1,1-Dichloro-1,2,3,3,3-pentafluoropropane (HCFC-225eb)

Industrial production of HCFCs; used as a cleaning agent in electronics, aerospace, and metal parts; releases mainly to air during use [1][2].

Breathing vapors at work during degreasing or cleaning; smaller exposures from leaks or contaminated indoor air near use/storage [2][3].

Short‑term exposure can cause dizziness, headache, and irritation of eyes and skin; very high levels can depress the central nervous system [2][3]. It also harms the ozone layer and contributes to climate change [1].

Workers in precision cleaning, maintenance technicians, and people in poorly ventilated shops; pregnant workers and those with respiratory conditions should take extra care [1][2].

Use safer substitutes when possible; keep processes enclosed and ventilated; wear appropriate gloves and eye protection; store and handle in sealed systems; review the Safety Data Sheet; avoid home use [1][2][3].
