Isophoronediamine: Does not have an individual approval but may be used under an appropriate group standard

The New Jersey Worker and Community Right to Know Act requires public and private employers to provide information about hazardous substances at their workplaces. (N.J.S.A. 34:5A-1 et. seq.)

Excerpt from ERG Guide 153 [Substances - Toxic and/or Corrosive (Combustible)]:

· Combustible material: may burn but does not ignite readily.

Combustible.

Inhalation of high concentrations of vapor causes irritation, coughing, and nausea. Eyes: May cause inflammation/burns. Skin: May cause burns. Ingestion: Nausea. (USCG, 1999)

· TOXIC and/or CORROSIVE; inhalation, ingestion or skin contact with material may cause severe injury or death.

If inhaled, it can provoke coughing and nausea. [CHRIS] An epoxy resin hardener and suspected cause of occupational asthma, isophorone diamine is one component of mixtures causing occupational asthma in two separate documented cases: (1) [Occupational asthma due to EPO 60. Lambourn EM, Hayes JP, McAllister WA, Taylor AJ. Br J Ind Med 1992 Apr;49(4):294-5]; and (2) [Occupational asthma caused by a hardener containing an aliphatic and a cycloaliphatic diamine.

[ICSC] Danger of skin sensitization; [MAK] Causes burns; Inhalation may cause corrosive injuries to upper respiratory tract and lungs; Harmful by ingestion; [Aldrich MSDS]

ISOPHORONEDIAMINE is an amine. Amines are chemical bases. They neutralize acids to form salts. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides (Roger Patrick, DuPont Engineer). Corrodes aluminum and steel in the presence of moisture and carbon dioxide (USCG, 1999).

Excerpt from ERG Guide 153 [Substances - Toxic and/or Corrosive (Combustible)]:

Use water spray, powder, alcohol-resistant foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.

Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer immediately for medical attention.

Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer immediately for medical attention.

Rinse with plenty of water (remove contact lenses if easily possible). Refer immediately for medical attention.

Rinse mouth. Do NOT induce vomiting. Refer immediately for medical attention.

· CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper not available or no answer, refer to appropriate telephone number listed on the inside back cover.

· ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area.

INHALATION: Move victim to fresh air; call emergency medical care. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.

General First Aid:

SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.

Isophorone diamine (CAS # 2855-13-2) was evaluated for subchronic inhalation toxicity in male rats (10/dosage group, breed unspecified) administered whole-body exposures to nominal aerosol/vapor concentrations of 18, 200, and 550 mg/cu m, 6 hours/day for 9, 9, and 4 days, respectively. Following 9 exposures, 5 rats from each group (surviving numbers allowing) were sacrificed and necropsied, while the remaining were sacrificed after a subsequent 20-day recovery period. Treatment with 550 mg/m3 was associated with significantly reduced bodyweights and mean bodyweight gains and mortality (4/10) by completion of a fourth exposure, such that all surviving rats (6/10) of this group were sacrificed and necropsied with decedents following the fourth exposure. Dose-dependent histopathology was identified in the nose (18, 200, 550 mg/cu m), trachea (200, 550 mg/cu m), larynx (200, 500 mg/cu m), and lungs (200, 550 mg/cu m). Necrosis as well as hypertrophy/hyperplasia noted in the lungs and trachea of 4-day 550 mg/cu m rats and 9-day rats appeared resolved after 20-day recovery, as tissue repair was also apparent in the nose and larynx of these animals. The study report is summarized only and no further data are provided.

Basic treatment: Establish a patent airway. Suction if necessary. Watch for signs of respiratory insufficiency and assist ventilations if necessary. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for pulmonary edema and treat if necessary ... . Monitor for shock and treat if necessary ... . Anticipate seizures and treat if necessary ... . For eye contamination, flush eyes immediately with water. Irrigate each eye continuously with normal saline during transport ... . Do not use emetics. For ingestion, rinse mouth and administer 5 mg/kg up to 200 ml of water for dilution if the patent can swallow, has a strong gag reflex, and does not drool. Administer activated charcoal ... . Cover skin bums with dry sterile dressings after decontamination ... . /Organic bases/Amines and related compounds/

Advanced treatment: Consider orotracheal or nasotracheal intubation for airway control in the patient who is unconscious or has severe pulmonary edema. Positive-pressure ventilation techniques with a bag-valve-mask device may be beneficial. Monitor cardiac rhythm and treat arrhythmias as necessary ... . Start an IV with D5W /SRP: "To keep open", minimal flow rate/. Use lactated Ringer's if signs of hypovolemia are present. Watch for signs of fluid overload. Administer 1% solution methylene blue if patient is symptomatic with severe hypoxia, cyanosis, and cardiac compromise not responding to oxygen. ... . Consider drug therapy for pulmonary edema ... . For hypotension with signs of hypovolemia, administer fluid cautiously. If patient is unresponsive to these measures, vasopressors may be helpful. Watch for signs of fluid overload ... . Treat seizures with diazepam ... . Use proparacaine hydrochloride to assist eye irrigation ... . /Organic bases/Amines and related compounds/
