Lead, copper or their alloys; amines, strong alkalis, strong acids.

HAZARDOUS DECOMPOSITION PRODUCTS

Oxides of carbon and nitrogen.

HAZARDOUS POLYMERIZATION WILL NOT OCCUR.

SPILL OR LEAK PROCEDURES

STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED

Evacuate area and remove potential sources of spark or flame.
Properly protected personnel may then attempt to contain large spills and pump to salvage.
Absorb unrecoverable spills with an inert solid such as sand or earth.
Flush area with water.

DISPOSAL METHOD:
Incinerate, or bury in an approved sanitary landfill.

HEALTH HAZARD DATA

THRESHOLD LIMIT VALUE
(PERMISSABLE EXPOSURE LIMIT):
100 ppm (TLV and PEL)

EFFECTS OF OVEREXPOSURE

Liquid:
Prolonged exposure can lead to mild irritation due to "defatting".
Only slightly toxic by ingestion.

Vapor:
Headache, nausea, vomiting, narcosis.
Extremely Irritating to eyes, burning sensation when close to a running Nitro Engine!
Warning: Chronic overexposure may cause liver and kidney damage.

FIRST AID

EYE:
Nonirritating method: Flush eyes with water for 15 minutes.

SKIN:
Wash exposed skin with soap and water.
Launder clothing wet with NM before reuse.

INHALATION:
Remove to fresh air.
Call a physician, who may check for increased methemoglobin content.

INGESTION:
Induce vomiting by giving victim 2 glasses of water and having him place a finger down the throat.

PROTECTIVE EQUIPMENT

VENTILATION:
General ventilation with local exhaust in areas of high vapor concentration.

RESPIRATORY PROTECTION:
Air-supplied respiration or self-contained breathing apparatus.
Do not use canister type face masks.

PROTECTIVE CLOTHING:
Rubber gloves and aprons.

EYE PROTECTION:
Safety glasses.

OTHER SPECIAL PRECAUTIONS

PRECAUTIONS TO BE TAKEN IN HANDLING AND STORAGE:
Keep away from heat and flame. Keep container closed. Store only in original container. Protect from energy impacts.

SPECIAL COMMENTS: Use only with adequate ventilation.
