Safety
Because the infrared light used in communications can not be seen, there is a potential laser safety hazard to technicians. In some cases the power levels are high enough to damage eyes, particularly when lenses or microscopes are used to inspect fibers which are inadvertently emitting invisible IR. Inspection microscopes with optical safety filters are available to guard against this.
Small glass fragments can also be a problem if they get under someone's skin, so care is needed to ensure that fragments produced when cleaving fiber are properly collected and disposed of appropriately.

Famous quotes containing the word safety:
“Once women begin to question the inevitability of their subordination and to reject the conventions formerly associated with it, they can no longer retreat to the safety of those conventions. The woman who rejects the stereotype of feminine weakness and dependence can no longer find much comfort in the cliché that all men are beasts. She has no choice except to believe, on the contrary, that men are human beings, and she finds it hard to forgive them when they act like animals.”
—Christopher Lasch (b. 1932)
“Love no man in good earnest, nor no further in sport
neither, than with safety of a pure blush thou mayst in
honor come off again.”
—William Shakespeare (1564–1616)
“... what a family is without a steward, a ship without a pilot, a flock without a shepherd, a body without a head, the same, I think, is a kingdom without the health and safety of a good monarch.”
—Elizabeth I (1533–1603)
