Eye Protection
Make sure there is no damage anywhere on this equipment before use. Cracks and gaps can allow dangerous and high-speed objects to reach your eyes. If there is a strap, ensure it is tied securely to avoid the glasses dropping from the safe position during use. If there are traditional over-ear glasses supports instead of a strap, make sure they are not loose or damaged.
For use with dangerous chemicals, hot fluids, sparks, dust, metal filings and other hazardous materials. Just ensure that your eyes are properly covered from all sides and that the glass or plastic viewing section at the front is clear, before operating machinery. If the viewing section is dirty, broken or excessively scratched, it could impair your vision or render the protection ineffective.
