Hazards and Protection.
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.
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.
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.
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.
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.
Effloresces slowly in dry air, affected by light. Store codeine phosphate injection between 15 and 30 C and protected from light. Freezing should be avoided. Do not use the injection if it is discolored or contains a precipitate.
Incompatible with bromides, iodides and salts of heavy metals Incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides Flammable gaseous hydrogen is generated in combination with strong reducing agents, such as hydrides.
When heated to decomposition it emits toxic fumes of oxides of nitrogen.

Fire fighting
Fires involving this material can be controlled with a dry chemical, carbon dioxide or Halon extinguisher.
Fire potential
This chemical is combustible.

Exposure effects
Abnormally low blood pressure and elevated body temperature or reduced body temperature may occur. lethargy and coma associated with pinpoint pupils occur frequently. Coma, seizures, myoclonic reactions, and spongiform encephalopathy and myelopathy have been reported in abusers of opioids.
Respiratory depression leading to respiratory arrest, pulmonary edema, hypoxia, bronchospasm, acute asthma, bullous pulmonary damage, and pneumonitis have occurred and abuse of opioids.
Rash has been reported during therapeutic use of opioid narcotics. Seborrhea may be seen following mptp overdoses. Scleroderma following heroin abuse has been reported and may be linked to talc mixed with heroin.
Pupils are usually pinpoint but may be dilated in the presence of severe acidosis, hypoxia, or respiratory depression.

First aid
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. If the victim is convulsing or unconscious, do not give anything by mouth, ensure that the victim's airway is open and lay the victim on his/her side with the head lower than the body. DO NOT INDUCE VOMITING. IMMEDIATELY transport the victim to a hospital.
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.
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.
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.
