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 mL/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 buRNs with dry sterile dressings after decontamination . /Organic bases/Amines and related compounds/
SECTION 5: Firefighting measures
Suitable extinguishing media
Use water spray, dry chemical, "alcohol resistant" foam, or carbon dioxide. Use water spray to keep fire-exposed containers cool. Solid streams of water may be ineffective and spread material.
Specific hazards arising from the chemical
When heated to decomposition, it emits highly toxic fumes. Vapor may travel a considerable distance to source of ignition and flash back. Toxic oxides of nitrogen are produced during combustion. Nitric acid; reacts vigorously with oxiding materials. Stable, avoid physical damage, storage with oxidizing material. (EPA, 1998)
Special protective actions for fire-fighters
Use water in large amounts, powder, alcohol-resistant foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.
SECTION 6: Accidental release measures
Personal precautions, protective equipment and emergency procedures
Evacuate danger area! Personal protection: self-contained breathing apparatus. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.
Environmental precautions
Evacuate danger area! Personal protection: self-contained breathing apparatus. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.
Methods and materials for containment and cleaning up
Stop or control the leak, if this can be done without undue risk. Eliminate all ignition sources. Use water spray to cool and disperse vapors, protect personnel, and dilute spills to form nonflammable mixtures. Approach release from upwind. Absorb in noncombustible material for proper disposal.

Persistence and degradability
A 100% theoretical BOD was observed for 10 mg/l of cyclohexylamine in an acclimated sewage inoculum, plant sludge and river mud over a 14 day incubation period(1). The theoretical BOD of cyclohexylamine (50 mg/l) was 79%, 68 % and 0% in an acclimated sewage inoculum, plant sludge and river mud respectively over a 14 day incubation period(1). The theoretical BOD of cyclohexylamine (100 mg/l) was 79%, 0% and 0% in an acclimated sewage inoculum, plant sludge and river mud respectively over a 14 day incubation period(1). A 200 mg/l sample of cyclohexylamine could not be biodegraded by an activated sludge and was assumed to be toxic to the microflora(2). A theoretical oxygen demand between 25 and 45% was observed for cyclohexylamine in a Warburg apparatus during a 5 day incubation period(3).
Bioaccumulative potential
An estimated BCF of 3 was calculated for cyclohexylamine(SRC), using a log Kow of 1.49(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 cyclohexylamine is estimated as 150(SRC), using a measured log Kow of 1.49(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that cyclohexylamine is expected to have very high mobility in soil. The pKa of cyclohexylamine is 10.6(4), indicating that the protonated form will be the predominant species in moist soils and cations are expected to adsorb strongly to soil surfaces.
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.
