HVAC technicians should use personal protective equipment (PPE) to minimize exposure to hazards. Based on the provided documents, appropriate PPE includes:

• Eye Protection: Safety glasses with side shields or safety goggles are recommended to protect against splashes or spraying of product 2, 6, 18. Full face protection should be used if the potential for splashing or spraying of product exists [1].
• Hand Protection: Chemical-resistant, impervious gloves should be worn when handling chemical products 11, 12, 18, 19. Gloves made from nitrile rubber are suitable for short-term work or as a splash guard [2]. It is important to check the gloves during use to ensure they are still retaining their protective properties 11, 12, 18.
• Skin and Body Protection: Suitable protective clothing should be worn to provide comprehensive protection to the skin 1, 4, 7, 14, 15. When there is a risk of ignition from static electricity, wear anti-static protective clothing [3].
• Respiratory Protection: Use a NIOSH-approved air-purifying respirator if there is a potential to exceed exposure limits 2, 6, 16, 19. If workers are exposed to concentrations above the exposure limit, they must use appropriate, certified respirators [3].

Employers should assess all workplaces to determine the need for, and selection of, proper exposure controls and protective equipment for each task performed 2, 6, 16, 19.
