Household chemicals: who actually reads the label?

You bought a cleaning product, brought it home, or the courier left it at your door. It ends up under the sink or on a bathroom shelf, and that is usually where the story of the label ends. Household chemicals are in every home, but few people read what is written on them.

The previous article dealt with what, by regulation, should accompany a product in an advertisement or on a web page, and often does not. This one goes a step further, to what happens when the label is there and correct, but nobody reads it. The truth is a little uncomfortable. Here, the label is mostly read by chance, perhaps in the bathroom when there is nothing else to read. And yet it is exactly the label that carries the information on hazards and precautionary measures.

A label is not decoration

The label of a hazardous chemical is not marketing. It carries the hazard pictogram, the signal word, the hazard statements and the precautionary statements. The precautionary statements, in particular, describe how the product is safely used, stored and disposed of.

The signal word indicates the level of risk. Danger marks a more serious hazard, and Warning a milder one. The pictogram in the shape of a red diamond completes the picture. The corrosion symbol warns of damage to skin and eyes, the exclamation mark of irritation, and the health hazard symbol of more serious effects on the body.

This is where it says that the product should be kept out of the reach of children, stored in its original packaging and not mixed with other products. That is why a skipped label is not just skipped text. It is skipped safety instructions.

Misuse and improper storage

When the label is not read, mistakes become routine. Strong products are used in a closed bathroom without ventilation, so the fumes build up in a small space. Many labels explicitly require use with good ventilation.

Storage carries its own risks. Corrosive products are kept on high shelves, above head height, from where they can spill onto the face and eyes when someone reaches for them. Packaging or pressurized containers are also left in the sun or next to a heat source, even though the label advises against it.

Unlabelled containers are a particular risk. When a product is poured into an unknown bottle without a label, nobody knows anymore what is inside or how dangerous it is. That is why it is safest to keep the product in its original packaging.

Mistakes are also overlooked at disposal. The residues of some products and their empty packaging do not belong in ordinary waste, and that information is on the label too.

Dangerous mixing

The most dangerous habit is mixing. Many people think that two strong products make for stronger cleaning. Chemistry, however, works the other way here.

For example, bleach mixed with an acidic limescale remover releases chlorine. Bleach with ammonia produces chloramines. Both are gases that irritate the airways, and in a closed bathroom they become seriously dangerous. That is why chlorine-based products carry a specific warning that contact with acids releases a toxic gas, and many also add a note not to mix them with other products. But only those who read see that warning.

“Natural” is not the same as “harmless”

There is also a belief that natural means safe. Natural is often read as a synonym for harmless, and that is not true. Essential oils and eco and bio products also contain substances that can irritate the skin or cause an allergy.

The CLP criteria do not recognize natural origin as a mitigating circumstance. Limonene and linalool, components of citrus and lavender scents, become stronger allergens when they oxidize in air. Products with a pine or citrus scent are a good example. They sound pleasant, but in higher concentrations they can irritate the skin and the airways. That is why a product labelled natural also carries hazard statements, and they should be read just as with any other product.

How to use household chemicals safely

A few habits reduce the risk without much effort. First, read the label at least once, before the first use. Then keep the product in its original packaging, never in a drinks bottle.

In addition, keep it out of the reach of children and away from food. Do not mix different products, even when you are in a hurry. Just in case, keep the number of the Poison Control Centre somewhere visible, because in an accident every minute counts.

Children and pets

The greatest risk is carried by those who cannot read any label. Children are attracted to colourful packaging and bright liquids, and pets lick floors and surfaces. That is why a product left within reach, or in a container that looks like a drink, becomes a serious risk.

The solution is simple. Products should be kept locked away or up high, out of sight and out of reach. In addition, after cleaning, the space should be well ventilated and surfaces allowed to dry before a child or pet comes into contact with them.

Why this also matters for the market

The label protects the buyer, but also responsible manufacturers. Whoever invests in accurate labelling and clear instructions carries a cost that careless competitors skip. When the buyer does not read and does not ask for that information, that cost looks unnecessary.

That is why reading the label is also a market signal. Demand for accurate information rewards those who play by the rules. As long as the label is seen as decoration, doing things properly remains more expensive than cutting corners.

Frequently asked questions

Why is it important to read the label of a household product? The label carries the hazard statements and the precautionary statements. These instructions explain how the product is safely used, stored and disposed of, and so reduce the risk of an accident.

Does “natural” mean safe? No. The CLP criteria do not recognize natural origin as a mitigating circumstance. Natural ingredients, such as essential oils, can cause an allergy or irritate the skin.

Which household products must not be mixed? Bleach must not be mixed with acidic limescale removers or with ammonia. Such combinations release irritating gases. Always follow the instructions on the label.

How should household chemicals be stored? In their original packaging, tightly closed, out of the reach of children and away from food. Avoid heat and direct sunlight if the label requires it.

Where does it say how to use a product safely? On the label, in the section with the precautionary statements. For hazardous products, first aid instructions are there as well.
