C. Purks Avon Lake Tech Center The attached DuPont MSDS's are returned for clarification. Your computer database indicates H-7 and H-8 are trimethylamine and dimethylamine with no indication of solution. Information previously provided by you indicates H-8 is a 40% solution of dimethylamine and H-7 is 100% trimethylamine. Can you provide us the correct chemical identity of H-7 and H-8?

These compounds are corrosive to skin and eyes. Toxic effects described in animals from exposure by inhalation, ingestion, or skin contact include corrosion, of mucous membranes, central nervous system effects, liver effects, and nonspecific effects such as weight loss, and irritation. Dimethylamine in tests in bacterial or mammalian cell cultures demonstrated no mutagenic activity.
"Inhalation, absorption, and ingestion data are for the amines on a 100% basis.

PHYSICAL DATA (cont'dl Human health effects of overexposure may initially include: skin irritation with discomfort or rash on contact; eye irritation with discomfort, tearing, or blurring of vision on contact; or irritation of the upper respiratory passages on inhalation. Higher exposures may lead to these effects: skin burns or ulceration; eye corrosion with corneal or conjunctival ulceration on contact; or temporary lung irritation effects with cough, discomfort, difficulty breathing, or shortness of breath on inhalation. There are no reports of human sensitization.
CARCINOGENICITY MMA, DMA, and TMA are not listed as carcinogens by IARC, NTP, OSHA, or ACGIH.
EXPOSURE LIMITS [PEL (OSHA), TLV (ACGIH), AEL (DU PONT), ETC.] The OSHA 8-hour Time Weighted Average (TWA) and ACGIH TLV^-TWA are:
MMA - 10 ppm or 12 mg/m*; DMA - 10 ppm or 18 mg/m*; TMA - 10 ppm or 24 mg/m* (the OSHA and ACGIH Short Term Exposure Limit (STEL) for TMA is IS ppm or 36 mg/m*). The AIHA WEEL 8-hour TWA is 1 ppm; the Du Pont recommended 8- and 12-hour airborne exposure limit is S ppm, TWA. All limits are for amines on a 100% basis.
SAFETY PRECAUTIONS Do not get in eyes; on skin, on clothing. Do not breathe gas or vapors. Wash thoroughly after handling.
FIRST AID In case of contact: Immediately flush eyes or skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Call a physician. Wash clothing and shoes before reuse.
If vapors are inhaled: Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Call a physician.
If swallowed: Do not induce vomiting. Immediately give two glasses of water or activated charcoal slurry. Never give anything by mouth to an-unconscious person. Call a physician.
Note: To prepare activated charcoal slurry, suspend 50 gms. activated charcoal in 400 mL of water in a bottle and shake well.
PROTECTION INFORMATION
GENERALLY APPLICABLE CONTROL MEASURES Good general ventilation should be provided to keep vapor concentrations below exposure limits.
PERSONAL PROTECTIVE EQUIPMENT Have available and wear as appropriate: hard hat with brim; safety spectacles (side shields preferred); chemical splash goggles; full length face shield; rubber gauntlet gloves, apron, safety boots or boots over leather shoes; self-contained breathing apparatus or full face air-line respirator; complete rubber suit with hood and breathing air supply.
