NICKEL AMMONIUM SULFATE

Nickel ammonium sulfate is a green crystalline solid. Mildly toxic, carcinogenic. When heated to decomposition it emits highly toxic fumes of metallic nickel, oxides of sulfur, and oxides of nitrogen (Lewis, 3rd ed., 1993, p. 910). The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. It is used for electroplating nickel.

Water soluble. Forms an acidic aqueous solution.

Special Hazards of Combustion Products: Toxic oxides of nitrogen may be formed in fire. (USCG, 1999)

Inhalation causes irritation of nose and throat. Ingestion causes vomiting. Contact with eyes causes irritation. Contact with skin may cause dermatitis. (USCG, 1999)

NICKEL AMMONIUM SULFATE is a "double salt" that is a weak oxidizing agent. Gives an acidic solution when dissolved in water.

Excerpt from ERG Guide 171 [Substances (Low to Moderate Hazard)]:

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 171 [Substances (Low to Moderate Hazard)]:

CAUTION: Fire involving Safety devices (UN3268) and Fire suppressant dispersing devices (UN3559) may have a delayed activation and a risk of hazardous projectiles. Extinguish the fire at a safe distance.

SMALL FIRE: Dry chemical, CO2, water spray or regular foam.

LARGE FIRE: Water spray, fog or regular foam. Do not scatter spilled material with high-pressure water streams. If it can be done safely, move undamaged containers away from the area around the fire. Dike runoff from fire control for later disposal.

FIRE INVOLVING TANKS: 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. (ERG, 2024)

Excerpt from ERG Guide 171 [Substances (Low to Moderate Hazard)]:

Do not touch or walk through spilled material. Stop leak if you can do it without risk. Prevent dust cloud. For Asbestos, avoid inhalation of dust. Cover spill with plastic sheet or tarp to minimize spreading. Do not clean up or dispose of, except under supervision of a specialist.

SMALL DRY SPILL: With clean shovel, place material into clean, dry container and cover loosely; move containers from spill area.

SMALL SPILL: Pick up with sand or other non-combustible absorbent material and place into containers for later disposal.

LARGE SPILL: Dike far ahead of liquid spill for later disposal. Cover powder spill with plastic sheet or tarp to minimize spreading. Prevent entry into waterways, sewers, basements or confined areas. (ERG, 2024)

Bu. Mines approved respirator; rubber gloves; face shield or safety goggles; protective clothing (USCG, 1999)

No information available.

INHALATION: move to fresh air; get medical attention if exposure has been severe.

INGESTION: give large amount of water.

EYES: flush with water for at least 15 min.; get medical attention if irritation persists.

SKIN: wash with soap and water. (USCG, 1999)
