Ethylamine

Ethylamine is a colorless liquid or gas with a strong ammonia-like odor[1][3]. It has a boiling point of 62°F and a flash point less than 0°F, making it highly flammable[1][3]. The density of the liquid is 5.7 lb/gal[1]. Ethylamine is corrosive to the skin and eyes, and its vapors are heavier than air, which can travel a considerable distance to a source of ignition and flash back, potentially causing containers to explode when heated[1][3]. Inhalation of ethylamine can cause irritation of the respiratory tract and lungs, and liquid contact can lead to severe irritation and burns of the eyes and skin[1][3]. Prolonged exposure can result in permanent eye damage and affect the eyes, causing blurred vision and seeing halos around lights[3].

The chemical is used in various applications, including the production of agricultural chemicals, mining chemicals, and polyurethane[4]. It is also regulated by OSHA and cited by ACGIH, DOT, NIOSH, NFPA, and EPA due to its hazardous properties[3].

OSHA has set a Process Safety Management (PSM) Standard List threshold quantity of 7500 pounds for ethylamine[1]. The NIOSH Pocket Guide to Chemical Hazards recommends a REL TWA of 10 ppm (18 mg/m3) and an IDLH of 600 ppm[5]. The CDC advises that exposure to ethylamine can affect the eyes, skin, and respiratory system, and recommends specific personal protective equipment and first aid measures[5].
