b)
Protective Regulations for Operating Lampheads In or Near Water:
• No other electrical equipment may be operated from the same junction.
• Make sure that the position of all electrical equipment and cables prevents electric shock from touch by persons
and animals at all times.
• All electrical equipment must be secured against falling into water.
• Cables must be placed at sufficient distance from water and must be securely fastened so that they cannot drop
or slide into water.
• You may place special cables through water if they are officially approved for this purpose.
• You can increase the safety of the environment by applying measures for preventing electrical danger as
described in section 1. b) of this leaflet.
c) Using Lampheads on Stands:
• Make sure that the stand is rated for the weight of the lamphead, including accessories and cables.
• Avoid lateral loads on the spigot when you set up and operate the lamphead, as they might cause the spigot to
suffer damage or to break.
• Stands that carry lampheads must be set up in a stable position. You should take additional measures to secure
stands if, for example:
- your setup location does not allow for stable positioning
- height restrictions interfere with stable positioning
- high winds are expected
- people might bump or push against the stand
Examples of suitable measures for securing stands are:
- fixating the stand with stage screws, e.g. stage or theatrical applications
-
weighing down the stand legs or feet, e.g. with sand bags
- tying the stand to stable objects
- fencing off the stand area
- positioning safety guards
- sufficient counterweight, when using boom stands
d) Operating Lampheads in Hanging Positions:
• Make sure that the hanging equipment is rated and dimensioned for the weight of the lamphead, including
accessories and cables.
• Avoid lateral loads on the spigot while you set up and operate the lamphead, as they might cause the spigot to
suffer damage or to break.
• Lampheads, including their accessories, must be protected against falling with the help of two independent safety
attachment points.
• If you are using additional accessories, make sure they are safely attached (e.g. self-tightening nuts, safety
latches, safety cables) or apply other suitable technical measures to prevent them from falling. Additional
accessories for stationary lampheads do not necessarily require added protection, as long as the lamphead
accessory holder is sufficiently rated for the extra load and the accessories are protected against self-loosening.
• For lampheads that are permanently attached to buildings the fastening must be specified to carry at least 5
times the weight of the lamphead. Lampheads fastened in a standing position must be secured in such a way as
to prevent a hazard from tilting if the fastening fails.
• In order to sufficiently secure lampheads the material selection and sizing of safety elements must fulfil the
requirements of the relevant regulations for suspending loads over people (for Germany BGI 810-3).
e) Lampheads in Special Environments:
• The use in explosive environment is not allowed.
• The use in corrosive atmosphere like salt water may require additional precaution.
• Please take appropriate precaution when using lampheads e. g. in an museum, historic building, church etc.
3.
Maintenance and Care
Please do not forget that the safe operation of lampheads also includes their maintenance and care.
A visual inspection should be conducted before every use, and an inspection of electrical safety should be conducted at
least once every 12 months. The results of these repeated inspections should be documented and filed.
You will find additional information for the setup and operation of your lamphead, as well as information on the special
features of the individual lamphead models, in the relevant operating instructions.
