== Health risks ==
Liquid epoxy resins in their uncured state are mostly classed as [[Irritation|irritant]] to the eyes and skin, as well as toxic to aquatic organisms.<ref name="Holness Nethercott Occupational Contact Dermatitis"/> Solid epoxy resins are generally safer than liquid epoxy resins, and many are classified non-hazardous materials. One particular risk associated with epoxy resins is sensitization. The risk has been shown to be more pronounced in epoxy resins containing low molecular weight epoxy diluents.<ref>Tavakoli, S. M. (2003). [http://www.hse.gov.uk/research/rrpdf/rr079.pdf ''An assessment of skin sensitisation by the use of epoxy resin in the construction industry'']. TWI Ltd. {{ISBN|071762675X }}</ref> Exposure to epoxy resins can, over time, induce an [[Allergy|allergic reaction]]. Sensitization generally occurs due to repeated exposure (e.g. through poor working hygiene or lack of protective equipment) over a long period of time. Allergic reaction sometimes occurs at a time which is delayed several days from the exposure. Allergic reaction is often visible in the form of [[dermatitis]], particularly in areas where the exposure has been highest (commonly hands and forearms). Epoxy use is a main source of [[occupational asthma]] among users of plastics.<ref>[http://www.mayoclinic.com/health/occupational-asthma/DS00591/DSECTION=risk-factors MayoClinic → Occupational asthma] May 23, 2009</ref> Safe disposal also needs considering but usually involves deliberate curing to produce solid rather than liquid waste.<ref>{{Cite web |date=April 2013 |title=Disposal of 2 part epoxy |url=https://www.lion.com/Lion-News/April-2013/How-to-Dispose-of-2-Part-Epoxy-Solutions}}</ref>
