Explanation

Section 3395(d)(1) requires the shade to be open to the air or provided with ventilation or cooling, located as close as practicable to the work, and large enough for everyone on a recovery or rest period to sit in a normal posture fully in the shade without physical contact with one another. The definition in subsection (b) disposes of (a): shade is blockage of direct sunlight, but it is not adequate when the heat in the shaded area defeats the purpose of shade, and the standard's own example is a car sitting in the sun, which does not count unless it is running with air conditioning. There is no fixed distance (b) - 'as close as practicable' adapts to the site. And the capacity is everyone on the break, not a fraction of them (d).
