Potential Health Effects

----------------------------------

Inhalation:

Dust may cause irritation of the nose, throat, and lungs. Ammonia vapors released upon

decomposition may cause irritation of the upper respiratory tract, with coughing,

 

vomiting, and redness to the mucous membranes. Higher concentrations (> 1000 ppm) may

cause restlessness, tightness in the chest, pulmonary edema, weak pulse, and cyanosis.

Ingestion:

Large oral doses may cause irritation to the gastrointestinal tract.

Skin Contact:

May cause irritation with redness and pain.

Eye Contact:

May cause irritation, redness and pain.

Chronic Exposure:

No information found.

Aggravation of Pre-existing Conditions:

No information found.

. First Aid Measures

Inhalation:

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

difficult, give oxygen. Get medical attention.

Ingestion:

Give several glasses of water to drink to dilute. If large amounts were swallowed, get

medical advice.

Skin Contact:

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

contaminated clothing and shoes. Wash clothing before reuse. Thoroughly clean shoes

before reuse. Get medical attention if irritation develops.

Eye Contact:

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

lower eyelids occasionally. Get medical attention if irritation persists.

5

. Fire Fighting Measures

Fire:

Not considered to be a fire hazard. Irritating and toxic ammonia gas may form in fires.

Explosion:

Not considered to be an explosion hazard.

Fire Extinguishing Media:

Use any means suitable for extinguishing surrounding fire.

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.

6

. 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. US Regulations (CERCLA)

require reporting spills and releases to soil, water and air in excess of reportable

quantities. The toll free number for the US Coast Guard National Response Center is (800)

24-8802.

7

. Handling and Storage

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

physical damage. Store at temperatures below 80F (27C) to minimize decomposition.

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.

8

. 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 protective gloves and clean body-covering clothing.

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.
