49
Q

If you need to cross the line, what do you do before you cross?

A

-make sure there’s sufficient sighting distance and no trains
are approaching
-go straight across without stepping on rails or sleepers
-take care near points - your foot could get trapped
-check there is a position of safety on the opposite site.

On lines with conductor rails:

  • find a gap or a place where protective guarding is provided
  • step over the running rail and conductor rail together.
50
Q

What does a group need when working or walking on or near the line?

Q

In the SSOW, what does Seperated site of work mean?

A

A Separated Site of Work is safe if it is a minimum of 2m (6fti6in) from the line. If there are more than two people in the group, a Site Warden must be appointed to give a warning of any danger.

If you are working on a Separated Site of Work and hear the Site Warden’s warning (either a verbal shout of ‘Get back!’ or a series of short blasts on a whistle or horn), you must stop work and make sure you are still within the safety limits of the work area.

Space is provided between the site of work and the nearest open line. The boundary of the work area
depends on the size of the group and whether a Site Warden is appointed.

The boundary of the work area:

  • At least 2 metres with 1 or 2 people, a site warden is not needed.
  • At least 2 metres with more than 2 people, a site warden is needed.

  • tell the other person your name, employer, job title, location and contact number
  • explain what has happened, the location and what action needs to be taken
  • check that the other person has understood your message and ask them to repeat it back to you
  • wait for further instructions.
74
Q

Whenever you commmunicate by phone or radio, what should you make sure?

A

Use the phonetic alphabet for difficult words or names and say numbers on digit at a time.

75
Q

How do you make sure your message is understood?

A
  • With the mouthpiece close to your mouth (but not too close)
  • Directly into the mouthpiece
  • Slightly slower than normal, with a natural rhythm
  • At the same volume as you would in normal conversation. You must always:
  • Use clear sentences
  • Use normal railway words and phrases found in the rules, regulations and instructions
  • Use the phonetic alphabet – to check your message is understood correctly
  • Try to avoid hesitation sounds (for example, ‘um’ or ‘er’) and slurring one word into another
  • If the other person responds or speaks in an accent or dialect which is unfamiliar, take time to make sure your message is understood and that you understand his or her message.
76
Q

What phrases do you use when using a radio or telephone?

A

‘This is an emergency call.’ This message conveys information which requires immediate action to prevent death, serious injury or damage.

‘Repeat back.’ Repeat all of the message back to me

‘Correction.’ I have made a mistake and will now correct the word or phrase just said

77
Q

What phrases to use when using a radio and only one person can be heard at a time.

A

‘Over.’ I have finished my message and am expecting a
reply

‘Out.’ I have finished my message and I do not expect
a reply

Do not use phrases such as ‘not clear’ or ‘not safe’ to describe a line that is unsafe.
Always use the phrase ‘line blocked’ to describe a line which is blocked to trains.

78
Q

Why do you need to be a certain distance apart from a moving train?

A

The slipstream can pull you into the tracks, leading to a fatal injury

79
Q

What is a close call?

A

NWR defines a close call as anything that has the potential to cause harm or damage

80
Q

What is included in a ‘close call’?

A

The potential to:
• Harm a person - this includes minor and major injuries, and fatalities
• Harm the environment and/or protected species
• Damage railway infrastructure, plant, vehicles, tools, equipment, systems
and information

81
Q

What should you do if you see a close call?

A

You should first see if you can deal with the issue yourself.
If not, then raise it with the COSS.
If they don’t resolve it, then you need to report it using Close Call.

82
Q

When reporting a close call what should you do?

A

Only use your phone from a position of safety once the COSS
has given their permission for you to do so.

Take a photo and submit a Close Call if the safety concern won’t cause any risks
or hazards that day but may potentially in the future.

If this is the case, you can raise your concern via Close Call,
but be sure to let the COSS know before doing so.

83
Q

When you see a close call, when do you raise it?

A

ASAP

84
Q

Name 4 safety reporting channels

A

Close Call - report safety concerns early
• Speak Out - report issues of a personal or reputation nature
• Take 5 - perform a quick safety check to assess a concern
• CIRAS - report concerns confidentially

85
Q

How far away should you be from a live Direct Current Conductor Rail?

A

You must aways be at least 30cm/1 foot away along with tools and equipment

86
Q

When an on-track plant or machine is on the track what has to be put in place?

A

An exclusion zone that must not be entered unless authorised by a Machine Controller(MC) or Crane Controller (CC). This is because the operators have blind spots.

87
Q

Where and when do safety briefings

take place?

A

Safety briefings take place in a position of safety, before accessing the line.

88
Q

What will a coss check for in the briefing

A

Check your ppe and sentinel card

89
Q

What is a blocked line?

A

A blocked line means that there is no train expected on that line

90
Q

What is a MEWP

A

Mobile Elevated Working Platform

91
Q

Who do you report any task-related safety issues to?

A

Person In Charge (PIC)

92
Q

What is a runaway?

A
This is where a vehicle or piece of equipment accidentally becomes detached, then runs away until it
loses its momentum or hits something.
Some examples of rail plant that could potentially runaway:
• OTP
• OTMs
• Hand trolleys
• Trailers
• Wagons
93
Q

Name some more potential dangers of the railway.

A

Underfoot conditions are less dangerous but most likely to cause slips, trips and falls.
Uneven ground within the cess, raised tracks, cabling and equipment are some of the more common
hazards to watch out for when you’re on or near the line.
Manual handling incidents can also be dangerous, and just as likely to happen.
When lifting and moving equipment, always use the correct methods and tools. And always use support
if you need it.

94
Q

What are the possible risks of an MEWP

A
  • Standing on the frame rather than the platform
  • Not being appropriately harnessed to the platform
  • Working at an unsafe height
  • Working with a hooded top on
95
Q

You’re attending a safety briefing from the Controller of Site Safety (COSS) and part way through hear some words and phrases you don’t understand. What would be the best thing to do here?

A

Checking as soon as possible would be the best option. However, that isn’t always possible, so the next best approach would be to wait until the end of briefing when the COSS checks for questions.

Never ignore something you don’t understand, but asking a colleague at the wrong time could lead you both to miss something important. And, of course, they may give you the wrong explanation!

96
Q

During a briefing, you think that the COSS has given the wrong information about the location you’re currently at, based on the Access Point Information Notice you can see. What would be your best response?

A

The best approach is to challenge during the safety briefing and then ask the COSS to compare their information with what you saw on the Access Point Information Notice.

You should always feel empowered to raise a concern with the COSS, so don’t ignore it or leave it to someone else.

97
Q

Prior to going on track, you overhear a colleague arguing on the phone with their partner and sounding stressed about bills. How would you best deal with this?

A

Talk to the COSS because the colleague will not be in a safe state of mind to be working on or near the line, and will likely become a danger to themselves or others. Don’t try and deal with the colleague’s problem yourself..

98
Q

While working alongside a colleague, you notice a strong smell of alcohol. You know that some of the team went out drinking last night. Which two of these would be the best courses of action?

A

Sharing your concerns with the COSS would be the responsible thing to do. A colleague with potentially impaired judgement due to alcohol in their system is a risk to both themselves and others. It would be even better if the colleague were to tell the COSS themselves.

99
Q

You fall on some sleepers while walking to site with your team and graze your knee. You are in some pain and discomfort and feel like you can’t carry on working. What should you do?

A

All accidents should be reported, however minor they are, as soon as possible – ideally within an hour.

If you don’t feel well enough to continue the work then you must stop working, come off track and get first aid so that the injury can be dealt with appropriately.

You should also raise a fault and a Close Call, so that actions can be put in place to mitigate dangerous underfoot conditions.

100
Q

What is a prohibition notice

A

A prohibition notice is one of the most important signs on the railway. If this sign is present it means there is no safe access to this part of the track while trains are running, except in an emergency or if a line has been blocked.

101
Q

Where might be considered a safe walking route?

A

Teams walking on or near the line must walk at least 2m (6ft 6in) from the track. This might be in the cess, or along an authorised walking route.

Where there is an authorised walking route, it must be used. Teams must be briefed on how to use it safely, including line speeds, direction of travel, identified hazards and any other safety related information.

102
Q

What sign does an emergency phone have and where are they located?

A

An emergency phone has a green sign. They are in places of safety and can be used to call the emergency services, the operator, or to report a fault.

103
Q

Q

How does a track circuit work?

A

The railway is divided up into different sections of track, each electrically isolated from the sections before and after it. Each section contains its own electrical circuit, which controls a signal located on the approach.

If there are no trains on that section of the track or on the one immediately ahead of it, the signal will be green, indicating to drivers that it’s safe to keep moving.

When the train enters a section of the track, it activates a circuit which changes the signal aspect to red. This tells the driver of the next train that there is already a train in this section, and they must wait.

As the first train moves along the next sections of the line, the signal changes back to yellow or green at which point the next train can enter safely.
