Guidance on Safe Use
Administrative data
First-aid measures
General advice:
First aid personnel should pay attention to their own safety. If the patient is likely to become
unconscious, place and transport in stable sideways position (recovery position). Immediately
remove contaminated clothing.
If inhaled:
Keep patient calm, remove to fresh air, seek medical attention.
Immediately administer a corticosteroid from a controlled/metered dose inhaler.
On skin contact:
Immediately wash thoroughly with plenty of water, apply sterile dressings, consult a skin specialist.
On contact with eyes:
Immediately wash affected eyes for at least 15 minutes under running water with eyelids held open, consult an eye specialist.
On ingestion:
Immediately rinse mouth and then drink 200-300 ml of water, seek medical attention.
Note to physician:
Treatment: Treat according to symptoms (decontamination, vital functions), no known specific
antidote.
Fire-fighting measures
Suitable extinguishing media:
water spray, foam, dry powder, carbon dioxide
Unsuitable extinguishing media for safety reasons:
Unknown
Specific hazards arising from the substance or mixture:
carbon oxides, phosphorus oxides
Advice for fire-fighters
Special protective equipment:
Wear a self-contained breathing apparatus.
Further information:
The degree of risk is governed by the burning substance and the fire conditions. Contaminated
extinguishing water must be disposed of in accordance with official regulations.
Accidental release measures
Personal precautions, protective equipment and emergency procedures:
Use personal protective clothing. Information regarding personal protective measures see, chapter 8.
Environmental precautions:
Contain contaminated water/firefighting water. Do not discharge into drains/surface
waters/groundwater.
Methods for cleaning up or taking up:
For large amounts: Pump off product.
For residues: Pick up with suitable absorbent material. Dispose of absorbed material in accordance
with regulations.
Handling and storage
Precautions for safe handling
No special measures necessary provided product is used correctly.
Protection against fire and explosion:
Take precautionary measures against static discharges.
Conditions for safe storage, including any incompatibilities
Further information on storage conditions: Keep container tightly closed and dry; store in a cool place.

Exposure controls / personal protection
Components with workplace control parameters
756-79-6: dimethyl methylphosphonate
Personal protective equipment
Respiratory protection:
Suitable respiratory protection for lower concentrations or short-term effect: Gas filter for
gases/vapours of organic compounds (boiling point >65 °C, e. g. EN 14387 Type A)
Hand protection:
Chemical resistant protective gloves (EN 374)
Suitable materials also with prolonged, direct contact (Recommended: Protective index 6,
corresponding > 480 minutes of permeation time according to EN 374):
e.g. nitrile rubber (NBR) - 0.4 mm coating thickness
Supplementary note: The specifications are based on tests, literature data and information of glove
manufacturers or are derived from similar substances by analogy. Due to many conditions (e.g.
temperature) it must be considered, that the practical usage of a chemical-protective glove in practice
may be much shorter than the permeation time determined through testing.
Manufacturer's directions for use should be observed because of great diversity of types.
Eye protection:
Tightly fitting safety goggles (cage goggles)(e.g. EN 166) and face shield.
Body protection:
Body protection must be chosen depending on activity and possible exposure, e.g. apron, protecting
boots, chemical-protection suit (according to EN 14605 in case of splashes or EN ISO 13982 in case of
dust).
General safety and hygiene measures:
Wearing of closed work clothing is required additionally to the stated personal protection equipment. No eating, drinking, smoking or tobacco use at the place of work Handle in accordance with good industrial hygiene and safety practice.
Stability and reactivity
Reactivity
No hazardous reactions if stored and handled as prescribed/indicated.
Chemical stability
The product is stable if stored and handled as prescribed/indicated.
Possibility of hazardous reactions
No hazardous reactions when stored and handled according to instructions.
Incompatible materials
Substances to avoid:
amines, carboxylic acids, halides
Hazardous decomposition products:
No hazardous decomposition products if stored and handled as prescribed/indicated
Disposal considerations
Must be disposed of or incinerated in accordance with local regulations.
Contaminated packaging:
Uncontaminated packaging can be re-used.
Packs that cannot be cleaned should be disposed of in the same manner as the contents.
