Dear Mr. Rapin:

This is in response to your recent letter, regarding the hazardous components of diesel engine emission. I apologize for the delay in responding to your inquiry.

One of the components in diesel engine emissions is carbon monoxide. The Occupational Safety and Health Administration (OSHA) standard for carbon monoxide (CO) is 50 parts per million of air. The adverse health effects of exposure to carbon monoxide are asphyxiation, and anoxia.The symptoms of acute CO poisoning are headache, dizziness, drowsiness, nausea, vomiting, collapse, coma, and death.

Diesel engine exhaust emissions also contain sulfur dioxide (SO2). OSHA's permissible exposure limit for SO2 is 5 parts SO2 per 1 million parts air. Exposure to SO2 may result in broncho-constriction, fatigue, altered sense of smell, and the symptoms of chronic bronchitis.

It is impossible to tell if your place of employment is in compliance with OSHA's permissible exposure limits for any air contaminant without taking air samples.

We encourage you to contact the OSHA area office having jurisdiction over your locality to discuss your specific concerns about diesel emissions, air quality in your workplace and adverse health effects. The address and telephone number are as follows:
[Diane Brayden

If we may be of further assistance regarding this matter, feel free to contact us.

Dear Sir

I am in need of information on the exhaust emission from diesel engines. If I can't convince my union or my company that it isn't safe to breathe these fumes 8 hours a day I may lose my job after 27 years and 7 years short of retirement.

I understand that a couple of employees have went to the doctor but I see no point. After one days lose I have trouble breathing for weeks afterward. If the company & the union don't believe me I doubt if a local "pill pusher" will.

Somewhere there must be information on this but I can't find it. Any information you can give will be gratefully received.

Yours truly

Alfred C. Rapin
