When handling transformer oil, it is important to wear appropriate personal protective equipment (PPE) to prevent contact with skin and eyes, and to avoid inhalation of vapors and mists [1]. The specific PPE required may vary depending on the specific product and the levels of exposure, so a risk assessment should be performed to determine the appropriate level of protection 7, 15, 18, 20.

Based on the provided documents, the following PPE is generally recommended when handling transformer oil:

• Eye protection: Use close-fitting safety goggles or a face shield 1, 5, 10, 18, 20. Avoid using eye lenses [1].
• Skin protection: Wear clothing that provides comprehensive protection to the skin, such as cotton, rubber, PVC, or viton 1, 13. Use chemical-resistant, impervious gloves 7, 15, 18. Suitable materials for safety gloves include Polychloroprene - CR (thickness >=0,5mm; breakthrough time >=480min), Nitrile rubber NBR (thickness >=0,35mm; breakthrough time >=480min), Butyl rubber - IIR (thickness >=0,5mm; breakthrough time >=480min), and Fluorinated rubber FKM (thickness >=0,4mm; breakthrough time >=480min) 1, 17.
• Respiratory protection: If exposure limits are exceeded or if there is inadequate ventilation, use a NIOSH/MSHA or European Standard EN 149 approved respirator 3, 5, 17, 18, 20. Follow the OSHA respirator regulations found in 29 CFR 1910.134 or European Standard EN 149 3, 5.

In addition to the above, it is important to follow good hygiene practices, such as washing hands and face thoroughly before eating, smoking, and using the lavatory, and at the end of the working period 7, 18, 19. Contaminated clothing should be removed and washed before reusing 1, 7, 18.
