Radiography Works Hazards and Control Measures

Radiography Works Hazards and Control Measures

Introduction

Radiography plays an important role in ensuring safety and quality in construction sites. Radiography is the process of creating an image of the internal structure of an object using X-rays or gamma rays. This technique is commonly used in the construction industry to detect and identify any flaws or defects in the structural components of buildings, bridges, pipelines, and other infrastructure.

Most Common usage of Radiography

Radiography is a non-destructive testing (NDT) technique that allows construction engineers and contractors to assess the integrity of structural components without damaging them. Radiography works by projecting a beam of X-rays or gamma rays through the object being tested, and then capturing the resulting image on a film or digital detector. This image can then be analyzed to identify any defects, such as cracks, voids, or other irregularities that could compromise the safety and stability of the structure.

Hydrostatic and Pneumatic Pressure Testing Procedures Safety

 

Hydrostatic and Pneumatic pressure testing Procedures Safety

Chemical plant equipment such as pressure vessels, heat exchangers, columns. Pipelines, etc., need to be inspected, such as after completion of manufacture or install at regular intervals before commissioning and during plant operations, such as ensuring legal regulations and safe operation.

Testing methods are usually hydrostatic and pneumatic tests. In addition to the rare test "helium test", pneumatic tests are also widely used to minimize down time and economy and to facilitate testing. Compared to which there are hydrostatic tests. It is also useful in detecting very fine juice pathways that cannot be found in hydrostatic tests. However, it is not as safe as hydrostatic for the reasons which are listed at the las of this article.

 

Hydrostatic pressure test is a common non-destructive test method used for testing after piping and pressure vessel construction. This method is often preferred by the owner due to product consideration.

Hydrostatic pressure test example is hydrogen peroxide testing for a pipe line or tank. Since hydrogen peroxide is very sensitive to pollutants, it is best to use this method.

Hazards & Safety concerns during hydrostatic testing

However, in the safety frame, there is a potential risk in the hydrostatic pressure test. It can cause injury and death as well as damage to property if not handled properly.

 

Hydrostatic pressure test uses water at high pressure. The applied pressure is 1.5 times

Excavation hazards and control measures on a work place

                                 Excavation Safety on a work place

Introduction

Excavation is the process of removing earth, rocks, or other materials from a site to create a hole, trench, or foundation. It is a common practice in construction and civil engineering. Excavation can be a dangerous activity, and proper safety measures must be taken to prevent accidents and injuries. In this article, we will explore the various types of excavation, the equipment used, and the safety measures that must be taken to ensure safe excavation practices.

Types of Excavation

There are several types of excavation, each with its own purpose and method. The following are the most common types of excavation:

Trench Excavation

Trench excavation is used to create a narrow and deep hole in the ground. It is often used in utility installation, such as water and sewer lines. Trenches are typically dug using an excavator or backhoe.

Basement Excavation

Basement excavation is used to create a space below ground level that can be used for a basement. This type of excavation requires careful planning and must take into consideration the soil composition and groundwater level.

Topsoil Excavation

Topsoil excavation involves the removal of the top layer of soil. This type of excavation is often used in landscaping and agricultural projects.

Equipment Used for Excavation

Excavation requires specialized equipment to be performed safely and efficiently. The following are the most common pieces of equipment used for excavation:

Excavator

An excavator is a large machine that is used for digging and moving earth. It is equipped with a bucket that can be used to remove soil, rocks, and other materials.

Backhoe

A backhoe is a smaller machine that is used for digging and moving earth. It is equipped with a bucket and a digging arm that can be used to remove soil, rocks, and other materials.

Bulldozer

A bulldozer is a heavy machine that is used to push earth and other materials. It is often used in larger excavation projects, such as road construction.

Skid Steer Loader

A skid steer loader is a small machine that is used for digging and moving earth. It is equipped with a bucket that can be used to remove soil, rocks, and other materials.

Safety Measures for Excavation

Excavation can be a dangerous activity, and proper safety measures must be taken to prevent accidents and injuries. The following are some of the safety measures that must be taken for safe excavation practices:

Site Inspection

Before excavation begins, the site must be inspected to identify potential hazards. This may include underground utilities, unstable soil, or other obstructions that could cause accidents or injuries. The site inspection must be conducted by a qualified professional who has experience in excavation and can identify potential hazards.

Protective Gear / PPE

All workers involved in excavation must wear appropriate protective gear. This includes hard hats, safety glasses, steel-toed boots, and high-visibility clothing. The protective gear must be worn at all times during excavation activities to prevent injuries.

Training

All workers involved in excavation must be properly trained on the equipment and safety procedures. This includes proper operation of the equipment, proper use of safety gear, and emergency procedures. Workers must be trained on how to recognize hazards and what to do in case of an emergency.

Equipment

Excavation requires specialized equipment to be performed safely and efficiently. The equipment must be inspected before each use to ensure that it is in good working condition. Any damaged equipment must be repaired or replaced before it can be used.

Safety Barriers

Safety barriers must be used to prevent workers and equipment from falling into the excavation site. The barriers must be installed around the perimeter of the excavation site and must be clearly marked to ensure that workers are aware of their location.

Sloping and Benching

Sloping and benching are two methods used to stabilize the sides of the excavation site. Sloping involves excavating at an angle to reduce the risk of collapse, while benching involves creating a series of steps to stabilize the sides of the excavation site. The slope or bench angle must be determined by a qualified professional and must be based on the soil type and other site conditions.

Shoring

Shoring involves installing temporary support systems to prevent the sides of the excavation site from collapsing. Shoring systems must be designed and installed by a qualified professional and must be inspected before each use to ensure that they are in good working condition.
