Laser users: A laser user is a person who has had only basic laser safety awareness training, and is not yet competent enough to be designated a laser operator. They may only use restricted lasers when a laser supervisor is present. Users are normally inexperienced students or staff. Visitors: A visitor is any person lawfully entering a workplace, who is not authorised to use or operate lasers or any other machinery or plant within.
Visitors must not be put at risk by workplace activities. This person is required to be knowledgeable in the evaluation and control of laser hazards, and is responsible for overseeing the control of laser hazards at the University.

Duties of the LSO include, but are not limited to, the following:. Approving the acquisition of any restricted laser for the University regardless of whether the laser is purchased, hired, borrowed, gifted, manufactured, converted, etc. Providing information and specialist advice on laser management and operation as requested or required. Conducting periodic inspections of laser laboratories and other workplaces where restricted lasers are being used to verify compliance with the laser safety standard. Coordinating and conducting investigations of laser incidents involving serious harm or notifiable events including serious eye injuries, serious burns, and fires.
People using lasers must be trained to a level that reflects their role and the level of risk associated with the lasers being used, in accordance with the laser competency matrix. Laser Safety Awareness training is an in-house course usually delivered by the LSO, while lab inductions and training on specific restricted lasers are conducted on an individual basis by laser supervisors.
If used under normal operational conditions and without modification e. Restricted lasers pose a high risk to users and others if not properly controlled. Elimination - remove the exposure of the worker to harmful laser energy by totally enclosing the laser. This is the most preferred of all the controls and should be used wherever possible. Substitution- remove the exposure of the worker to harmful laser energy by using a less powerful laser to accomplish the task.
Isolation through engineering - minimise the risk of harm by isolating a person from a high risk laser laser controlled areas, beam guides and curtains. Minimisation through personal protective equipment laser safety goggles, glasses, and appropriate clothing. Where required, these activities must be recorded.
When guards, covers, or other integral protective devices are removed or otherwise defeated during maintenance, power sources must be removed, isolated or locked out so that a laser is not able to be started using the power buttons or in alternative, other controls must be in place. All disposals of restricted lasers must be conducted in consultation with the laser safety officer. Restricted lasers that are to be sold or gifted to a third party must meet the following requirements:.
- Laser Worker Safety Training - Online - UW Research?
- Secondary menu.
- Primer on Kidney Diseases.
- A Map of Glass.
- Laser hazards.
Where such items are offered for scrap to a third party, a declaration is to state that the machinery or item of plant is only to be used for scrap. Hazard refers to anything that has the potential to cause harm injury or ill-health or damage to property or equipment in connection with a work activity.

Note that some machinery such as laser cutters and engravers may incorporate embedded high risk lasers; as long as the safeguards are intact, the machine may be categorised as an unrestricted laser product. Maximum permissible exposure MPE. The level of laser radiation to which a person may be exposed without hazardous effect or adverse biological changes to the eyes or skin.
Exposure levels should be maintained as far below the MPE values as is practicable. Plant is a general name for machinery, equipment, appliances, implements or tools and any component or fitting or accessory of these. Note that some items of plant such as blu-ray players, laser microscopes and spectrometers may incorporate embedded high risk lasers; as long as the safeguards are intact, the item of plant may be categorised as an unrestricted laser product. Risk refers to the likelihood a hazard will cause harm injury or ill health and the degree of harm consequence.
Residual risk is the risk that remains after controls have been applied to a hazard. The most requested tasks include:. See the resources section of this site for detailed information of laser safety requirements applicable to laser product manufacturers. C provides training and consulting services on the health and safety requirements and standards applicable to laser users. Most regulatory agencies that have authority over laser users either refer to, or have adopted all or in part, the ANSI Z series of laser safety standards, or IEC series of technical reports for creating a safe work environment.
Hazard evaluation, which includes calculating Maximum Permissible Exposures MPE , hazard distances, optical density requirements, and material damage thresholds. Assistance in complying with the U. Assistance in complying with U. Provide recommendations for compliance with state, provincial, and local requirements.
