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.

Construction Permit to Work System

 

Construction Permit to Work System

Introduction

The construction industry is one of the most hazardous industries in the world. Workers in this industry are exposed to a wide range of hazards, including falls, electrical hazards, chemical exposure, and machinery-related accidents. The construction permit-to-work (PTW) system is a set of procedures used to regulate high-risk activities in the construction industry. The purpose of this system is to ensure that all work is completed safely, and all risks are identified and managed.

Background

The construction industry is a vital sector of the global economy. It is responsible for the creation of buildings, bridges, roads, and other infrastructure that enable economic growth and social development. However, construction work is also one of the most hazardous industries, with a high rate of accidents, injuries, and fatalities. The construction PTW system

Accident Investigation on a workplace

 

Accident Investigation

 

Accident Investigation



 

Workplace accident investigation is an ideal tool identify the outcomes which will arise after the accident. 

Why do you need to investigate occupational accidents?

For identification the cause of incident.

To prevent comparative accidents later

To meet legal needs.

To determine the cost of an accident

Determines the consistency of product safety guidelines.

To process a worker's payment request

In either case, you should investigate the event, which does not include injury or property damage, to determine which risks need to be adjusted. Don't believe you are twice as happy. 

It is important for the organization to review the accident concisely at the moment of the actual accident occur.

Inappropriate or false investigations can confuse the problem and increase the expected risk. Accident investigations are conducted by health and safety experts who visit the site to understand the current reality. 

The purpose of accident investigation is to avoid reoccurrence.

Similar accidents can occur later if you can’t able to find the reason for the accident once you have done the identification you can easily find a way to control or eliminate it.

Frustration is rarely a reason of an accident. Workplaces, work restrictions, management issues or lack of work experience can be the reasons of an incident.

You need to examine all these to determine what is the reason behind the incident, once identified we can eliminate it or control it. 

Once the cause is identified, precautions should be taken and applied to prevent recurrence. HSE Officers should always remember that successful accident investigation involves finding the truth, not the errors. 

To explain why and how the accident happened? Safety officers need to collect data about incident that occurred before and during the incident. The safety officers were then able to determine the circumstances of the incident /accident by looking at the actual evidence and meeting with the witness. It is important to kept the record of the steps taken after the accident.

 Three things we need to consider for preventing accidents.

1.     The data which we collect needs to be investigated adequately. 

2.     A recovery drill needs to be conducted.

3.     All the activities must be adhered with local legislative.

 

Important measures which need to be consider for accident investigation.

Your organization's safety and health for the projects should include the following things for Accident Investigation.

 

What type of error do you need to investigate?

Who needs to investigate and what needs to be investigated?

What kind of preparation do safety officers need to make investigation?

Who examines the report and provides awareness and suggestions?

Do I Need a medical treatment for all injury/Wounds?

Incident lead to property damage?

Are there any accidents that could cause real injuries or serious financial accidents? 

Reportable accident

All the accidents that will in result of serious injury need to be reported to the Ministry of labor (MOL). It is a legal requirement to report it to concern authorities. Ministry will then issue the advisory to all the related parties to avoid the reoccurrence.

Unsafe Work Conditions with examples at a workplace

 

 

Unsafe Conditions at Workplace

 

Unsafe Work Conditions

Unsafe Conditions Examples

 

An accident may occur due to the unsafe conditions. Few of them as an example are:

Uncomfortable Environment which may be Hot, Noisy etc..

Inadequate designed machines or inadequate design of tools.

Poor housekeeping inadequate access routes.

Due to uneven surface which can be rough, slippery or defective in any way.

Poor or insufficient lighting conditions.

Improper ventilation or air quality is not good (contaminated air)

Poor guarding of machine or equipment’s.

Unguarded machinery or equipments or lack of guards.

Unsafe processes or method of completing the task - mechanical, chemical, electrical, and nuclear.

 

This does not mean that an unsafe operation or unsafe condition alone cannot lead to an accident.

For example, horse play is an unsafe process that may occur in safe situations, but It can still cause an accident.

In the same way, a person can work perfectly, Safely, using safe equipment and materials that are in good condition, but prone to injuries.

 

 

Temperature

 

Many experiments have been done on the impact of temperature. The main variables are air temperature, moisture, air flow and operator's clothing and task. The general consensus is that the conditions for thermal comfort, work performance and minimum accidents are identical. The temperature in the range of 16-24 ° C is acceptable to most people.

 

Noise

The effect of noise is very complex. It is identified that noise can damage the hearing mechanism and prolonged exposure to noise levels above 120 dB (decibels) can cause permanent damage.

Lower levels interfere with speech and communication may interfere with work performance. Errors have been found to increase with noise and non-hearing effects, Any of these effects could easily be responsible for an accident.


Mechanical

For many years, machinery is responsible for many industrial accidents around the world.

Through government law enforcement, and improving the awareness about guarding, agronomic design and moral and social responsibilities, which has reduced the number of injuries from machinery related accidents.

It still leaves a lot of concern, because machine accident injuries are generally intense, and often cause partial or even permanent disability.

Although the safety rules of fencing and dangerous machinery are present, most accidents are due to the use of improper guards or failure to use the guards provided.

However, all the guards should be designed well, should be adjusted correctly, properly maintained and examined regularly.

Some machines can remain unsafe because they are considered as 'safe' in terms of position.

No machinery can really be protected by position because its relative safety depends on the proximity of people.

 

Its the supervisor who can carefully examine in the beginning and after completion of the work, to removing the fuse, locking the start switch or covering, and place an appropriate notice sign.

 

Physical

Industrial psychologists have just done a lot of time to review how the operator's performance varies, as the external conditions change, the idea is that there is a great bet to perform all kinds of work. For example, when the lighting, heating, ventilation, moisture and noise conditions are found to be found, it has been found that there is some desired range inside which the operator will work efficiently.

Anything outside this range, either very little or much more, its performance will affect its performance. However, many workers will try extra to maintain the production despite the worsening conditions. In such cases it has been found that it usually increases the frequency and intensity of accidents.

Unsafe Acts at workplace with examples and types of Unsafe Acts at a workplace

 

Unsafe Acts at Workplace


Unsafe Act at Workplace




Let's start with an example to better understand the unsafe acts. In a MEP store, pipes of some lengths were being stacked.

Same time morning tea break starts.

The workers who were stacking quickly finished their work and went for tea.

After tea, they resumed work in the other part of the store.

Unfortunately, they left some pipes in the first stack and these pipes are in the access area.

Later, at sunset, another employee arrived, turn the yard lights on, and slipped over the faulty stacked pipes.

 

 

 

In another example, in the same area, one of the other workers used a defective tool, resulting in an injury to his hand.

In the result of an investigations observed that the tool was damaged and rusty and the worker tries to fix it on his own, which he is not capable of.

In both cases, the accident occurred due to an unsafe operation. In one case, a third party was injured. In the second, the unsafe act was committed by the injured party.

 

 

Unsafe Acts Examples

 

Unsafe acts of the personal may be considered as following:

Operating the tools and equipments when not authorized.

Working at unsafe speed .

Bypass the safety devices.

Using unsafe tool and equipment, or using it in an unsafe manner.

Working in unsafe methods.

Unsafe position or posture while working.

Working while moving or dangerous equipment used.

Horseplay, while working.

Failure to wear PPE (personal protective equipments).

Lack of attention; routine activity without thought.

 

Unsafe Act Types

 

From an accident prevention perspective, it is helpful to categorize the unsafe acts into two types:

 

Active and inactive

 

Active Unsafe Act.

A clear example of the active nature of the unsafe act is the case where a worker intentionally.

Removes a protective shield to potentially improve its production rate. This act, together with

The fact that he is working faster now can cause more mistakes. Many of them may go unnoticed, some may cause faults, but ultimately, On average, there will be an accident at the end.

Of course, it is difficult to control a person's behavior, but the most effective measures are to proceed with proper training and proper supervision.

 

Inactive Unsafe Acts.

Inactive unsafe acts are usually more difficult to deal with. for an example.

Failure to wear an employee's personal protection when clearly everyone knows they have to wear before commencing the activity. There will be lot of possible reasons for not wearing.

Inactive movements are often very difficult to change. This can be done by counseling schemes, training programs and with effective monitoring.
