2-pyridylamine

Guidance on Safe Use

First-aid measures

Eyes: If in eyes rinse cautiously with water for at least 15 minutes. Remove contact lenses if easy to do so. Continue rinsing. Seek immediate medical

attention.

Skin: Immediately take off all contaminated clothing. Wash thoroughly with water for at least 15 minutes. Seek  medical attention.

Inhalation: Remove to fresh air and keep at rest in a position comfortable for breathing. Monitor for respiratory distress. Apply artificial respiration ifnot breathing. Do not use mouth-to-mouth methods if victim ingested or inhaled the substance; give artificial respiration with the aid of a pocket

mask equipped with a one-way valve or other proper respiratory medical device.

Ingestion: If swallowed rinse mouth. Do NOT induce vomiting by use of emetics. Seek medical attention, call a poison center if you feel unwell.

Fire-fighting measures

Fire Fighting Procedures:

Extinguishant: Carbon dioxide, dry chemical, alcohol foam

If material on fire or involved in fire: Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with

difficulty.) Use water in flooding quantities as fog. Use foam, dry chemical, or carbon dioxide. Keep run-off water out of sewers and water sources.

Accidental release measures

Exposure Control and emergency control :

Wear protective clothing, full boots, impervious gloves, safety glasses and Self Contained Breathing Apparatus. Alert Emergency Responders and tell them location and nature of hazard. Shut off all possible sources of ignition and increase ventilation. Avoid breathing vapors and contact with skin

and eyes.

Environmental precautions:

Clean up all spills immediately and prevent, by spillage from entering drains or water and watercourses. Inform authorities in event of contamination of any  public sewers, drains or water bodies.

Clean up methods:

Collect recoverable product into labeled containers for recycling, recovery or disposal. Spread area with lime or absorbent material, and leave for at

least 1  hour before washing.

Handling and storage

In general materials which are toxic as stored or which can decompose into toxic components should be stored in cool, well- ventilated place out of sun, away from areas of high fire hazard and should be periodically inspected & monitored. Incompatible materials should be isolated.

Exposure controls / personal protection

WEL 8hr TWA  : 0.5 (ppm)       

STEL: 2.0 ppm

NIOSH: 0.5 ppm TWA, 2 mg/m3 TWA 5 ppm IDLH       

ACGIH: 0.5 ppm TWA       

OSHA - Final PELs:  0.5 ppm TWA; 2 mg/m3 TWA

Engineering Controls

Provide exhaust ventilation or other engineering controls to keep the relevant airborne concentrations below their respective occupational exposure limits. Local ventilation is usually preferred. Ensure that eyewash stations and safety showers are close to the workstation location.

Personal Protection

Protective clothing should be selected specifically for the working place, depending on concentration and quantity of the hazardous substances

handled. The resistance of the protective clothing to chemicals should be ascertained with the respective supplier.

Hands: Wear appropriate protective gloves to prevent skin exposure or as described below.

Stability and reactivity

Reactivity

2-Aminopyridine is white leaflets or large colorless crystals like odor Characteristic- similar to pyridine. It is Soluble in water, alcohol, benzene, ether, hot petrol ether, acetone and organic solvents; slightly soluble in chloroform.

Chemical stability

Oxidizes and darkens with time. Heat and light accelerate this process.

Hazardous Polymerization will not occur.

Conditions to avoid

Keep away from heat, sparks, flame, high temperature and incompatible chemicals.

Incompatible materials       

Strong oxidizing agents.

Hazardous decomposition products

Thermal decomposition may produce carbon monoxide and oxides of nitrogen, carbon dioxide & nitrogen and irritating and toxic fumes.

Disposal considerations

Dispose of this material in accordance with standard practice for disposal of potentially hazardous materials as required by applicable federal, state or local laws. Note that disposal regulations may also apply to empty containers and equipment rinsates.

2-Aminopyridine may be disposed of: 1. By making packages of 2-aminopyridine in paper or other flammable material and burning in a suitable

combustion chamber equipped with an appropriate effluent gas cleaning device.
