First-aid measures

Product-Specific hazards and other issues :- Severe eye and skin irritant. Can cause corneal damages. Moderate respiratory tract irritant.- Systemic effects on CNS, liver and blood are possible. - Risk of serious damage to the lungs (by aspiration)General advice:- Always observe self protection methods.- Move out of dangerous area.- Remove contaminated shoes and clothing.- Consult a physician.- Show this material safety data sheet to the doctor in attendance.Inhalation:- Remove to fresh air and keep at rest in a position comfortable for breathing.- Do not leave the victim unattended.- Keep patient warm and at rest.- Immediately seek medical attention.- If breathing is difficult, give oxygen.- If unconscious place in recovery position and seek medical advice.- In the event of unconsciousness , apnea or cardiac arrest (no Pulse) apply cardiopulmonary   resuscitation.Skin contact:- Immediately flush affected area with plenty of soap and water for at least 15 minutes while  removing contaminated clothing and shoe.- Immediately get medical attention. Eye contact- Flush eyes with water thoroughly and continuously for 15 minutes.- Remove contact lenses, if present and easy to do. Continue rinsing.- Immediately get medical attention and provide for further treatment  by an ophthalmologist due   to possible caustic burn of the eyes..Ingestion- Clean mouth with water and drink afterwards plenty of water.- Do NOT induce vomiting.- Do not give milk or alcoholic beverages.- Never give anything by mouth to an unconscious person.- If vomiting does occur, have victim lean forward to reduce risk of aspiration.- Get medical attention immediately.Advice to Physician :-Treat symptomatically.  Treatment of overexposure should be directed at the control of  symptoms and the clinical condition of the patient.  - Vapors, skin absorption and ingestion can cause nausea, dizziness, headache and CNS   depression with general anesthesia, liver- and kindney-function disturbance, cardiovascular and   blood count effects. - If inhalation occurs signs and symptoms may include coughing, choking, wheezing, difficulty in   breathing, chest congestion, shortness of breath and/or fever. - The onset of respiratory symptoms may be delayed. Can cause pulmonary edema.- After rinsing affected eyes must be seen by an ophthalmologist

Fire-fighting measures

Suitable extinguishing media- SMALL FIRE: Use dry chemicals, CO2, water spray or alcohol-resistant foam  - LARGE FIRE: Use water spray, water fog or alcohol-resistant foam  Unsuitable Extinguishing Media Do not use solid water stream.  Specific hazards during fire fighting- Fine sprays/mists may be combustible at temperatures below normal flash point.  When mixed  with air and exposed to ignition source, vapors can burn in open or explode if confined.  Vapors  may be heavier than air.  May travel long distances along the ground before igniting and flashing  back to vapor source.  Fight fire from maximum distance or use unmanned hose holders or  monitor  nozzles.  Move containers from fire area if you can do it without risk.  Cool containers  with flooding quantities of water until well after fire  is out.  Withdraw immediately in case of  rising sound from venting safety devices or discoloration of tank.  Always stay away from tanks   engulfed in fire.  For massive fire, use unmanned hose holders or monitor nozzles; if this is    impossible, withdraw from area and let fire burn.  .Further information :- Collect contaminated fire extinguishing water separately. This must not be discharged into  drains.- Fire residues and contaminated fire extinguishing water must be disposed of in accordance with  local regulations.Special protective equipment for fire-fighters- Wear positive pressure self-contained breathing apparatus (SCBA).  Structural firefighters   protective clothing will only provide limited protection.

Accidental release measures

Personal precautions :- Use personal protective equipment.- Ensure adequate ventilation.- Remove all sources of ignition.- Evacuate personnel to safe areas.- Beware of vapors accumulating to form explosive concentrations. Vapors can accumulate in low  areas.      Methods for cleaning up- Eliminate all sources of ignition.  All equipment used when handling this product must be  grounded.  Do not touch or walk through spilled material.  Stop leak if you can do it without risk. - Prevent entry into waterways, sewers, basements or confined areas.  A vapor suppressing foam  may be used to reduce vapors.  Absorb or cover with dry earth, sand or other non-combustible  material and transfer to containers.  Use clean non-sparking tools to collect absorbed material.

Handling and storage

HandlingAdvice on safe handling- Keep container tightly closed when not in use.  Extinguish all ignition   sources.  Wear recommended personal protective equipment.  Containers must be properly   grounded before beginning transfer.  All electrical equipment should be grounded and conform   to applicable electric codes and regulatory requirements.  Check atmosphere for explosiveness   and oxygen deficiencies.  Observe precautions pertaining to confined space entry.  Check   periodically to confirm inhibitor content.  If below desired level, add extra inhibitor/mix well to be   effective.  Use only non-sparking tools.  Carefully vent any internal pressure before removing   closure.  Isolate, vent, drain, wash and purge systems or equipment before maintenance or    repair.  Handle empty containers with care; vapor/residue may be flammable.  - Avoid contact with skin and eyes.- Smoking, eating and drinking should be prohibited in the application area.- Take precautionary measures against static discharges.Advice on protection against fire and explosion- Keep away from sources of ignition - No smoking.- Take measures to prevent the build up of electrostatic charge.StorageRequirements for storage areas and containers :- Store closed drums with bung in up position.  Store only in tightly closed, properly vented  containers away from heat, sparks, open flame and strong oxidizing agents.  Vapor space above  stored liquid may be flammable/explosive unless blanketed with inert gas.    Can self-react/polymerize/liberate heat/raising temperature, pressure/possibly rupture container  unless properly inhibited.  Recommended and Unsuitable Materials for Storage  Container Advice : Carbon Steel.
