Administrative data
First-aid measures
This material is corrosive. If on skin, immediately or as time passes, the material deeply infiltrates under the skin.
It may lead to cardiopulmonary arrest.
Damages depends on how quickly remove the material.
Prepare, as appropriate, equipments for first-aid and emergency measures in advance.
If inhaled: Remove victim to fresh air. Tight clothing is loosened and eased. Blow the nose and rinse the mouth. If breathing is difficult, give oxygen inhalation. (Do not try mouth-to-mouth artificial respiration.)
If on skin: Remove/ take off immediately contaminated clothing, shoes or socks, and keep them away in a plastic bag. Wash out immediately contaminated body area with running water.
If in eyes: Rinse immediately the eyes with plenty and clean water more than 15 minutes. When rise the eyes, open the eyelids by fingers so that the eyeball can be moved all around. Try not to close the eyes due to pain. Get ophthalmologist's treatment as soon as possible.
If swallowed: Do not force vomiting nor give activated charcoal. If thevictim is conscious and the victim can drink some liquid, give100-200g of milk or water. In any case it is necessary to get medical attention immediately.
Protection of first-aiders: First-aiders should wear appropriate protective clothing depends on the situation.
Special note for doctors: Need rest and observation of progress.
Fire-fighting measures
Suitable extinguishing media: Small-scale fire: Dry chemical powder, foam or carbon dioxide.
Large-scale fire: Water shower.
Extinguishing media which shall not be used for safety reason: No information.
Special exposure hazards arising from the substance or preparation itself, combustion products, resulting gases: May produce irritating, corrosive or toxic gases or fume.
Special protective equipment for fire-fighters: See Section "6 ACCIDENTAL RELEASE MEASURES"
Other information: Move container from a fire area if it is not dangerous. If it cannot be done, spray water against the container and surrounding to keep cool.
When contacting to a reactive metal, this material may emit flammable hydrogen gas.
Accidental release measures
Personal precautions: Off-limits except responsible persons. Evacuate persons in leeward. Do not take action from leeward.
When take measures, wear protective respiratory equipment and clothing, as appropriate.
Environmental precautions: Attention not releasing products into public water area.
Methods for cleaning up: Recover any released material into a container, or enclose surrounding and neutralize if appropriate equipment is available and can take action safely.
Prevention of secondary hazards: Floor of storage/handling place should be made of a material which can prevent underground infiltration. Maintenance so that crack on the floor can be avoided.
Protective equipment for accidental release and fire fighting measures: Need dust respirator.
In addition rubber boots, rubber gloves, helmet and goggle for splash prevention, protective clothing, and other appropriate protective equipment should be used.
Handling and storage
Handling
Technical measures (Prevention of exposure to workers and fire/explosion): Handle in accordance with regulations specified by the Industrial Safety and Health Law and other related laws.
In case inhalation of vapours or skin contact is concerned, wear appropriate protective clothing and take action from windward.
Precautions (Local ventilation, overall ventilation, prevention of aerosol/dust production): When indoor handling, install appropriate ventilation system and keep concentration below the administrative control level.
Avoid leakage, overflow, dispersion and generation of vapours.
Avoid contacting to skin, eyes and clothing. See section "4 FIRST-AID MEASURES" when skin contact or in eyes.
Precautions for safe handling (Prevention of dangerous contact, avoidance of contact, etc): Storage apart from acidis.
Do not handle containers violently e.g., falling, damaging, or dragging.
Storage
Storage condition: Floor should be such that emission into public water area or underground can be prevented in case of accidental release.
Do not store together with acid.
Lock up containers and store in a place where avoiding the sunlight, cool and well ventilated.

Exposure controls / personal protection
Occupational exposure controls: Local ventilation, overall ventilation. Install safety shower, hand and eye washer near the handling place. Indicate the location of such equipment.
Respiratory protection: Dust respirator
Hand protection: Rubber gloves (neoprene, butyl)
Eye protection: Protective glasses, goggle, etc.
Skin and body protection: Helmet with shield.
Hygiene measures: Dust respirator should be exchanged regularly or used one way.
Stability and reactivity
STABILITY AND REACTIVITY
- Conditions to avoid: Heat
- Materials to avoid: Acids
- Hazardous decomposition products: Hydrogen fluoride gas is generated due to heat and contactwith acids.
- Other information: Dangerous polymerisation does not occur.
Electric or static electricity discharge dose not occur.
Disposal considerations
DISPOSAL CONSIDERATIONS
Waste from residues: Care should be made on the prevention of environmentalc ontamination when handling.
Neutralize with slurry of calcium hydroxide (attention to heat), and pH of the supernatant solution should range from 5.8 to 8.6. Follow water quality for F and N before
Control level for F: 8mg/L > public water area except marine area, 15mg/L > marine area.
Control level for N: 100mg/L > sum of nitrite-N and nitrate-N and 0.4 is multiplied by ammonium-N.
Follow control levels specified by local regulations in case they are below the above level.
Precipitation: When consign to a waste trader to deal with the waste, they should be certificated by local governor. Inform them manifest and follow the related laws and local regulations for disposal consideration.
Contaminated container and packaging: Do not reuse or dispose used/empty container as it is.
Containers should be cleaned up completely before reuse or disposal. Cleaning solution should be non-toxic.
