Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Administrative data
First-aid measures
Emergency measure - Inhalation: Using proper respiratory protection, immediately remove the
affected person from exposure. Administer artificial
respiration if breathing has stopped.
Keep at rest. Seek prompt medical attention.
Emergency measure - Eyes: Immediately flush eyes with large amounts of water for at
least fifteen minutes, and seek prompt medical attention.
Emergency measure - Skin: Immediately flush area with large amounts of water, use soap
if available. Remove contaminated clothing, including
boots/shoes after flushing has begun.
Seek prompt medical attention (also if irritation persists).
Emergency measure - Ingestion: Do not induce vomiting. If individual is conscious, give
milk or water to dilute stomach contents.
Keep warm and quiet. Seek prompt medical attention.
DO NOT attempt to give anything by mouth to an unconscious
person.
Fire-fighting measures
Recommended extinguishing agent: Use water spray to cool fire exposed surfaces and to protect
personnel.
Product arising from burning: The active catalyst will induce fumes, smoke, aluminum
oxides, carbon dioxide and monoxide, hydrochloric acid, and
hydrofluoric acid.
Product determined by test: N
Protective equipment: The active catalyst will ignite upon exposure to air or
water, and will thermally decompose. Protective gloves,
clothing, boots, as well as an approved respirator should be
worn during fire fighting.
Accidental release measures
Emergency measures in case of spillage: Prevent additional discharge of material if possible to do
so.
Implement clean up procedures.
Recover spill deactivated (with water) material and store in
barrels until recycling or disposal. Material is expected
to react, deactivate, and sink in water environment.
Consult an expert on disposal of recovered material and
ensure conformity to local disposal regulations.
Handling and storage
Handling: The active material is to be used and transported in a
closed system under nitrogen pressure (5-30 psi).
Handle only under inert atmosphere, unless material is
completely deactivated.
Wear chemical resistant gloves, a chemical suit, rubber
boots and safety goggles, plus a face shield.
Before opening container, connect to dry, oxygen-free inert
system.
Keep away from heat and flame. Do not drop container and
keep up-right.
Storage: In closed container under nitrogen pressure (5-30 psi).
Ambient temperature.
Packaging of the substance and or preparation: Material is to be packaged in portable tanks (closed system)
under nitrogen (5-30 psi N2 pressure) (see Annex 4).

Stability and reactivity
Danger other than fire: The catalyst in its activated state will react with water
(and air) and may produce toxic fumes.
Chemical reaction with water: The thermal decomposition of the material may produce toxic
vapors, and will result in the deactivation of the catalyst.
Dust explosion: Not expected
Dust explosion determined by test: N
Disposal considerations
Industry - Possibility of recovery/recycling: The substance is maintained and used in a closed system for
the production of LLDPE and HDPE. Most of the substance
injected into the reactor becomes dispersed in the polymer
matrix. Any spent catalyst from line purges, ... is
collected in portable tanks and sent to offsite incineration
(~5 kg/day). A small percentage (~0.007 kg/occurence) may
be released during line purges.
Based upon typical plant activity, this activity would occur
no more than 5 days per year, and never more than once per
day.
Industry - Possibility of neutralisation: Upon contact with air, the active catalyst will react and
will quickly become deactivated (neutralization of the test
material).
The data, presented in this dossier, show that the
deactivated catalyst does not present any toxic effects to
health or the environment. In effect, the polymerization
(ie. production of polymers) process, occurring during
manufacture, neutralizes potential hazards of the active
catalyst.
Industry - Possibility of destruction: controlled discharge: The NSN substance is incorporated into the polymer matrix
(totally encapsulated by the polymer).
In a typical polymerization operation, a small amount (0.007
kg/day) may be released to air during line purging or
connection of hoses. Any small amount of substance released
into the air will be burnt, thus destroying the NSN
substance.
It is estimated that the polymer will contain about 157 wppm
of encapsulated NSN substance.
Industry - Possibility of destruction - incineration: A small amount (approx. 5 kg/day) of deactivated catalyst
from line, tank, and feeder scrubbing with amorphous silica
will be collected and shipped to offsite incineration. It is
anticipated that this spent silica would consist of about
25% oxidized NSN substance (i.e. deactivated catalyst).
Public at large - Possibility of recovery/recycling: The public, at large, will never be exposed to the active
catalyst.
Public at large - Possibility of neutralisation: For information only, as this is not applicable in EU where
the active catalyst will not be manufactured.
During manufacturing processes (eg. filter change-outs and
vessel maintenance) the filter and vessels are deactivated
with isopropanol and purged with nitrogen prior to opening
these pieces of equipment. Since the NSN substance is
deactivated and the equipment purged prior to opening, there
is essentially no potential for exposure to the NSN materia
l.
Public at large - Possibility of destruction: controlled discharge: Not Applicable
Public at large - Possibility of destruction - incineration: Not Applicable
Public at large - Possibility of destruction - water purification: Not Applicable
