It is very important for the safety of both laser users and those who are in the laboratory around laser based experiments, that laser safety policy is both understood and adhered to. This is not an onerous task as long as the rules are followed in a safe and sensible manner.

 

As a new user of either a class 3b or class 4 laser system, the Engineering Department requires that you undergo the following official laser user authorisation procedure.

University Laser Safety Guidance

The University Laser Safety policy is run by the Radiation Safety Office and covers both ionising and non-ionising (ie lasers, UV lamps, arc lamps and high bridghtness LEDs) sources of energy. The British Laser Safety Standards provide a suitable framework upon which to build a suitable laser safety policy. The University Health and Safety Division have produce a series of guidelines: Safe Use of Lasers (third edition)[PDF, 368KB] . This booklet contains information for Departmental Laser Safety Officers, laser users and research supervisors. Contact the departmental laser safety officer for copies of this booklet.

The Safe Use of Lasers guide provides basic essential information for working safely with lasers. For additional advice on laser safety please consult your Research Supervisor, Departmental Laser Safety Officer or the Assistant Radiation Protection Officer (University Health and Safety Division). Section A of the booklet contains information especially relevant to users of Class 3B and 4 lasers, section B gives specific information which may be useful in various applications and section C contains appendices for additional information. Generally, as a minimum, Class 3B and 4 laser users should read section A in addition to local policy and procedure documents.

 

For any one using class 3b or class 4 laser(s), the following steps MUST be followed.

Local rules for laser installations in the Engineering Department

The procedure listed above is designed to assist in the process of setting up and risk assessing a new or existing laser based experiment or piece of equipment. Please note these rules apply to all of the satellite laboratories around the Cambridge area as well as the main Trumpington St site. This includes sites such as the Whittle labs, The Gates Building, CAPE, IfM and the the centifuge labs.

The following rules apply to anyone who is setting up an system which uses or includes a Class 3b or Class 4 laser or a light source of equivalent power lever (such as UV lamp or high brightness LED). If you are not sure what class your laser or light source is, then contact the departmental laser safety officer to discuss possible classifications. Even if you are using a laser classified lower than 3b, it is worth getting touch to discuss any possible risks or hazards.

 

Resource list

A list of useful sources of laser safety equipment such as eyewear, filter material, IR/UV viewers, etc. Please contact the departmental laser safety officer or the Health and Safety Division if you have anything to add to this list and we will update it.
