oreder to avoid any injuires. 5.Clear the loading area,PPE. 6.Boom swing area to be barricaded:unauthorized
personnel not to be allowed. 7.Loose materials shall not be lifted other than in material basket.clear the loading area. 8.Rigging and rigginpg plans checked by competent person prior to use ans ensure the lifting area is free from those hazards.
1.3 Slipping, Tripping and Falling
1. uneven or slippery work surfaces 2. poor housekeeping, e.g.. Swarf in the vicinity of the equipment, spillage not cleaned up 3. lack of a proper work platform 4. lack of guardrails or
suitable edge protection 5. unprotected holes,
penetrations or gaps 6. poor floor or walking
surfaces, such as the lack of a slip resistant surface 7.steep walking surfaces 8.collapse of the supporting structure
1. Slippery due to cleaning of the floor 2. Slips and Trips due the improper cable management & other obstacle 3.Path way not clear 4.Slips, trips and falls due to poor housekeeping.
Personal Injury / Property damage
2 3 6 1. Proper housekeeping
2. Proper signs at needed
location e.g. "Slippery Surface" 3. Keeping walkway clear of
waste, sharp edges etc. 4. Access ways/walk ways to be kept clear and free of
obstructions. 5.Good housekeeping practices need to be maintained
L Minimize the risk using control measures
1. is too strenuous, e.g. it is carried out too frequently or for too long a time; 2. involves awkward postures or movements, e.g. a bent and/or twisted trunk, raised arms, bent wrists, over- reaching; 3. involves repetitive handling. slippery materials/objects handled. lifting materials 3. Twisting 4. Object falling from height 5. Improper usage of lifting
equipment 6. Slipping materials from
hands and resulting crushing injuries.
pain 2. Use proper lifting equipment
3. Manual handling training provided. 4. Use proper hand gloves when required while handling materials.
