Rinse mouth with water. Do not induce vomiting. Never give anything by mouth to an unconscious person. Call a doctor or Poison Control Center immediately.
Most important symptoms/effects, acute and delayed
SYMPTOMS: Symptoms of exposure to this compound include sedation, nausea, drowsiness, ataxia and coma (from large doses). Other symptoms include vomiting, lethargy, hyporeflexia, muscular weakness, dysarthria, nystagmus, hypotension, respiratory failure and death from respiratory or cardiac arrest. Exposure can cause syncope, liver damage, bone marrow damage and sensitivity reactions. It can also cause dryness of the mouth, aggressive behavior, blood dyscrasias and hepatic dysfunction. Sleepiness has been reported. It may cause lightheadedness, respiratory depression, constipation, changes in salivation, blurred vision, diplopia, urinary retention, incontinence, mental depression, tremor, headache, confusion, slurred speech, vertigo, changes in libido, blood disorders, jaundice, central nervous system depression and, sometimes, paradoxical reactions such as dysphoria. It may also cause skin rashes (morbilliform, urticarial and maculopapular), dizziness, stimulation of affect, leukopenia, severe rage reactions (rare), menstrual irregularities, change in EEG pattern, agranulocytosis, stupor, disorientation, fever, euphoria, transient amnesia and memory impairment. Exposure to children has resulted in somnolence, changes in REM sleep and loss of muscle control (ataxia). It has also caused lethargy, paradoxical excitation, depressed reflexes, facial edema, delirium, hallucinations and convulsions. ACUTE/CHRONIC HAZARDS: When heated to decomposition this compound emits very toxic fumes of nitrogen oxides and hydrogen chloride. (NTP, 1992)
Indication of immediate medical attention and special treatment needed, if necessary
Treatment is entirely supportive with IV access and fluids and maintenance of the airway and ventilation if required. Patients with a significant sedative drug overdose should be advised not to drive until potential interference with psychomotor performance has resolved. For significant benzodiazepine overdose, this is at least 24 hours after discharge./Benzodiazepines/
SECTION 5: Firefighting measures

Fires involving this material can be controlled with a dry chemical, carbon dioxide or Halon extinguisher. (NTP, 1992)
Specific hazards arising from the chemical
Flash point data for this chemical are not available; however, it is probably combustible. (NTP, 1992)
Special protective actions for fire-fighters
Wear self-contained breathing apparatus for firefighting if necessary.
SECTION 6: Accidental release measures
Personal precautions, protective equipment and emergency procedures
Avoid dust formation. Avoid breathing mist, gas or vapours.Avoid contacting with skin and eye. Use personal protective equipment.Wear chemical impermeable gloves. Ensure adequate ventilation.Remove all sources of ignition. Evacuate personnel to safe areas.Keep people away from and upwind of spill/leak.
Environmental precautions
Prevent further spillage or leakage if it is safe to do so. Do not let the chemical enter drains. Discharge into the environment must be avoided.
Methods and materials for containment and cleaning up
Collect and arrange disposal. Keep the chemical in suitable and closed containers for disposal. Remove all sources of ignition. Use spark-proof tools and explosion-proof equipment. Adhered or collected material should be promptly disposed of, in accordance with appropriate laws and regulations.
SECTION 7: Handling and storage
Precautions for safe handling
Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
Conditions for safe storage, including any incompatibilities
Oxazepam capsules and tablets should be stored in well-closed containers at a temperature less than 40 deg C, preferably at 15-30 deg C.
SECTION 8: Exposure controls/personal protection
Control parameters
no data available
no data available
Appropriate engineering controls
Ensure adequate ventilation. Handle in accordance with good industrial hygiene and safety practice. Set up emergency exits and the risk-elimination area.
Individual protection measures, such as personal protective equipment (PPE)
Wear tightly fitting safety goggles with side-shields conforming to EN 166(EU) or NIOSH (US).
Wear fire/flame resistant and impervious clothing. Handle with gloves. Gloves must be inspected prior to use. Wash and dry hands. The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it.
If the exposure limits are exceeded, irritation or other symptoms are experienced, use a full-face respirator.

Carcinogenicity
Evaluation: There is inadequate evidence in humans for the carcinogenicity of oxazepam. There is sufficient evidence in experimental animals for the carcinogenicity of oxazepam. Overall Evaluation: Oxazepam is possibly carcinogenic to humans (Group 2B). In making the overall evaluation, the Working Group took into account that: (1) uncertainty exists regarding the formation of mouse liver tumors by oxazepam as a relevant end point for evaluation of carcinogenic risks to humans. (2) appropriate mechanistic information in humans is lacking.

Bioaccumulative potential
An estimated BCF of 11 was calculated for oxazepam(SRC), using a log Kow of 2.24(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
Mobility in soil
The Koc of oxazepam is estimated as 390(SRC), using a log Kow of 2.24(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that oxazepam is expected to have moderate mobility in soil.
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
