Sidewalk Chalk Salt Calcium chloride TOXIC Severe GI burns

Ice Melt / Road Salt

Extreme Danger - Never Consume

Composition: Various chlorides (sodium, calcium, magnesium, potassium)

Why it's toxic:

  • Contains calcium chloride or magnesium chloride (caustic)
  • Heavy metal contaminants (lead, mercury, cadmium)
  • Chemical additives for melting efficiency
  • Dyes and anti-caking agents not safe for consumption

Symptoms of ingestion:

  • Burning mouth and throat
  • Nausea, vomiting, diarrhea
  • Confusion, drowsiness
  • Seizures (severe cases)

Pet danger: Extremely toxic to dogs and cats - can be fatal

Epsom Salt (Magnesium Sulfate)

Medical Use Only - Not Table Salt

Composition: MgSO₄·7H₂O (NOT sodium chloride)

Safe uses:

  • External: Bath soaking for sore muscles
  • Medical: Laxative (with doctor guidance)
  • Gardening: Plant fertilizer

Dangers of consumption:

  • Severe diarrhea and dehydration
  • Electrolyte imbalances
  • Heart rhythm problems
  • Muscle weakness
  • Respiratory depression (overdose)

Fatal dose: As little as 30g for children

Note: Sometimes used medically as laxative but ONLY under medical supervision

Bath Salts (Cosmetic)

External Use Only

Composition: Sea salt or Epsom salt + fragrances, oils, dyes

Why not edible:

  • Essential oils can be toxic when ingested
  • Artificial dyes not food-safe
  • Fragrances contain chemicals harmful if swallowed
  • May contain detergents or surfactants

Common toxic ingredients:

  • Synthetic fragrances
  • FD&C dyes
  • Sodium lauryl sulfate
  • Preservatives (parabens)

"Bath Salts" (Synthetic Drugs)

EXTREME DANGER - Illegal Stimulants

NOT ACTUAL BATH PRODUCTS - DANGEROUS DRUGS

What they are: Synthetic cathinones (mephedrone, MDPV, methylone)

Effects:

  • Extreme agitation and violent behavior
  • Hyperthermia (overheating)
  • Hallucinations and psychosis
  • Heart attack and stroke
  • Death

If someone has taken these: Call 911 immediately

Pool Salt

Not Food Grade

Composition: 99.8% pure sodium chloride

Why not for consumption:

  • Not processed to food-grade standards
  • No testing for food-safe contaminants
  • May contain anti-fungal or anti-algae additives
  • Produced in facilities not certified for food

Note: While chemically pure, lacks food safety certification

Water Softener Salt

Industrial Grade Only

Types:

  • Rock salt: Mined, contains impurities
  • Solar salt: Evaporated, fewer impurities
  • Evaporated salt: Purest form (still not food-grade)

Contaminants:

  • Iron
  • Manganese
  • Heavy metals
  • Insoluble minerals

Health risks: Unknown contaminant levels unsafe for consumption

Common Household Salt Chemicals

Calcium Chloride (CaCl₂)
  • Use: Ice melt, desiccant
  • Danger: Burns, extreme heat when dissolved
Magnesium Chloride (MgCl₂)
  • Use: Ice melt, dust control
  • Danger: GI irritation, CNS depression
Potassium Chloride (KCl)
  • Use: Water softener, fertilizer
  • Danger: Heart problems in large doses
Sodium Bisulfate (NaHSO₄)
  • Use: Pool pH reducer
  • Danger: Corrosive acid
Copper Sulfate (CuSO₄)
  • Use: Algicide, fungicide
  • Danger: Toxic heavy metal
Sodium Carbonate (Na₂CO₃)
  • Use: pH increaser, washing soda
  • Danger: Caustic, burns

The Bottom Line

Non-edible salts are everywhere in modern homes, from the garage to the bathroom. While they may look similar to table salt, they contain chemicals, impurities, or additives that make them dangerous or potentially fatal if consumed.

Golden rule: If it's not explicitly labeled as food-grade and sold in the food section, don't eat it. When in doubt, throw it out.
