  1. Hazardous Identification

Emergency Overview

WARNING MAY BE HARMFUL IF SWALLOWED OR INHALED. MAY CAUSE

IRRITATION TO SKIN AND RESPIRATORY TRACT. CAUSES EYE IRRITATION.

Health Rating: 1-Slight

Flammability: 1-Slight

Reactivity Rating: 0-None

Contact Rating: 1-Slight

Lab Protective Equip: GOGGLES, LAB COAT

Storage Color Code: Orange(General Storage)

Potential Health Effects:

There is insufficient data in the published literature to perform a complete

hazard evaluation for this product. Special precautions must be used in

storage, use and handling. Protective equipment should be chosen using

professional judgment.

Inhalation

Mild irritant. Symptoms may include coughing on sneezing. May cause

irritation to the respiratory tract.

Ingestion:

Substance has low toxicity by ingestion. Large amount may cause gastric

upset due to osmotic imbalance through the sequestering of metal ions.

Skin Contact:

Mild irritant. Symptoms may include reddening or inflammation on

prolonged contact.

Eye Contact:

Causes irritation. Solutions are severe irritants to the eye and cause pain,

blurred vision.

Chronic Exposure:

No information found.

Aggravation of Pre-existing Conditions:

No information found.

 

  1. First Aid Measures

Inhalation:

If inhaled, remove to fresh air. If not, breathing, give artificial respiration. If

breathing is difficult, give oxygen. Call a physician.

Skin Contact:

Remove any contaminated clothing. Wash skin with soap or mild detergent

and water for at least 15 minutes. Get medical attention if irritation

develops or persists. Wash clothing before re-use.

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:

Not considered to be a fire hazard.

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-face piece 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: Pick up and place in a suitable

container for reclamation or disposal, using a method that does not

generate dust.

 

  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.

 

8.Exposure Control/Personal Protection

Airborne Exposure Limits.

-OSHA Permissible Exposure Limit (PEL);

15mg/m3 total dust, 5mg/m3 respirable fraction for nuisance dust;

-ACGITI Threshold Limit Value (TLV);

10mg/m3 total dust containing no asbestos and <1% crystalline silica for

Particulates Not Otherwise Classified (PNOC).

Ventilation System:

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

employee exposures below the Airborne Exposure Limits. Local exhaust

ventilation is generally pretaned 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)

If the exposure limit is exceeded and engineering controls are not feasible,

a half face-piece particulate respirator (NIOSH type N95 or better filter) may

be worn for up to ten times the exposure limit or the maximum use

concentration specified by the appropriate regulatory agency or respirator

supplier, whichever is lowest. A full-face piece particulate respirator (NIOSH

type N100 filters) may be worn up to 50 times the exposure limit, or the

maximum use concentration specified consignments of instances where the

exposure levels are not known, use a full-face piece 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 safely goggles. Maintain eye wash fountain and quick-drench

facilities in work area.
