GC2 Flashcards
Revise
Identify the possible effects on health from working in a hot environment
Dehydration, fatigue, muscle cramps, heat stress, heat stroke, burns
Outline control measures for work in a hot environment
Eliminate the need to work in a hot environment - if this is not possible then reduce the heat by providing work place ventilation (LEV, ceiling extractor, natural ventilation)
Insulate the sourced of heat, eg lagging hot pipes, to reduce the additional heat being introduced into the area and the direct source of heat which may cause burns.
Shield heat courses eg control radiant heat and prevent contact burns, cooler material can be used to guard source eg heat proof plates
Provide cool refuges for the workers to be comfortable and recover during breaks.
Provide easy access to plenty of drinking water.
Frequent breaks and job rotation.
Provide appropriate clothing for the work site which will protect against all the other work place hazards but not add to the overheating of the employee.
Outline measures to minimise the risk of violence towards employees (8)
Central office:
Zero tolerance and prosecute offenders - posters on the wall
Security doors and screens - keep staff and public separate (eg bank teller being class screen)
Reduce stress and minimise violence potential by managing the public well, having good processes, good communication.
Panic alarms for those at risk and training on how to use them.
Home visit - community nurse
Remove or reduce lone working, particularly with high risk visits.
Supervisor to have plan of visits and times. Check in with supervisors at given times or make pre and post visit calls (use technology)
Training in self defense for those at risk - as last resort in case they need to create an opportunity to get out of tricky situation.
Advise not to carry electronics, valuables etc which may increase chance of robbery in low income areas.
Use technology - apps which track location and can initiate alarms if required.
Identify the hazards which may cause slips and trips at work
Slips - wet or oily surfaces.
Slips - Cold temperatures
Trips - Uneven surfaces
Trips - Equipment left lying around
Open excavations
Identify how slips and trips in the work place may be controlled.
Spills should be cleaned up immediately and signs posted.
If cold weather is forecast then the walkways and roads should be gritted and salted to prevent freezing.
Safety tours should take place focusing on walkways and looking for uneven surfaces, routine inspections by HSE department could take place.
Safe system of work/ controls when creating open excavations or removing manhole covers. Barriers in place and standby man.
Good safety culture and interventions if equipment is left lying about , creating a hazard.
Outline precautions to be taken when carrying out repair on a sloping roof
Safe means of access and egress - either a scaffold or ladder.
Safe work site - either handrails or harness and fall arrestor should be used.
Use a MEWP if possible to remove the need to access the roof
Appropriately trained work force, aware of the hazards and how to control them.
Install collection measures to minimise the impact if there is a fall - safety nets
If a scaffold is used, ensure toe boards and handrails are used to prevent either objects or people from falling overboard.
Erect a covered walkway below the work site to protect the public from dropped objects
Total exclusion zone may be required below the work site depending on the area and amount of risk.
Use pulley system to transport materials to the work site safely
Install a rubbish chute to ensure waste is transported to skips safely and does not create a dropped object hazard
If visual inspection consider using a drone survey to avoid any working at height risk or to assess the area and improve risk assessment.
Mobile tower scaffolds should be used on stable ground.
Identify additional factors which should be considered for the safe use of a mobile tower scaffold.
Outriggers
Level ground
site checks
brakes on wheels
guard rails
pre-use checks
barriers or exclusion zones
brick guards or toe boards - dropped objects
cross bars to prevent tilting
traffic management
lanyards
maintenance routine - scaffold inspection
SSOW
training & PPE
Identify the precautions which should be in place during the use of step ladders
Work on solid dry ground
Correct footing
regular and pre-use inspection
Choose correct size
3 points of contact or use a harness
don’t overreach
don’t overload
tie off tools to prevent drops
use barriers
Non slip footwear
training in inspection and use
PtW system/ SSOW
eliminate use if possible
Identify the main hazards that may be present during demolition of a building
Unscheduled collapse of the structure
Falling or flying material
Working at height
contact with overhead services or wires
contact with underground services or cables
dust
asbestos
Sewage/ biological hazards
lifting operations
explosion
noise
vibration
entrapment
Identify the main hazards which may be present during excavation work on a construction site.
Confined space working
underground services
collapse of sides
fall from height into the excavation
falling materials, dropped objects
unsafe or unstable ground
public or traffic nearby
slips trips and falls
spills or contamination coming into the hole.
Heavy machinery collapsing excavation
weakening adjacent foundations
Outline control measures that could be implemented to reduce risks to pedestrians in a warehouse
Speed limits/ limiters on forklift trucks
Pedestrian walkways - painted different colours
Raised walkways or hard barriers to create a physical barrier to protect pedestrians
Ensure all forklifts are fitted with visual and audible warning beacons (lights and horn)
Use a banksman for reversing large vehicles
Designated loading and unloading points
Pedestrian no go zones for particular high risk times
High visibility clothing to ensure everyone sees each other
Mirrors at corners to provide warning of what is coming.
Identify physical features of traffic routes within a work place which are required for the safe movement of vehicles and safety of employees
Barriers
Bumper bars
raised walkways
raised work platforms
cages on hazardous equipment
speed bumps
road markings
hazard tape during loading or unloading etc
reversing areas
traffic lights
alarms on vehicles
alarms when areas are in use
alarm when accessing restricted area
Outline factors to consider when completing a display screen equipment workstation assessment
Adjustable height, angle back support to prevent musculoskeletal or upper limb disorders caused by poor ergonomics
Correct seat adjustments to ensure that the hands sit comfortably on the keyboard. Seat should have 5 star base for ease of rotation and movement
Lost of space under the desk, no clutter or obstructions which will affect seating position.
Workstation should be uncluttered, spacious with ease of access to all equipment without the need to stretch.
Adjustable tilt and height on the screen, no flickering, no glare, clear contrast, good size and clean.
Space in front of the keyboard to rest the wrists, space for document holder if required.
Minimise eye strain by allowing regular breaks from DSE and checking condition of equipment.
Identify specific types of injury which could be caused by manual handling
Back injury
Tendon and ligament injuries
Muscle Injuries
Hernias
Work related upper limb disorder
Cuts, burns, dislocations, broken bones
Outline factors to consider in relation to the load which will affect risk during manual handling
The weight of the load.
The size of the load - is it big and bulky - sight restriction, getting a grip.
The stability of the load, is it liquid inside, is the centre of gravity moving, stress on the body will not be constant.
The shape of the load may not allow for a good stable grip, particularly if not using correct gloves.
The load may be hot, sharp, hazardous, chemicals etc.
Identify 8 ways a forklift truck may become unstable during operation
Wet or slippy surface
Unseen hole in the ground, uneven surface
Unstable ground - not fit to take the weight of a forklift.
Accelerating or braking too quickly
Turning to sharply
Driving with elevated load
Carrying a load too heavy
Carrying an unstable load.
Driving across a slope
Driving up or down a slope
Collision with overhead cables or obstructions
Describe the principles of a trip device
A trip device is a sensitive piece of equipment that will stop the machine from working. For example a motion sensor or proximity sensor, light beam, will cut power to a production line if anyone in certain areas. Pressure mat, trip bar etc.
Describe the principles of 2 hand controls
Does what is says on the tin - both hands are required to push buttons to supply power to the machine. by doing this it prevents the user from having a free hand to put in the hazardous location.
Describe the principles of an interlock guard
An interlock guard is a guard which needs to be removed as part of routine operation or maintenance. When the guard is removed a switch is opened which prevents power being supplied to the machine, so allows safe access to the hazardous parts. Wont run until guard is replaced (eg microwave door)
Describe the principles of protective appliances
Devices an operator can use to assist in safe operation of a machine. eg a push stick for cutting wood to prevent the need tp put hands in dangerous area
Petrol cylinder mower to be used.
Outline mechanical and non-mechanical hazards associated with its use
Mechanical Hazards:
Rotating sharp blades present a cut hazard
Entanglement hazard - loose items may get caught in moving parts
Drawing in hazard - rotating blade
Collision/ crushing
