Section 8 – Personal protective measures

Engineering controls

• Provide adequate general and local exhaust ventilation to keep aerosol and solvent vapour concentrations below occupational exposure limits.
• If ventilation is insufficient, suitable respiratory protection must be worn.

Personal protective equipment (PPE)

• Eye/face protection: Safety goggles to protect against solvent splashes.
• Hand protection:
  • Use chemical-resistant protective gloves tested in accordance with EN 374.
  • Recommended for splash contact: nitrile rubber or neoprene.
  • Minimum material thickness: > 0.4 mm.
  • Breakthrough time: > 480 minutes.
  • Check gloves for workplace suitability and replace immediately if damaged or worn.
• Skin and body protection: Wear suitable protective clothing adapted to the risk of explosive atmospheres where applicable.
• Respiratory protection: If solvent concentrations exceed air limit values, wear an approved respirator (half mask with cartridge or air-fed system). In spray booths, operators may need compressed air-fed respirators until solvent vapour and particulate levels fall below exposure limits.

General protective measures

• Do not eat, drink or smoke while using this product.
• Avoid contact with skin, eyes and clothing.
• Avoid inhalation of sanding dust, spray mist and solvent vapours.
• Use appropriate anti-static footwear and clothing; avoid sparks and open flames.
