Section 4. First aid measures
Eye contact : Check for and remove any contact lenses. Immediately flush eyes with plenty of water
for at least 15 minutes, occasionally lifting the upper and lower eyelids. 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. Wash clothing before reuse. Clean
shoes thoroughly before reuse. Get medical attention immediately.
Inhalation : Move exposed person to fresh air. If not breathing, if breathing is irregular or if
respiratory arrest occurs, provide artificial respiration or oxygen by trained personnel.
Loosen tight clothing such as a collar, tie, belt or waistband. Get medical attention
immediately.
Ingestion : Wash out mouth with water. Do not induce vomiting unless directed to do so by medical
personnel. Never give anything by mouth to an unconscious person. Get medical
attention immediately.
Section 5. Fire fighting measures
Flammability of the product : May be combustible at high temperature.
Auto-ignition temperature : Lowest known value: 219.85癈 (427.7癋) (octane).
Flash point : Lowest known value: Closed cup: -50.15癈 (-58.3癋). (pentane)
Flammable limits : Greatest known range: Lower: 1.5% Upper: 7.8% (pentane)
Products of combustion : Decomposition products may include the following materials:
carbon dioxide
carbon monoxide
Extinguishing media
Suitable : Use dry chemical, CO2, water spray (fog) or foam.
Not suitable : Do not use water jet.
Special exposure hazards : Promptly isolate the scene by removing all persons from the vicinity of the incident if
there is a fire. No action shall be taken involving any personal risk or without suitable
training. Move containers from fire area if this can be done without risk. Use water
spray to keep fire-exposed containers cool.
Extremely flammable liquid. In a fire or if heated, a pressure increase will occur and the
container may burst, with the risk of a subsequent explosion. Runoff to sewer may
create fire or explosion hazard.
Special protective : Fire-fighters should wear appropriate protective equipment and self-contained breathing
apparatus (SCBA) with a full face-piece operated in positive pressure mode.
equipment for fire-fighters
Section 6. Accidental release measures
Personal precautions : No action shall be taken involving any personal risk or without suitable training.
Evacuate surrounding areas. Keep unnecessary and unprotected personnel from
entering. Do not touch or walk through spilled material. Shut off all ignition sources. No
flares, smoking or flames in hazard area. Avoid breathing vapor or mist. Provide
adequate ventilation. Wear appropriate respirator when ventilation is inadequate. Put
on appropriate personal protective equipment (see section 8).
Environmental precautions : Avoid dispersal of spilled material and runoff and contact with soil, waterways, drains
and sewers. Inform the relevant authorities if the product has caused environmental
pollution (sewers, waterways, soil or air).
Methods for cleaning up : Stop leak if without risk. Move containers from spill area. Approach release from
upwind. Prevent entry into sewers, water courses, basements or confined areas. Wash
spillages into an effluent treatment plant or proceed as follows. Contain and collect
spillage with non-combustible, absorbent material e.g. sand, earth, vermiculite or
diatomaceous earth and place in container for disposal according to local regulations
(see section 13). Use spark-proof tools and explosion-proof equipment. Dispose of via
a licensed waste disposal contractor. Contaminated absorbent material may pose the
same hazard as the spilled product. Note: see section 1 for emergency contact
information and section 13 for waste disposal.

Section 7. Handling and storage
Handling : Put on appropriate personal protective equipment (see section 8). Eating, drinking and
smoking should be prohibited in areas where this material is handled, stored and
processed. Workers should wash hands and face before eating, drinking and smoking.
Do not get in eyes or on skin or clothing. Do not breathe vapor or mist. Do not ingest.
Use only with adequate ventilation. Wear appropriate respirator when ventilation is
inadequate. Do not enter storage areas and confined spaces unless adequately
ventilated. Keep in the original container or an approved alternative made from a
compatible material, kept tightly closed when not in use. Store and use away from heat,
sparks, open flame or any other ignition source. Use explosion-proof electrical
(ventilating, lighting and material handling) equipment. Use non-sparking tools. Take
precautionary measures against electrostatic discharges. To avoid fire or explosion,
dissipate static electricity during transfer by grounding and bonding containers and
equipment before transferring material. Empty containers retain product residue and
can be hazardous. Do not reuse container.
Storage : Store in accordance with local regulations. Store in a segregated and approved area.
Store in original container protected from direct sunlight in a dry, cool and well-ventilated
area, away from incompatible materials (see section 10) and food and drink. Eliminate
all ignition sources. Separate from oxidizing materials. Keep container tightly closed
and sealed until ready for use. Containers that have been opened must be carefully
resealed and kept upright to prevent leakage. Do not store in unlabeled containers. Use
appropriate containment to avoid environmental contamination.
Section 8. Exposure controls/personal protection
Recommended monitoring : If this product contains ingredients with exposure limits, personal, workplace atmosphere
or biological monitoring may be required to determine the effectiveness of the ventilation
procedures
or other control measures and/or the necessity to use respiratory protective equipment.
Engineering measures : Use only with adequate ventilation. Use process enclosures, local exhaust ventilation or
other engineering controls to keep worker exposure to airborne contaminants below any
recommended or statutory limits. The engineering controls also need to keep gas, vapor
or dust concentrations below any lower explosive limits. Use explosion-proof ventilation
equipment.
Hygiene measures : Wash hands, forearms and face thoroughly after handling chemical products, before
eating, smoking and using the lavatory and at the end of the working period. Appropriate
techniques should be used to remove potentially contaminated clothing. Wash
contaminated clothing before reusing. Ensure that eyewash stations and safety showers
are close to the workstation location.
Personal protection
Eyes : Safety eyewear complying with an approved standard should be used when a risk
assessment indicates this is necessary to avoid exposure to liquid splashes, mists,
gases or dusts.
Skin : Personal protective equipment for the body should be selected based on the task being
performed and the risks involved and should be approved by a specialist before handling
this product.
Respiratory : Use a properly fitted, air-purifying or air-fed respirator complying with an approved
standard if a risk assessment indicates this is necessary. Respirator selection must be
based on known or anticipated exposure levels, the hazards of the product and the safe
working limits of the selected respirator.
Hands : Chemical-resistant, impervious gloves complying with an approved standard should be
worn at all times when handling chemical products if a risk assessment indicates this is
necessary.
Personal protection in case : Full chemical-resistant suit and self-contained breathing apparatus should be worn only
by trained and authorized persons.
