Cetylpyridinium chloride

Guidance on Safe Use

First-aid measures

Skin contact:  Immediately flush with water for 15 minutes. Wash the contaminated skin with soap and water. If irritation develops, call a physician.

Eye Contact: Immediately flush the contaminated eye(s) with lukewarm, gently flowing water for 15 minutes, or until the chemical is removed. Neutral saline solution may be used as soon as it is available. Take care not to rinse contaminated water into the unaffected eye or onto face. If irritation persists, repeat flushing. Obtain medical  attention immediately.

Inhalation: Remove from exposure area to fresh air immediately. If breathing is difficult, oxygen may be beneficial if administered by trained personnel, preferably on a doctor's advice.

Ingestion: If swallowed, contact physician or poison control center immediately.

Fire-fighting measures

Extinguishing Media:  Water spray Foam, alcohol foam, carbon dioxide, dry chemical.

Hazardous Products of Combusion:

During a fire, irritating and toxic gases, fumes and vapors may be generated. Hydrogen chloride, Nitrogen oxides

Potential for Dust Explosion:

Cetylpyridinium Chloride (CPC) was tested for dust explosion characteristics and the following results were obtained:

-       minimum ignition energy (MIE): 5 - 10 mJ

-       Explosion severity - 20L Sphere

-       Maximum explosion pressure (bar): 8.5

-       Maximum rate of pressure rise (bar/s): 682

-       Kst value (bar.m/s): 185

The MIE data suggests a high sensitivity to ignition.

Special Flammability Hazards:

Material may burn, but does not ignite readily. Avoid high temperature.  This product is an organic solid. As such, in its finely divided form, this product has the potential to present a dust explosion hazard under certain conditions. Please review the dust explosion data enclosed in this section. Handle this product in a manner that prevents dust generation and accumulation, and refer to National Fire Protection Association (NFPA) Standard 654 for further information on prevention of dust explosions.

Accidental release measures

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 in Section 4. Leather shoes that have been saturated must be discarded. CPC is extremely irritating to eyes and causes eye damage. Take all precautions needed to avoid eye contact and skin contact.

Environmental precautions:  Prevent releases to soils, sewers and waterways.

Methods and Materials for containment and cleaning up:  Avoid raising dust. Scrub area with detergent and water. Carefully scoop up and place into appropriate disposal container. Do not allow material to enter drains or water courses.  Notify appropriate authorities if required by regulation.

Handling and storage

Precautions for unique hazards:  This material may present a dust explosion hazard in solid form and is sensitive to ignition by electrostatic discharge. Maintain areas below flammable vapor / explosive dust concentrations.

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:  Minimize dust generation and accumulation.  Remove contaminated clothing and wash before reuse.

Storage precautions and recommendations:  Do not store in direct sunlight. Store in a cool dry place.  Keep container closed when not in use.

Dangerous incompatibility reactions:  strong oxidising agents, strong acids, acid anhydrides and acid chlorides.

Special provisions / remarks

Remarks:

Independent laboratory test results for particle size indicate that CPC does not meet the requirements in 49 CFR 173.132(b)(3)(iii) for a solid substance that is considered a dust. Therefore, acute inhalation data (determined as a dust) is not applicable for determining transportation class. The same requirements apply for international air [2.6.1(c)], maritime [2.6.2.1.3] and ADR (European Agreement concerning the international Carriage of Dangerous Goods [2.2.61.1.3]) transport regulations.

Exposure controls / personal protection

Personal protective equipment:  An approved chemical cartridge respirator or supplied-air breathing equipment should be used as conditions necessitate. Contact lenses should not be worn when handling this material. Do not smoke or eat in areas where this material is handled. Wear chemical protective gloves (EN374) and body- covering clothing to prevent skin exposure (gloves, apron and boots). Wear chemical goggles (EN166). Wear a face-shield when necessary to prevent contact with skin and eyes.

Respirator caution: Observe regulations for respirator use (APF of 10) . Air-purifying respirators must not be used in oxygen-deficient atmospheres.

Ventilation: All operations should be conducted in well-ventilated conditions. Local exhaust ventilation should be provided. Facilities storing or using this material should be equipped with an eyewash and safety shower. Ventilation should effectively remove and prevent buildup of any dust generated from the handling of this product.

Other engineering controls: All appropriate engineering controls should be used to minimize exposure potential. Use exhaust ventilation to keep airborne concentrations below exposure limits.

Stability and reactivity

Reactivity:  not classified as dangerously reactive

Chemical stability:  stable under normal conditions

Possiblility of hazardous reactions:  not expected to occur.

Conditions to avoid:  avoid contact with incompatible materials, dust generation and sources of heat.

Incompabile materials:  strong oxidising agents, strong acids, acid anhydrides, acid chlorides.

Hazardous decomposition products:  hydrogen chloride, nitrogen-containing gases, carbon monoxide

Disposal considerations

Dispose of this material in accordance with standard practice for disposal of potentially hazardous

materials as required by applicable international, national, regional, state or local laws. Do NOT dump into any sewers, on the ground, or into any body of water. For disposal within the EC, the appropriate code according to the European Waste Catalogue (EWC) should be used. Note that disposal regulations may also apply to empty containers and equipment rinsates.
