The SDS classifies Tesco Dishwasher Salt as not a hazardous substance under CLP (Classification, Labelling and Packaging) regulations. However, it does highlight specific risks:
| Hazard type | Risk level | Explanation | |-------------|------------|-------------| | Acute toxicity | None | Not toxic if swallowed in small amounts (but large amounts cause issues) | | Skin corrosion | None | Dry salt is not corrosive | | Eye irritation | Moderate | Coarse crystals can cause mechanical injury; brine (concentrated salt water) irritates eyes | | Environmental | Low | High concentrations in soil can harm plants; avoid dumping bags in gardens |
Key warning from the SDS: "May cause mechanical eye irritation. Ingestion of large quantities may cause hypernatremia (salt poisoning)."
Knowing the SDS is useless if you don’t apply the best usage practices. Here is your safety-integrated action plan:
Tesco sells dishwasher salt under its "Tesco Everyday Value" or standard "Tesco" own-brand label. It is 99.9% pure sodium chloride (NaCl) — chemically identical to table salt but with a coarser granule size and no anti-caking agents or iodine.
Key identifiers from the typical SDS:
Unlike rinse aid or detergent, dishwasher salt is not a detergent. Its sole job is to regenerate the water softener unit inside your dishwasher, preventing limescale buildup on your glasses and heating element.
If salt spills on the floor, sweep immediately (do not use a wet mop initially – you’ll spread brine). A dry spill is a slip hazard per SDS Section 6 (Accidental release).
Open your dishwasher. Remove the bottom rack. Look for a round cap (usually blue or gray).
SDSs (formerly MSDS) provide health, safety, and environmental information. For sodium chloride-based dishwasher salt the SDS is usually straightforward but you should know where to look and what it means.
