First aid procedures

Eye contact Immediately flush eyes with plenty of water for at least 15 minutes. Get medical attention

immediately.

Skin contact For skin contact flush with large amounts of water. Get medical attention if irritation develops or

persists. Immediately take off all contaminated clothing. Wash clothing separately before reuse.

Inhalation If symptoms are experienced, remove source of contamination or move victim to fresh air. If

symptoms persist, get medical attention. If the affected person is not breathing, apply artificial

respiration. If breathing is difficult, give oxygen. Get medical attention immediately.

Ingestion If material is ingested, immediately contact a physician or poison control center. Do NOT induce

vomiting.

Protection of firefighters

Protective equipment and

precautions for firefighters

As in any fire, wear self-contained breathing apparatus pressure-demand, MSHA/NIOSH

(approved or equivalent) and full protective gear.

6. Accidental Release Measures

Personal precautions Keep unnecessary personnel away. Keep upwind. Keep out of low areas. Keep people away from

and upwind of spill/leak. Ventilate closed spaces before entering them. Do not touch damaged

containers or spilled material unless wearing appropriate protective clothing.

Environmental precautions Prevent further leakage or spillage if safe to do so. Do not contaminate water.

Methods for containment ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area). Stop the

flow of material, if this is without risk. Dike the spilled material, where this is possible. Prevent

entry into waterways, sewer, basements or confined areas.

Methods for cleaning up Should not be released into the environment.

Large Spills: Dike far ahead of spill for later disposal.

Small Spills: Wipe up with absorbent material (e.g. cloth, fleece). Clean surface thoroughly to

remove residual contamination. Following product recovery, flush area with water.

Never return spills in original containers for re-use.

7. Handling and Storage

Handling Avoid contact with skin and eyes. Wash hands thoroughly after handling. All equipment used

when handling the product must be grounded. DO NOT handle, store or open near an open flame,

sources of heat or sources of ignition. Protect material from direct sunlight.

Storage Keep away from heat, sparks and open flame. Prevent electrostatic charge build-up by using

common bonding and grounding techniques. Store in cool place. Store in a well-ventilated place.

Store in a closed container away from incompatible materials.
