Excavations

Excavations are a very dangerous high risk construction activity. The Safety, Health and Welfare at Work Act 2005 requires a risk assessment to be performed by contractors before undertaking any excavation work. The risk assessment must:

• identify those hazards that are likely to be encountered;
• determine the control measures; and
• determine the safe system of work required to protect employees and persons affected by the activities taking place.

Control measures selected could be in the form of shoring (support for the excavation), battering (sloping the excavation) or other suitable means.

In addition, the Construction Regulations require contractors to guard against the dangers from a fall or dislodgement of material in an excavation.

 

Before Excavations Activates Start

Before excavations even take place, some planning has to take place. For example, we must plan to prevent danger to workers in or near excavations. To maintain the required precautions, a competent person must inspect excavation supports or battering at the start of the working shift and at other specified times. No work should take place until the excavation is safe. Furthermore, sufficient numbers of trained staff and adequate supervision must be present on site before works start. Additionally, sufficient and suitable plant and equipment for trench support must be on site before work starts. Information on ground conditions and location of existing services must be obtained before work starts.

 

Excavations and Basic Control Measures

To implement basic excavation control measures a competent person would need to decide what temporary support will be required and plan the precautions to be taken. Another key point to consider is the presence of any buried services. These must be addressed before excavation works begin. Signs and barriers must be provided to cordon off the place of work and precaution must be taken when considering location of excavated spoil and any material delivered to the site.

 

Excavations Related Management Procedures

To successfully manage any excavations activities, certain systems must be implemented. For example, a safe system of works must be provided taking into account weather, traffic conditions and existing structures. In addition, suitable personal protective equipment (PPE) must be provided.  A competent person must inspect excavations:

• At least once in every day during which persons are at work there.
• If more than 2 metres deep, at the start of each shift before work begins.
• After any event likely to have affected the strength or stability of the excavation or the shoring.
• After any accidental fall of rock, earth or other material.
• At least once every 7 days where persons are not at work there.

 

Training Requirements

Supervisors must be trained in the theory and practice of excavation work. In addition, they should be aware of COSHH regulations and requirements. Workers must be trained in excavation support procedures appropriate to the work method selected. To help with raising general workplace safety awareness, the eLearn Safety has developed a fully online Workplace Safety – Level 1 course. This course is ideal for every employee in any workplace that’s subject to Health & Safety Legislation. Safety in the workplace is everyone’s responsibility. It provides all employees who participate on this course with information on how to identify hazards and carry out simple risk assessments.

In addition, the HSA has published a range of useful information about excavations safety. This information can be accessed via their web page title Working in Excavations-Frequently Asked Questions.

In addition, Health and Safety Executive (UK) has published a number of useful information about excavations. This information can be accessed via their webpage Excavations.

 

Online Health and Safety Training

Proactive Health and Safety training is critical to ensure a safe workplace. An effective training program can reduce the number of worker injuries and deaths. It can also reduce instances of property damage, legal liability, illnesses, and missed time from work.

Health and Safety training helps establish a culture in which employees themselves help promote proper safety procedures while on the job. It is important that new employees be properly trained and embrace the importance of workplace safety. The role of training in developing and maintaining effective hazard control activities is a proven and successful method of intervention.

This is why we have established eLearn Safety school. We pride ourselves in how we guide, support and mentor our students. They receive support throughout their learning experience and into their working lives. Our staff have extensive training experience and also have many years industry experience. We understand the challenges that exist within Environmental and Occupational Health and Safety. Our priority is to ensure that all learners are fully prepared to differentiate themselves in the workplace after completing our Health and Safety courses.

Working in Confined Spaces

Working in confined spaces is a high risk working environment.

 

What does it mean Working in Confined Space

Any significantly enclosed space where there is a risk of death or serious injury from hazardous substances, lack of oxygen or other dangerous conditions is classed as a confined space. Confined spaces with small openings such as silos, drains, sewers and storage tanks are fairly obvious. Others are not. Ductwork, vats, open-topped chambers may be less obvious.

 

Before Working in Confined Space Commence

Before working in confined space commences, certain steps should be taken. All hazards present must be identified and the risks assessed. This information should then be used to determine what precautions are needed and safety procedures developed (including emergency rescue).

 

Confined Space Entry

If working in confined spaces can be avoided – it should be avoided.

According to the Health and Safety Authority of Ireland and the Safety, Health and Welfare at Work (Confined Spaces) Regulations 2001, Regulation 5 states that:

A person shall not carry out work in Confined Spaces if it is reasonably practicable that it could be avoided.

If the work must be carried out Hazard Identification and Risk Assessment must be carried out prior to the work commencing.

A person shall not enter a confined space unless there is a system of work in place that has been planned, organised, performed and maintained so as to render that work safe and without risk to health.

Anyone entering a confined space must be provided with appropriate information, training and instruction appropriate to the particular characteristics of the proposed work activities.

 

Questions to Ask

Before working in confined space commence, the following should be considered:

If someone is working in a confined space, think about the following:

• If a worker gets overcome by fumes how will anyone know this is happening?
• Once workers become overcome by fumes how can they be rescued?

Always:

• Make sure you are fully aware of all the risks associated with working in confined space!
• Make sure that the person performing work in confined space is competent (capable and trained) to work in confined spaces and in use of emergency equipment.

Never:

• Work in confined spaces if it can be avoided.
• Let unskilled people engage in confined space work.
• Let anyone enter confined space unless sure it is safe to do so.
• NEVER ignore risks associated with working in confined space.

 

Useful Resources

The Health and Safety Authority of Ireland (HSA) has a very useful info page titled Working in Confined Spaces. This page covers some of the most frequently asked questions about working in confined spaces.

In addition, the UK’s Health and Safety Executive info page titled Introduction to working in confined spaces can provide additional very useful information about working in confined spaces.

 

Tragic Example

As The Irish Times reported; on June 10th, 2015 brothers Alan (45) and Stephen Harris (32) were overcome by fumes while working in an underground sewer at Drumnigh Woods, Portmarnock, Co Dublin. They were taken from the sewer and taken to hospital but unfortunately died of hypoxia due to toxic levels of hydrogen sulphide.

The brothers were wearing wader boots and rain jackets and Stephen Harris was wearing a dust mask.

A toxic gas incident that claimed the lives of two brothers almost killed a fireman attempting to rescue them.

How It Could Have Been Avoided

Health and Safety Authority inspector Frank Kerins said the job required specialist equipment in accordance with confined space regulations, including a gas detector and breathing apparatus.
