First Aid Measures

Emergency procedures for chemical exposure incidents

Inhalation

If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Evacuate the victim to a safe area as soon as possible. Loosen tight clothing such as a collar, tie, belt or waistband. If breathing is difficult, administer oxygen. If the victim is not breathing, perform mouth-to-mouth resuscitation.

Skin contact

In case of contact, immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Cover the irritated skin with an emollient. Cold water may be used. Wash clothing before reuse. Thoroughly clean shoes before reuse. Wash with a disinfectant soap and cover the contaminated skin with an anti-bacterial cream.

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. Cold water may be used.

Ingestion

If swallowed, do not induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to an unconscious person. Loosen tight clothing such as a collar, tie, belt or waistband.

Immediate Medical Attention

Get medical attention immediately. Seek immediate medical attention.

Accidental Release Measures

Spill cleanup procedures, containment, and environmental protection

Small spill

Dilute with water and mop up, or absorb with an inert dry material and place in an appropriate waste disposal container. If necessary: Neutralize the residue with a dilute solution of sodium carbonate.

Large spill

Corrosive liquid. Poisonous liquid. Stop leak if without risk. Absorb with DRY earth, sand or other non-combustible material. Do not get water inside container. Do not touch spilled material. Use water spray curtain to divert vapor drift. Use water spray to reduce vapors. Prevent entry into sewers, basements or confined areas; dike if needed. Call for assistance on disposal. Neutralize the residue with a dilute solution of sodium carbonate. Be careful that the product is not present at a concentration level above TLV. Check TLV on the MSDS and with local authorities.

Cleanup methods

Dilute with water and mop up, or absorb with an inert dry material and place in an appropriate waste disposal container. Absorb with DRY earth, sand or other non-combustible material.

Materials: inert dry material, DRY earth, sand or other non-combustible material

Stability and Reactivity

Chemical stability, hazardous reactions, and incompatible materials

Stability

The product is stable.

Reactivity

Highly reactive with metals. Reactive with oxidizing agents, organic materials, alkalis, water.

Hazardous reactions

Hydrogen chloride causes aldehydes and epoxides to violently polymerize.

Avoid

Incompatible materials, water. Isolate hydrogen chloride from heat, direct sunlight, alkalies (reacts vigorously), organic materials, and oxidizers (especially nitric acid and chlorates), amines, metals, copper and alloys (e.g. brass), hydroxides, zinc (galvanized materials), lithium silicide (incandescence), sulfuric acid (increase in temperature and pressure).

Incompatible

metals, oxidizing agents, organic materials, alkalis, water, alkali metals, carbides, borides, metal oxides, vinyl acetate, acetylides, sulphides, phosphides, cyanides, carbonates, copper and alloys (e.g. brass), amines, hydroxides, zinc (galvanized materials), lithium silicide, sulfuric acid.

Decomposition

Hydrogen chloride gas is emitted when this product is in contact with sulfuric acid. Reacts with most metals to produce flammable Hydrogen gas. It reacts with oxidizers releasing chlorine gas.
