Guidance on Safe Use

First-aid measures

Emergency measure - Inhalation: Remove to fresh air.  If person is not breathing, give

artificial respiration.  If breathing is difficult,

administer oxygen.  Seek medical attention.

Emergency measure - Eyes: Irrigate affected eye(s) with copious amounts of water for

at least 15 minutes.  Seek immediate medical attention.

Emergency measure - Skin: Remove contaminated clothing.  Wash affected area with

copious amounts of soap and water for at least 15 minutes.

If irritation persists seek medical attention.

Emergency measure - Ingestion: Get medical attention immediately.  If ingestion has

occurred within the prior 5 minutes period, small amounts of

milk or water (approximately 2 ounces [60 millilitres] but

not to exceed 8 ounces [240 millilitres] for an adult) may

be administered.  However, if ingestion has occurred more

than 15 minutes previously, do not give oral liquids since

vomiting is likely to occur and may cause worsening of the

patient's condition.

Fire-fighting measures

Recommended extinguishing agent: Use appropriate medium for the underlying cause of fire and

the surrounding environment e.g. water, foam, CO2 or dry

chemical.

Product arising from burning: May include CO, CO2, NOx, SOx, HF.

Product determined by test: N

Protective equipment: Fire-fighters should wear full protective clothing including

self-contained breathing apparatus, chemical and flame

resistant protective clothing, gloves and boots.

Accidental release measures

Emergency measures in case of spillage: Protective clothing and respirator should be worn.  Collect

material to minimise dust generation.  Use a wet mop, damp

sponge or wet/dry HEPA vacuum.  Place collected material

into a suitable container for reclamation or disposal.  The

spill area should then be washed and ventilated.

Handling and storage

Handling: When engineering controls are not sufficient to control dust

exposure, approved respiratory equipment to EN136 standard

should be worn.  For manufacturing areas, skin protection

should be provided in the form of coveralls or gowns (or

other types of impervious material) along with latex or

other impermeable gloves.  Gloves should be changed

regularly and removed after overt contamination.  Rubber,

neoprene or other gloves may be required if solvents,

corrosives or other chemicals are present.  Chemical safety

glasses should be worn if a full face respirator is not

being worn.

Storage: Store away from heat sources under dry conditions in sealed,

upright unbreakable containers and ensure correct labelling.

Keep away from direct sunlight or strong incandescent light.

Packaging of the substance and or preparation: The substance is packaged in UN approved fibre drums in 20kg

drums with polyprophylene double-liners.

Stability and reactivity

Danger other than fire: May be incompatible with strong oxidising agents.

Chemical reaction with water: There is no adverse reaction with water.

Dust explosion: Compound has been tested as a combustible dust, with a class

1 explosion strength (ASTME 1226 Method).  The material

exhibits strong explosion characteristics if ignited as a

dust cloud.  The material is susceptible to accumulating

static charges during processing.  Provide suitable bonding

and grounding for containers and process equipment to

control static charges.  Powder handling equipment such as

dust collectors, dryers and mills may require additional

protective measures (e.g. explosion venting).

Dust explosion determined by test: Y

Disposal considerations

Industry - Possibility of recovery/recycling: Trace quantities are destroyed by biological oxidation in

the on-site and local authority municipal wastewater

treatment plants.  Larger quantities are destroyed by closed

cycle incineration.  No practical means of recovery or

recycling are known.

Industry - Possibility of neutralisation: No method of neutralisation is known.

Industry - Possibility of destruction: controlled discharge: Trace quantities are destroyed by biological oxidation in

waste water treatment plants.

Method: A641

Industry - Possibility of destruction - incineration: Incineration is recommended for larger quantities.  A

closed-cycle incinerator with scrubbers should be employed.

National regulations must be observed.

Method: A663

Industry - Possibility of destruction - water purification: Biological oxidation occurs at waste water treatment plants.

Public at large - Possibility of recovery/recycling: Not applicable as the substance will not enter the public

domain.
