SAFETY SERIES:– 16 | SCAFFOLDS AND WORKING PLATFORMS

SAFETY SERIES:- 16
 
SCAFFOLDS AND WORKING PLATFORMS
 
I. SCAFFOLDS

Safety Videos




Scaffolds should be erected as per required standard.



 INSTRUCTIONS FOR SCAFFOLDS
  1. Scaffolding should be strong, sturdy and sway free.
  2. Scaffolds should preferably be of metal tubes with bolted joints or made of wooden (casurina) poles and tied with wet coir. Bamboos shall not be used for scaffolding.
  3. Erection of scaffolding should be from lift pit bottom to the bottom of machine room.
  4. Wooden poles used shall be of sound material and free from any defects like cracks, termites etc.,
  5. The diameter of vertical casurina poles should be 4” (100 mm) and that of horizontal 3” (75 mm) minimum.
  6. The horizontal members must be tied at a vertical spacing of 750 mm. (2 ½feet)
  7. For rigid scaffolding, horizontals should be stuck against side walls.
  8. The coir ropes used for tying wooden poles should not be worn. The coir ropes should be wetted periodically.

DAILY CHECKS


  1. Check the tying of scaffolds before entering the scaffold.
  2. Check whether Scaffold shakes before entering the scaffold.
  3. Check whether the wooden poles are firmly rested and are not shaking before stepping on them.

II. WORKING PLATFORMS
 

SPECIFICATION

  1. The working platform should be more than 650 mm wide.
  2. For 1 m support span, Board thickness should be more than 32 mm.
  3. For 1.5 m support span, Board thickness should be more than 38 mm.
  4. 50 mm thickness board can be used for support span of 2.6 m.

DAILY CHECKS

  1. Check whether wooden planks are as per standard Specification.
  2. Check whether wooden planks are free from cracks and any other defects.
  3. Check whether wooden planks are tied firmly to wooden poles before stepping on it.

SAFETY SEEDS : SAFETY AND SCAFFOLDS



TOPICS : SAFETY AND SCAFFOLDS

 

It is safe to assume that just about everybody has heard of a scaffolding accident or two.

In many of those cases, faulty design and inadequate construction of the scaffolding was involved but, in most case, scaffold accidents are caused by poor maintenance and improper use.


  

To help keep your scaffolds safe, follow these simple procedures:


  1. Ensure that the scaffold is built as per safety standards.
  2. Inspect the scaffolds daily before using them; Check the guard rails, connectors,fastening, footing, tie-ins and bracing.
  3. Ensure ladders are intact and secured.
  4. Check for inspection tags ( Green or Red ) before using scaffold. Use them only if tagged green. Red or no tag means the scaffold is unsafe.
  5. Keep platforms closely boarded, fenced and securely fastened.
  6. Don’t stockpile materials on the scaffolds: remove all materials and tools at the end of the day.
  7. Never overload scaffolds. Place the materials being used over ledger and bearer points to minimize platform loading.
  8. Don’t work on scaffolds during storms or high winds.
  9. Protect the scaffolds; don’t bump or strike against the scaffolds with vehicles or materials and control hoisted material from the ground with taglines.
  10. Keep the platforms and area around the scaffold cleared of debris and unneeded equipment, material and other hazards that will cause a worker to trip or fall.
  11. Use safety belts, and tie it off if you are working above 10 feet.

Safety Tips: Working at Height

Safety Tips: Working at Height

Working at height remains one of the biggest causes of fatalities and major injuries. Common cases include falls from ladders and through fragile roofs.
Work at height means work in any place, including at or below ground level (for example in underground workings), where a person could fall a distance liable to cause injury.
This section shows how employers can take simple, practical measures to reduce the risk of any of their workers falling while working at height.


Case study

Trained workers now wear a fall-arrest harness that can be attached to the line and the ladder. This means that the ladder cannot slip during use and, even if the engineer slips and falls from the ladder, What do I have to do?

You must make sure that all work at height is properly planned, supervised and carried out by people who are competent (someone who has the skills, knowledge and experience) to do the job. This must include the use of the right type of access equipment. 


To prevent or minimize risk when planning for work at height, consider what needs to be done and take a sensible, risk-based approach to identify suitable precautions.


Control measures
There is a simple hierarchy of control measures (as described below) which you should follow to minimize the risk of a fall from height. The hierarchy should be followed systematically and only when one level is not reasonably practicable. This means balancing the level of risk against the measures needed to control the risk in terms of money, time or trouble. The decision is weighted in favor of health and safety so that the measures are adopted unless they are grossly disproportionate may the next level be considered.
Those in control of the work need to:
· Avoid work at height where they can
· Use work equipment to prevent falls where work at height cannot be avoided
· Where the risk of a fall cannot be eliminated, use work equipment to minimize the distance and consequences of a fall if one occurs
· Always consider measures that protect all those at risk, i.e. collective protection measures (scaffolds, nets, soft landing systems) before measures that only protect the individual, i.e. personal protection measures(a harness)

Dos and don’t of working at height
Do….
· Make sure the surface/access equipment in use is stable and strong enough to support the worker’s weight and that of any equipment. Any edge protection should be wide enough and strong enough to prevent a fal

· As much work as possible from the ground or partly from the ground, for example assemble structures on the ground and lift them into position with lifting equipment

· Take precautions when working on or near fragile surfaces, e.g. an asbestos cement roof, to prevent a fall or to minimize the distance and consequences in the event of a fall

· Ensure workers can get safely to and from where they want to work at height and also consider emergency evacuation and rescue procedures

· Make sure everyone involved is competent to do the work they are responsible for, including those who plan and organize it

· Choose the most appropriate equipment for the type of work being done and how often it will be used

· Provide protection from falling objects

· Make sure equipment used for work at height is well maintained and inspected regularly


Don’t…
  • Overload ladders – the person and anything they are taking up should not exceed the highest load stated on the ladder
  • Overreach on ladders or stepladders – keep your belt buckle (navel) inside the stiles and both feet on the same rung throughout the task
  • Use ladders or stepladders if the nature of the work is deemed to be ‘heavy’ or if the task will take longer than thirty minutes or so to complete
  • Use ladders if workers cannot maintain three points of contact (hands and feet) at the working position. If this is not possible, consider an alternative safe system of work
  • Let anyone who is not competent (someone who doesn’t have the skills, knowledge and experience to do the job) carry out work at height
