Guidance on Safe Use
Administrative data
First-aid measures
General informations: Remove all contaminated clothing. Bring injured person to fresh air, lie down comfortably, loosen tight clothing.
In case of eye contact: Rinse widely opened eye for several minutes under running water. Is advisable to use a eyewash. Do not attempt to neutralize, but further treatment by an ophthalmologist.
In case of skin contact: Wash the affected area immediately with plenty of soap and water and, if possible dab with polyethylene glycol 400. Then cover with sterile dressing (no fire bandages!) cover. Consult a doctor if skin irritation persists.
Following ingestion: Rinse mouth and drink plenty of water. Do not induce vomiting. Physician.
Following inhalation of fumes: After inhalation of acid fumes. As soon as possible a glucocorticoid aerosol, eg Ventolair®, should be inhaled repeatedly. Oxygen should be inhaled during difficulty in breathing. If health problems occur, seek medical attention.
Self-protection of the First Aider: Avoid contact with substance still present.
Most important symptoms and effects, both acute and delayed: Local tissue destruction and corneal opacity in the eye. The healing process can last for a long time.
Indication of any immediate medical attention and special treatment needed: Physician treating of a disease caused by an acid burn.
Fire-fighting measures
Suitable extinguishing media: Water spray, foam, carbon dioxide, extinguishing powder
Unsuitable extinguishing media: not known
Special hazards arising from the substance or mixture: None
Advice for fire-fighters: Metaphosphoric acid is not burning. The fire water is strongly acidic and reacts with metals liberating hydrogen. In closed rooms an explosive gas/air mixture can be formed.
Accidental release measures
Personal precautions, protective equipment and emergency procedures: Skin and eye contact must be prevented by protective eye glasses and gloves.
Environmental precautions: meta-Phosphoric acid must not be discharged into drains or waterways.
Methods and material for containment and cleaning up: Collect mechanically and place in corrosion-resistant containers for disposal. Solve smaller quantities with plenty of water and dilute it. Larger amounts previously neutralize with Sodium hydroxide. The dilute solutions can be supplied to the waste water. Here, the maximum permissible concentration must be maintained!
Handling and storage
Precautions for safe handling: Follow the safety instructions in SDS (Section 2.2)! Use acid-resistant equipment only.
Conditions for safe storage, including any incompatibilities: Packaging material of the manufacturer: metal container with PE inner bag.
Storage: meta-Phosphoric acid has to be stored dry in tightly closed, acid-resistant containers, in well ventilated areas, be stored separately from food, beverages and animal feed. Do not store together with alkalis. Storage class: 8B (non-combustible corrosive substances)

Exposure controls / personal protection
Personal protective equipment
Eye / Face protection: Tightly fitting protective goggles required
Respiratory protection: Required when dust forms (particle filter P2 according to DIN 3181).
Skin protection: Chemical protective gloves, e.g. consisting of nitrile rubber (Check for damage before use), Penetration time (value for permeation: Level 6, > 480 min, EN 374)
General health and safety measures: Avoid unnecessary contact with the product. Wash hands after work, change contaminated clothing. While using do not eat, drink or smoke.
Stability and reactivity
Reactivity: Reacts under heat formation with alkali (salt formation).
Chemical stability: No decomposition if used according to specifications. The product is hygroscopic and melts down on long term exposure to air. A de-glassing process (crystallisation) can occur.
Possibility of hazardous reactions: Reacts with alkalis (salt formation) under evolution of heat. Corrosive to metals at high temperatures. The concentrated aqueous solution reacts with many metals forming highly flammable hydrogen gas. In closed rooms an explosive gas/air mixture can be formed.
Conditions to avoid: Contact with alkali and metals.
Incompatible materials: Alkalis.
Hazardous decomposition products: In the case of high temperatures can occur fumes of phosphorus oxides
Disposal considerations
Waste treatment methods: After pretreatment, the product must be supplied in accordance with the hazardous waste regulations to an approved hazardous waste landfill. Do not dispose of the sewage system!
Waste disposal code: 060104
