Potential Health Effects

———————————-

Inhalation:

Causes irritation to the respiratory tract. Symptoms may include coughing,

shortness of breath.

Ingestion:

Causes irritation to the gastrointestinal tract. Symptoms may include

nausea, vomiting and diarrhea. Extremely large oral dosages may produce

gastrointestinal disturbances. Calcium deficiency in blood may result in

severe cases of ingestion.

Skin Contact:

Causes irritation to skin. Symptoms include redness, itching, and pain.

Eye Contact:

Highly irritating; may also be abrasive.

Chronic Exposure:

Chronic or heavy acute ingestion may cause tooth enamel erosion.

Aggravation of Pre-existing Conditions:

No adverse health effects expected.

  1. First Aid Measures

Inhalation:

Remove to fresh air. If not breathing, give artificial respiration. If

breathing is difficult, give oxygen. Get medical attention.

Ingestion:

Induce vomiting immediately as directed by medical personnel. Never

give anything by mouth to an unconscious person.

Skin Contact:

Immediately flush skin with plenty of water for at least 15 minutes.

 

Remove contaminated clothing and shoes. Get medical attention. Wash

clothing before reuse. Thoroughly clean shoes before reuse.

Eye Contact:

Immediately flush eyes with plenty of water for at least 15 minutes, lifting

lower and upper eyelids occasionally. Get medical attention immediately.

  1. Fire Fighting Measures

Fire:

Autoignition temperature: 1011C (1852F)

As with most organic solids, fire is possible at elevated temperatures or by

contact with an ignition source.

Explosion:

Fine dust dispersed in air in sufficient concentrations, and in the presence

of an ignition source is a potential dust explosion hazard.

Fire Extinguishing Media:

Water spray, dry chemical, alcohol foam, or carbon dioxide.

Special Information:

In the event of a fire, wear full protective clothing and NIOSH-approved

self-contained breathing apparatus with full facepiece operated in the

pressure demand or other positive pressure mode.

  1. Accidental Release Measures

Ventilate area of leak or spill. Wear appropriate personal protective

equipment as specified in Section 8. Spills: Sweep up and containerize for

reclamation or disposal. Vacuuming or wet sweeping may be used to

avoid dust dispersal.

  1. Handling and Storage

Keep in a tightly closed container, stored in a cool, dry, ventilated area.

Protect against physical damage. Containers of this material may be

hazardous when empty since they retain product residues (dust, solids);

observe all warnings and precautions listed for the product.

  1. Exposure Controls/Personal Protection

Airborne Exposure Limits:

None established.

Ventilation System:

 

A system of local and/or general exhaust is recommended to keep

employee exposures as low as possible. Local exhaust ventilation is

generally preferred because it can control the emissions of the contaminant

at its source, preventing dispersion of it into the general work area. Please

refer to the ACGIH document, Industrial Ventilation, A Manual of

Recommended Practices, most recent edition, for details.

Personal Respirators (NIOSH Approved):

For conditions of use where exposure to dust or mist is apparent and

engineering controls are not feasible, a particulate respirator (NIOSH type

N95 or better filters) may be worn. If oil particles (e.g. lubricants, cutting

fluids, glycerine, etc.) are present, use a NIOSH type R or P filter. For

emergencies or instances where the exposure levels are not known, use a

full-face positive-pressure, air-supplied respirator. WARNING: Air-

purifying respirators do not protect workers in oxygen-deficient

atmospheres.

Skin Protection:

Wear impervious protective clothing, including boots, gloves, lab coat,

apron or coveralls, as appropriate, to prevent skin contact.

Eye Protection:

Use chemical safety goggles and/or full face shield where dusting or

splashing of solutions is possible. Maintain eye wash fountain and quick-

drench facilities in work area.
