*Note Disclaimer of Warranty on back page*

B - PHYSIOLOGICAL EFFECTS

Eye: Human experience indicates that Sodium Propionate is not an eye irritant.

Skin: Human experience indicates that Sodium Propionate is not a skin irritant.

Systemic: There are no known physiological problems associated with normal handling of Sodium Propionate

No information is available concerning potential long-term health effects.

C - EMERGENCY AND FIRST AID PROCEDURES

Eye Contact: Flush eyes gently with copious quantities of water for a minimum of fifteen minutes. Use fingers to assure that eyelids are separated and that eye is being irrigated. Contact supervision.

Skin Contact: Wash thoroughly with soap and water.

Inhalation: Remove from source of exposure. Contact supervision.

D - SPECIAL PROTECTION INFORMATION

Eye Protection: Safety glasses with the side shields and/or chemical safety goggles should be worn in dusty environments. The choice of protection should be appropriate to the task being performed.

Respiratory Protection: OSHA and ACGIH have not established specific exposure limits for Sodium Propionate; they have established limits for nuisance dusts.

OSHA - PEL/TWA: Total 15 mg/M³; Respirable 5 mg/M³

ACGIH - TLV/TWA Total 10mg/M³ ; Respirable 5 mg/M³

Process containment and/or local exhaust ventilation should be used to minimize Sodium Propionate dust. If respiratory protection is needed for high dust levels, an appropriate, properly fitted NIOSH/NSHA approved, full-face mask with dust mist cartridge may be used. The choice of protection should be appropriate to the existing conditions.

Skin Protection: In the manufacture of Sodium Propionate, refer to the batch sheets.

Ventilation: Local exhaust ventilation may be used to minimize Sodium Propionate dust.

Other: Washing facilities should be available.

Wash thoroughly after handling.

E - FIRE PROTECTION INFORMATION

Flash Point (Test Method): None

LEL (Lower Explosion Limit): None

UEL (Upper Explosion Limit): Information not available. Avoid dusting, as all organic dusts can be explosive under certain conditions.

Extinguishing Media: Water, carbon dioxide, dry chemical extinguisher, foam.

Special Fire Fighting Procedures: Full protective equipment including NIOSH/MSHA approved positive pressure self-contained breathing apparatus should be worn. All protective equipment should be cleaned thoroughly after use.

F - REACTIVITY DATA

Stability (Thermal, Light, Etc.): Material is very hygroscopic.

Incompatibility (Materials to Avoid): Information not available.

Hazardous Decomposition Combustion may produce carbon dioxide and Carbon monoxide.

Hazardous Polymerization: Will not occur.

G - ENVIRONMENTAL PROTECTION

Environmental Impact: All waste residuals should be handled under the prevailing local and federal guidelines/regulations for control and disposal of such chemical wastes.

Precautions if Material is Released

or Spilled: If spill occurs, sweep or shovel material into

waste containers. An appropriate industrial

vacuum cleaner equipped with high efficiency

particulate filters for dusts may also be used.

Waste Disposal Methods: Dispose of any residues or wastes according to prescribed statutes, regulations and guidelines, e.g., secured chemical landfill disposal, approved chemical wastes incineration or approved (low level) discharges to municipal or on-site waste-water treatment facilities.

H - SPECIAL PRECAUTIONS AND NOTES

Storage: Containers should be kept closed and free from moisture.

NOTE: Due to the hygroscopic characteristics, dusting should be controlled to prevent surfaces from becoming very slippery.
