Level 1 Training (November 12)
Stage Crew Level 1 Training
Rubix Sometime in 2012
Level 1 Training (November 12)
Safe use of Cables
Level 1 Training (November 12)
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
Level 1 Training (November 12)
Electrical Safety
Level 1 Training (November 12)
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
Level 1 Training (November 12)
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
Level 1 Training (November 12)
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
Level 1 Training (November 12)
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.
Level 1 Training (November 12)
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
Level 1 Training (November 12)
Water water everywhere!
− Water and electricity mix.
− Keep drinks and beer away from the kit− Even a small shock can be deadly
Level 1 Training (November 12)
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
Level 1 Training (November 12)
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.
Level 1 Training (November 12)
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

What not to do…
Level 1 Training (November 12)
Manual Handling
Level 1 Training (November 12)
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
Level 1 Training (November 12)
Other H&S
• COSHH• Noise Levels• Strobes• Pyrotechnics• Alcohol• First Aid• Workshop• PPE• Recycling

Fire
Level 1 Training (November 12)
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.
Level 1 Training (November 12)
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
Level 1 Training (November 12)
Fire Extinguishers
• CO2 :
– Use on electrical fires or flammable liquids
• Foam:– Everything else!
