Diamond	Hazard	Value	Description
0 3 0	Health	3	Can cause serious or permanent injury.
	Flammability	0	Will not burn under typical fire conditions.
	Instability	0	Normally stable, even under fire conditions.
	Special

A white powder. Insoluble in water. Toxic by inhalation (dust and the hydrogen cyanide from slight decomposition) and by ingestion. Produces toxic oxides of nitrogen in fires. Used in medicine, in metal plating, and in chemical analysis.

none

Insoluble in water.

Excerpt from ERG Guide 151 [Substances - Toxic (Non-Combustible)]:

Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Containers may explode when heated. Runoff may pollute waterways. (ERG, 2024)

EYES: Causes eye burns. SKIN: Irritation. INGESTION OR INHALATION: A bitter, acrid burning taste is sometimes noted followed by a feeling of constriction or numbness in the throat. Salivation and nausea are not unusual, but vomiting is rare. Anxiety, confusion, vertigo, giddiness and often a sensation of stiffness in the lower jaw. Hypernea and dyspnea. Rapid respiration, then slow and irregular. Unconsciousness, convulsions, death from respiratory arrest. (USCG, 1999)

ZINC CYANIDE is decomposed by acids to give off hydrogen cyanide, a flammable poisonous gas. Tends to explosive instability. Capable of violent oxidation under certain condition; fusion with metal chlorates, perchlorates, nitrates or nitrites can cause explosions [Bretherick, 1979 p. 101]. Reacts with incandescence with magnesium [Mellor, 1940, Vol. 4, 271].

Excerpt from ERG Guide 151 [Substances - Toxic (Non-Combustible)]:

IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids.

SPILL: Increase the immediate precautionary measure distance, in the downwind direction, as necessary.

FIRE: If tank, rail tank car or highway tank is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2024)

Excerpt from ERG Guide 151 [Substances - Toxic (Non-Combustible)]:

SMALL FIRE: Dry chemical, CO2 or water spray.

LARGE FIRE: Water spray, fog or regular foam. If it can be done safely, move undamaged containers away from the area around the fire. Dike runoff from fire control for later disposal. Avoid aiming straight or solid streams directly onto the product.

FIRE INVOLVING TANKS, RAIL TANK CARS OR HIGHWAY TANKS: Fight fire from maximum distance or use unmanned master stream devices or monitor nozzles. Do not get water inside containers. Cool containers with flooding quantities of water until well after fire is out. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks in direct contact with flames. For massive fire, use unmanned master stream devices or monitor nozzles; if this is impossible, withdraw from area and let fire burn. (ERG, 2024)

Excerpt from ERG Guide 151 [Substances - Toxic (Non-Combustible)]:

Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. Prevent entry into waterways, sewers, basements or confined areas. Cover with plastic sheet to prevent spreading. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. DO NOT GET WATER INSIDE CONTAINERS. For solids, prevent dust cloud and avoid inhalation of dust. (ERG, 2024)

Approved dust respirator, air or oxygen mask in emergencies, chemical safety goggles, dry cotton gloves for handling solids and rubber gloves for solutions, hard hat or brimmed felt hat, rubber or leather safety shoes, long sleeved shirt. (USCG, 1999)

EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.

SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment.

INHALATION: IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. IMMEDIATELY call a physician and be prepared to transport the victim to a hospital even if no symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used; if not available, use a level of protection greater than or equal to that advised under Protective Clothing.

INGESTION: CYANIDES ARE EXTREMELY TOXIC AND FAST-ACTING POISONS. Even though the induction of vomiting is not usually recommended outside of a physician's care if the victim is conscious and not convulsing, it may be worth the risk if a cyanide has been ingested. Ipecac syrup or salt water may be used to induce vomiting in such an emergency. IMMEDIATELY call a hospital or poison control center and transport the victim to a hospital. If the victim is convulsing or unconscious, do not give anything by mouth, assure that the victim's airway is open and lay the victim on his/her side with the head lower than the body. DO NOT INDUCE VOMITING. IMMEDIATELY transport the victim to a hospital. (NTP, 1992)
