General Description

A fine green powder. Slightly soluble in water and denser than water. Primary hazard is threat to the environment. Immediate steps should be taken to limit spread to the environment.

Hazards

Reactivity Alerts

none

Air & Water Reactions

Slightly soluble in water.

Fire Hazard

Special Hazards of Combustion Products: None known

Behavior in Fire: Converts to black nickelic oxide (Ni 2 O 3 ). (USCG, 1999)

Health Hazard

INHALATION: Irritant to mucous membrane of upper respiratory tract. EYES: Irritant to conjunctiva. SKIN: May cause sensitization. Sensation of burning or itching, followed by erythema and nodular eruption-fingers, wrists, and forearms. (USCG, 1999)

Reactivity Profile

NICKEL HYDROXIDE is a light-green crystalline material, moderately toxic, carcinogenic. When heated to decomposition it emits toxic fumes of metallic nickel [M. K.].

Belongs to the Following Reactive Group(s)

Response Recommendations

Isolation and Evacuation

Excerpt from 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 car or tank truck 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, 2020)

Firefighting

Excerpt from 171

[Substances (Low to Moderate Hazard)]:

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 engulfed in fire. (ERG, 2020)

Non-Fire Response

Excerpt from 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, 2020)

Protective Clothing

NIOSH-approved respiratory protection, side shield safety glasses or goggles, and rubber gloves. (USCG, 1999)
