Chemical Properties

4,40 -Methylenebis (2-chloroaniline) is a yellow to light gray-tan pellet and is also available in liquid form.

Potential Exposure

4,40 -Methylenebis(2-chloroaniline) is used as a curing agent in the polyurethane industry for isocyanate containing polymers; in the production of solid elastomeric parts. Other uses are in the manufacture of crosslinked urethane foams used in automobile seats and safety padded dashboards; it is also used in the manufacture of gun mounts; jet engine turbine blades; radar systems; and components in home appliances. Incompatibilities: Reacts with chemically active metals e.g., potassium, sodium, magnesium, and zinc). May ignite on contact with cellulose nitrate of high surface area. Incompatible with acrolein, acrylonitrile, tert-butyl nitroacetylene; ethylene oxide; isopropyl chlorocarbonate; maleic anhydride, triisobutylaluminum.

First aid

If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Seek medical attention immediately. Ifthis chemical has been inhaled, remove from exposure,begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medicalfacility. When this chemical has been swallowed, get medical attention. Give large quantities of water and inducevomiting. Do not make an unconscious person vomit.Note to Physician: Treat for methemoglobinemia.Spectrophotometry may be required for precise determination of levels of methemoglobin in urine.

storage

Color Code—Blue: Health Hazard/Poison: Storein a secure poison location. Prior to working with thischemical you should be trained on its proper handling andstorage. 4,40-Methylenebis(2-chloroaniline) must be storedto avoid contact with chemically active metals (such aspotassium, sodium, magnesium and zinc), since violentreactions occur. Store in tightly closed containers in a cool,well-ventilated area. A regulated, marked area should beestablished where this chemical is handled, used, or storedin compliance with OSHA Standard 1910.1045.

Shipping

UN2811 Toxic solids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required

Incompatibilities

Reacts with chemically active metals(e.g., potassium, sodium, magnesium, and zinc). May igniteon contact with cellulose nitrate of high-surface area.Incompatible with acrolein, acrylonitrile, tert-butyl nitroacetylene, ethylene oxide, isopropyl chlorocarbonate, maleicanhydride, triisobutylaluminum.

Short Term Exposure

4,40-Methylenebis(2-chloroaniline)can affect you when breathed in and by passing throughyour skin. 4,40-Methylenebis(2-chloroaniline) is a carcinogen; handle with extreme caution. Exposure can interferewith the ability of the blood to carry oxygen causing headaches, dizziness, nausea, and a bluish color to the skin andlips. High levels can cause trouble breathing, collapse, anddeath. Contact can irritate the eyes. High or repeated exposures may affect the kidneys, cause a low blood count, andcause bloody urine.

Long Term Exposure

May cause methemoglobinemia,anemia, kidney irritation. A potential occupational carcinogen. May affect the kidneys

Personal Protective Methods

Wear protective gloves andclothing to prevent any reasonable probability of skin contact: 8 h: Saranex coated suits, Barricade coated suits.4 h: 4H and Silver Shield gloves. Safety equipment suppliers/manufacturers can provide recommendations on themost protective glove/clothing material for your operation.All protective clothing (suits, gloves, footwear, headgear)should be clean, available each day, and put on beforework. Contact lenses should not be worn when workingwith this chemical. Wear dust-proof chemical goggles andface shield unless full face-piece respiratory protection isworn. Employees should wash immediately with soap whenskin is wet or contaminated. Provide emergency showersand eyewash.

Fire Extinguishing

This chemical is a combustible solid.Use dry chemical, carbon dioxide, water spray, or alcoholfoam extinguishers. Poisonous gases, including chlorine andnitrogen oxides, are produced in fire. If material or contaminated runoff enters waterways, notify downstream users ofpotentially contaminated waters. Notify local health and fireofficials and pollution control agencies. From a secure,explosion-proof location, use water spray to cool exposedcontainers. If cooling streams are ineffective (venting soundincreases in volume and pitch, tank discolors, or shows anysigns of deforming), withdraw immediately to a secure position. If employees are expected to fight fires, they must betrained and equipped in OSHA 1910.156. The only respirators recommended for firefighting are self-containedbreathing apparatuses that have full face-pieces and areoperated in a pressure-demand or other positive-pressuremode
