Guidance on Safe Use

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).

SpecialProvisions

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.
