Hazard Control for the Defence Sector

RVT Group provides rapid-response hazard control solutions for urgent defence projects, ensuring that unexpected repairs do not compromise operational continuity or national security. We handle fast installation and commissioning, so work can proceed safely without delaying critical operations. This approach ensures that personnel are protected, compliance is maintained, and sensitive defence activities remain secure and uninterrupted. We have a dedicated team based at Plymouth dockyard and Portsmouth dockyard who are readily available to help should an urgent situation arise.

We deliver end-to-end hazard control support for the defence sector, including:

• Design and consultation
• Site training if required
• Installation and commissioning
• Maintenance throughout the hire
• Dismantling and removal once work is complete

This ensures that solutions are properly tailored, compliant, and effective throughout the project lifecycle.

Yes, we can provide ventilation solutions for use in potentially explosive atmospheres ATEX zones 1-21, such as VENTEX® Centrifugal Fan 300M ATEX. We also offer ATEX & IECEx rated hand torches and head torches.

• Reduce project risk by safely minimising exposure to harmful dust and fumes.
• Protect worker health with compliant, effective engineering controls.
• Keep projects on schedule with rapid response and expert support.
• Ensure regulatory compliance with systems designed to meet standards.
• Get tailored solutions for complex, unique marine and defence worksites.

We support control of dust (e.g. fibreglass sanding), harmful fumes (from welding, cutting and painting), poor ventilation, noise and temperature issues that arise during ship building or repair.

Yes, we manage delivery, installation, commissioning and ongoing technical support through to dismantling, ensuring the system performs as expected throughout your project.

An RVT Group hazard control risk assessment is a comprehensive review of your work environment, processes, and potential risks. Conducted by an experienced and qualified consultant, it includes:

Identifying potential hazards: We examine your current or upcoming activities to pinpoint risks such as dust, fumes, confined space hazards, noise, and temperature extremes.

Best practice guidance: Our consultant provides actionable advice based on defence industry standards, HSE guidance, and proven hazard control methods.

Tailored hazard control hire solutions: We propose practical measures, including engineering controls, ventilation, dust suppression systems, fume extraction, and other relevant interventions.

Compliance assurance: The assessment ensures that your operations meet all relevant legislation and health and safety regulations.

Detailed proposal: You receive a full report with recommended actions, system specifications, and implementation strategies designed to protect workers and reduce operational risk.

Optional follow-up support: We can assist with installation, commissioning, maintenance, and monitoring to ensure solutions are fully effective throughout the project lifecycle.

Absolutely, we offer a free hazard control risk assessment with a specialist technical consultant dedicated to supporting the defence sector, to help identify your needs and recommend the right solution, via phone, Teams, or on-site visit.

Relative humidity (RH) is how much moisture is present in the air, compared to the maximum there could be. Projects can be affected by RH, especially if carrying out painting, coating or waiting for adhesion to dry. High humidity can lead to drying too quickly, causing peeling, bubbles, and uneven finishes. However, low humidity can slow down the drying process, resulting in poor adhesion and uneven drying. Effective heating or drying-out can prevent these issues from arising.

RVT group utilise a unique specification of PVC hose, which we typically use to support with providing fresh air, dust extraction, and paint and fume extraction. Quick release couplers can be used to safeguard high risk areas on a naval ship such as compartments below the water line, or areas that are locked up after work has been carried out.

Our PVC Hose offers more than one benefit:

• Increased air velocity due to the smooth bore inside.
• It’s tough, flexible, and durable that can last in tough conditions.
• Provide an increase in performance meaning less hosing is required.
• UL94V-0 Rated flame retardancy meaning no helix is left behind.
• Can out perform ducting of its same size by more than 30%.

ATEX approved equipment is essential for ensuring the safety of personnel in environments where flammable gases, mists or vapours, or combustible dust are present as it prevents providing a source for ignition. Dockyards, aircraft hangars and more Ministry of Defence bases often require ATEX approved equipment.

Grit blasting is the process where a stream of abrasive particles at high pressure is aimed directly against a surface to remove contaminants, rust, dirt, or old coatings. When ships are docked for maintenance or repair works, grit blasting is often an essential activity carried out.

Grit blasting can have a lasting impact on someone's health, both physically and mentally if no suitable control measures are in place. Risks include inhaling abrasive materials leading to long term health issues including silicosis, COPD and cancer, or exposure to the noise from the activity leading to hearing damage.

The speed in which paint comes out within spray form means it quickly builds up within a space and can form high vapour levels.

The spraying technique breaks down paint into fine droplets during the application, therefore a greater amount stays airborne and is more susceptible to be breathed in. Short-term effects of inhalation include dizziness and nausea. Prolonged exposure can lead to serious health effects such as lung and liver damage, and even cancer.

We design and install systems that meet regulatory and best practice guidance such as COSHH regulations and HSE ventilation standards. Each LEV solution is commissioned and tested (TExT) before use.

Yes, our solutions are suitable for confined spaces found on ships and submarines, helping control airborne contaminants and ensure safe working conditions in enclosed spaces.

RVT Group provides hazard control solutions for marine related defence and naval maintenance projects, including ship build, repair and refurbishment activities where dust, fumes, ventilation and climate control are required.
