Section 4: First-Aid Measures

Emergency and First Aid Procedures:

Individuals with a hypersensitive response to EDTA may be more susceptible to exposure effects.  If symptoms persist, call a physician.

If in eyes:

Immediately flush eyes with plenty of water for at least 15 minutes while holding lids gently but firmly apart. Lift upper and lower lids occasionally to ensure thorough flushing. Obtain medical attention.

If on skin or clothing:

Flood area with water for at least 15 minutes. Remove contaminated clothing and shoes. Wash clothing and clean shoes thoroughly before reuse. Get medical attention immediately if symptoms occur.

If inhaled:

Remove person to fresh air. If breathing is difficult, give oxygen. Get medical attention immediately if symptoms occur.

If swallowed:

Never give anything by mouth to an unconscious person. Do not induce vomiting. Obtain medical care.

       

 

Section 5: Fire-Fighting Measures

Flash Point:

N/A

Flammability:

Not flammable. Keep product and container away from heat and sources of ignition.

Products of combustion:

Material will not burn until water has been evaporated. Container may rupture on heating. Incomplete combustion may form carbon monoxide.

Extinguishing Media:

Use water-spray, dry chemical, alcohol foam, or CO2. Tailor extinguishing media to surrounding fire. Use water spray to cool unopened containers.

Protective equipment and precautions for firefighters:

Wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full facepiece operated in the pressure demand or other positive pressure mode.

 

Section 6:  Accidental Release Measures

Personal precautions:

Keep unnecessary personnel away. Local authorities should be advised if significant spillages cannot be contained. Wear appropriate protective equipment and clothing during clean up. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Keep people away from and upwind of spill/leak. Ensure adequate ventilation. Avoid inhalation of dust from the spilled material.

Environmental Precautions:

Contact local authorities in case of spillage to drain/aquatic environment. Avoid discharge into drains, water courses, or onto the ground. Prevent further leakage or spillage if safe to do so. Do not contaminate water.

Containment and cleanup:

Ventilate area. Wear protective clothing. Use an absorbent material such as sand, sawdust, or vermiculite to absorb small spills or any leakage that cannot be recovered for recycling. Wash area thoroughly with water after recovering released material. Avoid dust formation. Minimize dust generation and accumulation. For waste disposal, see section 13 of the SDS.

 

Section 7:  Handling and Storage

Safe handling:

Wear personal protective equipment. Ensure adequate ventilation. Avoid contact with skin, eyes, and clothing. Avoid ingestion and inhalation. Avoid dust formation.

Safe storage:

Store bottles tightly capped and upright. Keep in a cool place away from direct sunlight.
