■ Any time your employee must select a different respirator such as when a previously selected respirator fails a test

– Select and follow at least one of the following fit test procedures:

■ Qualitative fit-test procedures:

♦ Saccharine aerosol in Table 13

♦ Bitrex™ aerosol in Table 14

♦ Irritant smoke in Table 15

1	The Rainbow Passage:
	"When the sunlight strikes raindrops in the air, they act like a prism and form a rainbow. The rainbow is a division of white light into many beautiful colors. These take the shape of a long round arch, with its path high above, and its two ends apparently beyond the horizon. There is, according to legend, a boiling pot of gold at one end. People look, but no one ever finds it. When a man looks for something beyond reach, his friends say he is looking for the pot of gold at the end of the rainbow."
