In recent times, Many accidents are happened while hoisting materials at construction sites in India.
On day to day basis workers are prone to such incidents at job sites.
What is Hoist ???
Hoists are generally used on construction sites to transfer goods and/or materials between the ground and elevated floors of a multi-level structure. A hoist system comprises a car, mast tower, mast ties, base / landing systems and a drive unit.
Different Types of Hoists:
Material hoist
Passenger hoist
Boom hoist
Platform hoist
Bucket hoist etc.,
Operating hoists can present a risk of injury to people from the following:
Hoist collapse: This can occur due to the failure of the mast structure or if the hoist is not adequately secured to the supporting structure. A collapse may be influenced by several factors, including overloading or incorrect installation of the mast structure or supporting ties.
Contact or collision with other structures: This can occur when sufficient clearances are not maintained between where the hoist car will travel and other structures, such as cranes, EWPs, concrete pumping booms, buildings and overhead power lines.
Contact with moving parts: This can occur where any part of a person’s body is able to access moving parts of a hoist system, including at the base and at all landing areas.
Falling objects: This can occur from hoist components or any part of a load falling during erecting, jumping and dismantling activities, when entering or leaving the hoist car from a landing, or during raising or lowering.
Fall of person from height: This can occur during activities associated with shifting of materials from the unsecured landing area.
Things to remember:
• In construction site, use the hoists to shift only the materials if required & permitted.
• Personnel movement / travel in the material hoist or any type of hoist used at construction sites must be restricted to prevent any untoward incidents which could results in serious injuries or fatality.
• Use only the stair case to reach the desired work locations and shift the materials accordingly.
• Load the materials in the hoist with in the specified rated load & secure the load properly.
• Ensure no movement of personnel under the hoist.
