Guidance on Safe Use
Administrative data
First-aid measures
General information: Avoid chance of exposure by any feasible way.
After inhalation: Move the affected person to fresh air.If breathing becomes irregular or ceases, apply mouth-to-mouth resuscitation or artifical respiration immediately. Get medical attention.
After skin contact: Immediately remove contaminated clothing, wash off the skin with plenty of water.
After eye contact: Rinse the eyes with water for several minutes with eyelids open wide. Having rinsed the eyes, obtain ophthalmologic attention as soon as possible.
After swallowing: Wash out the mouth with plenty of water, give plenty of water to drink, then obtain medical attenton immediately.
Information for doctor: The physician must be informed on the time, type and extent of exposure. If needed, show the safety data sheet to the physician.
Fire-fighting measures
Extinguishing media
Suitable extinguishing media: The extinguishing media must be chosen depending on the characteristics of burning substance. Available extinguishing media: water spray, extinguishing powder, carbon dioxid, foam.
Unsuitable extinguishing media: Full water-jet are not suitable for extinguishing.
Special hazards arising from the substance or mixture: Substanse is not combustible. Decomposition products: hydrogen cyanide.
Advice for firefighters: Outdoors stay on the weather-side and extinguish from there. In closed places, and in case of wreck, wear fireproof working clothes and use self-contained breathing apparatus.
Other information: Class of flammability hazard: not flammable
Accidental release measures
Personal precautions, protective equipment and emergency procedures: Only the trained personnel in charge of release is allowed to be present at the site of spilling, wearing the prescribed protective equipments.
Environmental precautions: Hinder the spilled substance from entering the soil, sewers or living water.
Methods and material for containment and cleaning up: Collect spilt substance aspiring to the lowest possible dust-level. Put the collected substance into adequately labelled empties and transport them to the site of disposal, then wash the contaminated area with plenty of water.
Reference to other sections: Not required.
Handling and storage
Precautions for safe handling: Take off contaminated clothing avoiding contamination of skin. It is necessary to wash a hand and a face with water and a soap
after the work made with the substance.
Conditions for safe storage, including any incompatibilities: Store it in a cool, dry, well-ventilated, free from direct sunlight place.Storage in a tightly fitting package.
Specific end use(s): Reagent.

Exposure controls / personal protection
Exposure controls
Appropriate engineering controls: Closed system, specific processes (eg. sampling) usage of local exhaust ventilation. The air-space of workplace cannot contain such substance which has an occupational exposure limit.
Individual protection measures / personal protective equipment: The personal protective equipment for the working process are determined by internal standards.
Eye/face protection: Wear closed protection glasses, or the respirator mask.
Skin protection: Closed protective clothing against particulate matter.
Hand protection: Protective gloves made of butyl and nitrile and neopren.
Respiratory protection: Respirator with B2-P3 filter type or with more protective filter cartridge.
Environmental exposure controls: Typically the substance cannot enter the environment.
Stability and reactivity
Chemical stability: Stable under normal circumstances.
Possibility of hazardous reactions: incompantibility with below materials.
Conditions to avoid: Sensitive to the following physical effects: intense heat.
Incompatible materials: magnesium, strong basics, nitrates, strong oxidisers, strong acids.
Disposal considerations
Suggestions for disposal procedures of the substance/product: It must be neutralized before the incineration.
Suggestions for disposal procedures of contaminated packaging (vessels): Flammable empties must be incinerated in waste increation plant, in compliance with local regulations.
