Administrative Issues in workplace compliance services

To keep your working environment safe and hassle free you may try to following administrative issues in your workplace.

Manual Handling

Welfare Facilities

First Aid

Accident Reporting

PPE

Emergencies

Manual Handling: Manual handling is important and need to aim individuals who undertake any manual handling activities at work. Every day manual handling properly in work place many risk may keep control. Manual handling is issue to how look carefully at their own work activities and contribute to the development of safer methods and tasks in co-operation with their managers and supervisors, with the aim of reducing injuries.

Welfare Facilities: Construction workers need adequate toilet and washing facilities, a place to warm up and eat their food and somewhere to store clothing. However, these basic requirements are often neglected. A cold water tap and chemical toilet on their own are not adequate facilities. Good welfare facilities can positively benefit health.

First Aid: First aid requirements may vary from one workplace to the others, depending on the nature of the work, the type of hazards, the workplace size and location, as well as the number of people at the workplace. Administrator of the workplace must consider these factors to take into account when deciding what first aid arrangements need to be provided.

Accident Reporting: There must be a process put in place to report accidents, incidents or near misses for immediate action and to help track causes. The organization needs to identify what needs to be reported, to whom it is to be reported, and how to report it, then put this process into a written procedure.

PPE: Suppliant numbers and types of PPE- personal protective equipment must available near workplace is to reduce employee exposure to hazards when engineering and administrative controls are not feasible or effective to reduce these risks to acceptable levels. PPE is needed when there are hazards present. PPE has the serious limitation that it does not eliminate the hazard at source and may result in employees being exposed to the hazard if the equipment fails.

Emergencies: It is important to educate employees on workplace fire escape plans. Explain the best possible way to exit the workplace, which exits are closest to them and where the alternative exits are located. Decide on a place for employee to meet once everyone has exited the workplace. Hold a practice fire drill at least once every month.

How Control Working Site Traffic, Vehicles and Plant in Construction Site?

Site Traffic, Vehicle and Plant Control Procedure at Construction Working Site 

Moving vehicles and equipment on construction sites can be fatal if not used correctly and safely. As the elimination of mobile plant hazards is unlikely to be an option on a construction site, hazards must be isolated or minimized by implementing the following traffic control measures. Develop a traffic management plan including control measures to suit the specific requirements of the construction site. The implementation of a combination of control measures is likely to be the most effective means of managing the traffic hazard from mobile plant.

Loading, Storage and Parking

Where conditions allow position contractor parking near to the site complex welfare facilities - this will reduce the amount of vehicle and pedestrian movement across site

Loading and storage areas should be located away from the main work areas, have a clear entrance and exit point and use a one way system if possible. There should be sufficient room for delivery vehicles to man oeuvre and safe areas for those unloading / loading materials.

Loads - ensure loads are securely attached to vehicles and that loose material such as bricks and lumps of clay cannot fall from Lorries / site dumpers and strike pedestrians.

Do not overload vehicles, they become unstable, difficult to steer and the braking becomes less effect.

Load and unloads vehicles in the correct manner.

Sponsored:

Signs and Lighting:

The use of signs and well lit vehicle and pedestrian routes are necessary on most construction projects.  Clear well positioned signs help reduce potential confusion for drivers and pedestrians when trying to move around site.

Further consideration must be given to lighting during the winter period when shorter daylight hours often means sites are starting and finishing in the dark.

Note; Signs located on the public highway must conform to Department for Transport Standards in relation to size, spacing / position and reflective values.

Surrounding Environment:

During the planning and construction phases consideration must be given the surrounding transport network. 

The roads used to approach the site have an essential part to play in ensuring safe access and in keeping the local community traffic flow moving.

Sometimes it is necessary to re-direct site traffic via a particular route to avoid a school, congested road, height and weight restrictions on bridges etc.

When working with SITE VEHICLES, check:

Check the following points related to controlling site traffic, vehicles and plant in construction site keep your to keep your workplace safe. Are vehicles and workers kept apart by using barriers

Warn visitors of the presence of construction site traffic.

There are warning signs regarding site traffic displayed.

There is adequate clearance around slewing machines.

Properly trained banks men are used to guide reversing vehicles.

The presence of the required safety signs to keep pedestrian & traffic away from site works.

Office Refurbishment and Healthy Work Place

What Would be the Office Refurbishment and Healthy Work Place?

First we need to think about what a ‘healthy’ workplace is. It can be many things; a place where employees feel recognised for the work they do; enjoy a happy work-life balance; have access to opportunities to adopt healthy lifestyle practices and coping with skills to manage lives in a healthy, productive way; and are given opportunities for personal, intellectual and professional growth.We have to know too well that it’s possible to provide a pleasant, healthy, happy office environment for everyone. So when you’re planning your office fit-out or office refurbishment, consider the work styles and welfare of your staff early on to achieve a healthy, happy and harmonious environment for everyone.

High value components are often used at production plants or other technical objects (for example, pumps, motors) and are replaced by a repairable spare in the event of a malfunction and then refurbished using a separate order.

This scenario is of particular interest to companies for which system availability plays a crucial role (for example, process industry, oil extraction and processing, steel manufacturing and so on), and who keep repairable spares in stock to ensure a high system availability. The refurbishment of these defective spares, which are generally of high value, is of great economic importance for these companies and is often a core process within their maintenance department.

An office refurbishment is an exciting opportunity to refresh your workspace without the added complications of moving.

Creating a refurbishment order: 

When the number of defective repairable spares in the warehouse has reached a certain level, the maintenance planner in charge creates a refurbishment order.  The planner defines the time-frame for the refurbishment and plans all the operations materials, tools, etc. required for the refurbishment.

If REFURBISHMENT is carried out, check the following:

For falling objects onto people below?

All non-essential service is cut-off?

All holes created or opened are clearly signposted and covered securely?

There is sufficient safety signs to warn of dangers?

Adequate ventilation is provided especially in painting work?

Good housekeeping rules are followed?

The Benefits of Office Refurbishment

It is well known that individuals work faster and more efficiently in creative spaces, designed with work output in mind. In fact, 60% of individuals agreed that their office environment impacted their levels of motivation in the workplace.

Improve your image to clients & prospects

Just as your people sell your business, so does your office. Think about what visitors to your office see on arrival: a tired and dated workplace for a tired and dated company or a fresh and vibrant office for a forward-looking business? Your office is a blank canvas, so use it to your advantage.
