Some 12 years ago or so, my vision got to the point where I needed reading glasses and then eventually I needed them all the time. Yesterday that turned out to be a real blessing! As I am always doing something that would require safety glasses, though they are more expensive, that's all I buy anymore and I wear the from the moment I awaken until I put them on my nightstand before turning out the light when I go to sleep.
Yesterday, I was spraying some 2-4-D to knock back some of the weeds growing in the lawn. When I got done, I still had 1/2 a tank of mixture, so I bled off the pressure. Afraid of having a lot of the mixture spray out needlessly, I turned the pump handle to release the pressure. I turned it too far and a big high pressure spray squirted the liquid up into my face. It did as I wanted release the pressure. Luckily, I had my safety glasses on when it happened. I confirmed the pressure was released, placed the tank sprayer in my shed, closed the door and went into the house. I quickly washed my face with soap rinsing it several times. Then I grabbed some clean clothes and showered.
Morale of the story....wear safety glasses or/or goggles and be careful!
