All buildings have ventilation — the way air moves in and out. But in many factories, bad ventilation harms workers’ health by not moving air containing chemicals, dust, and heat out of the factory.

The factory owner is responsible for protecting you and the air you breathe by:

  • making sure all workers have clean, fresh air in the factory.
  • reducing the risk of exposure for workers and people in surrounding communities by using fewer chemicals and less of each one, and replacing harmful chemicals with less harmful ones.
  • changing tools, machines, chemicals, and work processes so they produce less fumes and less dust.
  • preventing the buildup of chemicals, dust, and heat and safely removing them from the factory.
  • keeping the factory at a comfortable temperature (see Chapter 15: Heat and cold) and giving workers enough breaks and clean water to drink.
