Dihydrogen Monoxide: Safety Information
Dihydrogen monoxide (DHMO, SF Fig. 1.1) is a chemical compound that is commonly used in lab investigations. This chemical compound, sometimes referred to as hydric acid, is colorless and odorless. DHMO is known to be a part of many environmental hazards, toxic substances, diseases, and disease-causing agents. Each year DHMO is listed as a contributing factor in thousands of deaths, and it contributes to millions of dollars of damage to personal property and the environment. However, DHMO continues to be used widely by industry, government, and consumers worldwide. See Table SF Table 1.1 for a summary of the uses, effects, and hazards of DHMO.
SF Table 1.1. Some uses, effects, and hazards of DHMO.
Dihydrogen monoxide is used
- as an industrial solvent and coolant,
- in nuclear power plants,
- by elite athletes to improve performance,
- in biological and chemical weapons manufacture,
- as a spray-on fire suppressant and retardant,
- as a hydrocarbon combustion byproduct in furnaces and air conditioning compressors,
- in pesticide production and distribution,
- as an additive to food products,
- in cough medicines and other liquid pharmaceuticals,
- in shampoos, shaving creams, deodorants and numerous other bathroom products,
- as a preservative in fresh produce, and
- in the coffee available at major coffee houses.

Dihydrogen monoxide
- is a major component of acid rain,
- contributes to soil erosion,
- leads to corrosion and oxidation of many metals,
- causes short-circuiting of electrical systems, and
- decreases effectiveness of automobile brakes.
|
Some hazards of dihydrogen monoxide are
- death due to accidental inhalation of liquid DHMO, even in small quantities,
- severe tissue damage caused by prolonged exposure to solid DHMO,
- severe burns from exposure to gaseous DHMO, and
- pre-cancerous tumors and lesions composed largely of liquid DHMO.
|
Symptoms of accidental dihydrogen monoxide overdose include
- excessive sweating or urination,
- a bloated feeling, nausea, or vomiting,
- electrolyte imbalance, and
- hyponatremia (dangerously low sodium levels, which can lead to heart, liver, and kidney failure).
