for at least 15 minutes, occasionally lifting the upper and lower eyelids. 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. Wash clothing before reuse. Clean
shoes thoroughly before reuse. Get medical attention immediately.
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.

Flux-Off® No Clean New and Improved
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.
No specific treatment. Treat symptomatically. Contact poison treatment specialist
immediately if large quantities have been ingested or inhaled.
Protection of first-aiders
No action shall be taken involving any personal risk or without suitable training. It may
be dangerous to the person providing aid to give mouth-to-mouth resuscitation.
Use an extinguishing agent suitable for the surrounding fire.
5. Fire-fighting measures
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.
In a fire or if heated, a pressure increase will occur and the container may burst.
Special protective
equipment for fire-fighters
Fire-fighters should wear appropriate protective equipment and self-contained breathing
apparatus (SCBA) with a full face-piece operated in positive pressure mode.
Hazardous thermal
decomposition products
Decomposition products may include the following materials:
carbon dioxide
carbon monoxide
halogenated compounds
carbonyl halides
Flammability of the product
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. Avoid breathing vapor or mist.
Provide adequate ventilation. Wear appropriate respirator when ventilation is
inadequate. Put on appropriate personal protective equipment (see Section 8).
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). 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.
Environmental precautions
6. Accidental release measures
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).
Stop leak if without risk. Move containers from spill area. Dilute with water and mop up
if water-soluble. Alternatively, or if water-insoluble, absorb with an inert dry material and
place in an appropriate waste disposal container. Dispose of via a licensed waste
disposal contractor.

Flux-Off® No Clean New and Improved
Store in accordance with local regulations. 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. Do not puncture, incinerate or store the container
at temperatures above 49°C (120°F) or in direct sunlight.
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.
If during normal use the material presents a respiratory hazard, use only with adequate
ventilation or wear appropriate respirator. Empty containers retain product residue and
can be hazardous. Do not puncture or incinerate container. Store below 120°F (49°C).

8. Exposure controls/personal protection

Flux-Off® No Clean New and Improved
8. Exposure controls/personal protection
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.
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 or
dusts. If contact is possible, the following protection should be worn, unless the
assessment indicates a higher degree of protection: chemical splash goggles.
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.
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. Considering the parameters specified by the glove manufacturer, check
during use that the gloves are still retaining their protective properties. It should be
noted that the time to breakthrough for any glove material may be different for different
glove manufacturers. In the case of mixtures, consisting of several substances, the
protection time of the gloves cannot be accurately estimated.
Good general ventilation should be sufficient to control worker exposure to airborne
contaminants.
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.
Recommended monitoring
procedures
If this product contains ingredients with exposure limits, personal, workplace
atmosphere or biological monitoring may be required to determine the effectiveness of
the ventilation or other control measures and/or the necessity to use respiratory
protective equipment. Reference should be made to appropriate monitoring standards.
Reference to national guidance documents for methods for the determination of
hazardous substances will also be required.
Environmental exposure
controls
Emissions from ventilation or work process equipment should be checked to ensure
they comply with the requirements of environmental protection legislation.

requirements of environmental protection and waste disposal legislation and any
regional local authority requirements. Dispose of surplus and non-recyclable products
via a licensed waste disposal contractor. Waste should not be disposed of untreated to
the sewer unless fully compliant with the requirements of all authorities with jurisdiction.
Waste packaging should be recycled. Incineration or landfill should only be considered
when recycling is not feasible. This material and its container must be disposed of in a
safe way. Care should be taken when handling emptied containers that have not been
cleaned or rinsed out. Empty containers or liners may retain some product residues.
