ABOUT

About This Sector

Engineering firms sit at a particularly demanding intersection of compliance. The workshop carries machinery, electrical, COSHH, noise, vibration, and manual handling risk simultaneously. The design office carries CDM 2015 design risk responsibility. The project team carries duty when working at client sites, often as principal designer or designer in CDM terms. Engineering employers routinely fail one of these three because they have built compliance for the workshop and overlooked design or project duty (or vice versa).

Arinite provides Qualified health and safety consultants and compliance software to engineering firms across the UK and 50+ countries, including consulting engineers, mechanical and electrical engineers, structural engineers, civil engineering contractors, building services engineers, and bespoke fabrication and prototype workshops.

COMPLIANCE GAPS

Common Compliance Failures We
Find in Engineering

These are the engineering health and safety failures Arinite's Qualified consultants find most frequently. Each one is a real exposure to HSE enforcement, civil claims, client audit failure, and director liability under Section 37 HSWA 1974.

Workshop risk assessment generic

Site-wide risk assessment covers the office but treats the workshop as a single activity. No discipline-by-discipline (welding, machining, electrical, fabrication) assessment.

No CDM 2015 designer competence evidence

Design work carried out without documented competence checks, design risk register, or pre-construction information capture.

PUWER assessments missing for workshop machinery

Bench drills, grinders, lathes, CNC equipment, welders, and pillar drills running without machine-specific risk assessment or guarding review.

LOLER register incomplete

Lifting accessories (eye bolts, lifting frames, slings) used in workshop and on site but not in the LOLER register.

Site work without documented client interface

Engineers attending client sites without confirmation of the client's risk assessment, permit requirements, or induction process.

No personal protective equipment programme

PPE supplied ad hoc without face fit testing for RPE, no documented selection rationale, no replacement cycle.

Mental health and psychosocial risk treated as HR-only

Long-hours culture, project deadline pressure, and isolation on remote sites overlooked as statutory psychosocial risk categories.

ENGINEERING WORKSHOP

Engineering Workshop
Risk Assessment

The engineering workshop is the highest-density risk environment most firms operate. A compliant workshop risk assessment under MHSWR Regulation 3 must address each discipline separately, not lump them into one generic workshop assessment.

Discipline-Specific Assessment

1

Machining (lathes, mills, drills, CNC)

Rotating machinery, ejection of swarf and tooling, entanglement, isolation procedures.

2

Welding (MIG, MAG, TIG, MMA, oxy-fuel)

Fume, UV exposure, hot work, gas safety, hot work permits.

3

Fabrication and cutting

Plasma cutting fume, sparks, hot metal handling, manual handling of stock.

4

Grinding and polishing

Dust generation, abrasive wheel safety, eye protection, hand-arm vibration.

5

Electrical assembly and testing

Live work risk, isolation, portable appliance testing.

6

Painting and surface finishing

Solvent COSHH, ventilation, fire safety, RPE.

7

Workshop transport

Forklifts, pallet trucks, overhead cranes, jib cranes.

8

Stores and racking

Manual handling, racking integrity, falling objects.

Workshop Documentation Pack

A compliant engineering workshop documentation pack includes machine-specific PUWER assessments, COSHH assessments for every substance and process-generated agent, noise assessment, LEV register, lifting equipment register, hot work permit system, abrasive wheel competence records, and PAT testing records. Arinite builds this pack as a single integrated set during onboarding.

CDM 2015

CDM 2015 Designer and
Principal Designer Duties

The Construction (Design and Management) Regulations 2015 place specific statutory duties on every designer and principal designer involved in construction work, including engineering consultancies and engineering design houses working on construction projects.

Designer Duties (Regulation 9)

1

Eliminate, reduce, or control foreseeable risks arising from the design.

2

Provide information about remaining risks to the principal designer, principal contractor, and ultimately to those carrying out the work and the eventual users of the structure.

3

Cooperate with other designers, the principal designer, and the principal contractor.

4

Confirm the client is aware of their duties.

Principal Designer Duties (Regulation 11-12)

Where the engineering firm is appointed as principal designer, additional duties apply:

1

Planning, managing, and monitoring the pre-construction phase.

2

Coordinating health and safety in design.

3

Compiling the pre-construction information for the principal contractor.

4

Preparing the health and safety file.

Documented Competence

CDM 2015 Regulation 8 requires that designers and principal designers must have the skills, knowledge, and experience to perform their roles. For engineering firms, this means documented competence at organisational and individual level: training records, CPD evidence, project portfolios, and where appropriate, professional registration (CEng, IEng, IMechE, IET, IStructE).

PROJECT SAFETY

Project Safety and Working
on Client Sites

Engineering firms regularly send personnel to client sites: factory installation, commissioning, site survey, fault diagnosis, plant maintenance, and witness testing. Each visit carries its own compliance footprint.

Pre-Visit Checks

1

Confirmation of the client's risk assessment and method statement for the work area.

2

Confirmation of any permit-to-work requirements (hot work, confined space, working at height, isolation).

3

Site induction arrangements.

4

PPE and RPE requirements at the client site.

5

Lone working and check-in arrangements where appropriate.

On-Site Documentation

The engineering firm's own risk assessment and method statement (RAMS) must be available on site, in addition to client-specific permits. Engineers should not begin work without both.

Insurance and Liability

Working on client sites does not transfer the employer's duty of care. The engineering firm retains primary responsibility for the safety of its own employees and bystanders affected by their work, regardless of any client permit-to-work or client RAMS.

EMPLOYER DUTIES

Core Employer Duties Under UK Engineering
Health and Safety Law

TYPICAL ENGAGEMENT

A Typical Engineering
Engagement With Arinite

The following is an illustrative example of how Arinite engagement typically runs for an engineering business.

A mid-market mechanical and electrical engineering consultancy with 140 employees, working across building services design, construction site supervision, and post-handover commissioning, approaches Arinite after a major principal contractor adds workplace H&S to its supplier review process and requests evidence of CDM 2015 designer duty discharge, current PI insurance, ISO 45001 status, and accident records for the past three years.
