Guidance on Safe Use
Administrative data
First-aid measures
General advice
Take off all contaminated clothing immediately.
Inhalation
If aerosol or mists are formed:
Possible discomfort: severe irritation of mucous lining (nose, throat, eyes), cough, sneezing, flow of tears
Move victims into fresh air.
If breathing difficulties occur:
Keep patient half sitting with upper body raised.
Consult a physician immediately.
Skin contact
Wash off immediately with plenty of water.
Consult a physician.
Eye contact
With eye held open, thoroughly rinse immediately with plenty of water for at least 10 minutes.
Continue rinsing process with eye rinsing solution.
Protect unharmed eye.
Call ambulance. (Cue: caustic burn of the eyes)
Immediate further treatment in ophthalmic hospital/ ophthalmologist.
Continue rinsing eye until arrival at ophthalmic hospital.
Ingestion
Do not induce vomiting.
Only when patient fully conscious:
Have the mouth rinsed with water.
Have patient drink plenty of water in small sips.
Notify ambulance immediately (keyword: chemical burn).
Notes to physician
Therapy as for chemical burn.
If substance has been swallowed:
Early endoscopy in order to assess mucosa lesions in the oesophagus and stomach which may appear.
If necessary, suck away leftover substance.
Fire-fighting measures
Suitable extinguishing media
foam, CO2, dry powder
Extinguishing media which must not be used for safety reasons
water
Specific hazards during fire fighting
Hazardous fumes in fires, specific to the product:
hydrogen chloride
Special protective equipment for fire-fighters
Have ready/wear respiratory protection equipment.
Accidental release measures
Personal precautions
Use personal protective equipment.
Keep away from sources of ignition - No smoking.
Environmental precautions
Do not allow substance to enter soil, bodies of water or sewage canals.
Methods for cleaning up
Soak up with inert absorbent material (e.g. sand, silica gel, acid binder, universal binder, sawdust).
Fill into marked, sealable containers.
To be disposed of in compliance with existing regulations.
Suitable binder: sand (for damming up), sawdust, universal absorbent
Handling and storage
Safe handling advice
Provide good ventilation or extraction.
Ventilators required at emission site.
Protect from moisture.
Advice on protection against fire and explosion
Take precautionary measures against static discharges.
Keep away from sources of ignition - No smoking.
Explosion protection equipment required.
Storage
Requirements for storage areas and containers
Keep containers tightly closed in a cool, well-ventilated place.
Protect from moisture.

Exposure controls / personal protection
Components with workplace control parameters
• Hydrogen chloride
CAS-No. 7647-01-0 EC-No.
231-595-7
Control parameters 5 ppm
8 mg/m3 Time Weighted Average (TWA):(EU ELV)
Control parameters 10 ppm
15 mg/m3 Short Term Exposure Limit (STEL):(EU ELV)
DNEL/DMEL and PNEC values
Engineering measures
If possible, use material transfer/filling, metering and blending plants that are closed.
If contact with gases or vapours cannot be excluded: Provide good ventilation or extraction.
Personal protective equipment
Respiratory protection
In case of leakage or if TLV is exceeded wear respiratory equipment with suitable filter or a self contained respiratory apparatus.
Hand protection
Glove material for example, butyl-rubber
Material thickness 0,5 mm
Break through time >= 480 min
Glove material for example, Fluorinated rubber (Viton)
Material thickness 0,4 mm
Break through time >= 480 min
Selection of protective gloves to meet the requirements of specific workplaces.
Suitability for specific workplaces should be clarified with protective glove manufacturers.
The information is based on our own tests, references from the literature and information from glove manufacturers, or derived by analogy with similar materials.
Remember that the useful time per day of a chemical protection glove may be much shorter than the permeation time determined according to EN 374 due to the many different influential factors involved (e.g. temperature).
Eye protection
close-fitting protective goggles (e.g. closed goggles)
Hygiene measures
Do not inhale vapours / aerosols.
Avoid contact with skin and eyes.
Remove immediately all contaminated clothing.
Smoking, eating and drinking should be prohibited in the application area.
Protective measures
Use protective clothing / face shield if necessary.
Stability and reactivity
Hazardous decomposition products
hydrogen chloride in case of hydrolysis and thermal decomposition
Hazardous reactions
Reacts violently with:
atmospheric humidity
water
alkalis
acids
alcohols
amines
strong oxidants
Disposal considerations
Product
With respect to local regulations, e.g. dispose of to suitable waste incineration plant.
No waste key number as per the European Waste Types List can be assigned to this product, since such classification is based on the (as yet undetermined) use to which the product is put by the consumer.
The waste key number must be determined as per the European Waste Types List (decision on EU Waste Types List 2000/532/EC) in cooperation with the disposal firm / producing firm / official authority.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
