I want to share what I hope may bring awareness to how many fumes we inhale off the push mower, line trimmer and blower, on an average day. I fear some of us feel sickish but may not make the connection with exhaust fumes. I don't think anyone is immune to exhaust but how do you know how it affects you and when its beginning to have an affect on your body. I've run chain saws for years and never wore a vapor mask. All the mowers and tillers and concrete saws and continuous exposure has left me super sensitive. It's important to know that any exposure to fossil fuel exhaust fumes is unacceptable. Would you hang out behind your car with the engine running ? I think not. Exposure over time builds up with continual use of gas powered equipment. Protect yourself from the parts you CANNOT see. That's all for now. Rj Brooks
