container for weights while transporting them.
Final thoughts
Looking after your weights takes only a few minutes after each dive and protects you, your family and your equipment. Combine good handling habits with correct weighting, as described in the scuba weights guide, and you will get years of safe use from the same set.
Common questions
Is lead dangerous to handle?
It is toxic if swallowed or inhaled as dust. Wash your hands after handling and keep weights away from food and children.
Can I dispose of old weights in the bin?
No. Take them to a recycling or hazardous-waste point.
Are coated weights safer?
The coating reduces contact with the lead and protects equipment, but inspect it regularly.
Are there lead-free options?
Some places sell steel or other weights. They are usually bulkier for the same weight.
