Guidance on Safe Use

First-aid measures

Ingestion

Never attempt to induce  vomiting. Do not attempt to give any solid or liquid by mouth  if the exposed subject is unconscious or semi-conscious.      Wash out the mouth  with water.  If the exposed subject is fully conscious, give plenty of water to drink. Obtain medical attention.

Inhalation:

Using appropriate 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.

Skin Contact

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.

Eye Contact

Wash immediately with clean  and  gently flowing water.  Continue for at least  15 minutes. Obtain medical attention.

Fire-fighting measures

This material  is non-combustible.

Dust clouds  are  potentially  of very 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 °C. Ignition of a dust  cloud produces a weak dust  explosion.

Moderate pressure between 6 and  8 bar is produced during a dust  explosion.

Suitable extinguishing media:

No special requirements needed. Water  is recommended for fires involving packaging.

Special Protective equipment and precautions for Firefighters

Since  toxic, corrosive or flammable vapours might be evolved  from fires involving this material,

self contained breathing apparatus and  full protective equipment are  recommended for firefighters. Move containers from the fire area if possible     without increased personal risk.

If possible, contain  and  collect firefighting water for later disposal.

Specific hazards arising form the material

Toxic, corrosive or flammable thermal decomposition products, which might include  sulphur compounds, are  expected when the material  is             exposed to fire.

Accidental release measures

Personal precautions

Avoid dust  generation. Wear  protective clothing and  equipment consistent with the degree of hazard. Instruct  all personnel not involved in               clean-up operations to keep  at a designated safe distance.

Environmental Precautions:

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.

Decontamination procedures

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

General requirements

Avoid dispersion as a dust  cloud.

Depending upon  the scale of 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.

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 °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. At both ambient and  low humidity, this material  is of appreciable conductivity.  

Generation and accumulation of electrostatic charge is considered unlikely to occur  when handled in an earthed (grounded) environment.

At both ambient and  low humidity, this material  has  an extremely fast charge relaxation time. Accumulation of electrostatic charge is considered

unlikely to occur  when handled in an earthed (grounded) environment.

Conditions for safe storage

Keep  in tightly closed containers or packages away from moisture and  away from sources of ignition.

Avoid prolonged storage at elevated temperatures (greater than  room temperature, approximately 20 degrees C).

Exposure controls / personal protection

Containment

Open  handling should  be limited to small quantities. Consider use  of enclosures.

Ventilation

Local exhaust ventilation  (LEV) is recommended.

Administrative

Only authorised personnel may enter  the working area.

Personal protective equipment

Eye Protection

Wear  approved safety  glasses with side  shields or cover goggles if eye contact is possible.

Gloves

The selection of gloves  for a specific  activity must  be based on the material's properties and  on possible permeation and  degradation that may

occur  under  the circumstances of use. Glove selection must  take  into account any solvents and  other  hazards present. Potential allergic reactions can  occur  with certain  glove materials (e.g.  Latex) and  therefore these should  be avoided. Care  must  be exercised if insufficient data  are  

available and  further guidance should  be sought from your local EHS department.

Respirators

If respiratory protective equipment (RPE) is used, the type of RPE  will depend upon  air concentrations present, required protection factor as well as

hazards, physical  properties and warning  properties of substances present. Follow local regulations for respirator use  in the workplace.

Other equipment or procedures

Wear  appropriate clothing to avoid skin contact. An eye wash  station  should  be available.

Stability and reactivity

Conditions to avoid

Avoid direct sunlight,  conditions that might generate heat  and  dispersion as a dust  cloud.

Disposal considerations

Collect for recycling  or recovery if possible. The recommended method of disposal is incineration.

Wherever possible, disposal should  be in an on-site  licenced chemical incinerator, if allowed  by the incinerator licence or permit.   If no on-site  

incinerator is available, dispose of material  in a licenced commercial chemical incinerator.

Regulatory Requirements            

Observe all local and  national  regulations when disposing of this material.
