| Regulatorische Informationen | Chemical: Oxirane, 2,2'-[oxybis(methylene)]bis-TP - indicates a substance that is the subject of a proposed TSCA section 4 test rule.Diglycidyl ether: Does not have an individual approval but may be used under an appropriate group standardThe New Jersey Worker and Community Right to Know Act requires public and private employers to provide information about hazardous substances at their workplaces. (N.J.S.A. 34:5A-1 et. seq.) |
| DOT-Kennzeichnung | Corrosive Poison |
| Brandgefahren | Excerpt from ERG Guide 154 [Substances - Toxic and/or Corrosive (Non-Combustible)]:Combustible. Above 64 °C explosive vapour/air mixtures may be formed. |
| Gesundheitsgefahren | This compound can cause death or permanent injury via oral and inhalation routes during exposure that comes from normal use. It is incapacitating and poisonous and requires special handling. It can cause considerable discomfort by the dermal route. (EPA, 1998) |
| Gefahrenübersicht | The TLV is based on male reproductive effects and irritation to the skin and eyes. Male rats develop reproductive toxicity after 60 4-hour exposures to 0.3 ppm. High concentrations induce CNS depression in experimental animals. In the past, some workers developed slow healing burns. [ACGIH] Severely irritating to the respiratory tract and may cause pulmonary edemaMay cause skin sensitization[ICSC] |
| Reaktive Gruppe | Ethers |
| TSCA-Anforderungen | Pursuant to section 8(d) of TSCA, EPA promulgated a model Health and Safety Data Reporting Rule. The section 8(d) model rule requires manufacturers, importers, and processors of listed chemical substances and mixtures to submit to EPA copies and lists of unpublished health and safety studies. Oxirane, 2,2'-(oxybis(methylene))bis- is included on this list. |
Anwendungen & Verwendung
Verwenden
Diglycidyl ether is significant only because it is a possible trace component of epoxy compounds derived from epichlorohydrin.
