Medical Conditions
Aggravated by
Overexposure:
Repeated or prolonged contact with spray mist may produce chronic eye irritation and severe
skin irritation. Repeated or prolonged exposure to spray mist may produce respiratory tract
irritation leading to frequent attacks of bronchial infection. Repeated exposure to a highly toxic
material may produce general deterioration of health by an accumulation in one or many
human organs.
Carcinogenic Effects Classified 3 by IARC(Fast Green FCF)
Additional information See Toxicological Information (section 11)
If swallowed, do not induce vomiting unless directed to do so by medical personnel. Never give
anything by mouth to an unconscious person. Loosen tight clothing such as a collar, tie, belt or
waistband. Get medical attention immediately.
Check for and remove any contact lenses. In case of contact, immediately flush eyes with
plenty of water for at least 15 minutes. Cold water may be used. Get medical attention
immediately.
In case of contact, immediately flush skin with plenty of water for at least 15 minutes while
removing contaminated clothing and shoes. Cover the irritated skin with an emollient. Cold
water may be used. Wash clothing before reuse. Thoroughly clean shoes before reuse. Get
medical attention immediately.
If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult,
give oxygen. Get medical attention immediately.

Section 6. Accidental Release Measures
Dilute with water and mop up, or absorb with an inert dry material and place in an appropriate
waste disposal container. If necessary: Neutralize the residue with a dilute solution of
sodium carbonate.
Stop leak if without risk. Absorb with DRY earth, sand or other non-combustible material. Do
not get water inside container. Do not touch spilled material. Use water spray curtain to divert
vapor drift. Use water spray to reduce vapors. Prevent entry into sewers, basements or
confined areas; dike if needed. Call for assistance on disposal. Neutralize the residue with a
dilute solution of sodium carbonate. Be careful that the product is not present at a
concentration level above TLV. Check TLV on the MSDS and with local authorities.
Small Spill and Leak
Large Spill and Leak
Spill Kit Information The following EMD Chemicals Inc. SpillSolv (TM) absorbent is recommended for this product:
SX1310 Acid Treatment Kit
Keep container tightly closed. Keep container in a cool, well-ventilated area. Store between
15 to 30°C (59 to 86°F).
Avoid contact with eyes, skin and clothing. Do not ingest. Avoid breathing vapors or spray
mists. Use only with adequate ventilation. Wash thoroughly after handling.
Section 7. Handling and Storage
Handling
Storage
Provide exhaust ventilation or other engineering controls to keep the airborne concentrations of
vapors below their respective occupational exposure limits. Ensure that eyewash stations and
safety showers are proximal to the work-station location.
Splash goggles. Full suit. Vapor respirator. Boots. Gloves. A self-contained breathing
apparatus should be used to avoid inhalation of the product. Suggested protective clothing
might not be sufficient; consult a specialist BEFORE handling this product.
