2. Composition / information on ingredients

Electrolyte containing sulphuric acid (H2SO4), Filter Material, proprietary catalyst alloy electrodes,

enclosed in a plastic based housing with attached metal connections.



3. Hazards Identification

The electrolyte inside the sensor constitutes the main potential hazard. This may leak out should the

housing be damaged or tampered with.



   3.1.    Inhalation of electrolyte:

           Inhalation is not an expected hazard unless heated to high temperatures. Mist or vapour

           inhalation can cause irritation to the nose, throat, and upper respiratory tract.

   3.2.    Ingestion of electrolyte:

           Corrosive. May cause sore throat, abdominal pain, nausea, and severe burns of the

           mouth, throat, and stomach.

   3.3.    Skin or eye contact of electrolyte:

           Corrosive. May cause redness, pain, blurred vision, and eye burns.

   3.4.    Aggravation of pre-existing conditions:

           Persons with pre-existing skin disorders or eye problems, or impaired respiratory function

           may be more susceptible to the effects of the substance.



4. First-Aid Measures

In case of leakage and:



   4.1.    Eye contact with electrolyte:

           Irrigate thoroughly with water for at least 15 minutes. Obtain medical advice.

   4.2.    Inhalation of electrolyte:

           Remove to fresh air. Rest and keep warm. Obtain medical advice if applicable.

   4.3.    Skin contact with electrolyte:

           Immediately flush the skin thoroughly with water for at least 15 minutes. Remove

           contaminated clothing and wash before re-use. Obtain medical advice if continued

           irritation.

   4.4.    Ingestion of electrolyte:

           If swallowed DO NOT INDUCE VOMITING. Wash out mouth thoroughly with water and

           give plenty of water to drink. Obtain medical advice.

5. Fire Fighting Measures



   5.1.    Fire:

           Not considered to be a fire hazard.

   5.2.    Explosion:

           Not considered to be an explosion hazard.

   5.3.    Fire extinguishing media:

           Use any means suitable for extinguishing surrounding fire.



6. Accidental release measures



   6.1.    Damage

           Should any CiTiceL® be so severely damaged or tampered with that the leakage of the

           contents occurs then the following procedures should be adopted:

           � Avoid skin contact with any liquid or internal component through the use of protective

              gloves.

           � Disconnect CiTiceL® if it is attached to any equipment.

           � Use copious amounts of clean water to wash away any spilt electrolyte, particularly

              important in equipment because of the corrosive nature of the electrolyte.

           � Observe first aid measures in case of eye contact, inhalation, skin contact or ingestion

              of electrolyte.
