Northvolt Skellefteå - 3 anställda har dött hemma mystiskt (2024)

Bland annat Litiumhydroxid, Dimetylkarborat, 1-metyl-2-pyrrolidinon, Kobolt, Nickel, Grafit med flera.

”En person uppvisade illamående, medan den andre personen hade lättare symptom”, skriver Northvolts presschef Matti Kataja i ett mejl.

The electrolyte is composed of a solvent of mainly organic carbonates and a conductor salt such as lithium hexafluorophosphate (LiPF6). Organic carbonates in liquid or gaseous form have a high flammability risk, while lithium hexafluorophosphate is harmful if ingested and causes severe skin and eye damage in case of contact. It can also cause organ damage in case of prolonged or repeated contact. If the electrolyte leaks and reacts with moisture or water, or if it ignites, hydrofluoric acid (HF) in liquid or gaseous form may be created. Its concentration will depend on the temperature of the combustion and the amount of electrolyte ignited.

Hydrofluoric acid (HF) represents a double threat to the human body. It is a corrosive product due to the hydrogen ions (H+) of the acid, which destroy the surface layers of the human body, and very toxic due to the fluoride ions (F–), which penetrate deep into the body and cause cell necrosis. The chelation of fluoride ions on calcium and magnesium causes hypocalcaemia and hypomagnesaemia as well as the destruction of underlying tissues. The depletion of these elements leads to an excess of potassium and causes a biological imbalance which can present as heart arrhythmias.

The higher the concentration of HF, the sooner the victim feels the consequences of exposure. For example, when the concentration of hydrofluoric acid is less than 20%, the pain appears only 24 hours after contact with the tissue. The severity and consequences of exposure will depend on the amount and concentration of HF and the surface area affected. Contact with HF can cause severe systemic effects (including cardiac arrest), severe burns to the skin, eyes or digestive tract, as well as irritation of the respiratory tract in the event of inhalation, including pulmonary oedema.

In addition to hydrofluoric acid, other toxic gases (carbon oxides) are also created and released during combustion of the electrolyte.

Dagarna innan Mahari Bakari avled hade han klagat på att det luktade stark på arbetsplatsen, berättar Ybrah Ruuso.

Vet ni vilka farliga ämnen som kan finns och kan uppstå i samband med batteritillverkning (och i batterifabriken)?
– Nej, därför tar vi hjälp av experter bland annat från Rättsmedicinalverket i vår utredning, för att ta reda på vilka ämnen som kan vara intressanta att titta närmare på. Vi försöker hitta en gemensam nämnare för de tre dödsfallen.
