3. Safety & Compliance Features
- Safe Emptying: Designed exclusively for use with triple-layer HepaFlo Filter Bags (NVM-2BH) which can be sealed shut, guaranteeing clean and safe disposal of hazardous waste without exposing the operator.
- Safe Containment:The vacuum comes equipped with screw-on dust caps for both the drum and the head. These caps enable the vacuum drum to be securely sealed when the machine is not in use or during transport, effectively preventing any hazardous materials from escaping the device.
- Certified Documentation Provided: Each machine includes official H-Class HEPA certification, which confirms compliance and ensures the integrity of filtration.
- Site Compliance: Ensuring complete compliance with EN 60335-2-69 (Annex AA) standards for managing hazardous dust.
The Numatic HZ370 H-Class Vacuum Cleaner is not a general-purpose vacuum; it is a specialised piece of Personal Protective Equipment (PPE) designed to ensure regulatory compliance and safeguard operator health when dealing with highly toxic materials.
🏭 Where the Numatic HZ370 Can Be Used (Applications)
The HZ370's H-Class certification makes it legally mandatory in environments where high-risk dusts are generated or encountered.
| Industry/Environment | Specific Applications |
| Construction & Demolition | Post-abatement cleanup, localised extraction when breaking/cutting hazardous materials, site cleanup of fine dust. |
| Building Restoration | Cleaning up lead paint residue (may require a specialist Type 22 machine for lead), mould remediation, and asbestos cleanup. |
| Workshops & Manufacturing | Vacuuming finely divided metallic dusts (e.g., Nickel, Chromium), chemical processing dusts, or high-volume fine wood dust from hardwoods or MDF. |
| Healthcare & Laboratories | Maintenance in older buildings where asbestos is present (e.g., pipe lagging), biohazard/pathogenic dust cleanup (must follow strict biohazard protocols). |
| Education & Maintenance | General cleanup and maintenance in older school or university buildings where legacy materials like asbestos or lead paint are risks. |
☣️ What Material the HZ370 is Certified to Collect
The HZ370 is certified to capture dusts with a Workplace Exposure Limit (WEL) of <0.1 mg/m3, which is the criterion for H-Class (High-Hazard) classification.
1. High-Hazard (H-Class) Materials
These materials pose the highest risk of long-term chronic or carcinogenic disease. The HZ370 is essential for their safe containment.
- Asbestos: Fibres released during removal, abatement, or disturbance of legacy materials (e.g., insulation, pipe lagging).
- Lead Dust: From sanding or disturbing old lead-based paint (Note: Type 22 machinery may be required for specific heavy lead collection).
- Carcinogenic & Toxic Dusts: Including some types of Mould Spores,
- Formaldehyde, Nickel, and Tar.
- Pathogenic Dusts & Bacteria
2. Medium-Hazard (M-Class) Materials
Although the HZ370 is H-Class, it is often recommended as the safest option for M-Class dusts to provide an extra layer of protection.
- Respirable Crystalline Silica (RCS): Released from cutting, grinding, or breaking Concrete, Brick, Grout, Cement, and Stone.
- Hardwood Dust: Dust generated from Oak, Beech, or MDF.
- Plaster and Gypsum Dust
-
Mineral Fibre and Glass Wood
What Accessories Are Included with the HZ370?
Included Accessories: The vacuum comes equipped with a comprehensive set of hand tools, a spare secondary filter, dust bags, and waste bags. This assortment enables you to tackle most cleaning tasks effectively.
Optional Accessories: We also provide an optional secondary floor tool kit, which simplifies floor cleaning. This kit is particularly useful for end-of-day cleanups at job sites or in workshops.
💡 Why Purchase the HZ370 (The H-Class Difference)
The decision to purchase an H-Class machine is driven by legal compliance, operator safety, and risk mitigation.
- Legal Compliance (COSHH)The HZ370 meets the minimum legal requirement advised by the HSE for handling high-risk dusts under COSHH (Control of Substances Hazardous to Health) regulations.
- Absolute Containment: The sealed H-Class system, featuring the HEPA H13 filter module and self-sealing HepaFlo bags, guarantees that 99.95% of particles are trapped and contained, preventing recirculation back into the air.
- Worker Protection: It fundamentally reduces the risk of long-term operator health issues by removing harmful airborne particles at the source.
Understanding H-Class Vacuum Cleaners: Safety & Compliance Explained
In industrial and specialist environments where dust is not just a nuisance but a life-threatening hazard—such as asbestos removal, lead abatement, or pharmaceutical manufacturing—even M-Class equipment is not enough. For the most dangerous airborne particles, H-Class vacuum cleaners are the only legally compliant and safe solution.
What is an H-Class Vacuum Cleaner?
H-Class (High-Hazard Class) is the highest international safety standard for professional dust extraction. While M-Class vacuums are designed for medium-risk dusts, H-Class machines are engineered to contain highly carcinogenic, pathogenic, and toxic materials.
A vacuum certified to H-Class standards is guaranteed to capture at least 99.995% of the dust it processes. These machines utilize HEPA H14 filtration (the highest grade) and are built with fully sealed chassis. Unlike standard vacuums, every H-Class unit is individually tested and certified to ensure no hazardous fibres can bypass the filter or leak through the casing.
Why Are H-Class Vacuums Important?
When dealing with "High-Hazard" materials, the margin for error is zero. Using H-Class equipment is a mandatory requirement for specialized sectors:
- Maximum Health Protection: H-Class vacuums are designed to trap microscopic particles like asbestos fibres and lead dust, which can cause terminal illnesses such as mesothelioma, lung cancer, and systemic poisoning.
- Legal Compliance (COSHH & HSE): In the UK, the Health and Safety Executive (HSE) and COSHH regulations mandate H-Class extraction for any material with a Workplace Exposure Limit (WEL) of less than 0.1 mg/m³. Failure to use certified equipment can lead to massive fines, site closures, and legal prosecution.
- Strict Containment & Disposal: H-Class vacuums feature "low-dust" or "dust-free" bag change systems. This ensures that when the vacuum is full, workers are not exposed to a "dust cloud" during disposal—a common failure point in lesser machines.
- Acoustic & Visual Safety Alarms: To comply with BS EN 60335-2-69, these machines include integrated sensors that trigger an audible alarm if the airflow drops below 20m/s, alerting the operator to a blockage or filter saturation immediately.
Materials Requiring H-Class Collection
H-Class vacuums are required for dusts contaminated with carcinogens, pathogens, or toxic substances where the exposure limit is extremely low.
| Material Type | Common Sources & Hazards |
| Asbestos | Licensed and non-licensed removal of lagging, floor tiles, and textured coatings. |
| Lead Dust | Stripping lead-based paints, renovation of heritage buildings, or firing range maintenance. |
| Silica (RCS) | High-intensity grinding or cutting of stone and concrete (where H-Class provides a higher safety margin than M-Class). |
| Carcinogenic Dusts | Processing of materials containing bitumen, tar, nickel, cobalt, copper, or cadmium. |
| Pathogenic Hazards | Mould spores, bacteria, germs, and pharmaceutical waste in lab or clinical settings. |
| Highly Toxic Finishes | Sanding of certain chemical-heavy coatings, resins, and formaldehyde-based materials. |
⚠️ Important Safety Note: H-Class Compliance
H-Class extraction is a life-safety requirement. Because exposure to toxic, carcinogenic, or pathogenic dusts (such as asbestos or respirable crystalline silica) can lead to fatal respiratory diseases, a formal COSHH Risk Assessment must be conducted to determine the correct filtration level for your specific materials.
Standard industrial vacuums are not sufficient for high-hazard environments. For official UK guidance on the selection and use of H-Class equipment, please refer to the HSE Usin a H-Class Vacuum Cleaner page.
