Guidance on Safe Use
Administrative data
First-aid measures
Contact with the skin:
Immediately remove soiled or splashed clothing. Wash immediately with abundant water for at least 5 minutes, and then rub calcium gluconate at 2.5% solution into the affected area until 15 minutes after local pain ceases. If necessary, apply a dressing or bandage soaked in 10% calcium gluconate solution.
In case there is not calcium gluconate available, washing with water should be prolonged for 15 minutes.
For skin burns bigger than a human hand (approx. 150 cm²), administer also 6 effervescent calcium tablets dissolved in water (400 mg of calcium each) every 2 hours until the patient is admitted to hospital.
For very widespread burns, give the patient a full bath in a solution of 1-5% calcium gluconate.
Medical treatment should be sought as soon as possible.
Contact with eyes:
Wash eyes immediately with plenty of water for at least 10 minutes, keeping eyelids open.
Go urgently to an ophthalmologist.
Inhalation:
Remove the affected person from the danger area, make him as comfortable as possible and protect him from the cold. Administer calcium tablets as for skin contact. If his breathing is laboured, give him oxygen through a facemask.
Medical treatment should be sought as soon as possible.
Ingestion:
Get the patient to take 4 effervescent calcium tablets dissolved in water. If no such tablets are available, make him drink milk. Do not induce vomiting.
Medical treatment should be sought as soon as possible.
Fire-fighting measures
The product is non-combustible and non-comburent.
1. Extinguishing media
No restriction in case of fire in the vicinity.
2. Special hazards arising from the substance
When heated, the product can give off hydrogen fluoride and sodium fluoride
3. Advice for firefighters
Containers should be removed to a safe area if this can be done without danger.
Breathing apparatuses and full protective clothing should be worn when extinguishing fires.
Accidental release measures
1. Personal precautions, protective equipment and emergency procedures
Provide good ventilation.
Staff to deal with spill should be properly equipped. (See paragraph 8)
Restrict access to area until totally clean, the people who do not use personal protective equipment.
2. Environmental precautions
Prevent soil, water and drain pollution.
Extracted air, which may be contaminated with large amounts of dust, should be treated with a washing system using the moist way before being released into the atmosphere.
3. Methods and material for containment and cleaning up
Collect mechanically avoiding dust formation. Place the material collected in lockable vessels duly marked. Do not throw the residues to the drain. Afterwards, wash the area with plenty of water. When neutralisation is needed, see disposal considerations.
Handling and storage
1. Precautions for safe handling
Avoid inhalation, absorption and contact with the product.
Handle and open de vessel with care, avoiding spillage and dust formation. Provide good ventilation. Partially used vessels should be hermetically re-sealed after use and be returned to storage. Empty vessels contain residues and therefore they should be handled as if full.
2. Conditions for safe storage, including any incompatibilities
The store should be situated in a dry and well-ventilated place, adapted to toxic products, far from heat sources and incompatible products. The product should be stored in its original container, hermetically sealed. Do not store close to foodstuffs intended to human or animal consumption.
Suitable materials for packaging are plasticized paper vessels, plastic bags, plastic drums plasticized cardboard drums, plastic GRG.

Stability and reactivity
1. Reactivity
With strong mineral acids, SiF4 and HF.
2. Chemical stability
Stable under normal conditions. If it is used as per the rules no decomposition occurs.
3. Possibility of hazardous reactions
No data available.
4. Conditions to avoid:
Heating it above 160º C.
Moisture: the product should be kept dry.
Contact with steel and many other metals, especially in the presence of moisture.
Corrosive for glass and cement.
5. Incompatible materials
Strong mineral acid and concentrated alkalis
6. Hazardous decomposition products
Hydrogen Fluoride, Sodium Fluoride and Sodium Oxide.
Disposal considerations
1. Waste treatment methods:
Use as much quantity of product as possible in the production cycle.
The product, packed in dry sealed vessels should be given to an authorized waste agent in order to manage its elimination that will probably be done by means of a physicochemical treatment and later settlement in a controlled chemical waist weir.
Alternatively, the product can be dissolved in water and neutralized with an alkali. Fluoride ions can be removed using Calcium Hydroxide, which will precipitate insoluble Calcium Fluoride. The resulting sludge may be dehydrated, then depositing them in an authorized landfill for disposal. Liquid waste generated, neutralized and very diluted, can be treated in wastewater municipal plants.
Treatment of containers:
Empty the vessels completely before its treatment, using as much quantity of product as possible in the productive cycle.
Vessels, before their elimination or settlement, should be dust-removed with caution.
Once almost clean, vessels can be eliminated by their settlement in an authorized waste weir or, in any case, by burning at a legally authorized plant.
Non-contaminated packaging will be treated as if inert residues or as recyclable material.
