Compliance Checklist for entertainment laser

|NIR |Description |Compliance |Remarks |

| | | | |

| | | | |

|A |For outdoor laser event, has approval been obtained from SPF, CAAS and MINDEF? (Also see H1) |Yes / No | |

| | | | |

| | | | |

|B |A floor plan of the event, showing the location of the lasers and the path of the laser beams is submitted together with this checklist. (Also |Yes / No | |

| |see H2.) | | |

|C1 |Laser light shows are under the direct and personal supervision of the N3 licensee. |Yes / No | |

|C2 |There will be a N3 licensee present at all times to operate the laser during the laser show. |Yes / No | |

|C3 |In this event, every laser operator shall hold a valid N3 licence. |Yes / No | |

|D1 |The laser system, including projector, has been rigidly mounted to prevent unintended movement or accidental misalignment. |Yes / No |34(7) |

|D2 |Scanning devices of the laser system have incorporated an automatic means to turn off the beam or to prevent laser emission in case the beam |Yes / No |34(9) |

| |stops scanning or slows down significantly. | | |

| | | | |

| |In cases where a mirror ball is used with a scanning beam, the limits in Point D3 below shall be met with the mirror ball stationary; or the | | |

| |mirror ball shall incorporate an automatic means to turn off the beam or to prevent laser emission if the mirror ball stops rotating or slows | | |

| |down significantly such that the limits of Points D3 or D4 are exceeded. | | |

| | | | |

| |Any such scan failure safeguard system shall have a reaction time fast enough to preclude audience access to levels in excess of Class 1. | | |

|D3 |Levels of laser and collateral radiation, measured where the audience is normally located, and laser and collateral radiation measured where the |Yes / No |34(13) |

| |operators, performers and employees are located if the radiation is intended to be viewed by them, shall not exceed the limits of Class 1 during | | |

| |operation. Radiation which shall be measured includes reflections from targets and scattering materials. | | |

|D4 |Operators, performers and employees shall be able to perform their functions without the need for exposure to laser and collateral radiation in |Yes / No |34(14) |

| |excess of the limits of Class 2 when the radiation is not intended to be viewed by them. | | |

| | | | |

| |Areas where levels of laser radiation in excess of the limits of Class 2 exist shall be clearly identified by posting a sign or by the use of | | |

| |barriers or guards or both to prevent entry of operators or performers into these areas. | | |

|D5 |The laser beam to which human access can be gained shall not exceed the limits of Class 2 at any points: |Yes / No |34(10) |

| |(a) less than 3.0 m above any surface upon which the audience or general public is permitted to stand; and | | |

| |(b) less than 2.5 m in lateral separation from any position where a person in the audience or general public is permitted during the performance| | |

| |or display, unless physical barriers are present which obstruct access by the audience or general public to such levels. | | |

|E1 |There will be a designated individual present who can immediately turn off and secure the laser systems in case of unsafe operating conditions |Yes / No |34(12) |

|E2 |The designated individual in Point E1 hold a valid N3 licence. |Yes / No | |

|E3 |Every laser operator is situated in a position such that the performers, the audience, beam path and laser display can be viewed by the laser |Yes / No |34(15) |

| |operator at all times during the laser operation. | | |

|F1 |All safety devices necessary to comply with Points D2 to D5, such as scanning-beam power interlock, are functionally tested and recorded before |Yes / No |34(17) |

| |each laser light show. | | |

|F2 |Where the laser output is limited to less than the maximum power available in order to comply with Points D2 to D5, the laser output power will |Yes / No |34(16) |

| |be measured, adjusted and recorded before it is operated at each laser light show. | | |

|G1 |Every laser system is secured against unauthorised operation. |Yes / No |34(18) |

|G2 |The following precautions are being taken during alignment procedures: |Yes / No |34(19) |

| | | | |

| |(a) alignment shall be performed with the laser radiation emission reduced to lowest practicable level; | | |

| |(b) only persons who are required to perform alignment shall be in or near the beam path; and | | |

| |(c) protective eyewear shall be worn where necessary to prevent hazardous exposure. | | |

|H1 |In the case of open air shows where a laser beam is projected into the sky, the information submitted will also include beam spot size, beam |Yes / No |34(21) |

| |divergence and beam power measured at the projector. | | |

|H2 |Before a laser light show is permitted to operate either at a permanent or temporary job site, the licensee will provide RPNSD with sufficient |Yes / No |34(30) |

| |information, data and measurements to establish that all the relevant requirements of these Regulations shall be complied with during use. | | |

| | | | |

| |(This shall include sketches showing the locations of audience or general public, laser, mirror balls and other reflective or diffuse surfaces | | |

| |which may be struck by laser beam, scanning beam patterns, scanning velocity and frequency in occupied areas where beam strikes wall or other | | |

| |structure, and radiometric measurement data including output power and location of all measurements.) | | |
