> NaBr has a very low toxicity with an oral LD50 estimated at 3.5 g/kg for rats.[6] However, this is a single-dose value. Bromide ions are a cumulative toxin with a relatively long biological half-life (in excess of a week in humans): see potassium bromide.
At no point does the paragraph you linked suggest it's safe to substitute NaCl with any other sodium salt.
