Health Hazard
Excerpt from NIOSH Pocket Guide for Nickel metal and other compounds (as Ni):

Exposure Routes: Inhalation, ingestion, skin and/or eye contact

Symptoms: Sensitization dermatitis, allergic asthma, pneumonitis; [potential occupational carcinogen]

Target Organs: Nasal cavities, lungs, skin

Cancer Site: Lung and nasal cancer (NIOSH, 2024)
Reactivity Profile
NICKEL is not highly reactive in bulk. A reducing agent. Reacts with (is corroded by) acids to generate flammable hydrogen. Burns when heated in oxygen. Incompatible with oxidizing agents such as oxidizing acids, ammonium nitrate, chlorine, potassium perchlorate, nitryl fluoride. Powdered nickel is much more reactive; can ignite in air [Bretherick 1979 p. 170-171].

Protective Clothing
Excerpt from NIOSH Pocket Guide for Nickel metal and other compounds (as Ni):

Skin: PREVENT SKIN CONTACT - Wear appropriate personal protective clothing to prevent skin contact.

Eyes: No recommendation is made specifying the need for eye protection.

Wash skin:
� WHEN CONTAMINATED - The worker should immediately wash the skin when it becomes contaminated.
� DAILY - The worker should wash daily at the end of each work shift, and prior to eating, drinking, smoking, etc.

Remove: WHEN WET OR CONTAMINATED - Work clothing that becomes wet or significantly contaminated should be removed and replaced.

Change: DAILY - Workers whose clothing may have become contaminated should change into uncontaminated clothing before leaving the work premises. (NIOSH, 2024)

First Aid
Excerpt from NIOSH Pocket Guide for Nickel metal and other compounds (as Ni):

Skin: WATER FLUSH IMMEDIATELY - If this chemical contacts the skin, immediately flush the contaminated skin with water. If this chemical penetrates the clothing, immediately remove the clothing and flush the skin with water. Get medical attention promptly.

Breathing: RESPIRATORY SUPPORT - If a person breathes large amounts of this chemical, move the exposed person to fresh air at once. If breathing has stopped, perform artificial respiration. Keep the affected person warm and at rest. Get medical attention as soon as possible.

Swallow: MEDICAL ATTENTION IMMEDIATELY - If this chemical has been swallowed, get medical attention immediately. (NIOSH, 2024)
