Guidance on Safe Use

First-aid measures

Emergency measure - Inhalation: Using appriopriate personal protective equipment, move

exposed subject to fresh air. If breathing is difficult or

ceases, ensure and maintain ventilation. Give oxygen as

appropriate. The exposed subject should be kept warm and at

rest. Obtain medical attention in cases of known or possible

over exposure, or with symptoms including chest pain,

difficulty breathing, loss of consciousness or other adverse

effects, which may be delayed.

Emergency measure - Eyes: Wash immediately with clean and gently flowing water.

Continue for at least 15 minutes. Obtain medical attention.

Emergency measure - Skin: Using appropriate personal protective equipment, remove

contaminated clothing and flush exposed area with large

amounts of water. Obtain medical attention if skin reaction

occurs, which may be immediate or delayed.

Emergency measure - Ingestion: Seek medical attention immediately

Fire-fighting measures

Recommended extinguishing agent: No special requirements needed. Water is recommended for

fires involving packaging.

Product arising from burning: The substance is combustible and will burn if involved in

a fire, evolving noxious fumes (eg carbon and nitrogen

oxides and chlorine containing compounds).

Product determined by test: N

Protective equipment: Since toxic, corrosive or flammable vapours might be evolved

from fires involving this material, self contained

breathing apparatus and full protective equipment are

recommended.

Move containers from the fire area if possible without

increase personal risk.

If possible, contain and collect firefighting water for

later disposal.

Accidental release measures

Emergency measures in case of spillage: Fence or cordon the affected area and do not allow

individuals to touch or walk through the spilled material

unless wearing appropriate protective clothing. Avoid dust

generation.

Prevent entry into waterways, sewers, surface drainage

systems and poorly ventilated areas. If spill is outdoors,

cover with plastic sheet to minimise spreading or contact

with rain.

Collect and place it in a suitable, properly labelled

container for recovery or disposal. After all solid or

absorbent material has been collected; the area should be

vacuumed with HEPA filter-equipped apparatus. Following

removal of spillage, wash down spillage area with copious

amounts of water only if waste water can be directed to an

on-site waste water treatment system.

Water can be used for clean-up and decontamination

operations. No specific decontamination or detoxification

procedures have been identified for this material. Consider

use of water, detergent solutions or other soluble solvents,

for clean-up and decontamination operations.

Handling and storage

Handling: Avoid dispersion as a dust cloud.

Depending upon the scale of the operation, use of

appropriate exhaust ventilation is recommended to provide

routine control of fire and explosion hazards during

handling of this material.

Ignition Controls: Bond and earth (ground) all plant and

equipment to ensure that no isolated conductors are

present. Isolated conductors can accumulate sufficient

electrostatic charge to produce discharges of many hundreds

of milli-    Joules. Consider earthing (grounding) personnel

dealing with dusty operations. The maximum surface

temperature of enclosures potentially exposed to this

material should be the lower of the values obtained by

taking 2/3 of the minimum ignition temperature for a  dust

cloud or 75 K less  than the minimum ignition

temperature of the dust layer, with a maximum temperature of

325 Deg C.

Protective Systems: Assess operations based upon available

dust explosion information to determine the suitability of

preventive or protective systems as precautionary measures

against possible dust explosions. If prevention is not

possible, consider protection by use of containment, venting

or suppression of dust handling equipment. Where explosion

venting is considered the most appropriate method of

protection, vent areas should preferably be calculated based

on the Kst rather than the St value. If nitrogen purging is

considered as the protective system, it must operate with

an oxygen level below the limiting oxygen concentration. The

system should include an oxygen monitoring and shut down

facility in the event of excessive oxygen being detected.

At both ambient and low humidity, this material is of low

conductivity. Generation of electrostatic charge is

considered likely to occur even when handled in an earthed

(grounded) environment.

At both ambient and low humidity, this material has a very

long charge relaxation time. Accumulation of electrostatic

charge is considered very likely to occur even when handled

in an earthed environment. Under these conditions, it is

considered that this material might present a very high

riskn of producing an electrostatic discharge.

Storage: Keep in tightly closed containers or packages away from

moisture and away from sources of ignition. Avoid prolonged

storage at elevated temperatures (> room temperature,

approximately 20 Deg C).

Packaging of the substance and or preparation: SB-392033 is recieved and stored in double antistatic

polyethylene liners. The double liners are stored inside

either 20 L steel drums or fibreboard kegs.

Stability and reactivity

Danger other than fire: None reported.

Chemical reaction with water: None reported.

Dust explosion: This material is a non-combustible solid. Dust clouds are

potentially of low sensitivity to ignition from incendive

electrostatic discharges. Dust clouds are of very low

sensitivity to ignition from hot surfaces. No ignition or

exotherm of a powder layer observed up to 400 Deg C.

Ignition of a dust cloud produces a strong explosion. High

pressure between 8 and 10 bar is produced during a dust

explosion.

Dust explosion determined by test: Y

Disposal considerations

Industry - Possibility of recovery/recycling: Discharge to the environment is not aniticipated. Recovery

from minor spillages or accidental discharge is not

economically or technically feasible, and such waste

material will be disposed of by incineration.

In principle, it  may be possible to recover and recycle

larger spillages of uncontaminated material for subsequent

use.

Industry - Possibility of neutralisation: No chemical treatment is practicable to neutralise the

hazardous health properties.

The dust hazard will be minimised by good industrial

hygiene.

Industry - Possibility of destruction: controlled discharge: Collect for recylcing or recovery if possible. Contaminated

containers or spillages of solutions mixed  with inert

material (eg. sand or soil)  are incinerated. Wherever

possible, disposal should be in an on-site licenced chemical

incinerator.

Industry - Possibility of destruction - incineration: The substance can be disposed of by incineration by burning

under controlled conditions at a licensed waste treatment

processor in accordance with local regulations. Stack gases

should be scrubbed, because noxious fumes (eg. carbon,

nitrogen and chlorine oxides) could be formed.

Industry - Possibility of destruction - water purification: The substance should not normally be discharged directly

tothe sewage system or the aqueous environment. All waste

including aqueous waste are incinerated.

Industry - Possibility of destruction - other: None.
