The scope of hazards may be broader than the official classification; verify against the supplier's current safety data sheet before use. Hazard statements (H): H318: Causes serious eye damage H412: Harmful to aquatic life with long lasting effects Precautionary statements (P): P264: Wash thoroughly after handling P273: Avoid release to the environment P280: Wear protective gloves/protective clothing/eye protection/face protection P305+P351+P338: IF IN EYES: Rinse cautiously with water for several minutes; Remove contact lenses, if present and easy to do. Continue rinsing P310: Immediately call a POISON CENTER or doctor/physician P391: Collect spillage P501: Dispose of contents/container to an approved waste collection point ## Toxicology (LD50) LD50 (oral): 3000 mg/kg (rat) ## Synonyms - sodium chloride - 7647-14-5 - Table salt - Common salt - Sodium chloric - NaCl - Dendritis - Purex - Iodized salt - Top flake - Flexivial - Sodium chloride (NaCl) MODEL VIEWS - ball-and-stick model (flat projection): https://molgod.org/wp-content/uploads/mol-god/viewer/7647-14-5/sodium-chloride-cas-7647-14-5-ball-and-stick-model-flat-projection-v10.png - skeletal model (flat projection): https://molgod.org/wp-content/uploads/mol-god/viewer/7647-14-5/sodium-chloride-cas-7647-14-5-skeletal-model-flat-projection-v10.png - 2D structure: https://molgod.org/wp-content/uploads/mol-god/viewer/7647-14-5/sodium-chloride-cas-7647-14-5-2d-structure-v10.png (c) 2026 MolGod.org. All rights reserved. https://molgod.org/copyright/#images ## Regulatory compliance checklist Status based on: ADR 2025 (Table A), REACH Annex XVII, CLP Annex VI (harmonised classification), hazard class from the m14-spill DB, SVHC, GIS and the Polish OEL list. Principle: no data = no claim (we do NOT declare "no restrictions" without a basis). 3 required / 12 items [fulfilled] SDS (Safety Data Sheet) available (sds) How to comply: Requirement: current SDS compliant with Reg. 1907/2006 (REACH) Annex II, 16-section format. Source / form: https://echa.europa.eu/information-on-chemicals [required] Compliant CLP label (pictograms + signal word + H/P) (clp_label) How to comply: The label must include: GHS pictograms, the signal word (Danger/Warning), hazard (H) and precautionary (P) statements, and manufacturer details. Required since 2010 (substances) and 2015 (mixtures). Source / form: https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:32008R1272 [required] Chemical OSH training (substance-specific) (bhp_training) How to comply: Laboratory staff: initial training (general induction + job-specific) + refresher training every 5 years (or every 3 for engineering/technical positions). Documentation kept in personnel files. Source / form: https://isap.sejm.gov.pl/isap.nsf/DocDetails.xsp?id=WDU20040180169 [required] BDO registration (Polish Waste Database) (bdo_registration) How to comply: The GHS classification of this substance indicates properties that may render the waste arising from it hazardous (Regulation 1357/2014, HP properties — with concentration thresholds calculated from the content in the waste, not in the reagent). Whether this gives rise to an obligation to keep BDO records depends on the waste producer and the scale of activity (Art. 50 of the Polish Waste Act; exemptions include up to 100 kg/year of hazardous waste). This is not a statement of obligation for the purchaser. Source / form: https://bdo.mos.gov.pl/ [not applicable] ADR transport (international agreement) (adr_transport) How to comply: Under ADR 2025 the substance is not classified as dangerous goods for road transport — standard carriage. Always confirm the form/concentration against section 14 of the safety data sheet. Source / form: https://unece.org/transport/dangerous-goods/adr-2025-files [conditional] REACH registration (>1 t/year EU import) (reach_registration) How to comply: Importers/manufacturers ≥1 tonne/year must register the substance with ECHA (technical dossier + Chemical Safety Report if ≥10 t). Check the ECHA Annex VI / registered substances list. Source / form: https://echa.europa.eu/regulations/reach/registration [to be verified] SVHC notification (Substances of Very High Concern) (svhc_declaration) How to comply: SVHC status not verified against the available dataset — check the current ECHA candidate list; do not assume the absence of an entry. Source / form: https://echa.europa.eu/candidate-list-table [to be verified] REACH Annex XIV (authorisation list) (reach_annex_xiv) How to comply: Not verified against the ECHA Authorisation List — check REACH Annex XIV. Source / form: https://echa.europa.eu/authorisation-list [to be verified] REACH Annex XVII (use/marketing restrictions) (reach_annex_xvii) How to comply: No entry in the harmonised classification dataset (CLP Annex VI) for this CAS number — status of entries 28–30 (CMR ban) NOT VERIFIED; do not assume the restriction does not apply. The dataset of Annex XVII restrictions is also incomplete — check the consolidated Annex XVII and the harmonised CMR classification on the ECHA website. Source / form: https://echa.europa.eu/substances-restricted-under-reach [to be verified] OEL — Occupational Exposure Limit in the working environment (nds_workplace) How to comply: No NDS data in the MOL-GOD dataset (incomplete set — ~41 of ~600 substances in the list). Absence does NOT mean there is no NDS — check the full list in Dz.U. 2024 poz. 1017 (Regulation of the Ministry of Family and Social Policy of 4 September 2024), and where none exists apply the OEL from EU directives or values recommended by NIOSH/ACGIH. Source / form: https://isap.sejm.gov.pl/isap.nsf/DocDetails.xsp?id=WDU20240001017 [to be verified] GIS register (precursors / psychotropics) (gis_register) How to comply: Does not appear in the available working set of precursors (list incomplete). Absence is NOT a confirmation — verify against Annex I of Reg. (EC) 273/2004 and the GIS list before placing on the market.
