Striations in Dust on the Walls
Ben is almost finished up grinding the plaster and floors. This creates a lot of dust so they wear dust masks, goggles, hats, gloves and suits. They look like a hazmat team. The suites keep their cloths, somewhat, clean. Hats keep the dust out of their hair. Goggles out of their eyes and most importantly, the high quality full face dust masks keep the dust out of their lungs.
The dust isn’t toxic or anything like that but it is a fine particulate matter which we don’t want to be breathing. Silicosis is no, cough-cough-cough, laughing matter. This was a disease suffered by a lot of the stone workers in the local quarries and carving sheds here in Vermont back before they understood how bad it was and what to do about it. We take safety very seriously.
We also use special shrouds around the grinders to capture the dust and a powerful dust collector to evacuate the air from the rooms so that fresh air is coming into the work space.
Still, the dust sticks to everything in the work space. There was a very thick carpet of it on the floor, until Ben vacuumed it up this morning revealing the beautiful floor. It also sticks to vertical surfaces like the walls as shown in the photo above and even to the ceilings.
What is of particular interest is that the dust on the walls is in striations running vertically. Can you figure out why? I figured it out. For a clue see this post.
