How and when should I perform safety interlock checks?

Interlocks should be checked for condition and function as part of the production or PM cycle. Condition to ensure they are structurally capable of use- no broken or worn components and that the safety interlock is secured to product/process -Function to ensure they activate shutdown safely and reliably as prescribed in the manual.

How do I know if I got a laser beam in the eye?

Most of the time, if you get hit in the eye with a laser beam, you will know it. A low power visible beam will cause you to finch and move your head away (“blink response” or “light aversion”). An intermediate or UV laser beam pulse or irradiation might show itself as pain and itching[…]

How and when do I check my laser goggles?

Laser eyewear must be checked for scratches and cracks before donning. Scratches can become more serious if deep enough, and are the first locations to fail (crack)- Cracks are especially worrisome because a crack is like the Grand Canyon to a Photon- Especially because the eye will still be dilated due to wearing the eyewear.[…]

Will one set of laser safety glasses work for all lasers in all our laboratories?

Typically no. While a specific pair of eyewear might indeed cover more than 1 wavelength, be within the same OD, offer the same damage threshold, and VLT within an optical setup or lab, each lab might contain different or varied sources. PPE migration is one of the leading causes of Photonics-based incidents and accidents.

Do I need an eye exam to operate a laser for my job?

Although according to ANSI Z136.1-2014 “Any employee with an actual or suspected laser-induced injury should be evaluated by a medical professional as soon as possible after the exposure (usually within 48 hours).” We suggest employees who will be working around Class III/3 and higher class lasers and/or UV sources of any type, obtain an eye[…]

How do I dispose of a laser no longer needed?

Depending upon: disposition (sale/transfer, destruction, or mothball) laser type configuration there are a number of issues you want to pay attention to including: dumping/discharging stored energy de-watering the system (from the head to re-circulation) relaxing/de-loading preloaded mechanical systems It is always best to refer to the documentation and/or contact the manufacturer for guidance

Do I need training to operate a laser?

According to ANSI Z136.1-2014: “Training shall be provided to each LSO and employee routinely working with or potentially exposed to Class 3B or Class 4 laser radiation. Training should be provided to employees working with or potentially exposed to Class 1M, Class 2, Class 2M or Class 3R laser radiation”. Note- this applies to safety[…]
