Chemical data sheets

Data sheets are compiled to let the common people know the risks of a chemical. They are accurate and have to be.
Lets compare the chemicals sodium fluoride and say boron.
We will start by looking at the headlines in the data sheets.
Sodium fluoride
These headings were taken from the data sheet of Sodium fluoride.
Note the number of pages

EXPOSURE CONTROLS/PERSONAL PROTECTION Issued: 25/03/2015 Substance No: 000031020001 Control Parameters: No value assigned for this specific material by Safe Work Australia. However, Workplace Exposure Standard(s) for constituent(s): Version: 6 Fluorides (as F): 8hr TWA = 2.5 mg/m3 Page 3 of 7 As published by Safe Work Australia Workplace Exposure Standards for Airborne Contaminants. TWA - The time-weighted average airborne concentration of a particular substance when calculated over an eight-hour working day, for a five-day working week. These Workplace Exposure Standards are guides to be used in the control of occupational health hazards. All atmospheric contamination should be kept to as low a level as is workable. These workplace exposure standards should not be used as fine dividing lines between safe and dangerous concentrations of chemicals. They are not a measure of relative toxicity. Safety Data Sheet Appropriate engineering controls: Ensure ventilation is adequate and that air concentrations of components are controlled below quoted Workplace Exposure Standards. Keep containers closed when not in use. If in the handling and application of this material, safe exposure levels could be exceeded, the use of engineering controls such as local exhaust ventilation must be considered and the results documented. If achieving safe exposure levels does not require engineering controls, then a detailed and documented risk assessment using the relevant Personal Protective Equipment (PPE) (refer to PPE section below) as a basis must be carried out to determine the minimum PPE requirements. Individual protection measures, such as Personal Protective Equipment (PPE): The selection of PPE is dependent on a detailed risk assessment. The risk assessment should consider the work situation, the physical form of the chemical, the handling methods, and environmental factors. OVERALLS, SAFETY SHOES, CHEMICAL GOGGLES, GLOVES, DUST MASK. Wear overalls, chemical goggles and impervious gloves. Avoid generating and inhaling dusts. If determined by a risk assessment an inhalation risk exists, wear a dust mask/respirator meeting the requirements of AS/NZS 1715 and AS/NZS 1716. Always wash hands before smoking, eating, drinking or using the toilet. Wash contaminated clothing and other protective equipment before storage or re-use.

Section 2: Composition and Information on Ingredients Composition: Name CAS # % by Weight Boron 7440-42-8 100 Toxicological Data on Ingredients: Boron: ORAL (LD50): Acute: 650 mg/kg [Rat]. 560 mg/kg [Mouse]. Section 3: Hazards Identification Potential Acute Health Effects: Slightly hazardous in case of skin contact (irritant, permeator), of eye contact (irritant), of ingestion, of inhalation. Potential Chronic Health Effects: Slightly hazardous in case of skin contact (permeator), of ingestion, of inhalation. CARCINOGENIC EFFECTS: Not available. MUTAGENIC EFFECTS: Not available. TERATOGENIC EFFECTS: Not available. DEVELOPMENTAL TOXICITY: Not available. Section 4: First Aid Measures Eye Contact: Check for and remove any contact lenses. In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Get medical attention if irritation occurs. p. 2 Skin Contact: Wash with soap and water. Cover the irritated skin with an emollient. Get medical attention if irritation develops. Serious Skin Contact: Not available. Inhalation: If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention. Serious Inhalation: Evacuate the victim to a safe area as soon as possible. Loosen tight clothing such as a collar, tie, belt or waistband. Seek medical attention. Ingestion: Do NOT induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to an unconscious person. If large quantities of this material are swallowed, call a physician immediately. Loosen tight clothing such as a collar, tie, belt or waistband. Serious Ingestion: Not available. Section 5: Fire and Explosion Data Flammability of the Product: Flammable. Auto-Ignition Temperature: 580°C (1076°F) Flash Points: Not available. Flammable Limits: Not available. Products of Combustion: Not available. Fire Hazards in Presence of Various Substances: Slightly flammable to flammable in presence of open flames and sparks, of heat. Non-flammable in presence of shocks. Explosion Hazards in Presence of Various Substances: Slightly explosive in presence of open flames and sparks. Non-explosive in presence of shocks. Fire Fighting Media and Instructions: Flammable solid. SMALL FIRE: Use DRY chemical powder. LARGE FIRE: Use water spray or fog. Cool containing vessels with water jet in order to prevent pressure build-up, autoignition or explosion. Special Remarks on Fire Hazards: Material in powder form, capable of creating a dust explosion. When amorphous boron is heated in dry ammonia, reaction proceeds with incandescence and hydrogen is evolved. Boron ignites in bromine vapor at 700 C. Boron ignites in chlorine @ 410 C. Fluorine attacks boron @ ordinary temperature and the resulting mass becomes incandescent. Iodic acid attacks boron below 40 deg. C and the resulting mass becomes incandescent. Concentrated nitric acid and boron react so violently that the mass is raised to incandescence. A mixture of boron and sulfur becomes incandescnet at 600 C. A reaction between nitrosyl fluoride and boron is accompanied by incandescence. Special Remarks on Explosion Hazards: Fine dust dispersed in air in sufficient concentrations, and in the presences of an ignition source is a potential dust explosion hazard. Silver fluoride reacts explosively Boron at ordinary temperatures. Section 6: Accidental Release Measures Small Spill: Use appropriate tools to put the spilled solid in a convenient waste disposal container. Large Spill: Flammable solid. Stop leak if without risk. Do not touch spilled material. Use water spray curtain to divert vapor drift. Prevent entry into sewers, basements or confined areas; dike if needed. Eliminate all ignition sources. Call for assistance on disposal. Section 7: Handling and Storage p. 3 Precautions: Keep away from heat. Keep away from sources of ignition. Ground all equipment containing material. Do not ingest. Do not breathe dust. Wear suitable protective clothing. If ingested, seek medical advice immediately and show the container or the label. Keep away from incompatibles such as oxidizing agents, acids. Storage: Keep container in a cool, well-ventilated area. Keep container tightly closed and sealed until ready for use. Avoid all possible sources of ignition (spark or flame). Section 8: Exposure Controls/Personal Protection Engineering Controls: Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below recommended exposure limits. If user operations generate dust, fume or mist, use ventilation to keep exposure to airborne contaminants below the exposure limit. Personal Protection: Safety glasses. Lab coat. Dust respirator. Be sure to use an approved/certified respirator or equivalent. Gloves. Personal Protection in Case of a Large Spill: Splash goggles. Full suit. Dust respirator. Boots. Gloves. A self contained breathing apparatus should be used to avoid inhalation of the product. Suggested protective clothing might not be sufficient; consult a specialist BEFORE handling this product. Exposure Limits: Not available

These two chemicals are used in different ways and have different warnings and severity of warnings 
One of these is put into water supply for drinking and the other is banned
One has bad health benefits and the other is good in small dosages.
you can chose one for internal consumption and the other is forced on you
Do your own research I know which one I would freely consume....
