Most important symptoms/effects, acute and delayed
Excerpt from ERG Guide 156 [Substances - Toxic and/or Corrosive (Combustible / Water-Sensitive)]: TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. Contact with molten substance may cause severe burns to skin and eyes. Reaction with water or moist air will release toxic, corrosive or flammable gases. Reaction with water may generate much heat that will increase the concentration of fumes in the air. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution. (ERG, 2016)
Indication of immediate medical attention and special treatment needed, if necessary
Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. Isocyanates, aliphatic thiocyanates, and related compounds
SECTION 5: Firefighting measures
Suitable extinguishing media
If material on fire or involved in fire: Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not bur or burns with difficulty.) use water in flooding quantities as fog. Use foam, dry chemical, or carbon dioxide. Keep run-off water out of sewers and water sources.
Specific hazards arising from the chemical
Excerpt from ERG Guide 156 [Substances - Toxic and/or Corrosive (Combustible / Water-Sensitive)]: Combustible material: may burn but does not ignite readily. Substance will react with water (some violently) releasing flammable, toxic or corrosive gases and runoff. When heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapors may travel to source of ignition and flash back. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water. (ERG, 2016)
Special protective actions for fire-fighters
Use powder, carbon dioxide.
SECTION 6: Accidental release measures

SECTION 10: Stability and reactivity
Reactivity
The substance polymerizes under the influence of temperatures above 93°C. On combustion, forms toxic and corrosive fumes including nitrogen oxides and hydrogen cyanide (see ICSC 0492). Decomposes on contact with water. This produces amine and polyureas. Reacts violently with acids, alcohols, amines, bases and oxidants. This generates fire and explosion hazard. Attacks copper.
Chemical stability
no data available
Possibility of hazardous reactions
HEXAMETHYLENE DIISOCYANATE reacts with water. Base-catalyzed reactions of this compound with alcohols may be explosively violent in the absence of diluting solvents. This chemical is incompatible with strong bases, amines, acids and strong oxidizers. It is also incompatible with metal compounds and surface active materials. (NTP, 1992).
Conditions to avoid
no data available
Incompatible materials
Base-catalyzed reactions of isocyanates such as hexamethylene diisocyanate with alcohols should generally be carried out in inert solvents. Such reactions in the absence of solvents often occur with explosive violence.
Hazardous decomposition products
When heated to decomposition it emits toxic fumes of /nitrogen oxides/.

Bioaccumulative potential
Hexamethylene diisocyanate reacts readily with water to form amines and polyureas(1-3); therefore, bioconcentration of monomeric hexamethylene diisocyanate in aquatic organisms is not expected to be an important environmental fate process(SRC).
Mobility in soil
Hexamethylene diisocyanate reacts readily with water to form amines and polyureas(1-3); therefore, adsorption of monomeric hexamethylene diisocyanate in soil is not expected to be an important environmental fate process(SRC).
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.

Other Information
The symptoms of asthma often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential.Anyone who has shown symptoms of asthma due to this substance should avoid all further contact.Anyone who has shown skin sensitization due to this substance should avoid all further contact.Workers exposed to this compound may also be sensitized to other isocyanates.The odour warning when the exposure limit value is exceeded is insufficient.Do NOT take working clothes home.
