10
Lift Truck Hazards n Collision with people or vulnerable plant n Overturning n Items falling from racking or forks n Explosion from some batteries n Hot exhaust n Dangerous parts e.g. chains, drive shafts etc. n Driving off edges, into pits etc. n Placing loads onto peoples feet
11
Lift Truck Hazards n Fumes n Noise n Whole body vibration n Load slipping from forks
12
Lift Truck Control Measures
13
Driver Selection n Reliable and mature attitude n Physically & mentally fit n Intelligent n Over school leaving age n Not under influence of drink/drugs n Good vision n Good hearing
14
Driver Training n Supervisors should receive an appreciation n Competent Instructor n Records should be kept n Test at end of training n Employees should be given written authorisation at end of training n Refresher training as necessary
15
Work Area n Separate traffic routes where possible n Routes should have sufficient width and clearance for largest trucks used n Prevent pedestrians entering lift truck areas n Eliminate sharp bends or overhead obstructions wherever possible n Where hazards cannot be removed, use clearly marked barriers
16
Work Area n Signs, warning devices, mirrors etc. n Instructions to sound horns and restrict speed n Flexible doors of transparent material where lift trucks have to pass through
17
Work Area n Edges of loading bays, excavations & pits should be clearly marked
18
Work Area n Where possible, edges should be fitted with barriers
19
Work Area n Operating areas should be as free as possible of obstructions, but supports, columns, pipework, racking or other plant may need to be protected by special impact barriers
20
Work Area n Firm and level surface, ideally concrete or similar n Potholes should not be allowed to develop n Steep gradients should be avoided n Adequate lighting n Trucks should be parked in a secure area n Keys should be kept in a secure place
21
Protecting Pedestrians & Operators n Segregate pedestrians and vehicles
22
Protecting Pedestrians & Operators n Clearly mark traffic routes n Use audible and visual warning devices n High-visibility clothing may be necessary, as well as safety boots and hard hats n A Roll Over Protection Structure should be fitted where there is a risk of overturning and crushing operator
23
Protecting Pedestrians & Operators n Seat belts may be required n Falling object protection structures should be fitted where there is significant risk of falling materials n Anyone driving a lift truck on a public road should comply with road traffic legislation
24
The Lift Truck n Suitable for its intended purpose n Travel with loads in lowered position n Do not load beyond SWL (safe working load) n Dangerous parts should be guarded n Eliminate ignition sources in battery charging areas n Adequate ventilation to disperse fumes
25
Operation of Lift Trucks n Issue keys only to authorised people n Lower forks when parked n Keep to left when operating n Sound horn at danger spots n Avoid violent braking or sudden changes in direction n Never travel down slopes with load in front
26
Maintenance n Follow manufacturers recommendations n Operators should not carry out repairs n Trucks that are on loan still need to be checked and maintained
27
Operator Checks n At beginning of each shift, operator should check the following and report any defects to his supervisor: –Tyre pressure and damage; –Steering and brakes; –Fuel, water and oil levels; –Battery levels; –Masts and hydraulics; –All controls; –Horns and other warning systems; and –Lights & mirrors
28
Conveyor Belts
29
Conveyor Hazards n In-running nips n Entanglement points at rollers n Contact with moving parts n Materials falling from conveyor n Manual Handling/Ergonomics from incorrectly set speeds
30
Conveyor Controls n Guard in-running nips
31
Conveyor Controls n Emergency trip wires or stop buttons n Guard power drives and other dangerous parts n Nobody allowed to ride on conveyor n Operatives should be trained and instructed in safe use
32
Conveyor Controls
33
Automated Warehouses & Order Picking Machines (OPMs)
34
OPM Hazards n Overturning e.g. overloading, gradients n Falls of people, goods or materials n Trapping of people in mechanisms n Trapping of people against fixed structures n People struck by moving OPM n Failure of platform supporting mechanism n People stranded on platform due to power failure n Inadvertent movements e.g. misapplication of controls
35
OPM Controls n Only trained and authorised persons n Comply with SWL n Tested and examined every 6 months (LOLER) n Prevent access to dangerous parts e.g. chains, mast sections etc. n Edge protection n Suitable overhead guards
36
Automated Warehouse Hazards n Collision between AGVs and people n Trapping points between AGVs and stationary objects or fixed structures n Inadvertent movement of AGVs n Collapse of palletised loads n Collapse of AGV n Slips on oil from machines
37
Automated Warehouse Controls n Segregate AGVs from pedestrians n Trip devices on vehicle bumpers n Sensors on vehicles to slow it to a crawl n Ensure accurate positioning of AGV at transfer points n Easily accessible emergency stops n Automatic monitoring of safety system
38
Automated Warehouse Controls n Audible and visual signals n Guard dangerous moving parts n Prevent unauthorised human access n Pressure sensitive mats n Interlocked access gates n Permit systems for maintenance n Clear warning notices
