Exposure Routes: inhalation, skin absorption, ingestion, skin and/or eye contact Symptoms: Irritation eyes, skin, respiratory system; eye, skin burns; miosis, salivation, lacrimation (discharge of tears), twitching; Antabuse-like effects Target Organs: Eyes, skin, respiratory system, central nervous system (NIOSH, 2016)

Skin decontamination. Skin contamination with either the calcium salt or the free form should be removed by washing with soap and water. Flush eyes with copious amounts of clean water. If skin or eye irritation persists, medical attention should be obtained promptly. Calcium cyanamide

Use dry chemical or CO2 extinguishers. Containers may explode in fire. If material or contaminated runoff enters waterways, notify downstream users or potentially contaminated waters. Notify local health and fire officials and pollution control agencies. From a secure, explosion-proof location, use water spray to cool exposed containers. If cooling streams are ineffective (venting sound increases in volume and pitch, tank discolors or shows any signs of deforming), withdraw immediately to a secure position ... The only respirators recommended for fire fighting are self-contained breathing apparatuses that have full facepieces and are operated in a pressure-demand or other positive-pressure mode.

Excerpt from ERG Guide 154 [Substances - Toxic and/or Corrosive (Non-Combustible)]: Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. For electric vehicles or equipment, ERG Guide 147 (lithium ion batteries) or ERG Guide 138 (sodium batteries) should also be consulted. (ERG, 2016)

Use carbon dioxide, dry powder, dry sand, water spray. Combat fire from a sheltered position.

Personal protection: complete protective clothing including self-contained breathing apparatus. Do NOT let this chemical enter the environment. Vacuum spilled material with specialist equipment. Carefully collect remainder. Then store and dispose of according to local regulations.

Personal protection: complete protective clothing including self-contained breathing apparatus. Do NOT let this chemical enter the environment. Vacuum spilled material with specialist equipment. Carefully collect remainder. Then store and dispose of according to local regulations.

Spill handling: evacuate persons not wearing protective equipment from area of spill or leak until clean-up is complete. Remove all ignition sources. Ventilate area of spill or leak. Collect powdered material in the most convenient and safe manner and deposit in sealed containers. Absorb liquids in vermiculite, dry sand, earth, peat, carbon, or a similar material and deposit in sealed containers. It may be necessary to contain and dispose of this chemical as a hazardous waste. Keep cyanamide out of a confined space, such as a sewer, because of the possibility of an explosion, unless the sewer is designed to prevent the build-up of explosive concentrations. If material or contaminated runoff enters waterways, notify downstream users of potentially contaminated waters. Contact your Department of Environmental Protection or your regional office of the federal EPA for specific recommendations.

NO open flames. Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.

Separated from food and feedstuffs and incompatible materials. See Chemical Dangers. Cool. Store at maximum 20 °C, never exceed 30 °C. Dry. Well closed. Keep in a well-ventilated room. Store only if stabilized. See Notes. Store in stainless steel, polyethylene or polypropylene.The commercial 50% solution produced by Degussa AG is stabilized by a special buffer system to a pH between 4.0 and 4.6. Typically, it contains less than 1.5 % dicyandiamide, less than 0.5% urea, and less than 0.1 % thiourea. This solution is stable for at least 3 months if stored at a temperature below 20 deg C. Prolonged storage leads to an increase in the pH and thus to instability of the solution. If a pH of 5.2 has been reached, the product should be used quickly, above pH 5.5 it should be discarded immediately by mixing it with at least the double volume of water. Otherwise, a thermal runaway reaction leading to temperatures above 100 deg C and potential bursting of the container may occur.

The substance is a highly reactive compound. May explode on vacuum distillation. The substance may spontaneously polymerize. Dimerizes at temperatures above 40°C with strong heat release. Dimerization is catalyzed by traces of bases. Decomposes on contact with acids, bases or moisture. This produces toxic fumes including ammonia, nitrogen oxides and cyanides. Reacts with acids, strong oxidants and strong reducing agents. This generates explosion and toxic hazard. Attacks metals such as steel, copper and aluminium.

The storage life is at least 3 months at temperatures below 20 deg C. The product is packed in steel drums with polyethylene inliners. The packaging size is limited to 50 kg.

Cyanamide may burn, but does not readily ignite.CYANAMIDE is the amide of cyanic acid. Non-flammable but combustible (flash point: 140° C). Decomposes on warming above 49° C. Emits toxic fumes of CN- and NOx when heated to decomposition or on contact with acids or acid fumes (Hazardous Chemicals Desk Reference, p. 353 (1987)). Contact with moisture, acids or bases may cause a violent reaction at temperatures above about 40° C. Dry solid may polymerize at temperatures above 122° C. Rapid or explosive polymerization may occur during the evaporation of aqueous solutions. Reacts explosively with strong oxidizing agents and strong reducing agents. Attacks various metals (International Chemical Safety Card).

The substance is severely irritating to the eyes and skin. The substance is irritating to the respiratory tract. See Notes.

Repeated or prolonged contact may cause skin sensitization. Animal tests show that this substance possibly causes toxicity to human reproduction or development.

A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered.

AEROBIC: Initial concentrations of cyanamide ranging from 6.0 to 9.6 mg/L were found to decrease in three experiments using aerobic continuous-flow soil columns inoculated with activated sewage sludge and varying amounts of supplemental carbon (for example: columns receiving no supplement and columns receiving a supplement of sweet whey had a 10% and a 39.5% decrease, respectively, in cyanamide concentration between column influent and effluent). However, these results were similar to sterile columns run under the same conditions(1).

An estimated BCF of 3.2 was calculated in fish for cyanamide(SRC), using a log Kow of -0.80(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.

Using a structure estimation method based on molecular connectivity indices(1), the Koc of cyanamide can be estimated to be 4.7(SRC). The Koc of cyanamide can also be estimated as 7.3(SRC), using a log Kow of -0.82(2) and a regression-derived equation(1). According to a classification scheme(3), these estimated Koc values suggest that cyanamide is expected to have very high mobility in soil.

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.

Cyanamide has to be stabilized by pH-buffer against dimerization and decomposition.An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert.Cyanamide that has been stored for a long time or is contaminated, should be diluted with at least three times its volume of water to avoid critical decomposition temperatures being reached.Do NOT take working clothes home.Term cyanamide is also used to designate calcium cyanamide.In combination with even small amounts of alcohol the substance causes effects on cardiovascular and central nervous systems resulting in flushing, palpitation, hypotension and hyperventilation.
