3,5-dimethylpyridine

Guidance on Safe Use

First-aid measures

Skin Contact:  Wash exposed area twice with soap and water. The exposed area should be examined by medical personnel if irritation or pain persists after the area has been washed.

Eye Contact:  Rinse eyes immediately with large amounts of water for at least 15 minutes, occasionally lifting the eyelids. GET MEDICAL ATTENTION.

Inhalation:  Remove from exposure area to fresh air immediately. If breathing has stopped, give artificial respiration. Keep affected person warm and at rest. GET MEDICAL ATTENTION.

Ingestion:  If swallowed, contact physician or poison control center immediately.   Give oxygen if respiration is shallow.   GET MEDICAL ATTENTION. Do not give anything by mouth to an unconscious person.

Most important symptoms and effects, both acute and delayed:

Acute:  Methylpyridine derivatives such as lutidines are generally irritating to skin, eyes and mucous membranes. Vapors may be irritating to the respiratory tract. These materials are readily absorbed through the skin and may be considered toxic via oral, dermal and inhalation routes. Extended exposure (e.g., from saturated clothing) may lead to severe skin irritation and/or systemic poisoning. Symptoms may include headache, dizziness, nausea, nervousness, weakness, narcosis, sleeplessness, loss of appetite and possibly loss of consciousness.  Symptoms seen after ingestion or inhalation overexposures are expected to be essentially the same as those listed previously. Ingestion is not likely to be a primary route of exposure.

Delayed Effects:  None known.

Indication of any immediate medical attention and special treatment needed:

Thermal Exposure:  Not applicable.  

Note to Physician:  No specific indications.  Treatment should be based on the judgment of the physician in response to the reactions of the patient.  

Fire-fighting measures

Appropriate Extinguishing Media:  Water, fog, Foam, Carbon dioxide, Dry chemical

Special hazards arising from the substance or mixture:  Hazardous Products of Combustion:       

Toxic fumes may be released upon thermal decomposition (cyanides, nitrogen oxides, carbon monoxide).

Potential for Dust Explosion:       Not applicable.  

Special Flammability Hazards:       Severe explosion hazard in the form of vapor (within flammability limits) when exposed to heat, flame, static discharge.

Advice for firefighters:

Basic Fire Fighting Guidance:       Wear self-contained breathing apparatus and full protective clothing (i.e., Bunker gear).  Skin and eye contact should be avoided.  Normal fire fighting procedures may be used.  

Flammability Classification (EU CLP):  Category 3.  

Accidental release measures

Personal precautions, protective equipment and emergency procedures

Evacuation Procedures:  Isolate the hazard area and deny entry to unnecessary and unprotected personnel.  

Special Instructions:  Remove all contaminated clothing to prevent further absorption.  Decontaminate affected personnel using the first aid procedures.  Leather shoes that have been saturated must be discarded.  

      

Environmental precautions:

Prevent releases to soils, drains, sewers, and waterways.  

Containment Techniques and Clean-up Procedures:       

Remove all ignition sources. Ventilate the area of spill or leak. Wear protective equipment during clean-up. For small spills, use suitable absorbent material and collect for later disposal. For large spills, the area may require diking to contain the spill. Material can then be collected (eg., suction) for later disposal. After collection of material, flush area with water. Dispose of the material in accordance with standard practice for disposal of potentially hazardous materials as required by applicable federal, state or local laws.

Special Reporting Requirements:  Not applicable.

Handling and storage

Precautions for safe handling:

Precautions for Unique Hazards:  Not applicable.

Practices to Minimize Risk:  Wear appropriate protective equipment when performing maintenance on contaminated equipment.  Wash hands thoroughly before eating or smoking after handling this material.  

Special Handling Equipment:  Not applicable.

Storage Precautions & Recommendations:       Maintain dry, ventilated conditions for storage. Protect containers against physical damage. Outside or detached storage is preferable. Inside storage should be in standard flammable liquids storage room or cabinet. Keep away from strong acids and oxidizing agents.  

Dangerous Incompatibility Reactions:  Avoid contact with strong acids and oxidizing agents.

Incompatibilities with Materials of Construction:  None known
