Section 3 - HAZARDS IDENTIFICATION
Emergency Overview: This material is a clear, colorless liquid with a faint ammonia odor. Combustible
liquid and vapors. Harmful if ingested, inhaled, or absorbed through the skin. May
produce vapors or mists that can cause eye, skin, and respiratory tract irritation.
Prolonged or repeated exposure to vapors may cause drowsiness, nausea, dizziness,
or headaches. Toxic combustion products may be released under fire conditions.
Potential Health Effects From Overexposure: Possible routes of entry include skin & eye contact and process vapor or
mist inhalation.
Contact with liquid, vapors, or mists may cause irritation to the eyes, skin, nose, throat, and respiratory tract. May be
absorbed through skin. Inhalation of high vapor or mist concentrations may produce narcotic effects and unconsciousness.
Accidental ingestion may cause gastrointestinal irritation and may result in aspiration into the lungs causing chemical
pneumonia. Prolonged or repeated exposure may cause liver and reproductive effects. Processing under conditions of
inadequate ventilation may produce symptoms of drowsiness, nausea, dizziness, or headaches.
Appropriate precautions should be taken to minimize potential exposure to accidental ingestion, inhalation of process vapors
or mists, and skin contact.
Overexposure to decomposition or combustion products may cause irritation of the eyes, skin, and respiratory tract.
Symptoms such as coughing, tearing, and irritation should be regarded as potentially hazardous and measures taken to avoid
exposure. See Section 10 for information on combustion products.
Section 4 - FIRST AID MEASURES
If irritation occurs or persists from any route of exposure, remove the affected individual from the area and seek medical
assistance.
IIngestion: If swallowed, do not induce vomiting. Give large quantities of water. Never give anything by mouth to an
unconscious person. Seek medical assistance immediately.
Vapor Inhalation: Remove the affected individual to fresh air. If breathing has stopped, administer artificial respiration and
seek medical assistance immediately.
Eye Contact: Flush eyes with running water for several minutes while holding eyelids open. Consult a physician if irritation
persists.
Skin Contact: Remove contaminated clothing and shoes. Wash contact area with soap and water for 15 minutes. Seek
medical attention if irritation / allergic skin reaction develops. Launder contaminated clothing before reuse.
Section 5 - FIRE FIGHTING MEASURES
Extinguishing Media: Carbon dioxide, dry chemical, or alcohol resistant foam is recommended. Use water spray or fog to
extinguish surrounding fire, and cool fire exposed containers. Do not use halogenated extinguishing media.
Special Firefighting Procedures: Wear positive pressure self-contained breathing apparatus (SCBA) during the attack
phase of firefighting operations and during cleanup in enclosed or poorly ventilated areas immediately after a fire. Personnel
not having suitable respiratory protection must leave the area to prevent significant exposure to toxic combustion gases from
any source.
Unusual Fire and Explosion Hazards: Combustible liquid and vapors. Explosive vapor - air mixtures may form above the
flash point. Vapor can flow along surfaces to distant ignition sources and flash back. Closed containers may rupture due to
pressure buildup under fire conditions. Toxic gases may be formed upon combustion and represents a hazard to firefighters.
See Section 10 for additional information on combustion products.

Section 6 - ACCIDENTAL RELEASE MEASURES
Provide adequate ventilation. Remove all ignition sources. Wear respiratory protection and protective clothing to contain
spill. Use non-sparking tools in recovery operations. Contain and collect as much of the release as possible. Absorb
remaining residue with inert material and place into closed containers to await disposal. Do not allow product to enter
municipal sewers or waterways.
Section 7 - HANDLING AND STORAGE
Use only in well ventilated areas. Avoid contact with eyes, skin, and clothing. Store in a well ventilated location away from
heat, sparks, flame, and direct sunlight. Keep container closed when not in use. Evaluate transfer operations for potential
static charge buildup and ground and bond accordingly. Use non-sparking tools and equipment. Empty containers may retain
product residue (liquid and / or vapor) and can be dangerous. Do not pressurize, cut, weld, braze, solder, drill, grind, or
expose empty containers to heat, sparks, open flames, or incompatible materials.
Section 8 - EXPOSURE CONTROLS/PERSONAL PROTECTION
Ventilation: Enclose operations and / or provide local exhaust ventilation to draw fumes, vapors, or mists away from
workers. Ventilation must be adequate to maintain the ambient workplace atmosphere below the limits listed in Section 2.
Respiratory Protection: For protection against process vapors or mists, wear a NIOSH approved respirator suitable for the
anticipated airborne concentration. Wear a positive pressure air-supplied respirator in situations where there may be potential
for elevated airborne exposure.
Protective Equipment: During processing operations, splash proof goggles or safety glasses with face shield suitable for
keeping liquid material out of the eyes should be worn when potential exists for eye contact. Rubber gloves and apron should
be worn when skin contact is anticipated. Provide an eye wash facility and safety shower.

Section 12 - ECOLOGICAL INFORMATION
When released into the soil, DMAC is expected to leach into groundwater. This material is miscible in water and would be
expected to evaporate slowly when released to water. DMAC is not expected to significantly bioaccumulate. When released
to air, this material is expected to readily degrade by reaction with photochemically produced hydroxyl radicals. DMAC has
a half-life of less that 1 day.
Section 13 - DISPOSAL CONSIDERATIONS
Waste resulting from this product as supplied is not known to be classified as a hazardous waste per the current listings and
characteristics contained in 40 CFR Part 261, and its Appendices. It is the generator鈥檚 responsibility to determine, per the
regulation, the applicability of the Resource Conservation and Recovery Act (RCRA), as well as all state, local, or other
governmental agency waste disposal regulations, to the particular waste materials prior to treatment or disposal. Disposal of
liquid wastes and solids containing free liquids by land filling is prohibited in most jurisdictions. Incinerate or use biological
