Type of SOP: ☐ Process ☒Hazardous Chemical ☐ Hazardous Class
Purpose
It has been investigated for use as an oxidizer in bipropellant rockets, however its high freezing temperature makes it unsuitable. Highly purified tetranitromethane cannot be made to explode, but its sensitivity is increased dramatically by oxidizable contaminents, such as anti-freezing additives. This makes it effectively unusable as a propellant. In the laboratory it is used a reagent for the detection of double bonds in organic compounds and as a nitrating reagent. It has also found use as an additive to diesel fuel to increase the cetane number.
Physical & Chemical Properties/Definition of Chemical Group
CAS#: 509-14-8
Class: Suspect Carcinogens
Molecular Formula: CN4O8
Form (physical state): liquid
Color: pale yellow
Boiling point: 126 oC
Potential Hazards/Toxicity
· Accute Health Effects: Irritating to the skin and eyes on contact. Inhalation will cause irritation to the lungs and mucus membrane. Irritation to the eyes will cause watering and redness. Reddening, scaling, and itching are characteristics of skin inflammation. Follow safe industrial hygiene practices and always wear protective equipment when handling this compound. May be fatal if inhaled, swallowed, or absorbed through skin. Causes eye irritation. Causes skin irritation. Absorption into the body leads to the formation of methemoglobin, which in sufficient concentration causes cyanosis. Onset may be delayed 2 to 4 hours or longer. Can cause CNS depression.
· Chronic Health Effects: Carcinogen. Damage to the heart Damage to the eyes
· Accute Health Effects: This product is listed by NTP (Sufficient evidence of carcinogenicity from studies in experimental animals) and OSHA (Suspected Human Carcinogen: Agent is carcinogenic in experimental animals at dose levels, by route(s) of administration, at site(s), of histology type(s), or by mechanism(s) considered relevant to worker exposure. Available epidemiological studies are conflicting or insufficient to confirm an increased risk of cancer in exposed humans) as suspected human carcinogen.

Personal Protective Equipment (PPE)
Respirator Protection
Where risk assessment shows air-purifying respirators are appropriate use a full-face respirator with multi-purpose combination (US) or type ABEK (EN 14387) respirator cartridges as a backup to engineering controls. If the respirator is the sole means of protection, use a full-face supplied air respirator. Use respirators and components tested and approved under appropriate government standards such as NIOSH (US) or CEN (EU)...
Respirators should be used only under any of the following circumstances:
· As a last line of defense (i.e., after engineering and administrative controls have been exhausted).
· When Permissible Exposure Limit (PEL) has exceeded or when there is a possibility that PEL will be exceeded.
· Regulations require the use of a respirator.
· An employer requires the use of a respirator.
· There is potential for harmful exposure due to an atmospheric contaminant (in the absence of PEL)
· As PPE in the event of a chemical spill clean-up process
Lab personnel intending to use/wear a respirator mask must be trained and fit-tested by EH&S. This is a regulatory requirement. http://www.asu.edu/ehs/documents/asu-respiratory-protection-plan.pdf
Hand Protection
Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique (without touching
glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in
accordance with applicable laws and good laboratory practices. Wash and dry hands..
NOTE: Consult with your preferred glove manufacturer to ensure that the gloves you plan on using are compatible with tetranitromethane
Refer to glove selection chart from the links below:

Eye Protection
Face shield and safety glasses Use equipment for eye protection tested and approved under appropriate
government standards such as NIOSH (US) or EN 166(EU)..
Skin and Body Protection
Complete suit protecting against chemicals, The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace..
Hygiene Measures
Handle in accordance with good industrial hygiene and safety practice. Wash hands before breaks and at the end of
workday.
Engineering Controls
Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below recommended exposure limits. If user operations generate dust, fume or mist, use ventilation to keep exposure to airborne contaminants below the exposure limit.
First Aid Procedures
If inhaled
If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention.
In case of skin contact
After contact with skin, wash immediately with plenty of water. Gently and thoroughly wash the contaminated skin with running water and non-abrasive soap. Be particularly careful to clean folds, crevices, creases and groin. Cold water may be used. Cover the irritated skin with an emollient. If irritation persists, seek medical attention.
In case of eye contact
Check for and remove any contact lenses. In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Cold water may be used. Get medical attention immediately.
If swallowed
Do not induce vomiting. Loosen tight clothing such as a collar, tie, belt or waistband. If the victim is not breathing, perform mouth-to-mouth resuscitation. Seek immediate medical attention.
Special Handling and Storage Requirements
Storage Temperatures: Store at ambient temperature Shelf Life:Unlimited in tightly closed container. Special Sensitivity: None Handling/Storage Precautions:Avoid breathing dust. Avoid getting in eyes or on skin. Wash thoroughly after handling. Store in a dry place away from direct sunlight, heat and incompatible materials (see Section X). Reseal containers immediately after use. Store away from food and beverages. .
Spill and Accident Procedure
Chemical Spill Dial 911 and 480-965-1823
Spill – Assess the extent of danger. Help contaminated or injured persons. Evacuate the spill area. Avoid breathing vapors. If possible, confine the spill to a small area using a spill kit or absorbent material. Keep others from entering contaminated area (e.g., use caution tape, barriers, etc.).
Small (<1 Liter) – Follow the “Hazardous Materials Incident” guidance in the posted Emergency Response Guide.
Large (>1 Liter) – Dial 911. Follow guidance for major spill or leak in the posted Emergency Response Guide
Chemical Spill on Body or Clothes – Remove clothing and rinse body thoroughly in emergency shower for at least 15 minutes. Seek medical attention. Notify supervisor and ASU EH&S at 480-965-1823.
