Hazard statementHarmful to aquatic life
Toxic to aquatic organisms due to long-term continuous effects
Precautionary statement
Safety measure
Avoid release to the environment.
First Aid Measures
Collect the leaked material.
Disposal
Discard contents/containers according to international/national/prefectural/municipal
regulations.
Other hazards not related to GHS classification or not covered by GHS
Hazardous property
If you get into your eyes, it is irritating.
Skin contact may cause inflammation.

４．FIRST－AID MEASURES
If inhaled
Remove person to fresh air and keep comfortable for breathing.
Get medical advice/attention if you feel unwell.
If on skin
Immediately remove contaminated clothing, shoes, etc.
Wash the contact area thoroughly with running water and soap.
If skin irritation occurs, get medical advice/attention.
If in eyes
Rinse immediately and carefully with water for several minutes.
Next, if you are wearing contact lenses and can easily remove them, remove them.
Continue cleaning after that.
Receive immediate care from an ophthalmologist.
If swallowed
Clean the mouth with water and drink 1 to 2 cups of water.

５．FIRE－FIGHTING MEASURESExtinguishing MediaSuitable extinguishing media
Water (spraying/fogging), foam extinguishing agents, powder, carbon dioxide, etc.
Extinguishing agent that must not be used
Spray water may be used for cooling purposes, but rod water should not be used forextinction.
Specific hazards of fire
Product dry matter generates black smoke, carbon monoxide, and other noxious gases
due to thermal decomposition and incomplete
Fire fighting measures
If the dried product is ignited, use a general fire extinguishing agent such as waterinjection, water spray, dry chemicals, etc., and extinguish the fire from the windwardside.
Specific protective equipment and precautions for those performing firefighting activities
Wear appropriate protective equipment and protective clothing (self-contained breathingapparatus, heat-resistant protective clothing, etc.).
６．ACCIDENTAL RELEASE MEASURES
Precautions, Protective Equipment, and Emergency Measures for the Human Body
Avoid direct contact with the skin as much as possible, and wear protective gloves (rubberor resin), protective glasses (glass or resin goggles type), and boots (rubber).
Environmental precautions
Latex causes widespread white turbidity even in small amounts when it enters rivers,
lakes, etc.
Avoid spills into public water bodies and sewage, such as streams, lakes, and marshes,and releases into the environment.
If it has flowed in, or if you are taking in drinking water from the inflowing river, ask
them to stop taking water until it runs out.
Methods and equipment for containment and purification
When a small amount is used, it is absorbed into an inert absorbent such as dried sand,sawdust, or the like, and recovered.
In the case of a large amount, first, prevent diffusion with sandbags or surrounding earthand sand, and then agglomerate and solidify with calcium chloride to recover.
〈Reference: Methods of coagulation with calcium chloride.〉
Make about 10% calcium chloride aqueous solution, sprinkle over the leaked latex andstir.
Small amounts of spraying may not aggregate. If this is the case, increase the amount ofspraying.
In the case of urgency, even if calcium chloride is sprayed as a solid, it can be coagulated
and solidified.
Prevention of secondary hazards
No information
７．HANDLING AND STORAGE
Handling
Technical measures
Do not leak from the container and wear protective gloves and spectacles.
Local and general ventilation
If there is a risk of steam, mist, or dust generation, install appropriate disposal /ventilation equipment such as a local exhaust system.
Precautions
Efforts should be made to organize the workplace, and the fire should not beapproached.
