Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating directly as 'санитар' (which is a medic/sanitary worker). The correct equivalents are 'дезинфицирующее средство', 'антисептик', or the loanword 'санитайзер'.
- Do not confuse with 'sanatorium' (санаторий).
Common Mistakes
- Misspelling: 'sanatizer', 'sanatiser'.
- Using it as a verb (the verb is 'sanitize').
- Over-applying to contexts where 'soap', 'detergent', or 'cleaner' is more precise (sanitizers specifically target microbes).
