Is epichlorohydrin hazardous?
Safety. Epichlorohydrin is classified by several international health research agencies and groups as a probable or likely carcinogen in humans. Prolonged oral consumption of high levels of epichlorohydrin could result in stomach problems and an increased risk of cancer.
Is epichlorohydrin flammable?
Epichlorohydrin is a FLAMMABLE and REACTIVE LIQUID that can polymerize violently when exposed to HEAT. Use dry chemical, CO2, water spray or alcohol-resistant foam as extinguishing agents. Epichlorohydrin may form an ignitable vapor/air mixture in closed tanks or containers.
What PPE is needed when using epichlorohydrin?
| Personal Protective Equipment Use | During Chemical Preparation |

| Safety glasses (impact) | ☐ |
| Safety goggles (splash) | ☒ |
| Lab Coat | ☒ |
Is epichlorohydrin volatile?
Epichlorohydrin is an epoxide compound that is volatile, highly reactive and unstable. Most commonly, epichlorohydrin is combined with Bisphenol A to form Epoxy resins. Epichlorohydrin has also been used as an Insecticide.
What is epichlorohydrin made from?
Epichlorohydrin (1-chloro-2,3-epoxy propane), is obtained by the chlorination of propylene, followed by the reaction of allyl chloride with hypochlorous acid.
What is the pH of epichlorohydrin?
Epichlorohydrin, which is colourless and poorly soluble in water and has a pungent, chloroform-like odour, is converted to 3-chloro-1,2-propanediol (α-chlorohydrin) in an aqueous milieu at a pH of 7 and 20°C.
What is epichlorohydrin used for?
Epichlorohydrin (ECH) is an intermediate chemical used in the production of epoxy resins (about 90% of the total global market), synthetic glycerin, epichlorohydrin elastomers, specialty water treatment chemicals, wetstrength resins for paper production, and surfactants.
How is epichlorohydrin made?
At commercial scale, epichlorohydrin is mainly produced via chlorohydrination of allyl chloride, obtained in turn from the chlorination of propylene at high-temperature. Epichlorohydrin is mainly used in the production of bisphenol A, a raw material for epoxy resins, glycerol, and elastomers.
How is epichlorohydrin manufactured?
Where is epichlorohydrin used?

How is epichlorohydrin used in the workplace?
Epichlorohydrin is mainly used in the production of epoxy resins. Acute (short-term) inhalation exposure to epichlorohydrin in the workplace has caused irritation to the eyes, respiratory tract, and skin of workers.
What are the risks of exposure to epichlorohydrin?
Exposures to epichlorohydrin ranged from below 1 ppm (8-hour TWA) to between 1 and 5 ppm (8-hour TWA), depending on the year of exposure and production area. The study results did not support an increased risk for malignant neoplasms, including respiratory system cancer, with past exposure to epichlorohydrin.
What is the current OSHA PEL for epichlorohydrin?
CAS number: 106–89–8. NIOSH REL: None established; NIOSH considers epichlorohydrin to be a potential occupational carcinogen as defined by the OSHA carcinogen policy [29 CFR 1990]. Current OSHA PEL: 5 ppm (19 mg/m 3) TWA [skin]
What is the NIOSH REL for epichlorohydrin?
NIOSH REL: None established; NIOSH considers epichlorohydrin to be a potential occupational carcinogen as defined by the OSHA carcinogen policy [29 CFR 1990]. Description of Substance: Colorless liquid with a slightly irritating, chloroform-like odor.
