FAQ – 3M™ Adhesivo Sellador para Marina 4200 FC
-
Is this product classified as hazardous?
Yes. It is classified as a respiratory sensitiser (Category 1, H334) and a skin sensitiser (Category 1, H317).
-
What health effects can occur from exposure?
Inhalation can cause respiratory irritation and allergic reactions (difficulty breathing, wheezing, chest tightness). Skin contact can provoke allergic skin reactions (redness, swelling, blisters, itching). Ingestion may irritate the gastrointestinal tract.
-
What should I do in case of inhalation of vapours?
Move the person to fresh air and keep them in a position that facilitates breathing. If respiratory symptoms occur, call a poison centre or doctor.
-
How should the product be stored?
Keep the container tightly closed to avoid contamination with water or air. Store away from strong acids, strong bases, oxidising agents and amines. If contamination is suspected, do not reseal the container.
-
Is special training required to use this product?
Yes. From 24 August 2023, appropriate training is mandatory for industrial or professional use due to the presence of diisocyanates.
-
Is it dangerous for the environment?
The mixture contains components that are harmful or very toxic to aquatic organisms with long-lasting effects, but the product itself has no complete test data; it should not be released into the environment.
-
How should spills be handled?
Evacuate and ventilate the area, prevent release to the environment, collect as much material as possible, place it in a suitable container and do not seal it for 48 hours to avoid overpressure. Dispose of collected material according to applicable regulations.
-
How should waste and empty containers be disposed of?
Dispose of contents and container in accordance with local, regional, national and international legislation. Uncured product can be incinerated in an authorised facility. Empty containers that have held hazardous mixtures must be handled and disposed of as hazardous waste.
-
Is it classified as dangerous for transport?
No. The safety data sheet specifies that the product is not dangerous for transport.

Section 8 – Individual protection measures
Engineering controls
- Use general dilution and/or local exhaust ventilation to keep airborne contaminants below occupational exposure limits.
- If ventilation is inadequate, respiratory protection must be used.
Eye and face protection
- Select eye and face protection to prevent contact based on exposure assessment.
- Recommended: Safety glasses with side shields.
- Use eye protection conforming to EN 16321.
Hand and skin protection
- Use gloves and/or protective clothing approved under relevant local standards to avoid skin contact.
- Selection should consider exposure level, concentration, contact frequency and duration, and physical conditions such as temperature.
- Recommended glove materials include:
- Polyvinyl alcohol (PVA)
- Laminated polymer
- Gloves should be tested according to EN 374.
- Nitrile gloves may be used over laminated polymer gloves to improve dexterity.
- For higher exposure potential (for example spraying or high splash risk), a protective apron made from materials equivalent to the recommended glove materials may be required.
Respiratory protection
- An exposure assessment may be necessary to determine the need for respiratory protection.
- When required, use respiratory protection as part of a comprehensive respiratory protection programme.
- Depending on exposure, use a half-mask or full-facepiece air-purifying respirator suitable for organic vapours and particulates.
- Respiratory protective devices should comply with EN 140 or EN 136 and use A and P type filters.
