Administrative data
First-aid measures
physician.
Emergency measure - Eyes: Rinse immediately with plenty of water and seek medical
advice.
Emergency measure - Skin: Wash off with plenty of water. Obtain medical attention.
Emergency measure - Ingestion: Call a physician immediately.
Fire-fighting measures
based on class B + D (DIN EN 2).
Never use: water, carbon dioxide, or foam.
Product arising from burning: Hydrogen bromide, carbon monoxide, carbon dioxide,
magnesium oxide.
Product determined by test: N
Protective equipment: Self-contained breathing apparatus.
Accidental release measures
Ensure adequate ventilation. Wear personal protective
equipment. Remove all sources of ignition, do not smoke.
Environmental precautions:
Do not flush into surface waters or sanitary sewer systems.
Avoid subsoil penetration. If the products contaminates
rivers, lakes or drains, inform the respective authorities.
Methods for cleaning up:
Never allow contact with water. Cover spilled material with
limestone powder. Sweep up or vacuum up spillage and collect
in suitable container for disposal.
Handling and storage
inhalation of the substance as well as skin and eye contact
are excluded. The substance should only be handled (in
particular filling, transfer, metered feeding and sampling)
in dry, inert protective gas.
Never allow water to come into contact with the product.
The access of air and/or moistured should definitely be
avoided at all stages of the work. In the case of handling
in open systems, any vapor that can form must be extracted
directly at the point of origin. In those cases in which
inhalation of the substance is possible in spite of the
technical protective measures that have been taken (above
all, closed system, extraction or good ventilation)
respiratory protection should be worn (e.g. :::). Even if
only short-term skin contact is possible, tested antistatic
and flameproof finished gloves (s. below) and suitable
antistic and flameproof protective clothing (e.g. s. below)
must be worn. Safe eye protection (e.g. goggles, if
applicable, with the additional use of a protective face
screen), is absolutely essential. Dry powder showers should
be installed in the immediate vicinity of the work area,
sufficient washing facilities should be available and eye
douches should be made available and their location
conspicuously labelled. After skin contact, the affected
parts of the skin shoud be cleaned thoroughly using (:::).
Contaminated clothing must be changed immediately. Special
skin-protection and skin-care measures are recommended. A
skin-protection plan must be drawn up.
Take precautionary measures against static discharges.
Electrical equipment should be protected with the
appropriate standard.
Protect hands by flame resistant gloves.
Protect skin and body by flame retardant protective
clothing.
Keep away from ignition sources. Do not smoke.
Hygiene measures:
Avoid any contact with skin and eyes. Keep away from food,
drink, and animal feedingstuff. When handling the product,
do not eat, drink, or smoke. Wash hands before breaks and at
the end of the workday.
Storage: Keep containers tightly closed in a dry and well-ventilated
place. Protect from direct sunlight.
Store at 20 - 50 °C. Product crystallises at temperatures
below T < 30 °C (reversible). Dissolution possible when
stirring at temperatures between T = 30 - 50 °C. Handle only
after complete dissolution of the precipitate.
Packaging of the substance and or preparation: Containers, drums.

Stability and reactivity
extremely flammable cyclopropane gas (F+; R12).
Chemical reaction with water: 2 C3H5-MgBr + 2 H2O ---> 2 C3H6 + MgBr2 + Mg(OH)2
Dust explosion: Not applicable.
Dust explosion determined by test: N
Disposal considerations
Industry - Possibility of neutralisation: Repackage in salvage packaging. Obtain professional help
(fire fighters).
Industry - Possibility of destruction: controlled discharge: Hydrolyse with water.
As flammable cyclopropane gas will develop, larger
quantities must be treated in specialised equipment.
Dispose of liquid organic phase by incineration.
Dispose of liquid aqueous phase by neutralisation, e. g.
with sulphuric acid. Discharge into sewer observing local
regulations.
Industry - Possibility of destruction - incineration: Direct incineration is feasible in specialised equipment.
Industry - Possibility of destruction - water purification: The aqueous phase after hydrolysis and neutralisation can be
discharged observing local regulations.
Public at large - Possibility of recovery/recycling: No method available.
Public at large - Possibility of destruction: controlled discharge: Get professional help (fire fighters). Transfer to salvage
packaging, follow procedures of 6.1.00.
Public at large - Possibility of destruction - incineration: See above.
Public at large - Possibility of destruction - water purification: See above.
