| Hazards and Protection. | |
| Storage | Keep away from heat, sparks, and flame. Keep away from sources of ignition. Keep container closed when not in use. Store in a cool, dry, well-ventilated area away from incompatible substances. Flammables-area. |
| WHMIS | B2 D1B E |
| Handling | Wash thoroughly after handling. Ground and bond containers when transferring material. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Keep container tightly closed. Avoid contact with heat, sparks and flame. Do not get on skin or in eyes. Do not ingest or inhale. Use only in a chemical fume hood. Wash clothing before reuse. Discard contaminated shoes. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames. |
| Protection | Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure. |
| Respirators | A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever workplace conditions warrant a respirator's use. |
| Small spills/leaks | Absorb spill with inert material, (e.g., dry sand or earth), then place into a chemical waste container. Avoid runoff into storm sewers and ditches which lead to waterways. Clean up spills immediately, using the appropriate protective equipment. Remove all sources of ignition. Use a spark-proof tool. Provide ventilation. A vapor suppressing foam may be used to reduce vapors. |

| Fire fighting | Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent) and full protective gear. Use water spray to keep fire-exposed containers cool. Extremely flammable liquid. Water may be ineffective. Material is lighter than water and a fire may be spread by the use of water. Containers may explode in the heat of a fire. Extinguishing media: For small fires, use dry chemical, carbon dioxide, water spray or alcohol-resistant foam. For large fires, use water spray, fog, or alcohol resistant foam. | |||
| Fire potential | Very flammable. Flammable liquid. | |||
| Hazards | Vapor is heavier than air and may travel to a source of ignition and flash back. Water runoff can cause environmental damage. Dike and collect water used to fight fire. Vapors may form an explosive mixture with air. Vapors can travel to a source of ignition and flash back. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. | |||
| Combustion products | Toxic oxides of nitrogen may be formed in a fire. | |||

| Exposure limit(s) | TLV (as for n-Butylamine): 5 ppm; 15 mg/m3 as CEILING (skin) (ACGIH 1991-1992). MAK as : 5 ppm; 15 mg/m3 I,H (1990). |
| Poison_Class | 2 |
| Exposure effects | Headaches may ensue after inhalation of the vapor. CNS effects were seen in animals exposed to the vapor. No data were available to assess the teratogenic potential of this agent. <br>No data were available to assess the potential effects of exposure to this agent during pregnancy or lactation. |
| Ingestion | Harmful if swallowed. May cause severe and permanent damage to the digestive tract. Causes gastrointestinal tract burns. |
| Inhalation | Causes chemical burns to the respiratory tract. Causes irritation of mucous membrane. Vapors may cause dizziness or suffocation. |
| Skin | Causes severe burns. |
| Eyes | Causes severe eye burns. |
First aid |
|
| Ingestion | Do NOT induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid immediately. |
| Inhalation | Get medical aid immediately. Remove from exposure to fresh air immediately. If breathing is difficult, give oxygen. DO NOT use mouth-to-mouth respiration. If breathing has ceased apply artificial respiration using oxygen and a suitable mechanical device such as a bag and a mask. |
| Skin | Get medical aid immediately. Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse. Destroy contaminated shoes. |
| Eyes | Get medical aid immediately. Do NOT allow victim to rub or keep eyes closed. Extensive irrigation is required (at least 30 minutes). |
