| Regulatorische Informationen | n-Propyl nitrate: Does not have an individual approval but may be used as a component in a product covered by a group standard. It is not approved for use as a chemical in its own right.The 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 | Flammable Liquid |
| Brandgefahren | Special Hazards of Combustion Products: Toxic gases and vapors, such as oxides of nitrogen and carbon monoxide, may be released in a fire. (USCG, 1999)· HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames.Highly flammable. Gives off irritating or toxic fumes (or gases) in a fire. Vapour/air mixtures are explosive. Risk of fire and explosion on contact with combustible substances. Explosive. |
| Brandpotenzial | ...It is... flammable, and poses a dangerous fire and explosion risk. |
| Gesundheitsgefahren | Exposure can cause anoxia and cyanosis. Other effects are weakness, dizziness, and severe headaches. (USCG, 1999)CAUTION: Petroleum crude oil (UN1267) may contain TOXIC hydrogen sulphide gas. |
| Gefahrenübersicht | Induces methemoglobinemia in experimental animals at high concentrationsMethemoglobinemia is unlikely in workers because lower concentrations provoke nausea, headache and avoidance of irritating effects[ACGIH] n-Propyl nitrate is in the ACGIH list of Industrial Chemicals for Which Methemoglobin Formation is the Principal Cause of Toxicity A skin, eye, and respiratory tract irritantCan induce methemoglobinemia[ICSC] |
