The first symptom to appear will be irritation for all routes of exposure. In case of exposure, do not wait for symptoms to develop. Immediately start the recommended procedures below and call a physician, poison centre or hospital immediately. Describe the type and extent of exposure and the victim’s condition. If breathing has stopped, immediately start artificial respiration and maintain until a physician takes charge of the exposed person.
Inhalation: If experiencing any discomfort, immediately remove the exposed person from exposure. Get medical attention immediately if symptoms develop. Eye contact: Immediately flush with much water or eyewash solution, occasionally opening eyelids, at least 15 minutes and until no evidence of chemical remains. Remove contact lenses after a few minutes and rinse again. See physician immediately. Skin contact: Immediately flush with much water while removing contaminated clothing and footwear. Wash with water and soap. See physician immediately if irritation develops. Ingestion: If the exposed person is conscious, let him/her rinse mouth and drink several glasses of water or milk, but do not induce vomiting. If vomiting does occur, let him/her rinse mouth and drink fluids again . Never give anything by mouth to an unconscious person. Make the exposed person lie down and keep him/her steady. Get medical attention immediately. Note to physician : Irritated skin should be treated as usual against effects of acids or acid fumes. In case lungs are affected watch for pulmonary oedema. Probable mucosal damage may contraindicate the use of gastric lavage.
Extinguishing media and procedure: Dry chemical or carbon dioxide for small fires, water spray or foam for large fires. Use water spray to keep fire-exposed containers cool. Approach fire from upwind to avoid hazardous vapours and toxic decomposition products. Fight fire from protected location or maximum possible distance. Avoid heavy hose streams. Dike area to prevent water runoff. Firemen should wear self-co ntained breathing apparatus and protective clothing.
CH-acid will decompose when heated under formation of toxic and flammable gasses, e.g. hydrofluoric acid, hydrochloric acid and chlorine gas. The development of gasses may happen so fast that explosion of containers and drums may occure.
Observe all personal protection and safety precautions. Depending on the magnitude of the spill, this may mean wearing respirator, face shield or eye protection, chemical resistant clothing, gloves and boots when cleaning up spills. Personal exposure by splashing must be avoided.
Steps to be taken in case of spill:
It is recommended to have a predetermined plan for the handling of spills. Empty, closable vessels (not metal) for the collection of spills should be available. Stop the source of the spill immediately if safe to do so. Contain the spill to prevent any further contamination of surface, soil or water. Remove sources of ignition.
Cleaning method :
Spills on the floor or other impervious surface should be absorbed onto an absorptive material such as universal binder, hydrated lime, Fuller’s earth or other absorbent clays. Collect the contaminated absorbent in suitable containers. Rinse area with soda lye and much water. Absorb wash liquid with absorbent and transfer to suitable containers. Wash waters must be prevented from entering surface water drains. Large spills which soak into the ground should be dug up and transferred to suitable containers. Spills in water should be contained as much as possible by isolation of the contaminated water. The contaminated water must be collected and removed for treatment or disposal. Uncontrolled discharge into water courses must be alerted to the appropriate regulatory body.
The used containers should be properly closed and labelled.
Precautions to be taken in handling:
In an industrial environment it is recommended to avoid all personal contact with the product, if possible by using closed systems with remote system control. Otherwise the material should be handled by mechanical means as much as possible. Adequate ventilation or local exhaust ventilation is required. The exhaust gases should be filtered or treated otherwise. Splashing and the formation of aerosol or mist must be avoided.
Avoid contact with eyes, skin or clothing. Avoid breathing vapour and avoid exposure of eyes to vapour as well.
