how to prepare lifting plan and load calculation

Lifting Plan and Load Calculation  

When planning a lift, safety and precision are key. Here’s a straightforward breakdown of how to approach it:

1. Understand the Load 

Weight: Confirm the exact weight of the object (check manufacturer specs, weigh it, or calculate based on material density).

Dimensions: Note the size, shape, and center of gravity—bulky or uneven loads require special rigging.

- **Attachment Points**: Identify secure lifting points to avoid imbalance or damage.  

2. Choose the Right Equipment

Crane/Lifting Device: Ensure its capacity exceeds the load weight (factor in a safety margin, usually 25-30% above the load).

Slings/Chains/Rigging: Check their Working Load Limit (WLL) and ensure they’re rated for the load.

Hardware: Shackles, hooks, and spreader bars must also meet weight requirements.

3. Calculate Total Load

Include:

Primary Load: Weight of the object.

Rigging Weight: Slings, hooks, and attachments add extra load.

Dynamic Factors: Wind, movement, or acceleration can increase force (use multipliers like 1.5–2x for safety).

Example Calculation:

- Object weight: 10,000 kg  

- Rigging weight: 500 kg 

- Dynamic factor (1.5x): (10,000 + 500) × 1.5 = 15,750 kg total load 

- Crane capacity needed: 20-ton crane (to stay within safe limits).

4. Verify Ground Conditions

- Ensure the ground can support the crane/equipment (check for stability, mats, or outriggers if needed).  

5. Plan the Lift

- Path: Clear obstacles and ensure no power lines/structures interfere.  

- Communication: Use spotters and hand signals/radios.  

- Contingencies: Have a plan for emergencies (e.g., load stuck, sudden weather changes).  

6. Document & Brief the Team

- Write a formal lifting plan (including weights, equipment, roles, and risks).

- Conduct a toolbox talk to review steps with all workers.

Final Tip: When in doubt, overestimate loads and underspeed lifts—better safe than sorry.  

Essential Ladder Safety Guide

Essential Ladder Safety Guide

ABU DHABI 

Ladders are one of the most commonly used tools at home and on worksites. Whether it's changing a light bulb, cleaning gutters, painting walls, or reaching high shelves, ladders make everyday tasks easier. However, their frequent use often leads to overlooked safety practices, increasing the risk of falls and injuries

The Often-Overlooked Danger of Ladders on Construction SitesLadders are a common sight on construction sites, used daily for quick access to elevated areas. Their simplicity and convenience often lead workers to underestimate the risks involved. However, improper use, damaged equipment, or lack of proper training can turn this everyday tool into a serious safety hazard. Falls from ladders remain one of the leading causes of injuries and fatalities in the construction industry, highlighting the urgent need for proper ladder safety awareness and protoco

Purpose of the Post:The purpose of this post is to raise awareness about the often-overlooked dangers of ladder use on construction sites. It aims to educate workers and supervisors on the importance of proper ladder selection, inspection, and safe usage practices to prevent accidents, injuries, and fatalities. By highlighting common hazards and promoting safety measures, this post encourages a proactive approach to ladder safety in the workplace

1. Choosing the Right LadderSelecting the correct ladder for the task is the first step to ensuring safety. Consider the height needed, the type of work, and the ladder’s weight capacity. Using a ladder that’s too short, too tall, or not designed for the job can lead to instability and increase the risk of falls. Always check if the ladder is rated for industrial or construction use, and never substitute with makeshift alternatives.

Types of Ladders Commonly Used on Construction Sites:

1. Step Ladder
   A self-supporting, foldable ladder ideal for tasks that don’t require leaning against a wall. Suitable for indoor and light-duty work.

2. Extension Ladder
   A non-self-supporting ladder that can be extended to reach higher areas. Commonly used for exterior work like roofing or facade maintenance.

3. Platform Ladder
   Similar to a step ladder but with a platform at the top for better balance and comfort during prolonged tasks.

4. Multi-Position Ladder
   A versatile ladder that can be configured into various shapes—step, extension, or scaffold—depending on the task.

5. Trestle Ladder
   Often used in pairs with a plank for scaffolding setups. Ideal for working at height over longer spans.

6. Fixed Ladder
   Permanently attached to structures like tanks or towers, offering regular access to specific elevated areas.

Each type serves a different purpose—choosing the right one reduces risks and improves efficiency.

Material:

• Fiberglass: Best for electrical work (non-conductive).

• Aluminum: Lightweight, durable, but conductive (avoid near electricity).

• Wood: Traditional, non-conductive, but can rot/splinter.

Duty Rating (Weight Capacity): Explain why checking the duty rating is critical (e.g., Type III, II, I, IA, IAA). It includes user weight plus tools and materials. Always check the label!

Height: Ensure the ladder is tall enough for the job without overreaching, but not excessively tall where it's unstable.

2. Pre-Use Inspection: Your First Line of Defense 

• Visual Check: Before every use, quickly inspect the ladder.

• Rungs/Steps: Look for cracks, bends, loose connections, or damage.

• Side Rails: Check for dents, splinters, cracks.

• Feet/Pads: Ensure they are present, intact, and not worn or slippery.

• Spreaders/Locks (for step ladders): Must be fully extended and locked.

• Ropes/Pulleys (for extension ladders): Check condition and function.

• Labels: Are safety labels legible?

• NEVER use a damaged ladder. Tag it for repair or discard it

• 
  

• 3 .Setting Up Safely  Stable Surface:Always place the ladder on a firm, level, non-slippery surface.Avoid soft ground (mud, loose gravel) or uneven surfaces.Use ladder leveling devices if necessary.Clear the Area: Remove any clutter, tools, or tripping hazards around the base and top of the ladder.

• • Extension Ladders - The 4:1 Rule:

    • For every four feet of ladder height, the base should be one foot away from the wall. (e.g., if the ladder extends 16 ft up, the base should be 4 ft from the wall).

    • Use the "toe-to-base" test: Stand with your toes at the ladder's feet; your outstretched arms should touch the rung at shoulder height.

  • Extension Ladders - Overhang: The top of the ladder should extend at least 3 feet (about 3 rungs) above the landing surface to provide a handhold.

  • Secure the Top (if possible): If the ladder might slip, tie it off at the top to a secure anchor point.

  • Locking Mechanisms: Ensure all extension locks and spreader bars are fully engaged and secure.

  4. Climbing and Working Safely (Approx. 250-300 words)

  • The Three-Point Contact Rule: Maintain three points of contact with the ladder at all times (two hands and one foot, or two feet and one hand).

  • Face the Ladder: Always face the ladder when climbing up or down.

  • Center Yourself: Keep your body centered between the side rails. Never overreach! If you can't reach, descend and move the ladder.

  • Tools & Materials: Use a tool belt or hoist tools/materials up separately. Do not carry items that prevent three-point contact.

  • Footwear: Wear clean, dry, non-slip footwear.

  • Don't Stand on the Top Rung/Platform:

    • On a stepladder: Never stand on the top cap or the step below it unless specifically designed for standing.

    • On an extension ladder: Never stand on the top three rungs.

  • Avoid Overreaching: The most common cause of falls. If you can't comfortably reach, get down and reposition the ladder.

  • No "Walking" the Ladder: Never try to slide or "walk" a ladder while standing on it.

  • Weather Conditions: Avoid using ladders in high winds, rain, or icy conditions.

  • Electrical Hazards: Always be aware of overhead power lines. Maintain a minimum of 10 feet clearance from power lines. Use fiberglass ladders if working near electricity.

  • One Person Per Ladder: Unless it's a specially designed twin-stepladder, only one person should be on a ladder at a time.

construction of fire extinguisher

The Construction and Operation of Modern Fire Extinguishers

Modern portable fire extinguishers are typically Stored Pressure or Cartidge Operated Fire Extinguishers. Manufacturers of fire extinguishers tend to produce both types of fire extinguisher with stored pressure fire extinguishers being the most common.Fire Extinguisher Construction Materials.

Typically modern fire extinguisher bodies are constructed from Steel, Aluminium or Aluminium Alloy. These materials give the fire extinguisher a durable exterior to withstand knocks, external temperatures and corrosion. The cartridge in gas catridge operated fire extinguishers is usually coated in plastic to give the catridge extra protection against the contents of the fire extinguisher. There are two types are gas cartridges in modern fire extinguishers, these are; piercing disc and frangible pip cartridges. The piercing disc gas cartridge features a diaphragm which is pierced by a suitable shaped spindle. The frangible pip gas cartridge features a pip which is broken by a blunt spindle. In a gas cartridge operated fire extinguisher only the cartridge itself is pressurised whereas in a stored pressure fire extinguisher the entire body of the fire extinguisher is pressurised

How the different fire extinguishers work.

Stored pressure fire extinguishers work in the following way:-

 1. The fire extinguisher is operated by releasing the pin, breaking the tamper seal and pressing down on the fire extinguisher handle.

 2. The pressure stored within the top of the fire extinguisher (dry air or nitrogen) is released.

 3. The pressure forces down on the extinguishing agent within the fire extinguisher (water, foam, powder etc.)

 4.The extinguishing agent is forced up the syphon tube within the fire extinguisher, through the head cap and hose onto the fire.

 5.Some fire extinguisher hoses are fitted with a squeeze grip control to regulate the flow of the extinguishant. 

 

 Gas cartridge fire extinguishers work in the following way:-

 1. The fire extinguisher is operated by releasing the pin, breaking the tamper seal and pressing down on the fire extinguisher handle.

 2. The action of pressing down on the fire extinguisher handle pushes a pin down onto the seal of the gas cartridge.

 3.The pin pierces the seal on the gas cartridge and releases the pressure in the gas cartridge.

 4.The pressure within the fire extinguisher from the gas cartridge then forces down on the extinguishant.

 5.The extinguishant is then forced up the syphon tube, through the head cap and hose onto the fire

Fire and safety

To achieve maximum effect, the quantity of heat energy absorbed should be as great as possible. The properties of a good cooling agent are therefore:

• High specific heat capacity (thermal capacity)
• High latent heat of vaporisation
• High heat of decomposition

Water is a good cooling agent because of its high thermal capacity and latent heat of vaporisation. This, combined with the fact it is available in large quantities, makes it by far the most widely useful fire extinguishing agent.

The role of decomposition is insignificant in the case of water but very relevant with certain substances, such as carbon dioxide, that absorb heat in this way.

Smothering

If the oxygen supply to the burning material can be sufficiently reduced, burning will cease. The general procedure is to prevent fresh air from reaching the seat of the fire, allowing the combustion to reduce the oxygen content in the confined atmosphere until it extinguishes itself, for example by:

• Snuffing out candles
• Smothering a pan with a fire blanket
• Wrapping a person in a fire blanket
• Applying a blanket of foam over the burning surface, thus separating the fuel from the air

Smothering can also be achieved by removing the oxygen in the atmosphere, thus extinguishing the fire, for example, by:

• Introducing carbon dioxide (CO₂) to the immediate vicinity of the fire
• Introducing an inert gas to the immediate vicinity of the fire, such as through systems installed to protect computer server rooms

Starvation

In some cases, a fire can be extinguished simply by removing the fuel source. This may be accomplished in a number of ways, such as stopping the flow of liquid or gaseous fuel, removing solid fuel in the path of the fire or allowing the fire to burn until all of the fuel is consumed.

Fires can be starved of fuel by removing potential fuel from the vicinity of the fire, for example:

• Back burning forestry fires
• Draining fuel from burning oil tanks
• Removing cargo from a ship's hold
• Creating firebreaks in peat, heathland and forest fires
• Removing vehicles in the proximity of the fire
• Creating firebreaks in thatch roofs
• Removing tyres not affected by the fire from a tyre dump

Interrupting the combustion process

Dry powder, Bromochlorodifluoromethane (BCF) and other halon extinguishers work by releasing atoms that interrupt the chemical chain reaction. They also create an inert gas barrier.

General safety instructions for construction work

Safety oath 

I solemnly promise that I will do everything possible to prevent accidents, and occupational diseases, and to protect the environment, in the interest of myself, my family, my society and the nation.

 

1.  Always wear helmet and shoes in the workplace, always keep the helmet chin strap on.

 2. Do not do any work without safety equipment.  Obtain the necessary safety equipment from a supervisor before doing any work.  Follow the instructions of the supervisor.

3.It is strictly forbidden to put loose wire in any electrical socket.  Do not do any electrical connection without an electrician.

4.Don't stand under high-hanging items.

5.Do not jump in any moving vehicle. Never set foot on the area around the tires to climb. Use the ladder attached to it. Do not stand behind any moving construction machine. And do not rest in the shadow of any machine. Always be aware of the danger of being crushed by a machine while walking or reversing.

6.Always keep your work place clean and do not spread dirt.  Keep separate all waste  Sach as general waste , hazardous waste, food waste ,wood waste , concrete waste etc

7.While placing the pipe, the pipe does not roll, so that it should be fitted with a choke. When removing the sling, stay on the side of the pipe, not in front of it.

8.When making freight( temporary working platform) after lifting the pipe, first clamp it, only then open the rope.  So  that no one gets hurt if the pipe falls.  The person giving the pipe should also take care of this

9.When concrete with a bomb placer, use a rope to guide the hose of the boom placer.  Do not guide by holding with your hands.  There is a risk of shock and fall.

10.When stacking pipe or spool, provide adequate support near the bend/elbow so that the pipe or spool does not roll/topple.

11.While pulling a pipe or spool on a pipe rake, never stand in front of it. There is a risk of injury by rotating the pipe.

12.When working around electrical wires, always keep a safe distance from them.
