Intro to Material Handling Plan the task before

Intro to Material Handling

• Plan the task before doing it • Wear appropriate PPE • Follow lifting procedures • Pre-task planning • make sure the load is not too big, too heavy, or too hard to grasp • Watch for protruding nails, wires, or sharp edges

Figure 1 – Proper lifting procedures

• If you can not lift by yourself, get help • Inspect the path of travel – look for things that can make you slip, trip, or fall • Read warning labels – be aware of hazards • PPE • No loose clothing, tuck in and button shirts, remove jewelry, wear gloves whenever there are times you can get hurt

• Remove gloves when working with rotating equipment • Plan before lifting or lowering a load – find out how it got there, when it got there, and the size and weight of the load • Lifting - Firm footing, good grip, lift with legs, keep back straight, keep head up

• Keep aisles clear • keep away from the weather, follow carton guidelines • stack pipes so that they will not roll, tie down if possible • store flammables away from things that will ignite • When stacking bags that are the same width, step back and cross the bags every 10 bags high • Don’t store materials on scaffolds

Material handling equipment • Non-motorized • Material cart – platform truck – platform with casters – transport materials around a jobsite – make sure you do not exceed the weight • Hand truck – dollies, two – wheeled carts used to transport heavy loads • Cylinder carts – used to carry gas cylinders • Wheelbarrow – one or two wheeled vehicle with handles at the rear

• pipe mule – two-wheeled device used to carry medium length pieces of pipe, tubing, or scaffolding • Pallet jack – typically uses hydraulics to lift and move heavy or stacked pallets • A roller skid may have a rotating table surface or spikes on the table

• Motorized – be trained, certified, authorized • Powered wheelbarrow – power buggy – like a manual wheelbarrow, but with a motor • Concrete mule – Georgia buggy – moves concrete, sand, gravel • Freight elevator – most of them close from top to bottom – heavy duty

• Industrial forklift – power operated – lift, lower, transport large equipment – usually used on flat, solid ground • Rough terrain forklift – used on irregular surfaces – not paved • Fall zone – any area where lifted material can fall – keep the load low

Knots • Square knot – used to tie the ends of a rope around an object –commonly used to join two lengths of rope together in low-strain applications –same size rope

• Bowline knot – used to form a secure loop in the end of a rope – does not slip or bind when under a load

• Half-hitch – ties a rope around an object like a nail, bar, post, or ring – commonly used for tasks like suspending items from overhead beams – stable knot but not for heavy loads

• Clove hitch – one of the most widely used hitches – quick and secure tension knot on a fixed object that serves as an anchor – comes loose as soon as tension is removed – can bind – can use two half hitches to tie

FORKLIFT HAND SIGNALS • Raise the tines – forearm vertical, forefinger pointing up, move hand in small horizontal circle • Lower the tines – arm extended, palm down, lower arm vertically • Tilt mast back – forearm vertical, thumb extended, jerk thumb over shoulder

• Tilt mast forward –arm extended, fingers closed, thumb pointing downward, lower arm vertically • Move tines in direction finger points – arm extended, palm down, point forefinger in direction of movement • Dog (pause) everything – clasp hands in front of body

• Stop – extend both arms, palms down • When using hand signals maintain eye contact with the operator
