What is a confined space?
Confined Infinite refers to any identify, including whatsoever vessel, tank, container, pit, bund, sleeping room, cellar or any other similar space which, past virtue of its enclosed nature, creates conditions that give rise to a likelihood of an accident, impairment or injury of such a nature as to require emergency activeness due to
- the presence or reasonable foreseeable presence of:
- flammable or explosive atmospheres
- harmful gas, fume or vapour
- gratis flowing solid or an increasing level of liquid
- excess of oxygen
- excessively loftier temperature - the lack or reasonably foreseeable lack of oxygen

What are the key characteristics which define a confined space?
The key characteristics of a bars space are:
- the space must be substantially enclosed
- there must be a risk of at to the lowest degree ane of the hazards listed above occurring within the space
- the risk of serious injury from the take a chance must be created past virtue of the enclosed nature of the space
- the potential injury must exist serious and exist such every bit to require emergency activity to rescue the person involved.

What are the hazards associated with bars spaces?
The hazards associated confined spaces include:
- Toxic Atmosphere
A toxic atmosphere may cause various acute effects, including impairment of sentence, unconsciousness and expiry. A toxic atmosphere may occur due to the presence or ingress of hazardous substances. These substances may be nowadays in the Confined Space for diverse reasons such as:
- remaining from previous processing or storage
- arising from the disturbance of sludge and other deposits
- the presence of a fire or flames inside the space
- seepage from improperly isolated adjoining institute
- formation during the work processes carried out in the space
- existence released from under calibration and in brickwork every bit a effect of the work procedure - Oxygen Deficiency
Oxygen tin can be lacking a confined space for the post-obit reasons:
- displacement of air by another gas
- various biological processes or chemical reactions (such as rotting of organic thing, rusting of metals, called-for, etc)
- absorption of air onto steel surfaces, specially where these are damp - Oxygen Enrichment
An excess of oxygen, in the presence of combustible materials, results in an increased risk of fire and explosion. Some materials, which do non burn in air, may burn vigorously or fifty-fifty spontaneously in an enriched oxygen atmosphere. - Flammable or Explosive Atmospheres
A combustible temper presents a run a risk of fire or explosion. Such an atmosphere can arise from the presence in the confined space of flammable liquids or gases or of a intermission of combustible grit in air. If a flammable atmosphere inside a confined infinite ignites, an explosion may occur, resulting in the expulsion of hot gases and the disintegration of the structure. - Flowing Liquid or Free Flowing Solids
Liquids or solids can catamenia into the confined space causing drowning, suffocation, burns and other injuries. Solids in pulverisation course may besides be disturbed in a confined space resulting in an asphyxiating temper. - Excessive Rut
The enclosed nature of a confined space tin increment the risk of heat stroke or collapse from heat stress, if conditions are excessively hot. The risk may be exacerbated by the wearing of personal protective equipment or past lack of ventilation

What are the legal requirements in regard to confined space entry?
The Condom, Health and Welfare at Work (Confined Spaces) Regulations 2001 cover all piece of work in relation to bars spaces.
Regulation five states that:
- A person shall not acquit out work in Confined Spaces if information technology is reasonably practical that it could be avoided
- If the piece of 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 infinite unless there is a system of work in place that has been planned, organised, performed and maintained so every bit to return 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 piece of work activities

What are legal requirements in relation to Emergency Arrangements for confined spaces?
Regulation 6 of the Confined Space Regulations 2001 states that:
- A person shall not enter a confined infinite unless there is a suitable emergency arrangements take been made which are appropriate to the confined space in question
- The emergency arrangements shall include:
- all practical measures necessary to ensure the wellness and safety of those taking part in the rescue
- the provision of a suitable and reliable means of raising the warning in the result of an emergency
- having all necessary rescue equipment nearby and in a well maintained, good condition
- the provision of information, educational activity and training to all involved in rescue procedures
- the provision of equipment and preparation for resuscitation procedures if there is a foreseeable hazard that they volition be needed.

What must I look for in a confined space risk assessment?
When conveying out a risk assessment information technology is important to ensure that all risks associated with the hazards in a higher place are evaluated and controlled. When carrying out a take chances assessment the post-obit questions should be asked:
- What could be within the infinite that would pose a risk?
- Contents?
- Oxygen Deficiency?
- Previous Contents?
- Oxygen Enrichment?
- Residues?
- Structure and Layout?
- Contamination? - What will be created due to the work carried out in the space?
- Sources of Ignition?
- Flammable Substances? - What's outside the space that might pose a risk during the proposed work?
- Inadequate Isolation?
- Inadvertent Functioning Of Plant?
- Nearby Work Activities?

Are there any exemptions from the Safety, Health and Welfare (Confined Spaces) Regulations 2001?
Yep. The regulations do non apply to any place below ground in a mine (every bit divers past the Mines and Quarries Act 1965) or to any diving operations.

What are the key elements of a prophylactic arrangement of work for a confined space?
The fundamental elements to exist considered when drawing up a safe system of piece of work are:
- Competence, training, supervision and suitability
- Permit-to-piece of work procedure
- Gas purging and ventilation
- Dangerous residues
- Testing and monitoring of the atmosphere
- Mechanical, electrical and procedure isolation
- Respiratory protective equipment
- Other personal protective equipment
- Safe employ of work equipment
- Communications
- Admission and egress
- Flammable or explosive atmospheres
- Flammable materials

What is a permit-to-work procedure?
A let to work procedure is a means of achieving effective control of a organization of work through formal written documentation known every bit a permit to piece of work form. The essential components of a permit-to-work organisation include:
- A written procedure, which sets out how the system is to operate and clearly defines who may authorise particular jobs and who is responsible for specifying and implementing the necessary precautions
- A form, known as the "permit-to-work form", which becomes a written and signed statement ensuring both the establishment of prophylactic conditions for the work to embark and the maintenance of safe weather condition for the duration of the piece of work, including the provision of emergency arrangements
- A method of informing the persons conveying out the piece of work of the exact identity, location, nature and extent of the chore, the hazards involved and the precautions to be taken, and
- A system for ensuring the condom hand-back of the workplace after the job is completed and, in the case of bars space entry, later the space is vacated
