Section 4. First Aid Measures
Eye Contact 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.
Skin Contact 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.
Serious Skin Contact Wash with a disinfectant soap and cover the contaminated skin with an anti-bacterial cream. Seek
immediate medical attention.
Inhalation If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
Get medical attention.
Serious Inhalation Evacuate the victim to a safe area as soon as possible. Loosen tight clothing such as a collar, tie, belt or
waistband. If breathing is difficult, administer oxygen. If the victim is not breathing, perform mouth-to-mouth
resuscitation. WARNING: It may be hazardous to the person providing aid to give mouth-to-mouth
resuscitation when the inhaled material is toxic, infectious or corrosive. Seek immediate medical attention.
Ingestion Do NOT induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to
an unconscious person. If large quantities of this material are swallowed, call a physician immediately.
Loosen tight clothing such as a collar, tie, belt or waistband.
Serious Ingestion Not available.

Section 6. Accidental Release Measures
Small Spill Dilute with water and mop up, or absorb with an inert dry material and place in an appropriate waste
disposal container.
Large Spill Combustible material. Corrosive liquid.
Keep away from heat. Keep away from sources of ignition. 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. Prevent entry into sewers, basements or confined
Crotonic acid
Section 7. Handling and Storage
Precautions Keep container dry. Keep away from heat. Keep away from sources of ignition. Ground all equipment
containing material. Do not ingest. Do not breathe gas/fumes/ vapor/spray. Never add water to this
product. In case of insufficient ventilation, wear suitable respiratory equipment. If ingested, seek medical
advice immediately and show the container or the label. Avoid contact with skin and eyes. Keep away from
incompatibles such as oxidizing agents.
Storage Keep container in a cool, well-ventilated area. Keep container tightly closed and sealed until ready for use.
Avoid all possible sources of ignition (spark or flame).
Section 8. Exposure Controls/Personal Protection
Engineering Controls Provide exhaust ventilation or other engineering controls to keep the airborne concentrations of vapors
below their respective threshold limit value. Ensure that eyewash stations and safety showers are proximal
to the work-station location.
Personal Protection Face shield. Full suit. Vapor respirator. Be sure to use an approved/certified respirator or equivalent.
Gloves. Boots. Respiratory protection is not necessary for normal handling. Good room ventilation or use
of local exhaust (fume hood) is sufficient. Use a vapor respirator under conditions where exposure to the
substance is apparent (e.g. generation of high concentrations of mist or vapor or dust, inadequate
ventilation, development of respiratory tract irritation), and engineering controls are not feasible. Be sure to
use an approved/certified respirator or equivalent.
Personal Protection in Case of Splash goggles. Full suit. Vapor respirator. Boots. Gloves. A self contained breathing apparatus should
a Large Spill be used to avoid inhalation of the product. Suggested protective clothing might not be sufficient; consult a
specialist BEFORE handling this product.
