First-aid measures

Slightly irritating to eyes, skin and respiratory system.
Harmful: may cause lung damage if swallowed (Aspiration).
Effects on the CNS are possible.
Low systemic toxicity.

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.
- If irritation persists get medical advice/attention

Eye contact :
- Flush eyes with water thoroughly and continuously for 15 minutes.
- Remove contact lenses, if present and easy to do. Continue rinsing.
- If irritation persists get medical attention. The patient should be seen by an ophthalmologist.

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.
- 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.
- Absorption by Inhalation or Ingestion may cause CNS symptoms like headache, dizziness,
fatigue, muscular, weakness, drowsiness and lack of coordination.
- High doses may cause CNS depression (Fatigue, dizziness and possibly loss of concentration,
with collapse, coma and death in cases of severe over-exposure.)
- In case of ingestion the stomach should be emptied by gastric lavage under qualified medical
supervision.

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/may spread fire.

Specific hazards during fire fighting :
- Releases flammable vapors below normal ambient temperatures.
- When mixed with air and exposed to ignition source, vapors can burn in open or explode if
confined.
- Flammable vapors may be heavier than air and travel long distances along the ground before
igniting and flashing back to vapor source.
- Move containers from fire area if you can do it without risk.
- Fight fire from maximum distance or use unmanned hose holders or monitor nozzles.
- 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.

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.

Environmental precautions :
- Prevent product from entering drains.
- Prevent further leakage or spillage if safe to do so.
- If the product contaminates rivers and lakes or drains inform respective authorities.

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.
- Dike large spills and place materials in salvage containers.
- Water spray may reduce vapor; but may not prevent ignition in closed spaces.

Handling and storage

Handling :

Advice on safe handling :
- Use only non-sparking tools.
- Extinguish all ignition sources.
- Carefully vent any internal pressure before removing closure.
- Containers must be properly grounded before beginning transfer.
- Handle empty containers with care; vapor/residue may be flammable.
- All equipment must conform to applicable electrical code.
- This material may attack some forms of plastics, rubbers, and coatings.
- Isolate, vent, drain, wash and purge systems or equipment before maintenance or repair.
- Check atmosphere for explosiveness and oxygen deficiencies.
- Wear recommended personal protective equipment.
- Observe precautions pertaining to confined space entry.
- Do not breathe vapors or spray mist.

Advice on protection against fire and explosion :
- Keep away from heat/sparks/ open flames/ hot surfaces .
- Not smoking
- Take precautionary measures against static discharge..


Storage :
- Requirements 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.
- Containers must be properly grounded before beginning transfer.
- This material may attack some forms of plastics, rubbers, and coatings.
- Consult supplier(s) of these materials for specific recommendations.
- Steel drums are recommended for packaging.

Advice on common storage:
- Carbon Steel
