MSDS Name:N-Methyl-N-nitroso-p-toluenesulfonamide (Not currently sold)
Synonym:N-Methyl-N-nitroso-p-toluenesulfonamide; p-Tolylsulfonylmethylnitrosamide; N-Nitroso-N-methyl-4-tolylsulfonamide; Toluene-p-sulfonylmethylnitrosamide; Diazogen; diazomethane precursor

EMERGENCY OVERVIEW
Risk of explosion by shock, friction, fire or other sources of ignition. Irritating to eyes, respiratory system and skin. May cause sensitization by skin contact. Heating may cause an explosion.Hygroscopic (absorbs moisture from the air).
Potential Health Effects
Eye:
Causes eye irritation.
Skin:
Causes skin irritation. May cause skin sensitization, an allergic reaction, which becomes evident upon re-exposure to this material.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and diarrhea.
Inhalation:
Causes respiratory tract irritation.
Chronic:
May cause reproductive and fetal effects. Nitrosamines have been found to be carcinogens in laboratory animals.

Eyes: Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.
Skin:
Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Get medical aid if irritation develops or persists.
Ingestion:
Call a poison control center. If swallowed, do not induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to an unconscious person. Get medical aid.
Inhalation:
Remove from exposure and move to fresh air immediately. Get medical aid if cough or other symptoms appear.
Notes to Physician:

General Information:
As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. This material is an explosion hazard when exposed to heat, mechanical shock, or friction.
Extinguishing Media:
Use water fog, dry chemical, carbon dioxide, or regular foam.

General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks:
Wash area with soap and water. Clean up spills immediately, observing precautions in the Protective Equipment section. Sweep up, then place into a suitable container for disposal. Avoid generating dusty conditions. If the material is dry, explosives experts may be necessary to dispose of the spill.

Handling:
Wash thoroughly after handling. Use with adequate ventilation. Avoid contact with eyes, skin, and clothing. Avoid ingestion and inhalation. Inform laundry personnel of contaminants hazards. Avoid percussion and friction.
Storage:
Store in a cool, dry place. Do not store in direct sunlight. Keep refrigerated. (Store below 4C/39F.) Keep container closed when not in use.

Engineering Controls:
Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower. Use adequate general or local explosion-proof ventilation to keep airborne levels to acceptable levels.
Exposure Limits CAS# 80-11-5: Personal Protective Equipment Eyes: Wear chemical splash goggles and face shield.
Skin:
Wear appropriate gloves to prevent skin exposure.
Clothing:
Wear appropriate protective clothing to prevent skin exposure.
Respirators:
Follow the OSHA respirator regulations found in 29 CFR 1910.134 or European Standard EN 149. Use a NIOSH/MSHA or European Standard EN 149 approved respirator if exposure limits are exceeded or if irritation or other symptoms are experienced.
