Why PSSR Inspections Matter for Businesses in Thorne

Thorne: Location and Background
Thorne is a historic market town situated in the Metropolitan Borough of Doncaster, South Yorkshire, England. It lies on the edge of the Humberhead Levels, an area once characterised by extensive wetlands that were later drained to create fertile agricultural land. The town’s location near the M18 motorway and Stainforth and Keadby Canal has long made it a key transport and trade link between South Yorkshire and the Humber region. Thorne’s history dates back to the Domesday Book, and over the centuries it has evolved from a small agricultural settlement into a community with strong ties to engineering, waterway transport, and manufacturing.

Historic and Traditional Industries
Traditionally, Thorne developed around agriculture, boatbuilding, and peat extraction. The town’s proximity to navigable waterways encouraged the growth of barge and boat repair yards, while nearby peat moors supported the once-thriving peat industry that supplied fuel and horticultural materials throughout the region. During the 20th century, the opening of Thorne Colliery brought a surge in employment and population, with coal mining becoming a dominant local industry. Supporting trades such as engineering, metalwork, and rail freight also expanded during this period, helping to define Thorne as a working-class industrial hub within South Yorkshire’s economic network.

Modern Industry and Economic Development
Today, Thorne has shifted away from traditional heavy industry towards modern logistics, light manufacturing, and distribution. Its excellent transport links—via the M18 motorway, nearby rail connections, and proximity to the M62 corridor—have attracted major warehousing and logistics operations serving national retailers and manufacturers. Local companies specialise in sectors such as plastics production, precision engineering, and storage solutions. Business parks and industrial estates on the outskirts of Thorne, including new developments around Bradholme Farm and Unity Yorkshire, are creating opportunities in renewable energy, transport, and advanced manufacturing. This transition reflects Thorne’s ability to adapt and remain economically relevant in a changing industrial landscape.

Thorne is a market town in South Yorkshire, located to the north-east of Doncaster, near the edge of the Humberhead Levels. It is surrounded by villages and towns such as Moorends, Fishlake, Stainforth, Hatfield, and Goole. The town’s location near rivers, canals, and fertile lowland farmland has historically shaped its development and the economy of the surrounding area. Thorne has traditionally acted as a local centre for trade, agriculture, and industry.

Historically, agriculture was a dominant industry in Thorne and the surrounding villages. The flat, fertile land of the Humberhead Levels supported arable farming, dairy, and livestock, which provided employment and food for the local population. Coal mining also played a role in nearby settlements, such as Hatfield and Stainforth, providing additional jobs and supporting the development of transport and engineering industries. Canals and rivers in the area facilitated the movement of coal, agricultural produce, and other goods to larger markets.

In more recent times, the economy of Thorne and its surrounding villages has diversified. Light manufacturing, logistics, and warehousing have become important employers, supported by good road and rail connections. Retail, education, healthcare, and public services provide further employment for residents, while agriculture continues to be significant in the wider countryside.

Today, Thorne and its neighbouring towns and villages reflect a combination of historic agricultural and industrial heritage with modern economic activity. The area balances rural traditions with light industry, logistics, and commuter-based employment, demonstrating adaptability and ongoing economic development in South Yorkshire.

For these businesses, staying compliant with the Pressure Systems Safety Regulations 2000 (PSSR) is not just a legal requirement—it’s also about safeguarding your employees, protecting your business reputation, and ensuring your equipment remains safe and reliable.

Legal Requirements Under PSSR 2000

PSSR regulations place strict duties on business owners and equipment operators. Any business in Thorne that owns or operates pressure systems and pressure equipment must ensure that:

• Pressure systems and pressure equipment is safe to use.

• A written scheme of examination (WSE) is produced prior to their pressure system being put into service.
• A WSE is required when the pressure volume of the vessel exceeds 250 bar/litre (Pressure x Volume), and a relevant fluid is present, or if there is steam stored in the vessel at any pressure.

• Examinations are carried out in line with their written scheme of examination (WSE) and at regular, legally required intervals.

• Inspections are conducted by a competent and impartial person.

Failure to comply can lead to heavy fines, prosecution, and serious safety risks.

Protecting Your Workforce and Your Business

At SEIS, we know that every business in Thorne – whether in heavy industry, healthcare, education, catering or automotive—depends on reliable, safe equipment. Regular PSSR inspections & PSSR testing reduces the risk of accidents, protects your workforce, and ensures smooth day-to-day operations. Compliance not only keeps you legal, but also demonstrates a strong commitment to employee safety.

What is a Thorough Examination and In Service Examination under PSSR?

A thorough examination & in service examination under PSSR is a detailed and legally required inspection of your pressure system, and the vessels & system protective devices within it. Unlike simple checks or maintenance tasks, a PSSR examination must be performed by an impartial, competent person and results in an official Report of Thorough Examination.

Frequency of Examinations

How often your pressure system in Thorne needs to be inspected & tested depends on its drafted written scheme of examination by the competent person, it’s relevant fluid and the system conditions:

• Every 12 to 14 months – Steam and hot water boilers operating under variable service conditions, and pressure vessels where rapid deterioration can be expected, as outlined in SAFed PSG 01.

• Every 24 to 26 months – Steam and hot water boilers operating under steady conditions, and pressure vessels potentially subject to rapid deterioration, as outlined in SAFed PSG 01 (e.g., Air receivers not regularly drained, shot blast vessels, Autoclaves & Steam jacketed pans).

• Every 26 to 48 months – Watertube steam boilers operating under the highest level of supervision, Pressure vessels not expected to deteriorate to danger within the examination frequency, as outlined in SAFed PSG 01 (e.g., Welded or solid drawn air receivers which are well maintained and regularly drained, Steam receivers associated with boilers on the same examination interval).
• Every 48 to 72 months – Pressure vessels not susceptible to significant deterioration, as outlined in SAFed PSG 01 (e.g., Air/oil receivers, Carbon dioxide storage vessels, Ammonia vessels abscent from stress corrosion cracking).
• Every 120 to 144 months – Examination intervals of 120-144 months would be appropriate for pressure vessels where there is extensive,
  documented experience of satisfactory operation for extended periods without deterioration, as outlined in SAFed PSG 01 (e.g., Stainless steel brewing vessels, class C compressed liquefileable gas and process vessel).

• After significant changes or repairs – Equipment must be inspected immediately if it has been modified, damaged, repaired or relocated.

• It should be noted that consideration should be given to an interim in-service examination under normal operating conditions at the mid-point of any examination period that exceeds 12-14 months.
