3. Hazards Identification

Emergency Overview
--------------------------
WARNING! HARMFUL IF SWALLOWED OR INHALED. CAUSES RESPIRATORY TRACT IRRITATION. CHRONIC EXPOSURE MAY AFFECT LIVER.

Potential Health Effects
----------------------------------

Inhalation:
Inhalation of dust can irritate the respiratory tract. Other symptoms may parallel those from ingestion.
Ingestion:
At therapeutic doses, may cause drowsiness, dizziness, cognitive impairment, anxiety, mood alteration, gastrointestinal pain, and nausea. At higher than therapeutic doses, may cause liver toxicity.
Skin Contact:
Not expected to cause any adverse health effects.
Eye Contact:
No adverse effects expected but dust may cause mechanical irritation.
Chronic Exposure:
Repeated ingestion may cause liver damage.
Aggravation of Pre-existing Conditions:
Produces acute withdrawal symptoms in individuals physically dependent on opiods. Persons with impaired kidney or liver function may be more susceptible to the effects of the substance.

4. First Aid Measures

Inhalation:
Remove to fresh air. Get medical attention for any breathing difficulty.
Ingestion:
If large amounts were swallowed, give water to drink and get medical advice.
Skin Contact:
Wash exposed area with soap and water. Get medical advice if irritation develops.
Eye Contact:
Immediately flush eyes with plenty of water for at least 15 minutes, lifting lower and upper eyelids occasionally. Get medical attention immediately.

5. Fire Fighting Measures

Fire:
As with most organic solids, fire is possible at elevated temperatures or by contact with an ignition source.
Explosion:
No information found.
Fire Extinguishing Media:
Water spray, dry chemical, alcohol foam, or carbon dioxide.
Special Information:
In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full facepiece operated in the pressure demand or other positive pressure mode. Follow handling guidance appropriate for OEB-2 potent compounds, (see Section 7).

6. Accidental Release Measures

Ventilate area of leak or spill. Wear appropriate personal protective equipment as specified in Section 8, and follow handling guidance appropriate for OEB-2 potent compounds, (see Section 7). Isolate hazard area. Keep unnecessary and unprotected personnel from entering.
Spills: Carefully sweep up material into an appropriate container and save for reclamation or disposal. Do not flush to sewer!

7. Handling and Storage

Store at controlled room temperature 15-30C (59-86F). Containers of this material may be hazardous when empty since they retain product residues (dust, solids); observe all warnings and precautions listed for the product.
Naltrexone Hydrochloride has potent pharmacological activity and is classified as an OEB-2* material. Handling practices for OEB-2 substances are described below:

Laboratory
*Wear appropriate gloves, lab coat, and safety glasses. Use good lab practices.
*No local exhaust ventilation required for transfer/handling of quantities of powder less than 100 g (total weight transferred or handled). However, if the source container contains 2 kg or more, pilot plant practices apply.
*No local exhaust ventilation required for solutions of these compounds.
*Quantities of solid above 100 g require use of a powders weighing hood or other approved containment/ventilation system.
*High-energy operations such as milling, particle-sizing, spraying or fluidizing should be done within an approved emission control or containment system.
*Develop cleaning procedures and techniques that limit potential exposure.

Pilot Plant and Production
*Wear appropriate gloves; lab coat, nylon coveralls or disposable Tyvek suit; safety glasses and safety shoes. Use good manufacturing practices (i.e., cGMPs).
*Use local exhaust and/or enclosure at dust-generating points. Emphasis is to be placed on closed material transfer systems and process containment, with limited open handling of powders.
*Where open handling of powders occurs, use a powered, air-purifying respirator (PAPR) with HEPA cartridges or a supplied-air respirator (SAR), unless air-monitoring data has shown that a lower level of respiratory protection is adequate.
*Protective garments (coveralls, Tyveks, lab coat) are not to be worn in common areas (e.g., cafeterias) or out-of-doors.
*High-energy operations such as milling, particle-sizing, spraying or fluidizing should be done within an approved emission control or containment system.
*Develop cleaning procedures and techniques that limit potential exposure.

*OEB - Mallinckrodt's Occupational Exposure Band: The classification of a compound or pharmaceutical ingredient into one of four ordinal categories of increasing potency and toxicity. This rating assigns a set of pre-determined handling and containment practices to a compound until a quantitative OEL is established.

8. Exposure Controls/Personal Protection

Airborne Exposure Limits:
Naltrexone hydrochloride:
Occupational Exposure Guidelines (OEG): 50ug/m3, as 8-hour time-weighted average
Short-term Exposure Guidelines (STEG): 500ug/m3, as 15-minute average.
Ventilation System:
A system of local and/or general exhaust is recommended to keep employee exposures below the Airborne Exposure Limits. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area. Please refer to the ACGIH document, Industrial Ventilation, A Manual of Recommended Practices, most recent edition, for details.
Personal Respirators (NIOSH Approved):
Where open handling of powders occurs, use a powered, air-purifying respirator (PAPR) with HEPA cartridges or a supplied-air respirator (SAR), unless air-monitoring data has shown that a lower level of respiratory protection is adequate.
Skin Protection:
Wear protective gloves and clean body-covering clothing.
Eye Protection:
Use chemical safety goggles. Maintain eye wash fountain and quick-drench facilities in work area.
Other Control Measures:
See Section 7 for additional information on occupational control measures appropriate for OEB-2 potent compounds.
