Storage and Handling of specific materials

What is the Storage and Handling of specific materials?

Storage and Handling of Bagged Materials:

Cross ties with mouths inside. When pile is five high, step back by one row for each additional three feet. Do not remove a bag from a lower row first.

Storage and Handling of Bagged Materials

Storage and Handling of Pipe and Bar Stock:

Consider strength of floor. Pipe in layers which strips of wood or iron between layers. Strips should have block at one end or one end turned up. Bar steel stock would be stored in racks, inclining towards the back. Barrels and Kegs: Pyramid shape is safer. Bottom row should be blocked. If piled on ends, planks should be laid between rows.

Liquid Chemicals:

Portable containers such as drums, barrels and carboys should be stored and handled carefully. Store room should have impervious walls and floors and provision for safe disposal of spillage.

Storage and Handling of Liquid Chemicals

Before handling, check corrosion of nails or weakening of packing by the chemical. For transporting carboys use a carboy trolley. Safe way to empty a carboy is to move liquid by suction from vacuum pump or start the siphon by means of rubber bulb. Properly designed carboy inclinations are also satisfactory. Before piling Empty carboys should be thoroughly drained and stoppers replaced.

Storage and Handling of Gas Cylinders:

  • Cylinders may be rolled on the bottom edge but never dragged.
  • Carry cylinder in a cradle or in a suitable type of carrying device.
  • Do not permit them to strike each other violently.
  • While returning empty cylinders or when not in use, close the valve.
  • Replace valve protection cap.
  • Always consider cylinders as full and handle them with care, Do not store as cylinders in the sun or excess heat.
  • Follow the Gas Cylinder Rules 1981 and JS:5903.

Storage and Handling of Dangerous Substances Chemicals:

  • Dangerous substances should handled and stored under the supervision of a competent person who is familiar with the risks and the precautions to taken.
  • In case of doubt as to the nature of the risk of the precautions to be taken, the necessary instructions should be obtained from the competent authority.
  • When dangerous substances are to be handled or stored, the workers concerned should be given adequate information concerning their nature and the special precautions to be observed in handling them.
  • Special precautions, such as the provision of mats, sling nets, boxes and high sided pallets, should taken to prevent breakage of or damage to containers of dangerous substances.
  • If containers of dangerous substances broken or damaged to a dangerous extent work should stopped and the workers concerned removed to a safe place until the danger has been eliminated.
  • When highly flammable material is handled, special measures should taken to ensure that an incipient fire can controlled immediately.
  • When necessary, non-sparking tools should be provided and used in explosive atmosphere.
  • Where corrosive substances are handled or stored, special precautions should be taken to prevent damage to the containers and to render any spillage harmless.
  • Workers handling harmful substances should thoroughly wash their hands and face with soap and water before taking any food or drink.

Floors:

Depending upon the type of operations, the conditions of the floor such as:

  • Cleanliness
  • Marking
  • Absorptive qualities.
  • Non-sparking of static disseminating properties
  • Durability will give great effect on material handling.
  • Color

What are the Body Postures While Manual Material Handling?

Correct positioning of feet:

Working with legs too close to each other results in loss of balance of the body. While lifting a load, space the legs apart by hip width with one foot by the side of the load and ahead of the other foot in the direction of movement

Knees Bent:

Keeping legs straight and bending forward to lift a load is dangerous. This position has risk of loss of balance, cramping of lungs and consequent breathing difficulty. and straining the spine. For a strong and powerful position, bend knees and not the back to reach the load.

Body Postures While Manual Material Handling

Straight back:

A straight back need not necessarily mean a vertical back. In most lifting posture, the back needs to inclined from hips, but at the same time keep it straight.

Arms close to the Body:

The farther the load is to the body, the greater is the strain.

Correct grip:

Do not try to lift with fingertips. Grasp the load using palm and roots of the finger.

Head in correct position:

Before lifting raise the head slightly This also helps keep back straight.

Use of Body weight:

By positioning the body such that its weight counter balances the load to lifted, possible to obtain not only balance but greater mechanical advantage than what can obtained through bending the back forward.
