Irritative, low-MW degradation products may be produced in the tooling of epoxy products and in heating processes (Engstrom and Henriks-Eckerman 1988). Amine and anhydride hardeners and epi-chlorohydrin irritate the skin and conjunctivae. In addition to causing irritant contact dermatitis, epi-chlorohydrin, as a highly reactive compound, and aliphatic polyamines, as highly alkaline compounds (pH 13-14), can cause corrosive burns on the skin (Ippen and Mathies 1970 Adams 1983). Ippen and Mathies (1970) described protracted chemical burns minutes or several hours after the exposure of five patients to epichlorohydrin. [Pg.584]

A finished composite product only occasionally causes an allergy. Allergic contact dermatitis (ACD) has been reported from limb prostheses made from UP resin (Mac Farlane et al. 1986 Freeman 1986 Vincenzi et al. 1991). ACD has also been caused by unpolymerized epoxy resin in a billiard cue (Gon alo et al. 1992), a screwdriver handle (Fischer et al. 1987) and a mop handle (Jolanki et al. 1992). Glass fibres in a school desk and in printed circuit boards have caused irritant contact dermatitis (ICD) (Koh et al. 1992 Eby and Jetton 1972). [Pg.613]

It is sometimes recommended that persons subject to allergy should not be allowed to come in contact with epoxy resin systems. This would be an improbably measure to observe, it must be kept in mind that exposure to epoxy resin systems cannot cause anything but skin dermatitis. There has been absolutely no evidence of any carcinogenic effect from contact with these systems. Where slight irritations occur, desensitization should first be attempted. If eczema occurs, standard medical treatment should be provided. Antihistamine drugs may be used only to reduce itching. In severe cases, such as in the second stage of dermatosis, cortisone ointments have been used successfully to relieve the symptoms. It should be kept in mind that if protective measures are scrupulously observed, incidents of dermatoses from epoxy resin systems can be kept to a very low minimum. There is no reason for any concern in the use of these systems in the construction industry. [Pg.60]

Construction workers risk occupational contact dermatitis from exposure to irritants, chromate, cobalt, rubber and epoxy. Nickel allergy, however, is not often discussed in relation to construction work (Coenraads et al. 1984). In construction workers it is often found together with allergy to chromate and/or cobalt, and nickel in cement has been proposed as a cause. However, nickel in cement exists mainly as insoluble salts (Wahlberg et al. 1977 Goh et al. 1986). [Pg.528]

Nearly all available plastics are applied in order to prevent further corrosion of stones. Application methods include coating, low pressure or vacuum. Irritant or allergic dermatitis is possible. Epoxy resins and acrylates are the most common plastics causing allergic dermatitis, including airborne dermatitis [1, 2]. Polyester plastics are also used, but rarely produce sensitisation however, additives may cause allergy... [Pg.1100]

Methylhexahydrophthalic anhydride (MHHPA) is an epoxy hardener, irritant to skin and mucus membranes. It is included in non-diglycidyl-ether-of-bis-phenol-A epoxy resins. It can induce both allergic contact dermatitis and immunologic contact urticaria. MHHPA is structurally close to methyltetrahydro-phthalic anhydride (MTHPA), which can also cause sensitization. [Pg.1161]

Sensitisers, on the other hand, do not cause dermatitis until the individual has first become sensitised by them. This involves an allergic response in the blood initially, the dermatitis following on subsequent exposure. Once sensitisation has occurred a small dose may be sufficient to cause a rash. Sensitisers include chrome-salts, nickel, cobalt, plastics made of epoxy, fomaldehyde, urea or phenolic resins, rubber additives, some woods and plants Some substances act as both irritant and sensitiser, e.g. chrome, nickel, turpentine and mercury compounds. [Pg.346]

As noted, epoxy resins are known to be skin sensitizers while the hardeners are classified as corrosives and irritants by inhalation or when in contact with the skin. The primary skin irritation (i.e. eontaet dermatitis) is due to the direct action of the material on the skin and is loealized only in the contact area its degree is directly related both to the eoneentration of the chemical and to the duration of the exposure. In contrast, skin sensitization (i.e. allergic dermatitis) is different from contact dermatitis, even if they often appear... [Pg.114]
