How to treat the risk of Cyclohexane

Cyclohexane is a cycloalkane with the molecular formula C6H12. Cyclohexane is used as a nonpolar solvent for the chemical industry, and also as a raw material for the industrial production of adipic acid and caprolactam, both of which being intermediates used in the production of nylon. 

On an industrial scale, cyclohexane(CAS NO.: 110-82-7) is produced by reacting benzene with hydrogen. Producers of cyclohexane account for approximately 11.4% of global demand for benzene. Because of its unique chemical and conformational properties, cyclohexane is also used in labs in analysis and as a standard. Cyclohexane has a distinctive detergent-like odor, reminiscent of cleaning product .

Cyclohexane is extremely flammable liquid and vapor. Vapor may cause flash fire. Breathing vapors may cause drowsiness and dizziness. Aspiration hazard if swallowed. It can enter lungs and cause damage. It may cause eye and skin irritation. 

Potential Health Effects and first measure

Eye: Cyclohexane may cause mild eye irritation. Vapors may cause eye irritation. In case of contact, immediately flush eyes with plenty of water for a t least 15 minutes. Get medical aid. 

Skin: it may cause irritation with burning pain, itching and redness. Not expected to cause an allergic skin reaction. A single prolonged skin exposure is not likely to result in the material being absorbed in harmful amounts. In case of contact Cyclohexane, flush skin with plenty of water. Remove contaminated clothing and shoes. Get medical aid if irritation develops and persists. Wash clothing 
before reuse.

Ingestion: Aspiration of material into the lungs may cause chemical pneumonitis, which may be fatal. It may cause central nervous system depression. Potential for aspiration if swallowed. Get medical aid immediately. Do not induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to an unconscious person. 

Inhalation: it may cause respiratory tract irritation. Inhalation of vapors may cause drowsiness and dizziness. If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid. 

Chronic: Prolonged or repeated skin contact may cause defatting and dermatitis.Treat symptomatically and supportively. 

Fire Fighting Measures

General Information: As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use water spray to keep fire-exposed containers cool. Liquid will float and may reignite on the surface of water. Extremely flammable liquid and vapor. Vapor may cause flash fire. Vapors are heavier than air and may travel to a source of ignition and flash back. Vapors can spread along the ground and collect in low or confined areas. 

Extinguishing Media: Water may be ineffective. Cyclohexane is lighter than water and insoluble in water. The fire could easily be spread by the use of water in an area where the water cannot be contained. Do NOT use straight streams of water. For large fires, use water spray, fog or regular foam. For small fires, use dry chemical, carbon dioxide, water spray or regular foam. Cool containers with flooding quantities of water until well after fire is out.
