Why PSSR Inspections Matter for Businesses in Darlington

Darlington is a large market town in County Durham, North East England, with a strong historical link to transport and industry. The town grew from a small rural settlement into an important industrial centre during the early 19th century. Its development was shaped by innovation and trade, helping Darlington become one of the most influential towns in the region during the Industrial Revolution.

Darlington is best known for its role in the development of the modern railway. In 1825, the Stockton and Darlington Railway opened as the world’s first public railway to use steam locomotives. This achievement transformed the town into a major centre for railway engineering and manufacturing. Locomotive works and rail-related industries provided employment for thousands of people and encouraged rapid population growth.

Engineering and manufacturing remained central to Darlington’s economy throughout the 19th and early 20th centuries. The town became known for producing locomotives, railway equipment, and heavy machinery. Supporting industries, such as metalworking and mechanical engineering, developed alongside the railways, strengthening Darlington’s industrial base and regional importance.

In the late 20th century, traditional heavy industries declined, leading to economic challenges. In response, Darlington diversified its economy and invested in regeneration. Retail, public administration, education, healthcare, and professional services grew in importance. The town centre and retail parks now serve a wide rural hinterland, providing employment and services.

Today, Darlington has a mixed and resilient economy. Engineering and advanced manufacturing still play a role, supported by excellent transport links including the East Coast Main Line and the A1(M). Alongside this, service industries, logistics, and government offices provide stable employment. Darlington’s economy reflects a successful transition from heavy industrial roots to a modern, diverse economic base.

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 Darlington 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 Darlington – 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 Darlington 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.
