  • Sequencing reagent bottles contain chemical waste that should be discarded as chemical waste in the chemical hood  and labeled in accordance to the safety guidelines.
  • The Shimadzu Protein sequencer uses the following reagents:
  • Trimethlamine- Flammable liquid, Category 1, H224 Acute toxicity, Category 4, Oral, H302 Skin corrosion, Category 1B, H314 Specific target organ toxicity - single exposure, Category 3, Respiratory system, H335
  • Ethyl Acetate- Highly flammable liquid and vapor Causes serious eye irritation May cause drowsiness and dizziness Prolonged or repeated contact may dry skin and cause irritation or cracking
  • Trifluoroacetic Acid- May be corrosive to metals Causes severe skin burns and eye damage May cause respiratory irritation
  • 1-chlorobutane- Highly flammable liquid and vapor May be fatal if swallowed and enters airways
  • Phenyl Isothyocynate (5%)- Combustible liquid Causes severe skin burns and eye damage May cause respiratory irritation May cause an allergic skin reaction May cause allergy or asthma symptoms or breathing difficulties if inhaled Suspected of damaging the unborn child Toxic if swallowed, in contact with skin or if inhaled
  • Acetonitrile- Potential Acute Health Effects: Hazardous in case of skin contact (irritant), of eye contact (irritant), of ingestion, of inhalation. Slightly hazardous in case of skin contact (permeator). DEVELOPMENTAL TOXICITY: Classified Reproductive system/toxin/female, Reproductive system/toxin/male [SUSPECTED].
  • All above reagents must NEVER be discharged to the sanitary sewer in ANY concentration. These wastes must be collected and managed as chemical waste.
  • When clearing the chemical waste, ensure the chemical hood is properly turned on, use protective wear and keep all containers in the hood tightly closed when not in use.
  • Wash hands thoroughly each time gloves are removed.
  • Remove waste containers to proper location when full.
