Level 1 Training (November 12)

Stage Crew Level 1 Training

Rubix Sometime in 2012


Safe use of Cables


Cable & Cable Runs

•Many different types of cable and connector

•Make sure you use the right one for the job – if you’re not sure, ask!

•Think about cable runs

−Trip hazards

−Damage to cable

−Securing cables

•Cables are expensive

•Coil them before putting away


Electrical Safety


Electricity in the Entertainment Industry

Nearly all aspects of work carried out by members of Stage Crew will involve electricity in some way. In most cases quite a lot of electricity.

Electrical Policy•Electricity at work act means we have to have strict procedures•Regular electrical testing•Maintenance•BS7671/A1 & BS7909:2011

Typical Power Supplies•National Grid or Generators•Single Phase 230V/50Hz up to 125Amp ~ 29kW (495x60W light bulbs)•Three Phase 400V/50Hz up to 400Amp ~ 92kW (1,533x60W light bulbs)

•Single Phase 110V/50Hz up to 16Amp


Electrical Protection

• Electrical safety devices

− Fuses – must be replaced to restore power after a fault

− Miniature Circuit Breakers (MCBs) – resettable after a fault

− Residual Current Devices (RCDs) – protect against electric shock, find out what happened before resetting

− You – plan and label everything you do, make sure you know what is connected to what before turning anything on

• Interlock sockets:

− Can only be switched on with a plug inserted

− Plug can only be inserted/removed when switched off


Current Capacity & Splitters

• Be aware of roughly how much current a device draws− Equipment that draws a lot of current needs a fat cable

− Using a thin cable could cause a fire risk

• Splitter cables

− Just because it is physically possible to connect many things into one hole it

doesn’t mean that it is necessarily electrically safe

− Splits are limited by the lowest rated connector


Before Use Check List

CHECKS SHOULD INCLUDE LOOKING TO SEE THAT:

there is an in-date electrical safety sticker present;both the plug and socket are intact (and present);there is no damage to the cable resulting in exposed conductors;the outer sheath of the cable makes it all the way into both the plug and the socket and seams firmly attached; andthere are no obvious burn marks.


Not happy?

• Isolate• Remove the item from use• Make sure someone else doesn’t use it again

• Label• Use sparky tape and a sharpie• Write what the problem is clearly• Try not to be too cryptic in your descriptions

• Report• Tell someone else that you have found a problem


Water water everywhere!

− Water and electricity mix.

− Keep drinks and beer away from the kit− Even a small shock can be deadly


Water water everywhere!

− Water and electricity DO mix - extremely well!

− Keep drinks and beer away from the kit− Even a small shock can be deadly


What to do in case of electric shock

1. Do not touch the casualty until you have switched off the mains supply or removed the plug.

• If you cannot switch off the supply, stand on something dry and insulating, and push the casualty away from the source of power using a dry wooden implement.

• Ensure that there is no further danger of electric shock to yourself or others

• Call a first aider.

• Report the incident to the senior crew member present and the House Officer.

• Fill out an Incident Report Form.


Further Training

Level 2 Electrical Training

•After Level 2 training, you will be able to…−Make cables−Test electrical equipment−Repair cables and equipment

•Until then…−If you see something you feel is unsafe, don’t wait for someone else to remove it, do it there and then.−Ask people for advice or to check what you’ve done if you’re not sure−Alert people to something you think could be unsafe


Sound


Rigging


Rigging

• Clamps & Couplers

• Safeties

• Static & Dynamic loads

• Spansets, Shackles & Steels

• Stands

• Rope

• Vibration

Staging

Drapes&


Staging & Drapes

• Staging• Handrails• Bracing• Attaching deck together• Suitability for use

• Drapes• Fireproofing• Lights and vents• Taking care of drapes• Tying/hanging


Lighting


Working at Height


What not to do…


Manual Handling


Manual Handling

• Solo lifting– Use your knees, not your back– Make sure you know what you’re lifting– Don’t be afraid to ask

• Broken crew can’t do much!

• Group Lifting– Make sure everyone knows what’s going where and in

what way– Don’t join in if you haven’t been invited

• Wheeling– Mind out for things on the floor– Cases can tip over easily if top heavy– Take care on ramps


Other H&S

• COSHH• Noise Levels• Strobes• Pyrotechnics• Alcohol• First Aid• Workshop• PPE• Recycling


Fire


On Hearing the Alarm…

• Announcement through the PA– If in Rubix, this is automatic

– If elsewhere, the sound engineer should make an announcement

• Leave the building via the nearest exit

• Turn off sound and lighting power only if on the way out

• Meet at the assembly point, encouraging others to follow you

• If you are feeling useful, grab a fluorescent jacket from backstage and help Union Staff encourage people towards the assembly points.


On Discovering a Fire…

• Raise the alarm!– Use break-glass buttons around the venue

• Leave the building via the nearest exit

• If you route is blocked by fire, find another way out

AND

• If you are comfortable doing so, use an appropriate fire extinguisher


Fire Extinguishers

• CO2 :

– Use on electrical fires or flammable liquids

• Foam:– Everything else!
