4. Safety Information

A. General Handling

• Wear gloves to prevent contamination and avoid skin contact.
• Store in a clean, dry environment to minimize exposure to moisture and contaminants.

B. Health and Safety Hazards

• Inhalation: Dust generated during cutting or drilling may cause respiratory irritation.
  • Use proper ventilation or dust extraction systems.
  • Wear a dust mask or respirator (NIOSH-approved).
• Skin Contact: Prolonged exposure to dust may cause mild skin irritation.
  • Wash with soap and water after handling.
• Eye Contact: Dust particles can cause mechanical irritation.
  • Use protective eyewear when machining or drilling.

C. Thermal Decomposition

• Avoid prolonged exposure to temperatures above the recommended operating range.
• Thermal decomposition may produce harmful gases, including hydrocarbons and trace amounts of formaldehyde.

5. Fire Safety

• Flammability: RO4000 laminates are considered self-extinguishing.
• Firefighting Measures:
  • Use water spray, foam, or dry chemical extinguishers.
  • Wear appropriate protective equipment to avoid inhalation of fumes.

6. Disposal and Recycling

• Disposal: Dispose of scrap materials and waste in accordance with local, regional, and national regulations.
• Recycling: Contact authorized recycling facilities to handle electronic waste containing RO4000 laminates.

7. Storage and Shelf Life

• Storage Conditions:
  • Temperature: 23°C (73°F).
  • Relative Humidity: 50%.
  • Store flat to prevent warping or mechanical damage.
• Shelf Life:
  • Typically unlimited when stored under recommended conditions.

8. Regulatory Compliance

• RoHS Compliance: RO4000 series laminates comply with the Restriction of Hazardous Substances (RoHS) directive.
• REACH Compliance: These laminates meet the requirements of the Registration, Evaluation, Authorization, and Restriction of Chemicals (REACH) regulation.
