| First Aid Measures | Back to Contents | 【Ingestion】
DO NOT INDUCE VOMITING. If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center. Be prepared to transport the victim to a hospital if advised by a physician. | 【Inhalation】
IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used. | 【Skin】
IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment. | 【Eyes】
First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop. |
| Handling and Storage | Back to Contents | 【Storage】
Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage. | 【Handling】
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood. |
| Hazards Identification | Back to Contents | 【Inhalation】
Symptoms of exposure to this compound may include drowsiness, ataxia, skin rash, dysarthria, nausea, diplopia, anxiety, depression, constipation, changes in salivation, blurred vision, urinary retention, incontinence, tremor, headache, confusion, slurred speech, vertigo, changes in libido and jaundice. Other symptoms of exposure include fatigue, dizziness, respiratory depression, nystagmus, incoordination of the upper extremities, cardiac arrest, hyporeflexia, muscular weakness, agitation, insomnia, grand mal seizures, organic brain syndrome, paradoxical excitement, delirium, coma, hallucinations, vomiting, lethargy and respiratory failure or arrest. | 【Skin】
Bullae have been reported. | 【Eyes】
For pure benzodiazepine ingestions, effects should be minimal, but may include prolonged dialation of the pupils, nystagmus, and divergence paralysis. Constriction of the pupil is also observed. | 【Ingestion】
Nausea and vomiting have been reported. |
| Exposure Controls/Personal Protection | Back to Contents | 【Personal Protection】
Chemical splash goggles in compliance with OSHA regulations are advised; however, OSHA regulations also permit other type safety glasses. Whre chemical resistant gloves. To prevent repeated or prolonged skin contact, wear impervious clothing and boots. | 【Respirators】
Wear a NIOSH-approved half face respirator equipped with an organic vapor/acid gas cartridge (specific for organic vapors, HCl, acid gas and SO2) with a dust/mist filter. | 【Exposure Effects】
Reduced body temperature, respiratory depression, abnormally low blood pressure and low heart rate have been reported in overdose. ataxia, lethargy, sleepiness and slurred speech are common. Coma has been reported. Benzodiazepines may induce or worsen dyskinesia. Patients may be agitated (paradoxical effect) or disorientated, and may experience memory loss, confusion, and difficulty concentrating. Benzodiazepines are excreted in breast milk and may produce effects in the nursing infant. <br>Administration of benzodiazepines prior to delivery may produce signs of poisoning in the neonate. A condition called floppy infant syndrome, characterized by hypotonia that may last several days, may may occur following maternal diazepam use. |

255 | 【Fire Fighting】
Fires involving this material can be controlled with a dry chemical, carbon dioxide or Halon extinguisher. | 【Fire Potential】
This material is probably combustible. |
| Accidental Release Measures | Back to Contents | 【Small spills/leaks】
Should a spill occur while you are handling this chemical, FIRST REMOVE ALL SOURCES OF IGNITION, then you should dampen the solid spill material with 60-70% ethanol and transfer the dampened material to a suitable container. Use absorbent paper dampened with 60-70% ethanol to pick up any remaining material. Seal the absorbent paper, and any of your clothes, which may be contaminated, in a vapor-tight plastic bag for eventual disposal. Solvent wash all contaminated surfaces with 60-70% ethanol followed by washing with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned. |
