15.2 CHEMICAL SAFETY ASSESSMENT
Summary of Product Safety Assessment
Hydrochloric acid is a highly corrosive liquid and it emits a pungent odor and strong fumes in moist air.
The color ranges from clear to slightly yellow. Hydrochloric acid is produced and sold as an industrial
product. It is used in applications such as steel pickling (surface removal of oxide and scale),chemical
manufacturing, oil-field acidizing, industrial cleaning and mining and metal production. Worker
exposure to hydrochloric acid is possible during manufacturing. Exposure is also possible during
industrial use. Direct consumer contact is unlikely.
Hazards of The Substance:
Eye or skin contact causes severe burns. Inhalation of fumes may be fatal. Ingestion may cause fluid
to form in the lungs and burns of the mouth and throat. Workers that use these materials must wear
personal protective equipment. Hydrochloric acid is not expected to accumulate in the food chain.
Hydrogen chloride gas released to the environment will distribute into the air and water. Hydrochloric
acid released into water may be toxic to aquatic organisms due to the resulting decrease in pH.
Hydrochloric acid is stable at typical use temperatures. Exposure to elevated temperatures can cause
this material to decompose. Heat is generated when hydrochloric acid is mixed with water and
spattering and boiling can result. Contact with sulfuric acid, amines, bases, carbonates, and oxidizers
should be avoided. Hydrochloric acid is corrosive to most metals. Contact with common metals
(i.e.zinc, magnesium, copper) generates extremely flammable hydrogen gas.

Exposure Potential
Based on the uses for hydrochloric acid, the public could be exposed through:
•
Workplace exposure
– Exposure can occur either in hydrochloric acid manufacturing facility or
in the various industrial or manufacturing facilities that use this substance. Hydrochloric acid is
produced, distributed, and stored in closed systems. Those working with these materials in
manufacturing operations could be exposed during maintenance, sampling, testing or other
procedures. Each manufacturing facility should have a thorough training program for employees and
appropriate work processes, ventilation, and safety equipment in place to limit unnecessary exposure.
•
Consumer exposure to hydrogen chloride and aqueous hydrochloric acid
– Hydrochloric acid
is manufactured for industrial use. Consumer exposure to this substance is unlikely. Gaseous
hydrogen chloride occurs naturally in the environment as a result of volcanic eruptions. Small amounts
of hydrogen chloride are released into the air by trash incineration. Hydrogen chloride in air is
removed by rainfall. Humans produce hydrochloric acid in their stomach to aid in the breakdown of
food and kill harmful microorganisms. Some household cleaning products such as toilet bowl cleaners,
tile and grout cleaners, and rust stain removers contain it.
•
Environmental releases
– All spills and leaks should be immediately contained to prevent
contamination of soil and surface or ground water. Hydrochloric acid released into water may be toxic
to aquatic organisms due to decreased pH. For small spills, it should be diluted with large quantities of
water and collected in suitable and properly labeled containers.
Large release
–Industrial spills or releases are infrequent and generally contained. Hydrochloric acid
will vaporize into a gas when spilled or released. If this material is released, the flow should be
stopped and the spilled material should be contained if possible. Vapor suppression foams should be
applied until spill can be cleaned up. In the event of a large hydrochloric acid spill, the area should be
ventilated and the spilled material should be contained if possible. Personnel should be evacuated
upwind of the spill. Only trained and properly protected personnel should be involved in clean-up
operations. A positive-pressure, self-contained breathing apparatus (SCBA) is recommended for
emergency work. Neutralization should be attempted by adding materials such as limestone, lime, or
soda ash. Recovered material should be pumped into suitable and properly labeled containers. In
case of fire
– These materials do not burn. Firefighting should be done in a manner appropriate for the
material that is burning. People should be kept away. They should be stayed upwind keeping out of
low areas where fumes can accumulate. Fire should be isolated and unnecessary entry should be
denied. The application of water is not recommended, but may be applied as a fine spray when other
extinguishing agents are not available.
Environmental Information
Hydrogen chloride does not accumulate in the food chain because of its high water solubility.
Hydrogen chloride in air will be removed by rainfall. In water, hydrogen chloride dissociates (breaks
up) into hydronium ions (H
+
) and chloride ions (Cl
–
). The dissociation of hydrogen chloride in water
lowers the pH of the water, making it more acidic. pH Levels below 5 could be toxic to fish and other
aquatic organisms.
