Administrative data
First-aid measures
If inhaled
Remove to fresh air. If it’s necessary – provide artificial respiration or give oxygen. Seek medical attention for any breathing difficulty.
In case of skin contact
Remove contaminated clothing. Mechanically clean contaminated skin and then wash with water and soft soap. Get medical attention. Wash
clothing before reuse.
In case of eye contact
Rinse contaminated eyes with eyelids widely opened with copious amounts of lukewarm water for 15-20 minutes. Consult a opthalmologist.
If swallowed
Make victim drink plenty of water. Induce vomiting. Seek medical attention.
Fire-fighting measures
Extinguishing media:
This product does not burn. Use extinguishing media suited to the materials that are burning.
Suitable extinguishing media: carbon dioxide fire extinguisher; dry-chemical fire extinguisher ABC or BC; foam extinguisher;
Unsuitable extinguishing media:not defined, not apply compact water streams to the surface of the burning substance
Special hazards arising from the substance - Substance itself does not burn.
Advice for firefighters:
Special protective equipment for fire-fighters: boots, overalls, gloves, eye and face protection and breathing apparatus. Wear self contained
breathing apparatus for fire fighting. Attention! Not allow enter to groud water, waste water or drains.
Accidental release measures
Personal precautions, protective equipment and emergency procedures:
Avoid dust formation. Avoid breathing dust. Ensure adequate ventilation. Evacuate personnel to safe areas. Wear suitable protective equipment
(see section 8) to prevent any contamination of skin, eyes and personal clothing, in case of dustiness – wear respiratory system protection.
Remember about limited time of molecular filters protective work (molecular filter is marked with white colour and symbol P2).
Environmental precautions:
Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Discharge into the environment must be avoided., contaminated
area should be isolated from an environment. Keeping away from drains, surface and ground water. In case of water contamination inform proper
authorities.Contaminated soil must be changed. Used packagings should be transferred to companies authorised to their processing.
Methods and material for contaiment and cleaning up:
Pick up and arrange disposal without creating dust. Sweep up and shovel. Keep in suitable, closed containers for disposal.
Appropriate containment techniques may include:
a) bunding, covering of drains
b) capping procedures
Appropriate clean-up procedures may include:
a) neutralisation techniques
b) decontamination techniques
c) adsorbent materials
d) cleaning techniques
e) vaccuming techniques
f) equipment required for containment/ clean up (include the use of non sparking tools and equipment)
-never use: not defined
Handling and storage
Precautions for safe handling:
Recommendations: Avoid contact with skin and eyes. Avoid formation of dust. Provide appropriate exhaust ventilation at places where dust is
formed. Contaiment and measures to prevent fire as well as dust generation, prevent handling of incompatible substances, reduce the release of
the substance to envrironment, avoid spills and keep away from drains
Advice on general occupational hygiene:
When handling sodium molybdate 2-hydrate not eat, drink and smoke in work areas, wash hand after use, remove contaminated clothing and
protective equipment before entering eating areas.
Conditions for safe storage, including any incompatibilities:
In original, properly marked containers, in store house furnished with ventilation installation. Keep container tightly closed in a dry and wellventilated
place. Storage temperature below 35OC

Exposure controls / personal protection
Control parameters
PEL 4 mg/m3(molybdenum and its compounds as Mo)
TWA 10 mg/m3(molybdenum and its compounds as Mo)
TLV - C not established
PEB not established
Exposure control
-appropriate engineering controls
Ventilation at the workplaces in building. Provide eye safety shower near the workplaces.
-individual protection measures, such as personal protective equipment
a) eye/ face protection
Recommended, safety glasses. Use equipment for eye protection tested and approved under standard EN 166(EU).
b) skin protection
-hand protection
Recommended, gloves. The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374
derived from it.
-other
Choose body protection according to the amount and concentration of the dangerous substance at the work place i.e.: gauntlets, boots, body-suit
c) respiratory protection
Protective masks with molecular filter P2. Required when dusts are generated. Use respirators and components tested and approved under
appropriate government standards such CEN (EU).
d) thermal hazards: none
Hygiene measures
Avoid contact with skin, eyes and clothing. Wash hands and face before breaks and immediately after handling the product. Immediately change
contaminated clothing. Apply skin protecive barrier cream.
-environmental exposure controls
Immediately remove all waste – keep in tightly sealed, marked containers
Stability and reactivity
Stable under recommended storage conditions.
Conditions to avoid:
Moisture, heating. Releases water of crystallization when heated.
Disposal considerations
Waste treatment of the substance and contaminated packaging
-incineration, recycling, landfilling
Contaminated product should be submitted to manufacturer for cleaning or processing − in other cases it should be treated as chemical waste
and should act in accordance with local law regulations.
Packagings:
Emptied disposable packagings should be submitted to authorised recipient of wastes.
