High risk work activities account for a disproportionate share of UK workplace fatalities and serious injuries each year. Falls from height, confined space incidents, and accidents involving hazardous substances and energised systems are among the most dangerous situations workers face. Employers have a legal duty under the Health and Safety at Work etc. Act 1974 to ensure that anyone undertaking high risk work activities is appropriately trained, competent, and supported by safe systems of work. This training hub covers the key high risk work areas: working at height, confined spaces, explosive atmospheres, scaffolding, temporary works, harness and lanyard safety, lone workers, rope access, and EUSR utility safety passports. Classroom, online and on-site delivery options are available for individuals and organisations of all sizes.

Training areas

Working at height training

Work at Height Regulations 2005

⚖ Legal requirement

Falls from height remain the single biggest cause of workplace fatalities in the UK. The Work at Height Regulations 2005 require employers to ensure all work at height is properly planned, supervised and carried out by competent people using appropriate equipment. Training covers risk assessment, equipment selection, fall prevention and emergency procedures.

Confined spaces training

Confined Spaces Regulations 1997

⚖ Legal requirement

Confined space incidents have an exceptionally high fatality rate — many deaths occur when untrained bystanders attempt rescues. The Confined Spaces Regulations 1997 require employers to avoid confined space entry where possible, and where entry is unavoidable, to follow a safe system of work using competent, trained personnel. Training covers atmospheric testing, emergency procedures, breathing apparatus and rescue techniques.

Explosive atmospheres (DSEAR)

Dangerous Substances & Explosive Atmospheres Regulations 2002

⚖ Legal requirement

Where a process generates combustible dust or handles flammable substances, DSEAR applies alongside general fire safety law. Duty holders must carry out a separate risk assessment under Regulation 5, classify hazardous places into zones and select equipment to match. A small primary event can disturb settled dust and trigger a far larger secondary explosion, which is why housekeeping and zoning are treated as controls rather than good practice. Relevant to timber, food and feed, milling, metal fabrication and waste processing.

Scaffolding training

Work at Height Regulations 2005 / Construction (Design & Management) Regulations 2015

⚖ Legal requirement

Scaffolding must be erected, altered and dismantled by competent personnel, and inspected before use and after any event that may have affected its stability. Scaffold inspection training is essential for site supervisors and managers responsible for authorising scaffold use. Courses range from one-day awareness through to detailed three-day scaffold inspection qualifications.

Temporary works training

BS 5975 / Construction (Design & Management) Regulations 2015

⚖ Industry standard

Excavation support, falsework, formwork, propping and façade retention hold loads that the permanent structure is not yet carrying, and collapses tend to be sudden and to affect everyone nearby. CDM 2015 applies to temporary works exactly as it does to the permanent structure; BS 5975 supplies the procedural framework — register, design brief, design check categories and the appointment of a coordinator. Most principal contractors require that appointment contractually.

Harness & lanyard safety

Work at Height Regulations 2005 / PUWER 1998

⚖ Legal requirement

Personal fall protection equipment — harnesses, lanyards, inertia reels and anchor points — must be inspected before every use and formally examined at regular intervals. Incorrectly fitted or poorly maintained harnesses provide little or no protection. Training covers selection, fitting, pre-use checks, formal inspection and record-keeping requirements under PUWER.

Lone worker safety

Health and Safety at Work etc. Act 1974 / Management of H&S at Work Regulations 1999

⚖ Legal requirement

Over 6 million people in the UK work alone at some point during their working day. Employers must assess the specific risks faced by lone workers and put in place appropriate control measures including communication procedures, check-in systems and emergency protocols. Lone workers in high risk environments such as utilities, healthcare and construction face particular challenges requiring specific training.

EUSR safety passport training

Energy & Utility Skills Register (EUSR)

✓ EUSR accredited

EUSR Safety Passports are required for anyone working in the water, power, gas and drainage utility sectors. The scheme ensures workers meet industry-specific safety competency standards before being permitted on site. Cards cover SHEA Water, SHEA Power, SHEA Gas, SHEA Drains & Sewers and National Water Hygiene qualifications.

Rope access training

Work at Height Regulations 2005 / IRATA standards

✓ IRATA standards

Rope access is used across construction, telecommunications, wind energy, inspection and maintenance industries where conventional access equipment is impractical. Training must meet IRATA (Industrial Rope Access Trade Association) standards and covers rope rigging, descent, ascent, rescue techniques and equipment inspection. Rope access operatives must hold a current IRATA card at the appropriate level for their role.

CCNSG safety passport

CCNSG / Engineering Construction Industry

✓ Industry required

The CCNSG Safety Passport is mandatory for anyone working on engineering construction sites in the UK, including oil, gas, petrochemical, power generation, pharmaceutical and process plant sectors. It demonstrates a baseline level of health and safety awareness for site access and must be renewed every three years.

First aid training

Health and Safety (First Aid) Regulations 1981

⚖ Legal requirement

Employers working in high risk environments must carry out a first aid needs assessment and ensure adequate first aid provision. For construction sites, utilities and industrial environments this typically requires trained First Aiders at Work (FAW) rather than just Emergency First Aiders. Rapid, competent first aid response is critical in high risk environments where serious injuries can deteriorate quickly.


Who should attend

Utilities & infrastructure workers
Maintenance & engineering staff
Process & production managers
Health & safety managers
Site supervisors & managers
Confined space entry teams

Why high risk work training matters

Statutory legal duties

The Work at Height Regulations, Confined Spaces Regulations, DSEAR and the Health and Safety at Work Act all impose explicit training and competency requirements. Non-compliance carries unlimited fines and the risk of manslaughter charges where fatalities occur.

Prevent fatalities

Falls from height are the largest single cause of UK workplace fatalities each year. In confined space incidents, a substantial proportion of those killed are would-be rescuers who entered without training or equipment. Training is the primary defence.

Meet site access requirements

CCNSG Safety Passports and EUSR cards are mandatory for site access in engineering construction and utility sectors. Training ensures your workforce can meet contractor and principal contractor access requirements.

Demonstrate due diligence

Following a serious incident, documented training and competency records are a key element of any legal defence. Courts expect employers to demonstrate that risks were identified and that workers were trained to manage them.

Protect lone workers

Lone workers in high risk environments face unique challenges — if an incident occurs there is no immediate colleague to raise the alarm or provide assistance. Training and robust lone worker procedures are both a legal requirement and a moral duty.


Frequently asked questions

A confined space is any place that is substantially enclosed, where there is a reasonably foreseeable risk of serious injury from hazardous substances, conditions or circumstances due to its enclosed nature. This includes manholes, sewers, tunnels, tanks, silos, vessels, ducts, pits and trenches. It does not have to be fully enclosed or small — a large vessel with a restricted opening can still be a confined space.
Yes. The Work at Height Regulations 2005 require employers to ensure that anyone involved in work at height — including planning, supervising and carrying out the work — is competent to do so. Competence means having the skills, knowledge and experience to do the job safely. For most work at height activities this requires formal training.
Whenever a dangerous substance is present that could cause harm by fire or explosion — flammable liquids, gases and vapours, and combustible dusts such as wood, flour, grain, sugar, animal feed, coal and metal powders. DSEAR sits alongside general fire safety law rather than inside it, and requires its own risk assessment under Regulation 5, classification of hazardous places into zones, equipment selected to match the zone, and control of ignition sources. A workplace can be fully compliant on general fire precautions and still have an unassessed explosion risk. Note that most mineral dusts, including silica, are a health hazard rather than an explosion hazard and fall under COSHH instead.
CCNSG Safety Passports are valid for three years from the date of issue. After three years the passport holder must complete a renewal course to maintain their site access qualification. Some principal contractors may impose shorter renewal periods as part of their contractor management requirements.
It depends on the role you hold. The two-day CITB Temporary Works Coordinator course is the Site Safety Plus qualification for those actually appointed as coordinator, with a certificate valid for five years and a one-day refresher to renew it. The one-day Temporary Works Supervisor course is for those checking works on site under a coordinator. The two-hour e-learning course covers awareness of BS 5975 and the CDM duties for designers, managers and client-side staff who need to understand the process without holding the appointment. Where a client or principal contractor specifies TWCTC, only the CITB course meets it.
Confined space training is categorised by risk level. Low risk covers spaces where the primary hazard is limited access and egress. Medium risk covers spaces with potential atmospheric hazards requiring monitoring. High risk covers spaces where breathing apparatus may be required and where the risk of serious injury or fatality is significantly elevated. The City & Guilds 6160 suite of qualifications covers all three levels.
Under PUWER 1998, all personal fall protection equipment must be inspected before each use by the person using it, and formally examined at intervals specified by the manufacturer or a competent person — typically every 6 or 12 months. Any harness that has arrested a fall must be immediately withdrawn from service and replaced, even if no visible damage is apparent.
Yes. Many high risk work courses including confined space entry, working at height, scaffold inspection and harness training can be delivered at your premises or on your site using your own equipment and structures. On-site delivery is particularly beneficial for high risk work as it allows training to be tailored to the specific environments and hazards workers will face in practice.
