| FIRST
AID MEASURES |
| Eyes: |
Check for contact lenses & remove if present. Flush
eyes with copious amount of water for at least 15 minutes. Call for
medical attention if irritation persists. |
| Inhalation: |
In emergency situations use proper respiratory protection &
immediately remove the victim from exposure. Administer artificial
respiration if breathing has stopped. Keep at rest & call for
medical attention. |
| Skin: |
Flush with copious amounts of water. Use soap if available. Remove
contaminated clothing (including shoes) & launder before re-use. In
case of frostbite from contact with liquid, immediately place affected
area in lukewarm water & keep at this temperature until circulation
returns. If inflammation or irritation develops, seek medical attention. |
| Ingestion: |
Not likely to occur. |
| PREVENTATIVE
MEASURES |
| Personal Protection: |
Select PPE depending on conditions.
In open systems where contact is likely,
wear gas-proof goggles, face shield, chemical resistant overalls &
appropriate thermal/chemical gloves.
Where skin & eye contact is unlikely,
wear long sleeves, chemical resistant gloves & gas-proof goggles.
Where concentrations in air may exceed the
occupational exposure limits & where engineering, work
practices or other means of exposure reduction are not adequate,
approved respirators may be necessary to prevent overexposure by
inhalation. Respiratory protection must be NIOSH/MSHA approved &
conform to OSHA rules specified in 29 CFR 1910-134. |
| Engineering Controls: |
Use only in well-ventilated situations or employ extraction
ventilation to maintain atmospheric concentrations well below exposure
standards. All mechanical equipment used in ventilation systems must be
spark proof. |
| Spill/Disposal Procedure: |
Eliminate all sources of ignition. Prevent additional discharge of
material if possible to do so without hazard. Warn occupants in downwind
areas. Disperse vapors with hose streams using fog nozzles. Ensure
disposal complies with government requirements & ensure conformity
to local disposal regulations. Notify the appropriate authorities
immediately. |
| Handling, Storage & Shipping: |
Store in a cool, well-ventilated place away from incompatible
materials. Do not allow cylinder temperature to exceed 130°F (54°C).
Cylinders that are not in use must have the valves in the closed
position & be equipped with a protective cap. Transport & store
cylinders secured in an upright position in a ventilated space. Use
proper grounding procedures. |

| Hazardous Combustion Products: |
Carbon dioxide, acrid fumes |
| Sensitivity to Mechanical Impact: |
Mixture not sensitive, protect cylinders from damage. |
| Sensitivity to Static Discharge: |
Vapors may ignite if exposed to static discharge. |
| Fire & Explosion Hazard: |
Flammable air vapor mixtures may form if allowed to leak to
atmosphere. Accumulation of gas is an ignition hazard. Vapors are
heavier than air & may travel to an ignition source. Flashback along
vapor trail may occur. |
| Fire Extinguishing Precautions: |
Use water spray or fog to cool exposed cylinders. Do not extinguish
flames unless leak can be stopped. Fire can be extinguished with carbon
dioxide and/or dry chemical. |
| NFPA HAZARD CLASSIFICATION: |
|
| Health: |
1 = Materials that, on exposure, would cause irritation, but only
minor residual injury even if no treatment is given. |
| Flammability: |
4 = Materials which will rapidly or completely vaporize at atmospheric
pressure & normal ambient temperature, or which are readily
dispersed in air & which will burn readily. The preferred method of
fire attack is to stop the flow of material or to protect exposures
while allowing the fire to burn itself out. |
| Reactivity: |
0 = This degree includes materials that are normally stable, even
under fire exposure conditions, & that do not react with water.
Normal fire fighting procedures may be used. |
| REACTIVITY
DATA |
| This material is stable. Hazardous
Polymerization will not occur. |
| Incompatibility: |
Nickel carbonyl with oxygen, chlorine, and strong
oxidizers. |
| Conditions to avoid: |
Avoid excessive heat and/or static discharge. Gas
explodes spontaneously when mixed with chlorine dioxide. |
| Hazardous Decomposition: |
Thermal decomposition & burning may produce carbon
dioxide & or acrid fume. |
