ThreeBond 2706 degreaser: safety data sheet highlights and line management requirements

This is a highly hazardous cleaning agent. The manufacturer’s safety data sheet classifies it as Carcinogenicity Category 1A and Reproductive toxicity Category 1A, with the signal word “Danger.” Before adopting it, confirm that your plant’s work environment, ventilation, protective equipment and health management measures meet the requirements of this hazard level. This page is a summary and cannot replace the full safety data sheet; the line must keep the manufacturer’s full SDS available for workers to consult at any time.

Many people use degreaser sprays as “a stronger cleaner”: put on cotton gloves, switch on a fan and spray. Not this product. Its hazard classification is not at the irritant level but at the level of long-term health hazards, and the line management requirements are completely different.

4. Composition

One point that’s easy to misread: the SDS’s table of labeled substances lists “Hexane (including alkyl isomers) 60–70%,” which looks as if n-hexane makes up 60 to 70%. It does not. That row totals all hexane isomers, mainly the 2-methylpentane (isohexane) in the first row of the table above. The actual n-hexane (CAS 110-54-3) content is ≤10%, with a measured value of 2.6% reported under PRTR. The distinction matters: n-hexane is a peripheral neurotoxin listed as a hazardous substance that can be absorbed through the skin, and its isomers have different toxicological properties. Don’t confuse the two when citing composition data.

The SDS also states that under Japanese regulations n-hexane is listed as a chemical substance causing skin disorders that must be handled with impermeable protective equipment (Ordinance on Industrial Safety and Health, Article 594-2, Paragraph 1), and is a priority assessment chemical substance under the Chemical Substances Control Law.

5. Precautionary statements (manufacturer P codes)

• P201 / P202: obtain special instructions before use; do not handle until all safety precautions have been read and understood.
• P280: wear protective gloves, protective clothing and eye or face protection.
• P210 / P211: keep away from heat, hot surfaces, sparks, open flames and other ignition sources; no smoking; do not spray on an open flame or other ignition source.
• P271: use only outdoors or in a well-ventilated area.
• P260 / P270 / P264: do not breathe dust or mist; do not eat, drink or smoke when using; wash face, hands and any exposed skin thoroughly after handling.
• P251: do not pierce or burn the container, even after use.
• P273: avoid release to the environment.

6. Storage requirements

• P405: store locked up.
• P410 + P412: protect from sunlight; do not expose to temperatures exceeding 50 °C (122 °F).
• P403 + P233: store in a well-ventilated place; keep container tightly closed.

“Store locked up” is one line on the SDS and a concrete task on the line: you need a lockable, ventilated chemical storage location out of sunlight where the ambient temperature does not exceed 50 °C, with controlled issue. In summer, shelves near windows or under the roof of a plant can actually exceed 50 °C, and pressurized containers risk bursting at that temperature.

7. First aid highlights

• Eye contact: rinse immediately with plenty of water, occasionally lifting the upper and lower eyelids; check for and remove contact lenses; continue rinsing for at least 10 minutes and get medical attention.
• Skin contact: rinse the contaminated area with plenty of water; remove contaminated clothing and shoes; before removing clothing, rinse it thoroughly with plenty of water, or wear gloves to handle it; continue rinsing for at least 10 minutes and get medical attention. Wash clothing before reuse and clean shoes thoroughly.
• Inhalation: move to fresh air and keep at rest in a position comfortable for breathing. If vapor may still be present, rescuers should wear a suitable mask or self-contained breathing apparatus. If breathing has stopped or is irregular, trained personnel should give artificial respiration or oxygen. Get medical attention.
• Ingestion: rinse mouth with water and remove dentures. A conscious person may drink a small amount of water; do not induce vomiting unless directed by medical personnel. If vomiting occurs, keep the head low so vomit does not enter the lungs. Never give anything by mouth to an unconscious person.
• Protection of rescuers: do not take action without suitable training or if there is personal risk. Mouth-to-mouth resuscitation of a person poisoned by this product may be dangerous to the rescuer.

8. Exposure symptoms

The manufacturer lists these symptoms of overexposure:

• Inhalation: respiratory tract irritation, coughing, nausea or vomiting, headache, drowsiness / fatigue, dizziness, unconsciousness.
• Skin contact: irritation, redness.
• Listed for all three routes (inhalation, ingestion, skin): reduced fetal weight, increased fetal mortality, skeletal malformations.
• Eye contact: pain or irritation, watering, redness.

The third point deserves special attention: reproductive toxicity symptoms are listed for inhalation, ingestion and skin contact alike, which means skin contact is also an exposure route that must be blocked; a mask alone is not enough. If your plant has workers who are pregnant or planning pregnancy, job assignments involving this product should be evaluated by occupational health staff.

9. Fire and spills

• Extinguishing media: use media appropriate to the surrounding fire. The manufacturer lists no unsuitable media.
• Special hazards: extremely flammable aerosol. Runoff to sewers may create a fire or explosion hazard. Heating raises container pressure and may cause bursting and subsequent explosion. Gas may accumulate in low or enclosed areas, or travel a considerable distance to an ignition source and flash back. Bursting aerosol cans may be propelled at high speed.
• Fire water: this product is harmful to aquatic life with long-term effects; contaminated fire water must be contained and must not be discharged into any waterway, sewer or drain.
• Firefighter protection: wear suitable protective equipment and positive-pressure full-face self-contained breathing apparatus (SCBA).
• Spills: use non-sparking tools and explosion-proof equipment, and approach from upwind. Prevent entry into sewers, waterways, basements or confined spaces. Contain and collect with non-combustible absorbent such as sand, earth, vermiculite or diatomaceous earth. Contaminated absorbent poses the same hazard as the spilled product and must be disposed of according to regulations.

10. Five things to confirm before adoption

• Can ventilation meet “use only outdoors or in a well-ventilated area”: this does not mean switching on a fan. For indoor use, evaluate installing local exhaust ventilation.
• Is protective equipment impermeable: n-hexane is listed as a hazardous substance absorbed through the skin, so cotton gloves are pointless. Choose glove material according to SDS Section 8 and confirm the breakthrough time.
• Can the storage location be locked and kept at or below 50 °C: including actual summer temperatures, not the design temperature.
• Health management measures: the combination of Carcinogenicity 1A, Reproductive toxicity 1A and repeated-exposure organ toxicity Category 1 usually triggers stricter work management and health examination requirements. Have your occupational safety and health staff confirm what is required under current regulations.
• Is there a less hazardous alternative: this is the question to ask first. If the cleaning purpose can be met with a water-based cleaner, a high flash point solvent or a non-flammable solvent, eliminating the hazard at the source is always better than adding protection.

11. What this page is for

This page summarizes the manufacturer’s safety data sheet so you can judge before adoption whether your plant’s conditions are suitable, and so this information can be found by search. It is not a safety data sheet and cannot replace one. Under hazard communication requirements for hazardous chemicals, the line must keep the manufacturer’s full SDS available for workers at any time and provide workers with the necessary hazard communication training. Contact JIAHON to request the full SDS.

FAQ

The composition lists hexane at 60–70%. Does that mean the n-hexane content is high? No. That row is the total for “hexanes (including alkyl isomers),” mainly 2-methylpentane (isohexane). The n-hexane (CAS 110-54-3) content is ≤10%, with a measured value of 2.6% reported under PRTR. The two have different toxicological properties; always distinguish them when citing.

What does Carcinogenicity 1A mean? In the GHS classification, Carcinogenicity Category 1A means “known to have carcinogenic potential for humans,” based mainly on human epidemiological evidence. It is the top carcinogenicity category (1A is above 1B, and 1B above 2). This is not a “possible risk” level.

Are ordinary work gloves enough? No. The SDS explicitly requires impermeable protective equipment, and n-hexane is listed as a hazardous substance absorbed through the skin. Cotton or ordinary fabric gloves not only fail to block it but, once soaked with solvent, keep it against the skin for longer. Choose glove material according to SDS Section 8 and confirm that material’s breakthrough time for this product.

If I only spray it occasionally, does it need to be this strict? H372 (organ damage through prolonged or repeated exposure) is indeed related to cumulative exposure, but H222 (extremely flammable aerosol), H350 and H360 don’t go away because usage is low. The practical advice: whatever the amount, ventilation, impermeable gloves and eye protection cannot be skipped; how often the work is done affects whether local exhaust and health monitoring are needed.

Is there a safer alternative? It depends on the cleaning purpose. Water-based cleaners, high flash point hydrocarbon solvents and non-flammable hydrofluoroether (HFE) solvents each have their range of use for different contaminants and substrates. Send JIAHON the contaminants to be cleaned, the substrate materials and your line conditions, and we can help evaluate whether a less hazardous option exists.

Why not just put the full SDS on the web page? The full SDS is the manufacturer’s document and is updated with new versions. If a web summary doesn’t match the version kept on the line, it creates confusion in management. The right approach is to request the current full SDS from the supplier and keep it on file on the line; this page is for judging whether the product’s hazard level suits your plant before you request it.
