Pit permit Flashcards
(22 cards)
Correct Mayday procedure
- Mayday, mayday, mayday (wait for acknowledgement)
- Give your assets ID
- Give exact location
- Type of emergency
- Number of people injured (without giving names)
- Type of emergency services required
Isolate an LV during prestart
Ignition key removed and stored on person during the vehicle prestart
5 risks presented in the pits
- Dust
- Heavy machinery
- Blasting
- Slope failure
- Road conditions
Risks eliminated by being fundamentally stable
- Personal injury and machine damage
- Uncontrolled movement
Hierarchy right of way
- Emergency vehicles
- Autonomous trucks
- Working auxiliary equipment
- Left hand drive manually operated HME
- Non working auxiliary equipment
- MME/LME
How does a vehicle get fundamentally stable on a ramp?
- Turn wheels into a berm or windrow
- Position LV across ramp not facing up or down
- Wheel chocks
- Heavy vehicles require an earthen bund behind the downward side of the wheel
When are wheel chocks used?
In all circumstances where an LV cannot be parked in a fundamentally stable position
What is required from both operators prior to overtaking?
- Confirmation - through positive verbal communication
- Road is clear and free from obstacles
Can you pass any vehicles using hand signals?
No, you must use positive verbal communication
Maximum speed a vehicle can pass stationary equipment
25km/h
Hazards concerning passing stationary equipment
- Other road users
- Road conditions
- Visibility
- Dust
- Speed
- Proximity
When can LME do a u-turn on a haul road?
- Visibility is clear on roads
- Traffic is clear in all directions
- Minimum 100m from crest or intersection
- Turn in a single movement
LME to LME right of way
WA road rules
When can a LV park within 10m of HME
- Once the HME has been isolated by the driver
- For work purposes only
Onside of HME
- From the rear of the machine the onside is the left hand side
- For left hand vehicles it’s the side the cab is situated
- For centre drive HME it’s the side with the boarding ladder
Can LV approach an HME with the ladder in raised position?
No
Cones in the pit
- Yellow - Blast crew
- Blue - MEM
- Orange - General
- Green - geology/survey
Entering an demarcated by cones/ pyramids what are you required to do?
Stop and obtain permission via radios communication with the area owner
Radio channel is used for operations
- Para / ER - 40
- Channar - 50
- Plant - 45
- MEM - 41
- Emergency - 42
All intersections must be treated as LIVE. Why is this important?
You must never anticipate a HMEs direction, HME can change course with little to no indication. Slow down and asses every intersection and treat it as if there is a HME moving through the intersection.
The engagement process when entering a HME 50m exclusion zone:
Engagement within the 50m exclusion zone may take place provided:
1. LV makes positive radio communication outside the 50m exclusion zone
2. HME operator stops all operations
3. Parks in a fundamentally stable position
4. Grounds GET
5. HME operator exits cab
6. Operator lowers their boarding ladder
7. LV takes authority over the area
8. LV can approach and park on the on side, outside the HMEs 10m exclusion zone, avoiding blind spots and out of the line of fire
After the engagement
1. HME operator must remain outside of the cab and watch the LV leave the area
2. Operator can enter the cab
3. Once the LV is outside the 50m exclusion zone and provides all clear positive radio communication operations may resume
What is a cool zone?
A cool zone is a dedicated vehicle that can be left running with the air condition on to provide a cool location for personnel working in the heat
A cool zone can only be used where a dedicated crib hut cannot be accessed
a risk assessment is completed in a take 5
Vehicle is parked fundamentally stable, away from any interactions. Engine is turned off, wheel chocks put behind the wheels. Engine can be turned on and air condition left running
A cool zone sticker placed in the window to inform others why the car is running
